Zimbabwe and its international nanotechnology center, ZINC

A Sept.24, 2012 news item on Nanowerk provides information about a new nanotechnology center in Zimbabwe,

With 14 percent of Zimbabwe’s population living with HIV/AIDS and tuberculosis as a co-infection, the need for new drugs and new formulations of available treatments is crucial.

To address these issues, two of the University at Buffalo’s [UB] leading research centers, the Institute for Lasers, Photonics and Biophotonics (ILPB), and the New York State Center of Excellence in Bioinformatics and Life Sciences have signed on to launch the Zimbabwe International Nanotechnology Center (ZINC) — a national nanotechnology research program — with the University of Zimbabwe (UZ) and the Chinhoyi University of Technology (CUT).

This collaborative program will initially focus on research in nanomedicine and biosensors at UZ and energy at CUT. ZINC has grown out of the NIH [US National Institute of Health] Fogarty International Center, AIDS International Training and Research Program (AITRP) that was awarded to UB and UZ in 2008 to conduct HIV research training and build research capacity in Zimbabwe and neighboring countries in southern Africa.

I decided to find out more about Zimbabwe and found a map and details in a Wikipedia essay,

Location of Zimbabwe within the African Union (accessed Sept. 24, 2012 from the Wikipedia essay on Zimbabwe)

Zimbabwe (… officially the Republic of Zimbabwe) is a landlocked country located in Southern Africa, between the Zambezi and Limpopo rivers. It is bordered by South Africa to the south, Botswana to the southwest, Zambia and a tip of Namibia to the northwest (making this area a quadripoint) and Mozambique to the east. The capital is Harare. Zimbabwe achieved recognised independence from Britain in April 1980, following a 14-year period as an unrecognised state under the predominantly white minority government of Rhodesia, which unilaterally declared independence in 1965. Rhodesia briefly reconstituted itself as black-majority ruled Zimbabwe Rhodesia in 1979, but this order failed to gain international acceptance.

Zimbabwe has three official languages: English, Shona and Ndebele.

Getting back to Zimbabwe, Alan on the Science Business website posted on Sept. 24, 2012 about ZINC and the partnership (excerpted from the posting),

University at Buffalo in New York and two universities in the southern African nation of Zimbabwe will collaborate on a new nanotechnology research program in pharmacology. University of Zimbabwe in Harare and the Chinhoyi University of Technology in Mashonaland West, working with Buffalo’s Institute for Lasers, Photonics, and Biophotonics, along with New York State Center of Excellence in Bioinformatics and Life Sciences also on the Buffalo campus, will establish the Zimbabwe International Nanotechnology Center (ZINC).

ZINC aims to develop an international research and training capability in nanotechnology that advances the field as contributor to Zimbabwe’s economic growth. The collaboration is expected to focus on research in nanomedicine and biosensors for health care at University of Zimbabwe, while the Chinhoyi University of Technology partnership will conduct research related to energy.

The University of Buffalo Sept. 24, 2012 news release provides more details,

The UB ILPB and TPRC [Translational Pharmacy Research Core] collaboration recognized that the fields of pharmacology and therapeutics have increasingly developed links with emerging areas within the field of nanosciences in an attempt to develop tissue/organ targeted strategies that will lead to disease treatment and eradication. Research teams will focus on emerging technologies, initially focused in nanobiotechnology and nanomedicine for health care.

“Developing nanoformulations for HIV and tuberculosis diagnostics and therapeutics, as well as new tuberculosis drug development, are just a few of the innovative strategies to address these co-infections that this research collaboration can provide,” said Morse [Gene D. Morse, PharmD, Professor of Pharmacy Practice, associate director of the New York State Center of Excellence in Bioinformatics and Life Sciences and director of the Translational Pharmacy Research Core {TPRC}].

“In addition, the development of new nanotechnology-related products will jumpstart the economy and foster new economic initiatives in Zimbabwe that will yield additional private-public partnerships.”

Morse says that the current plans for a “Center of Excellence” in clinical and translational pharmacology in Harare at UZ will create a central hub in Africa, not just for Zimbabwe but for other countries to gain new training and capacity building in many exciting aspects of nanotechnology as well.

Good luck to ZINC and its partners!

