A closer look at the interface between water and solid surfaces sparks memories of the water/air interface

Leave a reply

Researchers at China’s Peking University have developed a technique for taking the closest look possible at the interface  between water and solid surfaces according to a Jan. 10, 2014 news item on Nanowerk,

The interaction of water with the surfaces of solid materials is ubiquitous. Many remarkable physical and chemical properties of water/solid interfaces are governed by H-bonding interaction between water molecules. As a result, the accurate description of H-bonding configuration and directionality is one of the most important fundamental issues in water science. Ideally, attacking this problem requires the access to the internal degrees of freedom of water molecules, i.e. the O-H directionality. However, resolving the internal structure of water has not been possible so far despite massive efforts in the last decades due to the light mass and small size of hydrogen.

Recently, the teams led by Professor Ying Jiang and Professor Enge Wang of International Center for Quantum Materials (ICQM) of Peking University succeeded to achieve submolecular-resolution imaging of individual water monomers and tetramers adsorbed on a Au [gold]-supported NaCl [sodium chloride](001) film at 5 K, using a cryogenic scanning tunneling microscope (STM).

The Jan. 9, 2014 University of Peking news release, which originated the news item, provides more detail,

… They first decoupled electronically the water molecule from the metal substrate by inserting an insulating NaCl layer and then employed the STM tip as a top gate to tune controllably the molecular density of states of water around the Fermi level. These key steps enabled them to image the frontier molecular orbitals which are spatially locked together with the geometric structures of water molecules. Notably, they were able to discriminate in real space the orientation of water monomers and the H-bonding directionality of water tetramers based on the submolecular-resolution orbital images.

This work opens up the possibility of determining the detailed topology of H-bonded networks at water/solid interfaces with atomic precision, which is only possible through theoretical simulations in the past. The ability to resolve the O-H directionality of water provides further opportunities for probing the dynamics of H-bonded networks at atomic scale such as H-atom transfer and bond rearrangement. In addition, the novel orbital-imaging technique developed in this work reveals new understanding of STM experiments and may be applicable to a broad range of molecular systems and materials.

As noted in the headline, this work sparked a memory of research conducted on the water/air interface and the discovery that the boundary between water and air is not as distinct as was believed. (I have a longstanding interest in boundaries, which often have an arbitrary nature.) From the 2011 (?) news item on Softpedia,

The question of where water stops and where air begins is a very old, and difficult-to-answer one. Experts have been trying to do so for years, and now it would appear that they finally have an answer. The layer separating the two is as thin as the distance between two atoms in a hydrogen molecules.

At the topmost layer of water, in an ocean for example, water (H2O) molecules are having a real problem – they cannot really decided whether to exist as gas or liquid. As such, one of the two hydrogen atoms remains in the water, while the second ones pokes out into the air.

Physicists now call this the layer of molecular ambiguity, and say that it has little to no effect on the way water below this level behaves. …

Interestingly, just one molecule beneath this first layer of H2O molecules, the rest of the water behaves as if nothing is going on in the layers above. This discovery is critically important for many fields of research, including for example atmospheric chemistry.

“In some ways this is a negative result. Sometimes a negative result can be very positive,” says Pavel Jungwirth, a scientist at the Academy of Sciences of the Czech Republic, in Prague. …

…

With the new data, says University of Victoria [located in British Columbia, Canada] physical chemist Dennis Hore, scientists will be able to refine models seeking to explain how water interacts with other chemicals within living cells. …

University of Victoria’s (Canada) microscope, world’s most powerful, unveiled

Leave a reply

This new microscope at the University of Victoria (UVic) was supposed to be unveiled in 2011 according to my July 28, 2009 posting about the purchase,

In other BC news, the University of Victoria (Canada) will be getting a new microscope which senses at subatomic levels. (From the media release on Azonano),

The new microscope-called a Scanning Transmission Electron Holography Microscope (STEHM) — will use an electron beam and holography techniques to observe the inside of materials and their surfaces to an expected resolution as small as one-fiftieth the size of an atom.

This is being done in collaboration with Hitachi High-Technologies which is building the microscope in Japan and installing it at U Vic in late 2010. The microscope will be located in a specially adapted room where work to prepare and calibrate it will continue until it becomes operational sometime in 2011.

