I love that featherlike structure holding up a tiny block of something while balanced on what appears to be a series of medallions. What it has to do with supercapacitors (energy storage) and cellulose nanocrystals is a mystery but that’s one of the images you’ll find illustrating an Oct. 7, 2015 news item on Nanotechnology Now featuring research at McMaster University,
McMaster Engineering researchers Emily Cranston and Igor Zhitomirsky are turning trees into energy storage devices capable of powering everything from a smart watch to a hybrid car.
The scientists are using cellulose, an organic compound found in plants, bacteria, algae and trees, to build more efficient and longer-lasting energy storage devices or supercapacitors. This development paves the way toward the production of lightweight, flexible, and high-power electronics, such as wearable devices, portable power supplies and hybrid and electric vehicles.
Cellulose offers the advantages of high strength and flexibility for many advanced applications; of particular interest are nanocellulose-based materials. The work by Cranston, an assistant chemical engineering professor, and Zhitomirsky, a materials science and engineering professor, demonstrates an improved three-dimensional energy storage device constructed by trapping functional nanoparticles within the walls of a nanocellulose foam.
The foam is made in a simplified and fast one-step process. The type of nanocellulose used is called cellulose nanocrystals and looks like uncooked long-grain rice but with nanometer-dimensions. In these new devices, the ‘rice grains’ have been glued together at random points forming a mesh-like structure with lots of open space, hence the extremely lightweight nature of the material. This can be used to produce more sustainable capacitor devices with higher power density and faster charging abilities compared to rechargeable batteries.
Lightweight and high-power density capacitors are of particular interest for the development of hybrid and electric vehicles. The fast-charging devices allow for significant energy saving, because they can accumulate energy during braking and release it during acceleration.
For anyone interested in a more detailed description of supercapacitors, there’s my favourite one which involves Captain America’s shield along with some serious science in my April 28, 2014 posting.
Getting back to the research at McMaster, here’s a link to and a citation for the paper,
I’m pretty sure I’ve said this before but a repetition can’t hurt, “I love glass both for the art and the mystery.” Naturally, I am of two minds about this ‘shattered’ glass mystery from the University of Waterloo (Canada).
A physicist at the University of Waterloo is among a team of scientists who have described how glasses form at the molecular level and provided a possible solution to a problem that has stumped scientists for decades.
Their simple theory is expected to open up the study of glasses to non-experts and undergraduates as well as inspire breakthroughs in novel nanomaterials.
The paper published by physicists from the University of Waterloo, McMaster University, ESPCI ParisTech and Université Paris Diderot appeared in the prestigious peer-reviewed journal, Proceedings of the National Academy of Sciences (PNAS).
Glasses are much more than silicon-based materials in bottles and windows. In fact, any solid without an ordered, crystalline structure — metal, plastic, a polymer — that forms a molten liquid when heated above a certain temperature is a glass. Glasses are an essential material in technology, pharmaceuticals, housing, renewable energy and increasingly nano electronics.
“We were surprised — delighted — that the model turned out to be so simple,” said author James Forrest, a University Research Chair and professor in the Faculty of Science. “We were convinced it had already been published.”
The theory relies on two basic concepts: molecular crowding and string-like co-operative movement. [emphasis mine] Molecular crowding describes how molecules within glasses move like people in a crowded room. As the number of people increase, the amount of free volume decreases and the slower people can move through the crowd. Those people next to the door are able to move more freely, just as the surfaces of glasses never actually stop flowing, even at lower temperatures.
The more crowded the room, the more you rely on the co-operative movement with your neighbours to get where you’re going. Likewise, individual molecules within a glass aren’t able to move totally freely. They move with, yet are confined by, strings of weak molecular bonds with their neighbours.
Theories of crowding and cooperative movement are decades old. This is the first time scientists combined both theories to describe how a liquid turns into a glass.
“Research on glasses is normally reserved for specialists in condensed matter physics,” said Forrest, who is also an associate faculty member at Perimeter Institute for Theoretical Physics and a member of the Waterloo Institute for Nanotechnology. “Now a whole new generation of scientists can study and apply glasses just using first-year calculus.”
Their theory successfully predicts everything from bulk behaviour to surface flow to the once-elusive phenomenon of the glass transition itself. Forrest and colleagues worked for 20 years to bring theory in agreement with decades of observation on glassy materials.
An accurate theory becomes particularly important when trying to understand glass dynamics at the nanoscale. This finding has implications for developing and manufacturing new nanomaterials, such as glasses with conductive properties, or even calculating the uptake of glassy forms of pharmaceuticals.

Cooperative strings and glassy interfaces by Thomas Salez, Justin Salez, Kari Dalnoki-Veress, Elie Raphaël, and James A. Forrest. PNAS (Proceedings of the National Academy of Sciences) Published online before print June 22, 2015, doi: 10.1073/pnas.1503133112
Having once spent several months doing a literature search on pain and morphine, I have a particular interest in this breakthrough from McMaster University (Canada) announced in a May 21, 2015 news item on ScienceDaily,
Scientists at McMaster University have discovered how to make adult sensory neurons from human patients simply by having them roll up their sleeve and providing a blood sample.
Specifically, stem cell scientists at McMaster can now directly convert adult human blood cells to both central nervous system (brain and spinal cord) neurons as well as neurons in the peripheral nervous system (rest of the body) that are responsible for pain, temperature and itch perception. This means that how a person’s nervous system cells react and respond to stimuli, can be determined from his blood.
Currently, scientists and physicians have a limited understanding of the complex issue of pain and how to treat it. The peripheral nervous system is made up of different types of nerves – some are mechanical (feel pressure) and others detect temperature (heat). In extreme conditions, pain or numbness is perceived by the brain using signals sent by these peripheral nerves.
“The problem is that unlike blood, a skin sample or even a tissue biopsy, you can’t take a piece of a patient’s neural system. It runs like complex wiring throughout the body and portions cannot be sampled for study,” said Bhatia [Mick Bhatia, director of the McMaster Stem Cell and Cancer Research Institute and much more].
“Now we can take easy to obtain blood samples, and make the main cell types of neurological systems – the central nervous system and the peripheral nervous system – in a dish that is specialized for each patient,” said Bhatia. “Nobody has ever done this with adult blood. Ever.
“We can actually take a patient’s blood sample, as routinely performed in a doctor’s office, and with it we can produce one million sensory neurons, that make up the peripheral nerves in short order with this new approach. We can also make central nervous system cells, as the blood to neural conversion technology we developed creates neural stem cells during the process of conversion.”
His team’s revolutionary, patented direct conversion technology has “broad and immediate applications,” said Bhatia, adding that it allows researchers to start asking questions about understanding disease and improving treatments such as: Why is it that certain people feel pain versus numbness? Is this something genetic? Can the neuropathy that diabetic patients experience be mimicked in a dish?
It also paves the way for the discovery of new pain drugs that don’t just numb the perception of pain. Bhatia said non-specific opioids used for decades are still being used today.
“If I was a patient and I was feeling pain or experiencing neuropathy, the prized pain drug for me would target the peripheral nervous system neurons, but do nothing to the central nervous system, thus avoiding non-addictive drug side effects,” said Bhatia.
“You don’t want to feel sleepy or unaware, you just want your pain to go away. But, up until now, no one’s had the ability and required technology to actually test different drugs to find something that targets the peripheral nervous system and not the central nervous system in a patient specific, or personalized manner.”
Bhatia’s team successfully tested their process using fresh blood, but also cryopreserved (frozen) blood. Since blood samples are taken and frozen with many clinical trials, this allows them “almost a bit of a time machine” to go back and explore questions around pain or neuropathy to run tests on neurons created from blood samples of patients taken in past clinical trials where responses and outcomes have already been recorded”.