Pricoil and nanotechnology-enabled products in Ghana

Pricoil Ghana received an award for African technology innovation from Frost & Sullivan in early November 2011. (Canada’s Vive Nano received a similar award [North American technology innovation] in 2010 as noted in my June 25, 2010 posting.) From the Nov. 18, 2011 news item on Modern Ghana.com,

Pricoil Ghana has won the African Infrastructure Chemicals and Materials Technology Innovation Award for the Year 2011 at the African Excellence Awards Banquet in Cape Town, South Africa.

The Award was in recognition of the company’s ability to leverage nanotechnology in the waterproofing industry.

“Nanotechnology is a relatively new technology in the global market and Pricoil’s introduction of the technology into the African market in Ghana is being recognized by this award,” a citation accompanying the award noted.

Frost and Sullivan, a Global Research Platform with over 50 years experience and the awardees said Pricoil Ghana had addressed some key industry challenges facing the continent through the use of their technology innovation strategies.

Frost and Sullivan, the awardees, indicated that products using solvents had been noted to contain volatile organic compounds (VOC’s) which had been shown to have adverse effects on human health and the environment and could be harmful to people. Globally, there is a widespread movement toward the uptake of water based manufacturing processes, moving away from solvent based production.

…

Frost and Sullivan further stated that in the Ghana market, there were approximately 10 large companies involved in the supply of waterproofing material. The major products which are used in the market are touch on products such as bituminous material.

I got a little more information about the award from the Nov.3, 2011 news release from Frost & Sullivan,

Frost & Sullivan presented awards to thirteen innovators and industry leaders at its prestigious 2011 African Excellence Awards Banquet last night. The annual awards banquet, held at The Westin hotel, honoured companies for outstanding performance across a spectrum of industries, ranging from renewable energy to infrastructure, chemicals and materials, broadband, uninterruptible power supplies, data centres and private power production.

“Frost & Sullivan acknowledges exceptional industry achievements and demonstration of best practices by presenting awards to top companies in regional and global markets,” said Frost & Sullivan’s Operations Manager and Consulting Director for Africa, Hendrik Malan. “Awardees have demonstrated innovation, competitiveness and leadership in meeting the particular demands of doing business in Africa. The products and services that we recognise are examples of how to effectively manage business in the current economic climate.”

As for Frost & Sullivan itself (I always find the investigation of just who is giving the award interesting), I saw this in a Wikipedia essay,

Frost & Sullivan, Inc. is an American firm which provides market research & analysis, growth strategy consulting and corporate training services. Its headquarters are located in San Antonio, Texas, with offices in over 20 countries across the world.

Congratulations to the folks at Pricoil.

Nigeria and nanotechnology

ETC group, nanotechnology and Africa

There’s a lot of valuable information and insight along with an almost old-fashioned approach to the politics in the October 6, 2010 article, Big continent and tiny technology: Nanotechnology and Africa, by Kathy Jo Wetter of the ETC Group. The article is well written and researched. Here’s an excerpt from the its technical explanation of nanotechnology,

Nanotechnology is a suite of techniques used to manipulate matter on the scale of atoms and molecules. Nanotechnology speaks solely to scale: Nano refers to a measurement, not an object. A nanometre (nm) equals one-billionth of a metre. Ten atoms of hydrogen lined up side-by-side equal one nanometre. A DNA molecule is about 2.5nm wide (which makes DNA a nanoscale material). A red blood cell is enormous in comparison: about 5,000nm in diameter. Everything on the nanoscale is invisible to the unaided eye and even to all but the most powerful microscopes….

Key to understanding the potential of nanotech is that, at the nanoscale, a material’s properties can change dramatically; the changes are called ‘quantum effects’. With only a reduction in size (to around 300nm or smaller in at least one dimension) and no change in substance, materials can exhibit new characteristics – such as electrical conductivity, increased bioavailability, elasticity, greater strength or reactivity – properties that the very same substances may not exhibit at larger scales. For example, carbon in the form of graphite (like pencil ‘lead’) is soft and malleable; at the nanoscale carbon can be stronger than steel and is six times lighter; nanoscale copper is elastic at room temperature, able to stretch to 50 times its original length without breaking.

The point that some countries might choose to block the importation of nanomaterials due to issues around risk (as per the participants in a regional awareness-raising workshop in the Côte d’Ivoire) is well taken. From the article,

Here was a group of experts in Africa questioning the received wisdom of nanotechnology’s central role in solving the problems of the developing world, even going so far as to suggest that in some cases it may make sense to ‘say no to nano’.