I had been wondering if I’d ever hear of the microscope again, so finding a June 18, 2013 news item on Nanowerk announcing the world’s most powerful microscope at the University of Victoria (British Columbia, Canada) answered the question for me (Note: A link has been removed),

The world’s most powerful microscope, which resides in a specially constructed room at the University of Victoria, has now been fully assembled and tested, and has a lineup of scientists and businesses eager to use it.

The seven-tonne, 4.5-metre tall Scanning Transmission Electron Holography Microscope (STEHM), the first such microscope of its type in the world, came to the university in parts last year,. A team from Hitachi, which constructed the ultra high-resolution, ultra-stable instrument, spent one year painstakingly assembling the STEHM in a carefully controlled lab in the basement of the Bob Wright Centre.

The wait was worth it, says Rodney Herring, a professor of mechanical engineering and director of UVic’s Advanced Microscopy Facility. [emphasis mine]

The June 17, 2013 University of Victoria news release, which originated the news item, doesn’t address the two year delay directly as Herring’s quote seems to be in reference to the one-year assembly period. The news release goes on to describe the microscope’s resolution,

Herring viewed gold atoms through the microscope at a resolution of 35 picometres. One picometre is a trillionth of a metre. This resolution is much better than the previous best image with 49-picometre resolution taken at the Lawrence Berkley National Laboratory in California, and is about 20 million times human sight.

The STEHM allows researchers to see the atoms in a manner never before possible. It has full analytical capabilities that can determine the types and number or elements present, and high-resolution cameras for collecting data.

It will be used by researchers of many science and engineering disciplines for projects requiring knowledge of small atomic scale structures (nanoscience) and nanotechnology. Dr. Vincenzo Grillo from the Istituto Nanoscienze Consiglio Nazionale Delle Ricerche in Modena [Italy] will be the first visiting researcher later this month.

A line-up seems to have formed (from the news release),

Local scientists and businesses are also eager to use it. Ned Djilali, a UVic professor of mechanical engineering, is working with the National Research Council, Ballard Power Systems in Vancouver and Mercedes-Benz on fuel cell research. The STEHM “opens up entirely new possibilities” in fuel cell technology, says Djilali.

Redlen Technologies, a local company that manufactures high resolution semiconductor radiation detectors that are used for such things as nuclear cardiology, CT scanning, baggage scanning and dirty bomb detection, has been waiting for the STEHM to open for the company’s research and development.

If you are curious but don’t have any special influence, you can find out about the microscope (and perhaps view it?) later this week (from the news release),

Herring will give details of the results at a microscopy conference this week at UVic, as well as during a talk Thursday, June 20, that is open to the public. [emphasis mine] It is from 4:30 to 5 p.m. at the Bob Wright Centre, in Flury Hall, room B150.

I don’t usually include funding information but since I am from British Columbia, I have more of an interest than usual (from the news release),

The STEHM microscope is supported by $9.2 million in funding from the government of Canada through the Canadian Foundation for Innovation, the BC Knowledge Development Fund and UVic, as well as significant in-kind support from Hitachi.

Since microscopes and big equipment (in general) are weirdly fascinating to me, here are some details from UVic’s STEHM backgrounder,

The Scanning Transmission Electron Holography Microscope (STEHM) is the highest resolution microscope ever built and the only one of its kind in the world. It’s arrival makes the University of Victoria a global leader in the competitive field of advanced microscopy.

Unlike conventional microscopes, which use light to peer at specimens, the STEHM uses an electron beam and holography techniques to observe the inside of materials and their surfaces to an expected resolution smaller than the size of an atom.

The STEHM will see materials beyond the nanoscale to the picoscale. A nanometer is one-billionth of a metre, while a picometre is one-trillionth of a metre. Atoms are typically between 62 and 520 picometres in diameter.

…

The STEHM will not only see individual atoms, but it will indicate what type of atoms they are. It also features an electron vortex beam, which researchers can use like tweezers to manipulate individual atoms in a specimen.

The microscope itself is a 4.5-metre tall cylinder encased in metal shielding to block magnetic fields. It has a footprint of six square metres and weighs seven tonnes.

The microscope is so huge that researchers will climb a stepladder to insert their specimens through a tiny airlock into the vacuum of the column. They’ll then leave the room, wait for the air currents in the room to calm, and then operate the microscope remotely from an adjoining room.