In the future, the process may have prognostic potential, explained Bhatia, in that one might be able to look at a patient with Type 2 Diabetes and predict whether they will experience neuropathy by running tests in the lab using their own neural cells derived from their blood sample.
“This bench to bedside research is very exciting and will have a major impact on the management of neurological diseases, particularly neuropathic pain,” said Akbar Panju, medical director of the Michael G. DeGroote Institute for Pain Research and Care, a clinician and professor of medicine.
“This research will help us understand the response of cells to different drugs and different stimulation responses, and allow us to provide individualized or personalized medical therapy for patients suffering with neuropathic pain.”

As of May 11, 2015, Canadians will be getting an addition to their science media environment (from the May 4, 2015 news release),
Research2Reality to celebrate Canadian research stars
Social media initiative to popularize scientific innovation
May 4, 2015, TORONTO – On Monday, May 11, Research2Reality.com goes live and launches a social media initiative that will make the scientist a star. Following in the footsteps of popular sites like IFLScience and How Stuff Works, Research2Reality uses a video series and website to engage the community in the forefront of scientific discoveries made here in Canada.
…
The interviews feature some of Canada’s leading researchers such as Dick Peltier – director of the Centre for Global Change Science at the University of Toronto, Sally Aitken – director of the Centre for Forest Conservation Genetics at the University of British Columbia and Raymond Laflamme – executive director of the Institute for Quantum Computing at the University of Waterloo.
“Right now many Canadians don’t understand the scope of cutting-edge work being done in our backyards,” says Research2Reality co-founder and award-winning professor Molly Shoichet. “This initiative will bridge that gap between researchers and the public.”
Also launching Monday, May 11, courtesy of Research2Reality’s official media partner, Discovery Science, is a complementary website www.sciencechannel.ca/Shows/Research2Reality. The new website will feature the exclusive premieres of a collection of interview sessions. In addition, Discovery Science and Discovery will broadcast an imaginative series of public service announcements through the end of the year, while social media accounts will promote Research2Reality, including Discovery’s flagship science and technology program DAILY PLANET.
…
About Research2Reality:
Research2Reality is a social media initiative designed to popularize the latest Canadian research. It was founded by Molly Shoichet, Professor of Chemical Engineering & Applied Chemistry and Canada Research Chair in Tissue Engineering at the University of Toronto, and Mike MacMillan, founder and producer of Lithium Studios Productions. Research2Reality’s founding partners are leading research-intensive universities – the University of Alberta, the University of British Columbia, McMaster University, the University of Toronto, the University of Waterloo, and Western University – along with the Ontario Government and Discovery Networks. Discovery Science is the official media partner. Research2Reality is also supported by The Globe and Mail.
Research2Reality details
A Valentine of sorts to Canadian science researchers from Molly Shoichet (pronounced shoy [and] quette as in David Arquette) and her producing partner Mike MacMillan of Lithium Studios, Research2Reality gives Canadians an opportunity to discover online some of the extraordinary work done by scientists of all stripes, including (unusually) social scientists, in this country. The top tier in this effort is the interview video series ‘The Orange Chair Sessions‘ which can be found and shared across
Shoichet and MacMillan are convinced there’s an appetite for more comprehensive science information. Supporting The Orange Chair Sessions is a complementary website operated by Discovery Channel where there are
more interviews
backgrounders,
biographies,
blogs, and
links to other resources
Discovery Channel is also going to be airing special one minute public service announcements (PSA) on topics like water, quantum computing, and cancer. Here’s one of the first of those PSAs,
“I’m very excited about this and really hope that other people will be too,” says Shoichet. The audience for the Research2Reality endeavour is for people who like to know more and have questions when they see news items about science discoveries that can’t be answered by investigating mainstream media programmes or trying to read complex research papers.
This is a big undertaking. ” Mike and I thought about this for about two years.” Building on the support they received from the University of Toronto, “We reached out to the vice-presidents of research at the top fifteen universities in the country.” In the end, six universities accepted the invitation to invest in this project,
the University of British Columbia,
the University of Alberta,
Western University (formerly the University of Western Ontario),
McMaster University,
Waterloo University, and, of course,
the University of Toronto
(Unfortunately, Shoichet was not able to answer a question about the cost for an individual episode but perhaps when there’s time that detail and more about the financing will be made available. [ETA May 11, 2015 1625 PDT: Ivan Semeniuk notes this is a $400,000 project in his Globe and Mail May 11, 2015 article.]) As part of their involvement, the universities decide which of their researchers/projects should be profiled then Research2Reality swings into action. “We shoot our own video, that is, we (Mike and I) come out and conduct interviews that take approximately fifteen minutes. We also shoot a b-roll, that is, footage of the laboratories and other relevant sites so it’s not all ‘talking heads’.” Shoichet and MacMillan are interested in the answer to two questions, “What are you doing? and Why do we care?” Neither interviewer/producer is seen or heard on camera as they wanted to keep the focus on the researcher.
Three videos are being released initially with another 67 in the pipeline for a total of 70. The focus is on research of an international calibre and one of the first interviews to be released (Shoichet’s will be release later) is Raymond Laflamme’s (he’s also featured in the ‘quantum PSA’.
Raymond Laflamme
Who convinces a genius that he’s gotten an important cosmological concept wrong or ignored it? Alongside Don Page, Laflamme accomplished that feat as one of Stephen Hawking’s PhD students at the University of Cambridge. Today (May 11, 2015), Laflamme is (from his Wikipedia entry)
… co-founder and current director of the Institute for Quantum Computing at the University of Waterloo. He is also a professor in the Department of Physics and Astronomy at the University of Waterloo and an associate faculty member at Perimeter Institute for Theoretical Physics. Laflamme is currently a Canada Research Chair in Quantum Information.
Laflamme changed his focus from quantum cosmology to quantum information while at Los Alamos, “To me, it seemed natural. Not much of a change.” It is the difference between being a theoretician and an experimentalist and anyone who’s watched The Big Bang Theory (US television programme) knows that Laflamme made a big leap.
One of his major research interests is quantum cryptography, a means of passing messages you can ensure are private. Laflamme’s team and a team in Vienna (Austria) have enabled two quantum communication systems, one purely terrestrial version, which can exchange messages with another such system up to 100 km. away. There are some problems yet to be solved with terrestrial quantum communication. First, buildings, trees, and other structures provide interference as does the curvature of the earth. Second, fibre optic cables absorb some of the photons en route.
Satellite quantum communication seems more promising as these problems are avoided altogether. The joint Waterloo/Vienna team of researchers has conducted successful satellite experiments in quantum communication in the Canary Islands.
While there don’t seem to be any practical, commercial quantum applications, Laflamme says that isn’t strictly speaking the truth, “In the last 10 to 15 years many ideas have been realized.” The talk turns to quantum sensing and Laflamme mentions two startups and notes he can’t talk about them yet. But there is Universal Quantum Devices (UQD), a company that produces parts for quantum sensors. It is Laflamme’s startup, one he co-founded with two partners. (For anyone unfamiliar with the Canadian academic scene, Laflamme’s home institution, the University of Waterloo, is one of the most actively ‘innovative’ and business-oriented universities in Canada.)
LaFlamme’s interests extend beyond laboratory work and business. He’s an active science communicator as can be seen in this 2010 TEDxWaterloo presentation where he takes his audience from the discovery of fire to quantum physics concepts such as a ‘quantum superposition’ and the ‘observer effect’ to the question, ‘What is reality?’ in approximately 18 mins.