The microscope is so sensitive that its image could be affected by little more than a passing cloud. …

I don’t know how many times the public will have any access to this microscope given its extreme sensitivity so you might want to make a point of attending the public talk on Thursday, June 20, 2013 at the University of Victoria.

One final comment, I find it a bit disconcerting that the only ‘academic’ research mentioned seems to be Italian and that the ‘Canadian’ research is primarily commercial. It’s very nice that Dr. Herring saw a gold nanoparticle but are there any local or Canadian publicly funded academic researchers using this microscope, which seems to have been paid for by taxpayers? Hopefully, this is a case where excitement took over and the writer who almost always focuses on local, academic research got carried away with the international involvement and big name companies (Mercedes Benz).

Canadian government withdraws from UN treaty, recycles old news, and undergoes a ‘muzzled’ science probe

Leave a reply

Every once in a while, there’s a slew of announcements that seem to reveal a pattern of sorts with regard to political doings. In this case, I’m looking at three announcements about recent moves by the  Canadian Conservative government and which seem, to me, curiously interlinked.

First there was the announcement (CBC Mar. 27, 2013 news item) that Canada is withdrawing from the United Nations Convention to Combat Desertification, in those Countries Experiencing Severe Drought and/or Desertification (to become the only country in the world not party to it) and its annual commitment of $350,000. The CBC Mar. 28, 2013 news item provided more detail,

Prime Minister Stephen Harper said less than one-fifth of the $350,000 Canada contributes to the UN Convention to Combat Desertification goes to programming.

“This particular organization spends less than 20 per cent — 18 per cent — of the funds that we send it are actually spent on programming, the rest goes to various bureaucratic measures.That’s not an effective way to spend taxpayers’ money,” Harper told MPs during question period Thursday.

…

The Canadian Press reported Wednesday [Mar. 27, 2013?] the UN secretariat that administers the program was unaware of Canada’s decision until contacted by its reporter.

A spokesperson for the Canadian International Development Agency (CIDA) [emphasis mine] told CBC News the head of the secretariat was informed of the decision on Monday [Mar. 25, 2013?], and written confirmation was delivered to the UN Secretary General’s office in New York the same day.

But a UN official in Bonn told CBC News that Canada notified the UN about its withdrawal “informally last week by telephone” and “this is not considered proper notification… or protocol.”

The proper protocol is to formally write to the UN Secretary General Ban Ki-moon in New York and formally provide a notice that Canada is withdrawing from the treaty.

Paul Heinbecker, a former Canadian ambassador to the UN and chief foreign policy advisor to Prime Minister Brian Mulroney, wrote an Apr. 1, 2013 essay for the Globe and Mail about some recent history between Canada and the UN, this latest withdrawal, and its implications (Note: A link has been removed),

Following the Harper government’s failure in 2010 to win a Canadian seat on the UN Security Council, its disregard of the UN gave way to disdain. Ottawa’s rare appearances at the UN have tended to stress what it regards as Canada’s uniquely “principled” foreign policy, bringing to mind U.S. Secretary of State Dean Acheson’s characterization of Canadian foreign policy in the fifties as “the stern voice of the daughter of God,” and cementing Canada’s long-standing reputation as global mother-in-law.

Because of the links between drought, land degradation, desertification and climate change, withdrawal from the Desertification Convention comes with potentially significant costs. …

Heinbecker develops this line of thought by noting that the withdrawal makes it seem that Canada does not care about climate change (let’s not forget the withdrawal from Kyoto protocol, the UN Convention on Climate Change, a UN initiative from which the Canadian Conservative government withdrew in 2011) and noting this,

Given that the government of Alberta as well as ministers and departments in Ottawa have been going to considerable effort and expense to argue in the U.S. that Canada does care, it is self-harming to hand America’s Keystone opponents a stick to beat the pipeline with.

Also, because the locus of most of the devastation arising from desertification is in Africa, walking away from a treaty whose creation was led by the Mulroney and Chrétien governments reinforces the impression that Ottawa no longer cares about Africa. It is an impression that this government also went to some trouble and expense to try to reverse. Further, because the worst destruction from desertification is happening in the Sahara region, abandoning the treaty sends a mixed signal about the security issues at stake in Mali and the Sahel, and about Canadian mining interests there as well.

Thankfully, Prime Minister Stephen Harper and the conservative government are ensuring that our annual $350,000 contribution, after 2014, will no be longer wasted on what they termed a ‘talkfest’. To combat this negative impression being made on the rest of the world, there’s been an announcement (Azonano Apr. 6, 2013 news item) recycling some old government news about monies for the second phase of the Canadian International Food Security Research Fund (CIFSRF),

 “The Harper Government is committed to increasing food security to those most in need as part of Canada’s effective international assistance through investing in scientific research and innovation,” said Parliamentary Secretary Brown [Lois Brown]. “Canadian universities, businesses, and NGOs [nongovernmental organizations]  have expertise that they can share with the world. Together, we can use innovation to put an end to global hunger.”

The Canadian International Food Security Research Fund is a joint initiative between the Canadian International Development Agency (CIDA) and the International Development Research Centre (IDRC). [emphases mine] It supports innovative research partnerships between Canadian and developing-country researchers to respond to immediate food needs while increasing access to quality, nutritious food over the long term. Phase 2 will focus on connecting promising research results to public and private sector organizations that can get them to end users on a larger scale.

“IDRC and CIDA have a long history of supporting Canada’s leadership in agricultural research and innovation for development,” said Jean Lebel, Acting President of IDRC. “CIFSRF demonstrates our mutual commitment to achieving sustainable results that put Canada’s considerable experience in agricultural and nutrition science to work globally to ensure farmers have access to new technologies and specialized expertise to keep pace with the growing demand for food.  Through CIFSRF, we are also expanding Canada’s scientific base and contributing to the country’s science and technology strategy.”

The Canadian International Food Security Research Fund, first launched in 2009, currently supports 19 projects, bringing together some of the best researchers from 11 Canadian and 26 developing-country organizations, as well as partners from scientific, private sector and civil society organizations, to develop innovative solutions to improve global food security.

The part where it got really interesting for me was the April 4, 2013 article by Rick Westhead for  star.com about the funds some of which are bound for the University of Guelph as per its Apr. 5, 2013 news release about the matter. Not to be too confusing but the following excerpt is from the April 4, 2013 Westhead article,

Manish Raizada, a University of Guelph agriculture professor, is changing lives in India, Nepal and Sri Lanka by showing farmers how to boost crop yields with weeding and planting techniques and by adding new crops.

Other Canadian researchers are bolstering Ethiopia’s agriculture sector, introducing farmers to rhizobia, a bacteria that naturally adds nitrogen to the soil and helped Saskatchewan, nearly a century ago, become a leading soybean exporter.

Then there are Canadian-led efforts in India that use nanotechnology to improve the lifespan of mangoes, efforts that should help improve livelihoods in a country where half of children under five are malnourished. [In fact, this an India, Sri Lanka, and Canada effort which I mentioned in a June 21, 2012 posting and again in a Nov. 1, 2012 posting.]

…

For instance, McGurk [Dr. Stephen McGurk, IDRC director of agriculture programmes] said one government-funded project is helping lengthen the shelf life of mangoes by as much as two weeks by introducing a nanoparticle-based coating that prevents them from ripening as fast.

“That way they’re attractive when they get to market, not looking like pulp,” McGurk said. “That science, once it has been tried in India can be equally applied to fruits here like plums or raspberries.”

Interestingly, McGurk gives this quote to Westhead,

“In no way would Canadian scientists in the agriculture sector say they are muzzled,” said Stephen McGurk, director of IDRC’s agriculture programs. [emphasis mine] “We’re engaged outside our borders and doing research now that’s valuable to Canadians but has to prove its salt somewhere else first.”

What makes McGurk an interesting spokesperson regarding ‘muzzles and Canadian scientists’ is that he  is an economist and a sinologist who prior to his latest appointment as IDRC director of agriculture programmes seems to have lived in Asia for the last 12 years and given this career description is likely from the US originally (from the Oct. 9, 2012 IDRC announcement of McGurk’s appointment),

Stephen McGurk is a Sinologist and economist who has spent more than two decades studying Asia’s rural development.Since 2006, he has been Director of IDRC’s Regional Office for South Asia and China in New Delhi (now the Asia Regional Office). From 2000 to 2006, he led IDRC’s office in Singapore.