For anyone who needs a little more information, a quantum superposition is a term referring the ability of a quantum object to inhabit two states simultaneously, e.g., on/off. yes/no, alive/dead, as in Schrödinger’s cat. (You can find out more about quantum superpositions in this Wikipedia essay and about Schrodinger’s cat in this Wikipedia essay.) The observer effect is a phenomenon whereby the observer of a quantum experiment affects that experiment by the act of observing it. (You can find out more about the observer effect in this Wikipedia essay.)
The topic of reality is much trickier to explain. No one has yet been able to offer a viable theory for why the world at the macro scale behaves one way (classical physics) and the world at the quantum scale behaves another way (quantum physics). As Laflamme notes, “There is no such thing as a superposition in classical physics but we can prove in the laboratory that it exists in quantum physics.” He goes on to suggest that children, raised in an environment where quantum physics and its applications are commonplace, will have an utterly different notion as to what constitutes reality.
Laflamme is also interested in music and consulted on a ‘quantum symphony’. He has this to say about it in an Sept. 20, 2012 piece on the University of Waterlo website,
Science and art share a common goal — to help us understand our universe and ourselves. Research at IQC [Institute for Quantum Computing] aims to provide important new understanding of nature’s building blocks, and devise methods to turn that understanding into technologies beneficial for society.Since founding IQC a decade ago, I have sought ways to bridge science and the arts, with the belief that scientific discovery itself is a source of beauty and inspiration. Our collaboration with the Kitchener-Waterloo Symphony was an example — one of many yet to come — of how science and the arts provide different but complementary insights into our universe and ourselves.
I wrote about the IQC and the symphony which debuted at the IQC’s opening in a Sept. 25, 2012 posting.
Music is not the only art which has attracted Laflamme’s talents. He consulted on a documentary, The Quantum Tamers: Revealing our weird and wired future, a co-production between Canada’s Perimeter Institute and Title Entertainment,
From deep inside the sewers of Vienna, site of groundbreaking quantum teleportation experiments, to cutting-edge quantum computing labs, to voyages into the minds of the world’s brightest thinkers, including renowned British scientist Stephen Hawking, this documentary explores the coming quantum technological revolution.
All of this suggests an interest in science not seen since the 19th century when scientists could fill theatres for their lectures. Even Hollywood is capitalizing on this interest. Laflamme, who saw ‘Interstellar’, ‘The Imitation Game’ (Alan Turing), and ‘The Theory of Everything’ (Stephen Hawking) in fall 2014 comments, “I was surprised by how much science there was in The Imitation Game and Interstellar.” As for the Theory of Everything, “I was apprehensive since I know Stephen well. But, the actor, Eddie Redmayne, and the movie surprised me. There were times when he moved his head or did something in a particular way—he was Stephen. Also, most people don’t realize what an incredible sense of humour Stephen has and the movie captured that well.” Laflamme also observed that it was a movie about a relationship and not really concerned with science and its impacts (good and ill) or scientific accomplishments. Although he allows, “It could have had more science.”

Final comments
It’s nice to see the Canadian scene expanding; I’m particularly pleased to learn social scientists will be included.Too often researchers from the physical sciences or natural sciences and researchers from the social sciences remain aloof from each other. In April 2013, I attended a talk by Evelyn Fox Keller, physicist, feminist, and philosopher, who read from a paper she’d written based on a then relatively recent experience in South Africa where researchers had aligned themselves in two different groups and refused to speak to each other. They were all anthropologists but the sticking point was the type of science they practiced. One group were physical anthropologists and the other were cultural anthropologists. That’s an extreme example unfortunately symptomatic of a great divide. Bravo to Research2Reality for bringing the two groups together.
As for the science appetite Shoichet and MacMillan see in Canada, this is not the only country experiencing a resurgence of interest; they’ve been experiencing a science media expansion in the US. Neil deGrasse Tyson’s Star Talk television talk show, which also exists as a radio podcast, debuted on April 19, 2015 (Yahoo article by Calla Cofield); Public Radio Exchange’s (PRX) Transistor; a STEM (science, technology, engineering, and mathematics) audio project debuted in Feb. 2015; and video podcast Science Goes to the Movies also debuted in Feb. 2015 (more about the last two initiatives in my March 6, 2015 posting [scroll down about 40% of the way]). Finally (for the burgeoning US science media scene) and neither least nor new, David Bruggeman has a series of posts titled, Science and Technology Guests on Late Night, Week of …, on his Pasco Phronesis blog which has been running for many years. Bruggeman’s series is being included here because most people don’t realize that US late night talk shows have jumped into the science scene. You can check David’s site here as he posts this series on Mondays and this is Monday, May 11, 2015.
It’s early days for Research2Reality and it doesn’t yet have the depth one might wish. The videos are short (the one featured on the Discovery Channel’s complementary website is less than 2 mins. and prepare yourself for ads). They may not be satisfying from an information perspective but what makes The Orange Chair Series fascinating is the peek into the Canadian research scene. Welcome to Research2Reality and I hope to hear more about you in the coming months.
[ETA May 11, 2015 at 1625 PDT: Semeniuk’s May 11, 2015 article mentions a few other efforts to publicize Canadian research (Note: Links have been removed),
For example, Research Matters, a promotional effort by the Council of Ontario Universities, has built up a large bank of short articles on its website that highlight researchers across the province. Similarly, the Canada Foundation for Innovation, which channels federal dollars toward research infrastructure and projects, produces features stories with embedded videos about the scientists who are enabled by their investments.
What makes Research2Reality different, said Dr. Shoichet, is an approach that doesn’t speak for one region, field of research of [sic] funding stream.
One other aspect which distinguishes Research2Reality from the other science promotion efforts is the attempt to reach out to the audience. The Canada Foundation for Innovation and Council for Ontario Universities are not known for reaching out directly to the general public.]
A new UN report warns that without large new water-related investments many societies worldwide will soon confront rising desperation and conflicts over life’s most essential resource.
The news release describes the situation,
Continued stalling, coupled with population growth, economic instability, disrupted climate patterns and other variables, could reverse hard-earned development gains and preclude meaningful levels of development that can be sustained into the future.
Says lead author Bob Sandford, EPCOR Chair, Canadian Partnership Initiative in support of the UN Water for Life Decade: “The consequence of unmet water goals will be widespread insecurity creating more international tension and conflict. The positive message is that if we can keep moving now on water-related Sustainable Development Goals we can still have the future we want.”
Published in the run-up to the adoption this September of universal post-2015 Sustainable Development Goals (SDGs), the report provides an in-depth analysis of 10 countries to show how achieving water and sanitation-related SDGs offers a rapid, cost effective way to achieve sustainable development.
The 10 countries given the analysis are not the ‘usual suspects’ (from the news release),
The countries included in the study cover the full range of economic and development spectrum: Bangladesh, Bolivia, Canada, Indonesia, Republic of Korea, Pakistan, Singapore, Uganda, Vietnam, and Zambia.
Based on the national case studies, the report prescribes country level steps for achieving the global water targets.
No US. No China. No Middle Eastern countries. No Australia. No India. No Japan. No European countries. There is one North American country, two African countries and one South American country in addition to the Asian countries. To my knowledge none of the included countries is strongly associated with desert regions.
It’s an interesting set of choices and the report offers no explanation as to why these 10 countries rather than 10 others. You can check if for yourself on p. 29 (the introductory first page of Part Three: Learning from National Priorities and Strategies) of the 2015 Water in the World We Want report.
Water scarcity hurts everybody
Moving on to the report’s recommendations as noted in the news release,
Among top recommendations: Hold the agriculture sector (which guzzles roughly 70% of world water supplies), and the energy sector (15%), accountable for making efficiencies while transitioning to clean energy including hydropower.
Prepared in association with the Global Water Partnership and Canada’s McMaster University, the report says the success of global efforts on the scale required rests in large part on a crackdown on widespread corruption in the water sector, particularly in developing countries.