Before joining IDRC, McGurk worked with the Ford Foundation in Beijing, where he was responsible for its economic security program in China. He has also taught at the University of California and worked with the World Bank on investments in China’s rural development. McGurk has a PhD from Stanford University’s [California] Food Research Institute.

I am curious as to how Dr. McGurk comes by his information about Canadian government agricultural scientists and their views on muzzles or lack thereof.

In looking at all of these bits of information, the desertification treaty withdrawal seems odd, almost as if it were designed to divert attention from something else the Conservative government is doing. Or, perhaps it’s an example of meanspirited shortsightedness something this government has been accused of before.

The recycled news item seems like it might not be as helpful as one would hope, although governments of all stripes are known to announce monies for projects that have been previously announced making it seem that a great deal more money is being dispersed than is the case. These announcements are always excellent for distraction but one would think the government would be eager to emphasize funding for projects in African countries rather than Asian countries given the conservatives’ current public relations problems in that region, as noted by Heinbecker.

As for McGurk’s quote about muzzles and agricultural scientists, while it does seem a bit ‘facey’ of him, he, at least, is not afraid to say something (although it’s not clear why he was asked about the muzzle since the news release was strictly about funding). For more about the ‘muzzles’,  there’s this excerpt from the Apr. 2, 2013 Canadian Press news item found at macleans.ca on campus,

Federal policies that restrict what government scientists can say publicly about their work are about to be put under the microscope.

Federal Information Commissioner Suzanne Legault has agreed to investigate how government communications rules on taxpayer-funded science impact public access to information.

Legault is responding to a detailed complaint lodged by the Environmental Law Centre at the University of Victoria and the ethics advocacy group Democracy Watch.

Their lengthy report — “Muzzling Civil Servants: A Threat to Democracy?” — laid out repeated examples of taxpayer-funded science being suppressed or limited to pre-packaged media lines across six different government departments and agencies.

…

Chris Tollefson, the executive director of UVic’s law centre, said their research into suppressed science revealed both the wide scope of the practice and that it “represents a significant departure” in government practice over the last five to seven years.

…Gary Goodyear, the minister of state for science and technology, was not available Monday to defend Conservative practices. His office provided an email stating government scientists “are readily available to share their research with the media and the public.”

“Last year, Environment Canada participated in more than 1,300 media interviews, Agriculture and Agri-Food Canada issued nearly 1,000 scientific publications, and Natural Resources Canada published nearly 500 studies,” said the statement.

It came the same day that the Globe and Mail reported that the National Research Council declined to make available its lead engineer for a front page story on research into truck safety. [emphases mine]

“Great spin — but missing the point,” Democracy Watch’s Duff Conacher said of the government response.

“It’s not the number of documents, it’s what percentage of documents are being released.”

Truck safety? That seems an odd topic for which to suppress or restrict any discussion with the lead engineer. But then, why withdraw from a treaty to save $350,000? As for the recycled announcement about funding for food and agriculture projects in Asia when you have substantive perception issues regarding  Africa and having someone who hasn’t lived in the country for 12 years defending your policies, the whole thing seems rather inept.

Simon Fraser University completes a successful mating dance while TRIUMF (Canada’s national laboratory for particle and nuclear physics) gets its groove on

The Federal Government of Canada in the guise of the Canada Foundation for Innovation has just awarded $7.7M to Simon Fraser University (SFU) and its partners for a global innovation hub. From the Jan. 15, 2013 Canada Foundation for Innovation news release,

British Columbia’s research-intensive universities are coming together to create a global hub for materials science and engineering. Simon Fraser University, the University of Victoria, the University of British Columbia and the British Columbia Institute of Technology have received $7.7 million in funding from the Canada Foundation of Innovation to create the Prometheus Project — a research hub for materials science and engineering innovation and commercialization.

“Our goal with the Prometheus Project is to turn our world-class research capacity into jobs and growth for the people of British Columbia,” said Neil Branda, Canada Research Chair in Materials Science at Simon Fraser University and leader of the Prometheus Project. “We know that materials science is changing the way we create energy and fight disease. We think it can also help B.C.’s economy evolve.”

This project builds on a strong collective legacy of collaborating with industry. Researchers involved in the Prometheus Project have created 13 spin-off companies, filed 67 patents and have generated 243 new processes and products. [emphasis mine] Branda himself has founded a company called Switch Materials that seizes the power of advanced chemistry to create smarter and more efficient window coatings.

This funding will allow members of the research team to build their capacity in fabrication, device testing and advanced manufacturing, ensuring that they have the resources and expertise they need to compete globally.

There’s a bit more information about the Prometheus project in a Jan.15, 2013 backgrounder supplied by SFU,

Led by Neil Branda, a Canada Research Chair in Materials Science and SFU chemistry professor, The Prometheus Project is destined to become a research hub for materials science and engineering innovation, and commercialization globally.

It brings together 10 principal researchers, including Branda, co-founder of SFU’s 4D LABS (a materials research facility with capabilities at the nanoscale], and 20 other scientists at SFU, University of British Columbia, the University of Victoria and the British Columbia Institute of Technology. They will create new materials science and engineering (MS&E) technology innovations, which will trigger and support sustained economic growth by creating, transforming and making obsolete entire industries.

Working with internationally recognized industrial, government, hospital and academic collaborators, scientists at the Prometheus partners’ labs, including 4D LABS, a $40 million materials science research institute, will deliver innovations in three areas. The labs will:

  • Develop new solar-industry related materials and devices, including novel organic polymers, nanoparticles, and quantum dots, which will be integrated in low cost, high efficiency solar cell devices. The goal is to create a new generation of efficient solar cells that can compete in terms of cost with non-renewable technologies, surpassing older ones in terms of miniaturization and flexibility.
  • Develop miniaturized biosensors that can be used by individuals in clinical settings or at home to allow early detection of disease and treatment monitoring. They will be integrated into flexible electronic skins, allowing health conditions to be monitored in real-time.
  • Develop spintronics (magnetic devices) and quantum computing and information devices that will enable new approaches to significantly improve encrypted communication and security in financial transactions.

“This project will allow B.C.’s four most research intensive institutes to collaborate on fundamental materials research projects with a wide range of potential commercial applications,” notes Branda. “By engaging with a large community of industry, government and NGO partners, we will move this research out of the lab and into society to solve current and future challenges in important areas such as energy, health and communications.”

The Prometheus team already has a strong network of potential end users of resulting technologies. It is based on its members’ relationships with many of more than 25 companies in BC commercializing solar, biomedical and quantum computing devices.

Researchers and industries worldwide will be able to access Prometheus’s new capabilities on an open-access basis. [emphasis mine]

There are a few things I’d like to point out (a) 13 spin-off companies? There’s no mention as to whether they were successful, i.e., created jobs or managed a life beyond government funding. (b) Patents as an indicator for innovation? As I’ve noted many, many times that’s a very problematic argument to make. (c) New processes and products? Sounds good but there are no substantiating details.  (d) Given the emphasis on commercializing discoveries and business, can I assume that open-access to Prometheus’ capabilities means that anyone willing and able to pay can have access?

In other exciting SFU news which also affects TRIUMF, an additional $1M is being awarded by the Canada Foundation for Innovation to upgrade the ATLAS Tier-1 Data Analysis Centre. From the SFU backgrounder,

Led by Mike Vetterli, a physics professor at SFU and TRIUMF, this project involves collaborating with scientists internationally to upgrade a component of a global network of always-on computing centres. Collectively, they form the Worldwide Large Hadron Collider Computing Grid (WLCG).

The Canadian scientists collaborating with Vetterli on this project are at several research-intensive universities. They include Carleton University, McGill University, University of British Columbia, University of Alberta, University of Toronto, University of Victoria, Université de Montréal, and York University, as well as TRIUMF. It’s Canada’s national lab for particle and nuclear physics research.

The grid, which has 10 Tier-1 centres internationally, is essentially a gigantic storage and processing facility for data collected from the ATLAS  experiment. The new CFI funding will enable Vetterli and his research partners to purchase equipment to upgrade the Tier-1 centre at TRIUMF in Vancouver, where the equipment will remain.

ATLAS is a multi-purpose particle detector inside a massive atom-smashing collider housed at CERN, the world’s leading laboratory for particle physics in Geneva, Switzerland.

More than 3,000 scientists internationally, including Vetterli and many others at SFU, use ATLAS to conduct experiments aimed at furthering global understanding of how the universe was physically formed and operates.

The detector’s fame for being a window into nature’s true inner workings was redoubled last year. It helped scientists, including Vetterli and others at SFU, discover a particle that has properties consistent with the Higgs boson.