“In many places … corruption is resulting in the hemorrhaging of precious financial resources,” siphoning an estimated 30% of funds earmarked for water and sanitation-related improvements.
The report underscores the need for clearly defined anti-corruption protocols enforced with harsh penalties.
Given accelerating Earth system changes and the growing threat of hydro-climatic disruption, corruption undermining water-related improvements threatens the stability and very existence of some nation states, which in turn affects all other countries, the report says.
“Corruption at any level is not just a criminal act in its own right. In the context of sustainable development it could be viewed as a crime against all of humanity.”
The report notes that the world’s water and wastewater infrastructure maintenance and replacement deficit is building at a rate of $200 million per year, with $1 trillion now required in the USA alone.
To finance its recommendations, the report says that, in addition to plugging the leakage of funds to corruption, $1.9 trillion in subsidies to petroleum, coal and gas industries should be redirected by degrees.
The estimated global cost to achieve post-2015 sustainable development goals in water and sanitation development, maintenance and replacement is US $1.25 trillion to $2.25 trillion per year for 20 years, a doubling or tripling of current spending translating into 1.8 to 2.5 percent of global GDP.
The resulting benefits would be commensurately large, however – a minimum of $3.11 trillion per year, not counting health care savings and valuable ecosystem service enhancements.
Changes in fundamental hydrology “likely to cause new kinds of conflict”
Sandford and co-lead author Corinne J. Schuster-Wallace of UNU-INWEH underline that all current water management challenges will be compounded one way or another by climate change, and by increasingly unpredictable weather.
“Historical predictability, known as relative hydrological stationarity … provides the certainty needed to build houses to withstand winds of a certain speed, snow of a certain weight, and rainfalls of certain intensity and duration, when to plant crops, and to what size to build storm sewers. The consequence is that the management of water in all its forms in the future will involve a great deal more uncertainty than it has in the past.”
“In a more or less stable hydro-climatic regime you are playing poker with a deck you know and can bet on risk accordingly. The loss of stationarity is playing poker with a deck in which new cards you have never seen before keep appearing more and more often, ultimately disrupting your hand to such an extent that the game no longer has coherence or meaning.”
“People do not have the luxury of living without water and when faced with a life or death decision, people tend to do whatever they must to survive … Changes in fundamental hydrology are likely to cause new kinds of conflict, and it can be expected that both water scarcity and flooding will become major trans-boundary water issues.”
Within 10 years, researchers predict 48 countries – 25% of all nations on Earth with an expected combined population of 2.9 billion – will be classified “water-scarce” (1,000 to 1,700 cubic meters of water per capita per year) or “water-stressed” (1,000 cubic meters or less). [emphases mine]
And by 2030, expect overall global demand for freshwater to exceed supply by 40%, with the most acute problems in warmer, low-resource nations with young, fast-growing populations, according to the report. [emphasis mine]
An estimated 25% of the world’s major river basins run dry for part of each year, the report notes, and “new conflicts are likely to emerge as more of the world’s rivers become further heavily abstracted so that they no longer make it to the sea.”
Meanwhile, the magnitude of floods in Pakistan and Australia in 2010, and on the Great Plains of North America in 2011 and 2014, “suggests that the destruction of upstream flood protection and the failure to provide adequate downstream flood warning will enter into global conflict formulae in the future.”
The report cites the rising cost of world flood-related damages: US$53 billion in 2013 and more than US$312 billion since 2004.
Included in the global flood figures: roughly $1 billion in flood damage in the Canadian province of Manitoba in both 2011 and 2014. The disasters have affected the province’s economic and political stability, contributing to a budget deficit, an unpopular increase in the provincial sales tax and to the consequent resignation of political leaders. [emphases mine]
UNU-INWEH Director Zafar Adeel and Jong Soo Yoon, Head of the UN Office for Sustainable Development, state: “Through a series of country case studies, expert opinion, and evidence synthesis, the report explores the critical role that water plays (including sanitation and wastewater management) in sustainable development; current disconnects between some national development plans and the proposed SDGs; opportunities for achieving sustainable development through careful water management; and implementation opportunities.”
The report, they add, “fills a critical gap in understanding the complexities associated with water resources and their management, and also provides substantive options that enable us to move forward within the global dialogue.”
Juxtaposing the situation in Manitoba with the situation in warmer, low-resource nations emphasizes the universality of the problem. Canadians can be complacent about water scarcity, especially where I live in the Pacific Northwest, but it affects us all.
Corruption bites everywhere
As for the corruption mentioned in the news release and report, while there is no news of ‘water’ corruption here, the country does have its own track record with regard to financial boondoggles. For example, the Auditor-General reported in 2013 that $3.1B spent on measures to combat terrorism was unaccounted for (from an April 30, 2013 Globe & Mail article by Gloria Galloway and Daniel Leblanc),
The federal government cannot account for billions of dollars that were devoted to combatting terrorism after the Sept. 11 [2001] attacks, Canada’s Auditor-General says in a new report.
Between 2001 and 2009, Ottawa awarded $12.9-billion to 35 departments and agencies charged with ensuring the safety of Canadians to use for public security and fighting terrorism. The money allocated through the Public Security and Anti-Terrorism Initiative was intended to pay for measures designed to keep terrorists out of Canada, to prosecute those found in the country, to support international initiatives, and to protect infrastructure.
But Auditor-General Michael Ferguson said only $9.8-billion of that money was identified in reports to the Treasury Board as having been spent specifically on anti-terrorism measures by the departments and agencies. The rest was not recorded as being used for that purpose. Some was moved to other priorities, and some lapsed without being spent, but the government has no full breakdown for the $3.1-billion.
The time period 2001 – 2009 implicates both Liberal and Conservative governments, the Conservatives having come to power in 2006.
About Bob Sandford and EPCOR
One final note, the report’s co-lead author, Bob Sandford, is described as the chair for EPCOR Canadian Partnership Initiative in support of the UN Water for Life Decade, It’s a rather interesting title in that Sandford is not on the EPCOR board. Here’s how EPCOR describes Sandford on the company’s webpage dedicated to him and dated March 13, 2013,
Robert Sandford is the EPCOR Chair in support of the United Nations “Water for Life” Decade of Action initiative in Canada. We support his efforts as he speaks in plain language to policy makers, explaining how his work links research and analysis to public policy ideas that help protect water supplies and reduce water consumption.
We’re proud to sponsor his leadership efforts to educate Canadians and help local and international governments become better stewards of a most precious resource. Supporting Robert is just one of the ways EPCOR works to protect water in our communities.
The company which is owned solely by the city of Edmonton (Alberta) was originally named Edmonton Electric Lighting and Power Company in 1891. As they say on the company’s About page, “We provide electricity and water services to customers in Canada and the US.” They also develop some nice public relations strategies. I’m referring, of course, to the Sandford sponsorship which can be better appreciated by going to Sandford’s, from the homepage,
Bob Sandford is the EPCOR Chair of the Canadian Partnership Initiative in support of United Nations “Water for Life” Decade. This national partnership initiative aims to inform the public on water issues and translate scientific research outcomes into language decision-makers can use to craft timely and meaningful public policy.
Bob is also the Director of the Western Watersheds Research Collaborative and an associate of the Centre for Hydrology which is part of the Global Water Institute at the University of Saskatchewan. Bob is also a Fellow of the Biogeoscience Institute at the University of Calgary. He sits on the Advisory Board of Living Lakes Canada, the Canadian Chapter of Living Lakes International and is also a member of the Forum for Leadership on Water (FLOW), a national water policy research group centred in Toronto. Bob also serves as Water Governance Adviser and Senior Policy Author for Simon Fraser University’s Adaptation to Climate Change Team. In 2011, Bob was invited to be an advisor on water issues by the Interaction Council, a global public policy forum composed of more than thirty former Heads of State including Canadian Prime Minister Jean Chretien, U.S. President Bill Clinton, and the former Prime Minister of Norway, Gro Brundtland. In this capacity Bob works to bring broad international example to bear on Canadian water issues. In 2013, Alberta Ventures magazine recognized Bob as one of the year’s 50 most influential Albertans.
The February 2015 issue of Industrial Biotechnology is hosting a special in depth research section on the topic of cellulose nanotechnology. A Feb. 19, 2015 news item on Phys.org features a specific article in the special section (Note: A link has been removed),
Novel nanomaterials derived from cellulose have many promising industrial applications, are biobased and biodegradable, and can be produced at relatively low cost. Their potential toxicity—whether ingested, inhaled, on contact with the skin, or on exposure to cells within the body—is a topic of intense discussion, and the latest evidence and insights on cellulose nanocrystal toxicity are presented in a Review article in Industrial Biotechnology.
Maren Roman, PhD, Virginia Tech, Blacksburg, VA, describes the preparation of cellulose nanocrystals (CNCs) and highlights the key factors that are an essential part of studies to assess the potential adverse health effects of CNCs by various types of exposure. In the article “Toxicity of Cellulose Nanocrystals: A Review” , Dr. Roman discusses the current literature on the pulmonary, oral, dermal, and cytotoxicity of CNCs, provides an in-depth view on their effects on human health, and suggests areas for future research.
There has been much Canadian investment both federal and provincial in cellulose nanocrystals (CNC). There’s also been a fair degree of confusion regarding the name. In Canada, which was a research leader initially, it was called nanocrystalline cellulose (NCC) but over time a new term was coined cellulose nanocrystals (CNC). The new name was more in keeping with the naming conventions for other nanoscale cellulose materials such as cellulose nanofibrils, etc. Hopefully, this confusion will resolve itself now that Celluforce, a Canadian company, has trademarked NCC. (More about Celluforce later in this post.)
Getting back to toxicity and CNC, here’s a link to and a citation for Maron’s research paper,
The article is open access at this time. For anyone who doesn’t have the time to read it, here’s the conclusion,
Current studies of the oral and dermal toxicity of CNCs have shown a lack of adverse health effects. The available studies, however, are still very limited in number (two oral toxicity studies and three dermal toxicity studies) and in the variety of tested CNC materials (CelluForce’s NCC). Additional oral and dermal toxicity studies are needed to support the general conclusion that CNCs are nontoxic upon ingestion or contact with the skin. Studies of pulmonary and cytotoxicity, on the other hand, have yielded discordant results. The questions of whether CNCs have adverse health effects on inhalation and whether they elicit inflammatory or oxidative stress responses at the cellular level therefore warrant further investigation. The toxicity of CNCs will depend strongly on their physicochemical properties—in particular, surface chemistry, including particle charge, and degree of aggregation, which determines particle shape and dimensions. Therefore, these properties—which in turn depend strongly on the cellulose source, CNC preparation procedure, and post-processing or sample preparation methods, such as lyophilization, aerosolization, sonication, or sterilization—need to be carefully measured in the final samples.
Another factor that might affect the outcomes of toxicity studies are sample contaminants, such as endotoxins or toxic chemical impurities. Samples for exposure tests should therefore be carefully analyzed for such contaminants prior to testing. Ideally, because detection of toxic chemical contaminants may be difficult, control experiments should be carried out with suitable blanks from which the CNCs have been removed, for example by membrane filtration. Moreover, especially in cytotoxicity assessments, the effect of CNCs on pH and their aggregation in the cell culture medium need to be monitored. Only by careful particle characterization and exclusion of interfering factors will we be able to develop a detailed understanding of the potential adverse health effects of CNCs.
If I understand this rightly, CNC seems safe (more or less) when ingested orally (food/drink) or applied to the skin (dermal application) but inhalation seems problematic and there are indications that this could lead to inflammation of lung cells. Other conclusions suggest both the source for the cellulose and CNC preparation may affect its toxicity. I encourage you to read the whole research paper as this author provides good explanations of the terms and summaries of previous research, as well as, some very well considered research.
The article is part of an IB IN DEPTH special research section entitled “Cellulose Nanotechnology: Fundamentals and Applications,” led by Guest Editors Jose Moran-Mirabal, PhD and Emily Cranston, PhD, McMaster University, Hamilton, Canada. In addition to the Review article by Dr. Roman, the issue includes Reviews by M. Rose, M. Babi, and J. Moran-Mirabal (“The Study of Cellulose Structure and Depolymerization Through Single-Molecule Methods”) and by X.F. Zhao and W.T. Winter (“Cellulose/cellulose-based nanospheres: Perspectives and prospective”); Original Research articles by A. Rivkin, T. Abitbol, Y. Nevo, et al. (“Bionanocomposite films from resilin-CBD bound to cellulose nanocrystals), and P. Criado, C. Fraschini, S. Salmieri, et al. (“Evaluation of antioxidant cellulose nanocrystals and applications in gellan gum films”); and the Overview article “Cellulose Nanotechnology on the Rise,” by Drs. Moran-Mirabal and Cranston.
Meanwhile Celluforce announces a $4M ‘contribution’ from Sustainable Development Technology Canada (SDTC), from a Feb. 16, 2015 Celluforce news release,
CelluForce welcomes the announcement by Sustainable Development Technology Canada (SDTC) of a contribution of $4.0 million to optimize the extraction process of Nanocrystaline Cellulose (NCC) from dry wood pulp and develop applications for its use in the oil and gas sector. The announcement was made in Quebec City today [Feb. 16, 2015] by the Honourable Greg Rickford, Minister of Natural Resources and Minister for the Federal Economic Development Initiative for Northern Ontario.
NCC is a fundamental building block of trees that can be extracted from the forest biomass and has unique properties that offer a wide range of potential applications. Measured in units as small as nanometres, these tiny structures have strength properties comparable to steel and will have uses in a variety of industrial sectors. In particular, NCC is touted as having the potential to significantly advance the oil and gas industry.
“Our Government is positioning Canada as a global leader in the clean technology sector by supporting innovative projects aimed at growing our economy while contributing to a cleaner environment,” said the Honourable Greg Rickford, Canada’s Minister of Natural Resources. [emphasis mine] “By developing our resources responsibly, exploring next-generation transportation and advancing clean energy technology, the projects announced today will create jobs and improve innovation opportunities in Quebec and across Canada.”
“World-class research led to the development of this ground breaking extraction process and placed Canada at the leading edge of NCC research”, stated René Goguen, Acting President of CelluForce Inc. “This announcement by SDTC sets the stage for the pre-commercial development of applications that will not only support Canada’s forest sector but also the oil and gas sector, both of which are important drivers of the Canadian economy.”
This project will further improve and optimize the process developed by CelluForce to extract nanocrystalline cellulose (CelluForce NCC™) from dry wood pulp. In addition to improving the extraction process, this project will investigate additional applications for the oil-and-gas industry such as cementing using this renewable forestry resource.
There’s very little information in this news release other than the fact that CelluForce’s $4M doesn’t need to be repaid seeing it’s described as a ‘contribution’ rather than an investment. The difference between a contribution and a grant, which is what these funds used to be called, somewhat mystifies me unless this is a translation issue.
As for the news release content, it is remarkably scant. This $4M will be spent on improving the extraction process and on applications for the oil and gas industry. Neither the improvements nor the possible applications are described. Hopefully, the government has some means of establishing whether or not those funds (sorry, the contribution) were used for the purposes described.