Peter Higgs, a Scottish physicist, and other scientists theorized in 1964 about the existence of the long-sought-after particle that is central to the mechanism that gives subatomic particles their mass.

Scientists now need to upgrade the WLCG to accommodate the massive volume of data they’re reviewing to confirm that the newly discovered particle is the Higgs boson. If it is, it will revolutionize the way we see mass in physics.

“This project will enable Canadian scientists to continue to play a leading role in ATLAS physics analysis projects such as the Higgs boson discovery,” says Vetterli. “Much more work and data are required to learn more about the Higgs-like particle and show that it is indeed the missing link to our understanding of the fundamental structure of matter.

There is one more Canada Foundation for Innovation grant to be announced here, it’s a $1.6M grant for research that will be performed at TRIUMF, according to the Jan. 13, 2013 news release from St. Mary’s University (Halifax, Nova Scotia),

Dr. Rituparna Kanungo’s newest research collaboration has some lofty goals: improve cancer research, stimulate the manufacturing of high-tech Canadian-made instrumentation and help explain the origin of the cosmos.

The Saint Mary’s nuclear physicist’s goal moved one step closer to reality today when the federal government announced $1.6 million in support for an advanced research facility that will allow her to recreate, purify, and condition rare isotopes that haven’t existed on the planet for millions of years.

The federal fiscal support from the Canada Foundation for Innovation together with additional provincial and private sector investment will allow the $4.5 million project to be operational in 2015.

“The facility will dramatically advance Canada’s capabilities for isolating, purifying, and studying short-lived isotopes that hold the key not only for understanding the rules that govern the basic ingredients of our everyday lives but also for crafting new therapies that could target and annihilate cancers cell-by-cell within the human body, “ said Dr Kanungo.

The CANadian Rare-isotope facility with Electron-Beam ion source (CANREB) project is led by Saint Mary’s University partnering with the University of Manitoba and Advanced Applied Physics Solutions, Inc. in collaboration with the University of British Columbia, the University of Guelph, Simon Fraser University, and TRIUMF. TRIUMF is Canada’s national laboratory for particle and nuclear physics. It is owned and operated as a joint venture by a consortium of Canadian universities that includes Saint Mary’s University.

…

As one of the nation’s top nuclear researchers (she was one of only two Canadians invited to speak at a Nobel Symposium last June about exotic isotopes), Dr. Kanungo has been conducting research at the TRIUMF facility for many years, carrying out analyses from her office at Saint Mary’s University together with teams of students. Her students also often spend semesters at the Vancouver facility.

As the project leader for the new initiative, she said TRIUMF is the ideal location because of its world leading isotope-production capabilities and its ability to produce clean, precise, controlled beams of selected exotic isotopes not readily available anywhere else in the world.

In recent studies in the U.S., some of these isotopes have been shown to have dramatic impact in treating types of cancer, by delivering radioactive payloads directly to the cancerous cells. Canada’s mastery of the technology to isolate, study, and control these isotopes will change the course of healthcare.

An integral part of the project is the creation of a new generation of high resolution spectrometer using precision magnets. Advanced Cyclotron Systems, Inc. a company in British Columbia, has been selected for the work with the hope that the expertise it develops during the venture will empower it to design and build precision-magnet technology products for cutting-edge projects all around the world.

Exciting stuff although it does seem odd that the federal government is spreading largesse when there’s no election in sight. In any case, bravo!

There’s one last piece of news, TRIUMF is welcoming a new member to its board, from its Jan. 14, 2013 news release,

Dr. Sylvain Lévesque, Vice-President of Corporate Strategy at Bombardier Inc., a world-leading manufacturer of innovative transportation solutions, has joined the Board of Management for TRIUMF, Canada’s national laboratory for particle and nuclear physics, for a three-year term.  Owned and operated by a consortium of 17 Canadian universities with core operating funds administered via a contribution agreement through National Research Council Canada, TRIUMF is guided by a Board that includes university vice-presidents of research, prestigious scientists, and leading members of Canada’s private sector.

Paul Young, Chair of TRIUMF’s Board and Vice President, Research at the University of Toronto, said, “We welcome the participation of Sylvain and his extensive experience at Bombardier.  TRIUMF is a national resource for basic research and yet we also fulfill a technological innovation mission for Canada.  Dr. Lévesque will be a valuable addition to the Board.”