I am glad to see this in this news release, “Our Government is positioning Canada as a global leader in the clean technology sector …” although I’m not sure how it fits with recent attempts to brand environmentalists as part of an ‘anti-petroleum’ movement as described in a Feb. 19, 2015 post by Glyn Moody for Techdirt (Note: A link has been removed),
As Techdirt has been warning for some time, one of the dangers with the flood of “anti-terrorist” laws and powers is that they are easily redirected against other groups for very different purposes. A story in the Globe and Mail provides another chilling reminder of how that works:
The RCMP [Royal Canadian Mounted Police] has labelled the “anti-petroleum” movement as a growing and violent threat to Canada’s security, raising fears among environmentalists that they face increased surveillance, and possibly worse, under the Harper government’s new terrorism legislation.
As the Globe and Mail article makes clear, environmentalists are now being considered as part of an “anti-petroleum” movement. That’s not just some irrelevant rebranding: it means that new legislation supposedly targeting “terrorism” can be applied.
…
It seems logically incoherent to me that the government wants clean tech while condemning environmentalists. Whether or not you buy climate change science (for the record, I do), you have to admit that we are running out of petroleum. At heart, both the government and the environmentalists have to agree that we need new sources for fuel. It doesn’t make any sense to spend valuable money, time, and resources on pursuing environmentalists.
This business about the ‘anti-petroleum’ movement reminds me of a copyright kerfuffle including James Moore, currently the Minister of Industry, and writer Cory Doctorow. Moore, Minister of Canadian Heritage at the time, at some sort of public event, labeled Doctorow as a ‘radical extremist’ regarding his (Doctorow’s) views on copyright. The comments achieved notoriety when it appeared that Moore and the organizers denied the comments ever took place. The organizers seemed to have edited the offending video and Moore made public denials. You can read more about the incident in my June 25, 2010 post. Here’s an excerpt from the post which may explain why I feel there is a similarity,
… By simultaneously linking individuals who use violence to achieve their ends (the usual application for the term ‘radical extremists’) to individuals who are debating, discussing, and writing commentaries critical of your political aims you render the term into a joke and you minimize the violence associated with it.
Although with ‘anti-petroleum’, it seems they could decide any dissension is a form of violence. It should be noted that in Canada the Ministry of Industry, is tightly coupled with the Ministry of Natural Resources since the Canadian economy has been and continues to be largely resource-based.
For anyone interested in CelluForce and NCC/CNC, here’s a sampling of my previous posts on the topic,
There’s a lot more about CNC on this blog* should you care to search. One final note, I gather there’s a new interim boss at CelluForce, René Goguen replacing Jean Moreau.

A July 7, 2014 news item on Azonano features a new technique that could help doctors better diagnose problems in the intestines (guts),
Located deep in the human gut, the small intestine is not easy to examine. X-rays, MRIs and ultrasound images provide snapshots but each suffers limitations. Help is on the way.
University at Buffalo [State University of New York] researchers are developing a new imaging technique involving nanoparticles suspended in liquid to form “nanojuice” that patients would drink. Upon reaching the small intestine, doctors would strike the nanoparticles with a harmless laser light, providing an unparalleled, non-invasive, real-time view of the organ.
“Conventional imaging methods show the organ and blockages, but this method allows you to see how the small intestine operates in real time,” said corresponding author Jonathan Lovell, PhD, UB assistant professor of biomedical engineering. “Better imaging will improve our understanding of these diseases and allow doctors to more effectively care for people suffering from them.”
The average human small intestine is roughly 23 feet long and 1 inch thick. Sandwiched between the stomach and large intestine, it is where much of the digestion and absorption of food takes place. It is also where symptoms of irritable bowel syndrome, celiac disease, Crohn’s disease and other gastrointestinal illnesses occur.
To assess the organ, doctors typically require patients to drink a thick, chalky liquid called barium. Doctors then use X-rays, magnetic resonance imaging and ultrasounds to assess the organ, but these techniques are limited with respect to safety, accessibility and lack of adequate contrast, respectively.
Also, none are highly effective at providing real-time imaging of movement such as peristalsis, which is the contraction of muscles that propels food through the small intestine. Dysfunction of these movements may be linked to the previously mentioned illnesses, as well as side effects of thyroid disorders, diabetes and Parkinson’s disease.
The news release goes on to describe how the researchers manipulated dyes that are usually unsuitable for the purpose of imaging an organ in the body,
Lovell and a team of researchers worked with a family of dyes called naphthalcyanines. These small molecules absorb large portions of light in the near-infrared spectrum, which is the ideal range for biological contrast agents.
They are unsuitable for the human body, however, because they don’t disperse in liquid and they can be absorbed from the intestine into the blood stream.
To address these problems, the researchers formed nanoparticles called “nanonaps” that contain the colorful dye molecules and added the abilities to disperse in liquid and move safely through the intestine.
In laboratory experiments performed with mice, the researchers administered the nanojuice orally. They then used photoacoustic tomography (PAT), which is pulsed laser lights that generate pressure waves that, when measured, provide a real-time and more nuanced view of the small intestine.
The researchers plan to continue to refine the technique for human trials, and move into other areas of the gastrointestinal tract.
Here’s an image of the nanojuice in the guts of a mouse,

This is an international collaboration both from a research perspective and a funding perspective (from the news release),
Additional authors of the study come from UB’s Department of Chemical and Biological Engineering, Pohang University of Science and Technology in Korea, Roswell Park Cancer Institute in Buffalo, the University of Wisconsin-Madison, and McMaster University in Canada.
The research was supported by grants from the National Institutes of Health, the Department of Defense and the Korean Ministry of Science, ICT and Future Planning.

Glass, as many folks know, has a dual nature, being simultaneously both liquid and solid, making truly accurate measurement a bit of a challenge. A March 3, 2014 news item on Azonano notes that scientists at Canada’s Waterloo University have solved the surface measurement problems with glass,
University of Waterloo physicists have succeeded in measuring how the surfaces of glassy materials flow like a liquid, even when they should be solid.
…
Understanding the mobility of glassy surfaces has implications for the design and manufacture of thin-film coatings and also sets practical limits on how small we can make nanoscale devices and circuitry.
The work is the culmination of a project carried out by a research team led by Professor James Forrest and doctoral student Yu Chai from the University of Waterloo as well as researchers from École Superieure de Physique et de Chimie Industrielles in France and McMaster University [Canada].
“Common sense would tell you that if a material is solid, it’s solid everywhere. But we’ve shown that a solid isn’t a solid everywhere,” says James Forrest, a professor in Waterloo’s Department of Physics and Astronomy. “It’s almost solid everywhere – except a few nanometers at the surface.”
A series of simple and elegant experiments were the solution to a problem that has been plaguing condensed matter physicists for the past 20 years. The experiments revealed that at a certain temperature range, solid glassy materials actually have a very thin liquid-like layer at the surface.
…
Glass is much more than the material in bottles and windows. In fact, any solid without an ordered, crystalline structure is considered a glassy material, so metals, small molecules, and polymers can all be made into glassy materials.
Polymers, the building block of all plastics, are almost always glassy rather than crystalline. These materials undergo a transition between a brittle solid and a molten liquid in a narrow temperature range, which encompasses the so-called glass transition temperature.
In a series of experiments, Forrest and colleagues started with very thin slices of polystyrene stacked to create tiny staircase-like steps about 100-nanometres high – less than 0.001 per cent the thickness of a human hair. They then measured these steps as they became shorter, wider and less defined over time.
The simple 2-dimensional profile of this surface step allowed the physicists to numerically model the changes to the surface’s geometry above and below the glass transition temperature.
Results show that above the transition temperature, polystyrene flows entirely like a liquid; but below this temperature the polymer becomes a solid with a thin liquid-like layer at the surface.