Dr. Sylvain Lévesque earned his Ph.D. from MIT in Engineering and worked at McKinsey & Company before joining Bombardier in 1999.  He brings deep experience with large, technical organizations and a passion for science and engineering. [emphasis mine]  He said, “I am excited to work more closely with TRIUMF.  It has a track record of excellence and I am eager to provide guidance on where Canada’s industrial sector might draw greater strength from the laboratory.”

TRIUMF’s Board of Management reflects the unique status of TRIUMF, a laboratory operating for more than forty years as a joint venture from Canada’s leading research universities.  The consortium includes universities from Halifax to Victoria.

Is deep experience like wide experience or is it a whole new kind of experience helpful for ‘getting one’s groove on’? For anyone who’s curious, ‘getting one’s groove on’ involves dancing.

Viruses mine for copper at the University of BC; microscopy at the University of Victoria; the Henry Louis Gates Jr. affair, human nature, & human enhancement

Professor Scott Dunbar at the University of British Columbia’s (Canada) Norman B. Keevil Institute of Mining Engineering needed to partner with colleagues Sue Curtis and Ross MacGillivray from the Centre for Blood Research and the Department of Biochemistry and Molecular Biology after (from the media release on Nanowerk News),

“I read an article about bacteriophage – viruses that infect bacteria – being used to create nanodevices in which proteins on the phage surface are engineered to bind to gold and zinc sulfide,” says Dunbar. “And it struck me: if zinc sulfide, why not copper sulfide? And if so, then it might be possible to use these bio-engineered proteins to separate common economic sulfide minerals from waste during mineral extraction.”

Together the researchers have developed a procedure called “biopanning.” It’s a kind of genetic engineering which could lead to some useful applications.

It turns out that the phage that bind to a mineral do affect the mineral surfaces, causing them to have a different electrical charge than other minerals. The proteins on the phage also form links to each other leading to aggregation of the specific sulfide particles. “The physical and chemical changes caused by phage may be the basis for a highly selective method of mineral separation with better recovery. Another possible application is bioremediation, where metals are removed from contaminated water” says Dunbar.

In other BC news, the University of Victoria (Canada) will be getting a new microscope which senses at subatomic levels. (From the media release on Azonano),

The new microscope-called a Scanning Transmission Electron Holography Microscope (STEHM) — will use an electron beam and holography techniques to observe the inside of materials and their surfaces to an expected resolution as small as one-fiftieth the size of an atom.

This is being done in collaboration with Hitachi High-Technologies which is building the microscope in Japan and installing it at U Vic in late 2010. The microscope will be located in a specially adapted room where work to prepare and calibrate it will continue until it becomes operational sometime in 2011.

After my recent series on robots and human enhancement, I feel moved to comment on the situation in the US vis a vis Henry Louis Gates, Jr. and his arrest by the police officer, James Crowley. It’s reported here and elsewhere that neither the recording of the 911 call nor the concerned neighbour who made the call support Sergeant Crowley’s contention that the two men allegedly breaking into the house were described as ‘black’.

Only the participants know what happened and I don’t fully understand the nuances of race, class, and cultural differences that exist in the US so I can’t comment on anything other than this. It is human to hear what we expect to hear and I have an example from a much less charged situation.

Many years ago, I was transcribing notes from a taped interview (one of my first) for an article that I was writing for a newsletter. As I was transcribing, I noticed that I kept changing words so that the interview subject sounded more like me. They were synonyms but they were my words not his. Over the years I’ve gotten much better at being more exact but I’ve never forgotten how easy it is to insert your pet words (biased or not) when you’re remembering what someone said. Note: I was not in a stressful situation and I could rewind and listen again at my leisure.

I hope that Crowley and Gates, Jr. are able to work this out in some fashion and I really hope that it is done in a way that is respectful to both men and not a rush to a false resolution for the benefit of the cameras. For a more informed discussion of the situation, you may find this essay by Richard Thompson Ford  in Slate helpful. It was written before the recording of the 911 call was made public but I think it still stands.

My reason for mentioning this incident is that human nature tends to assert itself in all kinds of situations including the building of robots and the debates on human enhancement, something I did not mention in my series posted (July 22 – 24, 27, 2009).