Forrest is also a University Research Chair, a member of the Waterloo Institute for Nanotechnology and an associate faculty member at the Perimeter Institute.
The project team also includes Kari Dalnoki-Veress and J.D. McGraw from McMaster University and Thomas Salez, Michael Benzaquen and Elie Raphael of the École Superieure de Physique et de Chimie Industrielles in Paris.
The researchers have provided a 21 second animation to illustrate their work,

Imaginative: 83 Bold Innovations to Improve Global Health Receive Grand Challenges Canada Funding
Among novel ideas to reduce disease, save lives in developing world:
Diagnostic diapers to detect deadly rotavirus; Rolling water barrel;
Special yogurt offsets pesticides, heavy metals, toxins in food;
Inventive shoe, boot material releases bug repellent when walking
50 innovators from low- and middle-income countries, plus 33 from Canada, share $9.3 million in seed grants
Grand Challenges Canada, funded by the Government of Canada, today extends seed grants of $100,000 each to 83 inventive new ideas for addressing health problems in resource-poor countries.
The Grand Challenges Canada “Stars in Global Health” program seeks breakthrough and affordable innovations that could transform the way disease is treated in the developing world — innovations that may benefit the health of developed world citizens as well.
Of the 83 grants announced today, 50 are given to innovators in 15 low- and middle-income nations worldwide and 33 to Canadian-originated projects, to be implemented in a total of 30 countries throughout the developing world.
“Innovation powers development leading to better health and more jobs. I feel proud that Canada, through Grand Challenges Canada, has supported almost 300 bold ideas to date in our Stars in Global Health program,” says Dr. Peter A. Singer, Chief Executive Officer of Grand Challenges Canada. “This is one of the largest pipelines of innovations in global health in the world today.”
Says the Honourable Christian Paradis, Canadian Minister of International Development and Minister for La Francophonie: “Grand Challenges Canada’s portfolio of projects shows how innovators with bold ideas have the potential to make a big impact on global health. By connecting game-changing ideas with some of the most pressing global health challenges, these projects will lead to sustainable and affordable health solutions in low- and middle-income countries.”
The portfolio of 83 creative, out-of-the-box ideas, selected through independent peer review from 451 applications, includes projects submitted by social entrepreneurs, private sector companies and non-government organizations as well as university researchers. Among them:
Diagnostics
…
A simple, portable, dry, yeast-based blood screening test (Belize, Jamaica). WHO estimates almost half of 46 million blood donations in low-income countries are inadequately tested; in Africa up to 10% of new HIV infections are caused by transfusions. A University of Toronto-developed yeast-based blood screening tool will detect combinations of diseases. Like baking yeast, it can be stored dry, and can be grown locally with minimal equipment and training, improving accessibility in rural areas.
A bedside, Litmus paper-like test to detect bronchitis (Brazil, India). Being pioneered at McMaster University with international collaborators, a simple sputum test will detect infectious and allergic bronchitis in adults and children, reducing mis-diagnosis in developing countries and saving resources: time, steroids, antibiotics.
…
…
Water, sanitation, hygiene and general health
Special yogurts formulated to offset the harm to health caused by heavy metals, pesticides and other toxics in food (Africa). Between 2006-2009 in Nairobi, only 17% of the total maize sampled and 5% of feed was fit for human and animal consumption respectively. University of Western Ontario researchers have developed novel yogurts containing a bacteria that, in the stomach, sequesters certain toxins and heavy metals and degrades some pesticides.
…
Addressing arsenic-laced groundwater. In Bangladesh, 1 in 5 deaths (600,000 per year) occur due to groundwater arsenic, dubbed by WHO as the largest mass poisoning in history, with some 77 million people at risk. Project 1) Toronto-based PurifAid will deploy new filtration units via franchised villagers who will filter and deliver purified water, perform maintenance, acquire new filters and dispose of old ones, which can be used to produce biofuels. Project 2) A project based at the University of Calgary, meanwhile, will work to increase the use of Western Canadian lentils in Bangladeshi diets. The crop is rich in selenium, which can decrease arsenic levels and improve health.
“WaterWheel” (India, Kenya, Mongolia). This simple, innovative device from India is a wheeled water container that enables the collection and transport of 3 to 5 times as much water as usual per trip, as well as hygienic storage, saving valuable time for productive activities and improving health.
Malaria
A vaccine based on a newly-discovered antibody in men that prevents malaria infection in the placenta (Benin, Colombia). Colombian men exposed to malaria are found to have antibodies that can prevent infection in the placenta of a pregnant woman. This University of Alberta finding forms the basis for developing a novel vaccine against several forms of malaria, which cause 10,000 maternal deaths and 200,000 stillbirths annually.
Insect-repellent clothing, footwear and wall plaster (East Africa). 1) In Tanzania, the Africa Technical Research Institute will lead the design and manufacture of attractive, affordable insecticide-treated clothing while 2) the Ifakara Health Institute will develop anti-mosquito footwear material that slowly releases repellents from the friction of walking. A key advantage: no compliance or change in habits required. 3) Uganda’s Med Biotech Laboratories, meanwhile, will produce a colorful, insecticide-infused ‘plaster’ for the outside walls of African village homes.
Maternal and child health
…
Mothers Telling Mothers: improving maternal health through storytelling (Uganda). Work by Twezimbe Development Association has found that stories told by mothers in their own words and reflecting shared realities are most likely to increase the number of moms seeking skilled health care, and convince policymakers to improve healthcare access. This project will capture 3 to 5 minutes stories to be shared through digital media platforms and health clinics.
…
Mobile technology
Digital African Health Library (Sub-Saharan Africa). The University of Calgary-led project is creating an app to support bedside care by medical doctors in Africa: a smartphone-accessible resource providing evidence-based, locally-relevant decision support and health information. A pilot involving 65 doctors in Rwanda showed point of care answers to patient questions more than tripled to 43%, with self-reported improvement in patient outcomes.
Health care
Simple sticker helps track clean surfaces in healthcare facilities (Philippines). WHO estimates that 10% to 30% of all patients in developing country health care facilities acquire an infection. An innovative sticker for hospital surfaces developed by Lunanos Inc. changes colour when a cleaner is applied and fades color after a predetermined period of time, helping staff track and ensure cleanliness of equipment and other frequently touched surfaces.
“Mystery clients” to assess and improve quality of TB care (India). India accounts for 25% of global tuberculosis (TB) incidence. To evaluate variations in practice quality, and identify ways to improve TB management in India, this project, led by Canada’s McGill University, will send researchers into clinics posing as a patient with standard TB symptoms. The project builds on earlier work related to angina, asthma and dysentery, which revealed incorrect diagnoses and treatment.
And many more.
A complete set of 83 short project descriptions, with links to additional project details, available photos / video, and local contact information, is available in the full news release online here: http://bit.ly/HOLt5b
Here’s a video for the one of the projects (filtering arsenic out of Bangladesh’s water),
I chose this project somewhat haphazardly. It caught my attention as I have written more than once about purification efforts and as it turns out, this is a Canada-based project (with a Bangladeshi partner, BRAC) from the University of Toronto.
We plan to roll out a new generation of filtration units which run on an organic by-product of the beverage industry. The units address many of the failings of existing devices (they require no power or chemicals and are very low maintenance).
This project gets still more interesting (from the full project description page),
Device for the Remediation and Attenuation of Multiple Pollutants (DRAM) removes 95% of arsenic from contaminated water within 5 minutes of exposure. With an estimated 600,000 deaths directly attributable to arsenic poisoning every year, these units hold the potential to save millions of lives. Existing solutions are too complicated and suffer from significant usability issues (2012 UNICEF study).
We will deploy our units through a franchise business model. [emphasis mine] Local villagers will filter and deliver purified water, perform maintenance, acquire new media, and dispose spent media. The current market leader, the Sono Filter, has less than 20% uptake (according to UNICEF). DRAM costs only 25% of this solution, has lower maintenance requirements (4-6 month media cycle vs. 2 week media cycle), higher durability, and can be retrofitted onto existing tube wells villagers use thereby requiring no behavior change. The spent media (which must be replaced every 4-6 months) can be used to produce biofuels, giving PurifAid a decisive capability over competitors.
With the assistance of our local partner BRAC (ranked #1 on Global Journal’s list of top NGOs in 2012) we will retrofit our units onto existing tubewells. Contaminated water is pumped from the tubewell into the unit where it passes into the bottom of the unit, rising up through a bed of the organic filter media, binding the arsenic. Clean water is displaced and forced out of the top of the unit and out through the built-in tap. Our community based solution will begin with a proof-of-concept installation in the Mujibnagar District (pop. 1.3 million). BRAC will assist in testing our filter water quality on the ground and these results will be used to obtain regulatory approval for our technology. We will then operationalize our community-run DRAM systems. A council of local stakeholders will nominate prospective franchisees amongst villagers. These villagers will replace filter media in 4 month intervals and order annual delivery of new media. We are securing partnerships with nearby distilleries to locally source the filter media. [emphasis mine] Disposal will be handled by a local caretaker who will store spent media in bulk before transferring it for use as biofuel. Caretaker salary, media sourcing, and delivery costs will be paid by charging a levy on customer households. PurifAid will monitor behavioural and health indicators to ascertain DRAM’s immediate and long-term impact. To this end PurifAid has partnered with Ashalytics, a start-up global health analytics company, to report operational issues, measure impact, and communicate important metrics to key staff and stakeholders via mobile phones. This results in an environmentally-friendly value chain that uses beverage industry waste, maximizing positive impact. If the Bangladesh installations are a success then this system can be introduced across the Indian subcontinent and in west Africa, where arsenic in groundwater poses a serious health problem. DRAM has the potential to improve the lives of millions globally.
After 18 months we envisage having installed 15 DRAM systems supplying 45 liters of purified water per day to 2,700 households. In order to ensure maintenance, 15 paid caretakers will operate the pumps and a driver will supply the caretakers with fresh media every 4-6 months. Biannually, new bulk media will be provided to storage unit in the village, spent media will in turn be taken to a plant and converted to biofuel. Villagers will invest collectively to purchase, install and operate DRAM on pre-existing tube wells – thus no behavioral changes needed.
Our filters employ a new water filtration technology. Our franchise model involves social and business innovation, empowering communities to manage their own water treatment under the stewardship of a local partner that manages 17 social businesses with combined annual revenues of $93m in 2011.
(Aside: Don’t they ask for a ‘dram’ of whiskey in the movies?) This project is intended to do more than purify water; it’s designed to create jobs. Bravo!

About Canada’s International Development Research Centre
The International Development Research Centre (IDRC) supports research in developing countries to promote growth and development. IDRC also encourages sharing this knowledge with policymakers, other researchers and communities around the world. The result is innovative, lasting local solutions that aim to bring choice and change to those who need it most. As the Government of Canada’s lead on the Development Innovation Fund, IDRC draws on decades of experience managing publicly funded research projects to administer the Development Innovation Fund. IDRC also ensures that developing country researchers and concerns are front and centre in this exciting new initiative.
The Canadian Institutes of Health Research (CIHR) is the Government of Canada’s health research investment agency. CIHR’s mission is to create new scientific knowledge and to enable its translation into improved health, more effective health services and products, and a strengthened Canadian health care system. Composed of 13 Institutes, CIHR provides leadership and support to more than 14,100 health researchers and trainees across Canada. CIHR will be responsible for the administration of international peer review, according to international standards of excellence. The results of CIHR-led peer reviews will guide the awarding of grants by Grand Challenges Canada from the Development Innovation Fund.

I have found it confusing that there’s a Grand Challenges Canada and the Bill and Melinda Gates Foundation has a Grand Challenges programme, both of which making funding announcements at this time of year. I did make some further investigations which I noted in my Dec. 22, 2011 posting,
Last week, the Bill & Melinda Gates Foundation announced a $21.1 M grant over three years for research into point-of-care diagnostic tools for developing nations. A Canadian nongovermental organization (NGO) will be supplementing this amount with $10.8 M for a total of $31.9 M. (source: Dec. 16, 2011 AFP news item [Agence France-Presse] on MedicalXpress.com)
At this point, things get a little confusing. The Bill & Melinda Gates Foundation has a specific program called Grand Challenges in Global Health and this grant is part of that program. Plus, the Canadian NGO is called Grand Challenges Canada (couldn’t they have found a more distinctive name?), which is funded by a federal Canadian government initiative known as the Development Innovation Fund (DIF). …
Weirdly, no one consulted with me when they named the Bil & Melinda Gates Foundation programme or the Canadian NGO.
The Feb. 24, 2012 news item on Nanowerk offers an update on the solar cell project being undertaken by McMaster University (Ontario, Canada), Zhejiang University (China), Hyperion Shanghai Drive Technology Co. Ltd., and Cleanfield Energy (Ontario, Canada). From the news item,
[The four partners] were recently awarded an International Science and Technology Partnerships Program (ISTPP) grant, with an objective to further develop a new photovoltaic (PV) nanowire solar cell based on low cost substrates initially intended for the rapidly expanding concentrator photovoltaic (CPV) market.
The ISTPP funds will be used to develop a semiconductor nanowire, which will improve the efficiency and reduce fabrication costs of PV cells due to light trapping, enhanced carrier extraction, and the ability to use inexpensive substrates. This project will draw on the existing strengths of McMaster University in the fabrication of III-V compound semiconductor nanowires to advance the state-of-the-art PV and the Zhejiang University group, which have expertise in optoelectronic devices including electrode deposition and optical characterization of materials and devices.
For anyone who’s interested, here’s a description of the Canadian government’s International Science and Technology Partnerships Program (ISTPP), from their home page,
The International Science & Technology Partnerships Program (ISTPP) was announced by the Government of Canada in June 2005, to promote international collaborative research and development activities. The five-year, $20-million program will increase the international competitiveness and prosperity of Canada by building stronger science and technology relationships with Israel, India, China and Brazil. [emphasis mine]
The ISTPP will foster and support bilateral research projects which have the potential for commercialization between Canada and identified partner countries. It will also stimulate bilateral science and technology networking and matchmaking activities to further new partnerships and accelerate the commercialization of research and development. The ISTPP is a “seed fund”, meaning that various other public and private sector participants are also encouraged to bring S&T expertise and funds of their own to the bilateral relationship.
I see there’s no mention of Russia or South Africa, two members of a loose consortium of countries called the BRICS (Brazil, Russia, India, China, and South Africa).
Here are a few more technical details about the nanowires and solar cells from the news item,
The cost of PV devices can be reduced by replacing the single crystal substrates with thin film technology. However, the poly-crystalline nature of these thin film technologies generally results in reduced PV efficiency. To overcome these limitations, a substantial body of recent work in PV is beginning to exploit intentionally engineered nano-scale structures and the physics of reduced dimensionality to increase device performance. One of the leading contenders in the area of nanotechnology-based PV devices is semiconductor nanowires. .. Nanowires are easily grown using the well-known vapour-liquid-solid (VLS) process. The rapid growth rate (up to 10 microns per hour) and lower material utilization of nanowires compared to thin film PV devices implies lower fabrication costs. In addition, nanowires can be grown on less expensive substrates as compared to the expensive germanium substrates used in current concentrator PV cells.
The partners are hoping this project will lead to greater adoption of solar cells that are cheaper while maintaining their efficiency.