I thought this next passage was particularly cogent,

Because nanoscale manipulations are now possible and, because the basic components of both living and non-living matter exist on the nanoscale (e.g., atoms, molecules and DNA), it is now possible to converge technologies to an unprecedented degree. Technological convergence, enabled by nanotechnology and its tools, can involve biology, biotechnology and synthetic biology, physics, material sciences, chemistry, cognitive sciences, informatics, geoengineering, electronics and robotics, among others. At the nanoscale there is no qualitative difference between living and non-living matter.

I first came across the statement about there being no appreciable gap between living and nonliving matter in a book about philosopher Alfred North Whitehead’s work, Process and Reality (which was written in the late 1920s). At the time, that statement affected my thinking profoundly and forced me to examine my assumptions about the boundaries between living and nonliving matter.

Getting back to the article, the section about market impact is interesting and problematic for me,

The most direct impact of new designer materials created using nanotechnology is multiple raw-material options for industrial manufacturers, which could mean major disruptions to traditional commodity markets. It is too early to predict with certainty which commodities or workers will be affected and how quickly. However, if a new nano-engineered material outperforms a conventional material and can be produced at a comparable cost, it is likely to replace the conventional commodity. History shows that there will be a push to replace commodities such as cotton and strategic minerals – both heavily sourced in Africa and critical export earners – with cheaper raw materials that can be sourced or manufactured by new processes closer to home.

Yes, if manufacturers can find a way to make their products cheaper, they will certainly do that regardless of whom may get hurt as Americans found out when production of various electronics products was outsourced to places where labour is cheaper. As for reliance on commodities for export, Canadians know that story well.

What seems to have been ignored in Wetter’s article is the pressure to produce more closer to home for environmental reasons. It’s at this point that the article starts to lose credibility for me.

The section on Health and Environmental Aspects is carefully designed to evoke great concern while remaining nominally truthful,

While there is great uncertainty about the toxicity of nanoparticles, hundreds of published studies now exist that show manufactured nanoparticles, currently in widespread commercial use (including zinc, zinc oxide, silver and titanium dioxide) can be toxic.

Damning all uses of the nanoparticles (as named in the article) seems as helpful as announcing that peanuts,which are in widespread commercial use, can be toxic. Interestingly, the author does not mention the use of zinc oxide and/or titanium dioxide nanoparticles in sunscreens which have been given a cautious passing grade by the Environmental Working Group (EWG). (I last posted about nanosunscreens and the EWG, June 16, 2010.)

Yes, people should have concerns and more research on environmental and health impacts of nanomaterials and nanotechnology-enabled products is urgently needed but the article, unless very carefully read, could be deemed misleading with regard to health and environmental impacts.

The section I was specifically referring to when I described this article has having an old-fashioned approach to the politics comes at the end with, Who’s in Control?,

Many who envision nanotech bringing benefits to Africa ignore the realities of technology transfer and intellectual property. Intellectual property is being driven by the North and promotes the interests of dominant economic groups, both North and South. A 2006 study reported that Africa accounts for just 0.4 per cent of all patents granted throughout the world, while the United States and Europe together account for 81.8 per cent.

More than 12,000 patents in the field of nanotechnology have been awarded, granted over three decades (1976–2006) by the three offices responsible for most of the world’s nanotech patenting – the US Patent & Trademark Office (USPTO), the European Patent Office and the Japan Patent Office.[6] As of March 2010, close to 6,000 nanotech patents had been granted by the USPTO and a further 5,184 applications were waiting in the queue. Multinational corporations, universities and nanotech start-ups (primarily in the OECD countries) have secured ‘foundational patents’ on nanotech tools, materials and processes – that is, seminal inventions upon which later innovations are built – and nanotech ‘patent thickets’ are already causing concern in the US and Europe.

While I agree with much of the analysis, I think the author does not seem to be aware that China is quickly catching up (or has China already caught up?) to the US in terms of claiming patents for advances in science and technology.

The reference to North and South seems dated to me especially in light an alliance (as cited in the article itself) between India, Brazil and South Africa,

South Africa is also a player in a cooperative nanotech R&D programme under the India-Brazil-South Africa Dialogue Forum (IBSA). Nanotech is one area of science collaboration, led by India, funded by a US$3 million trilateral research pool.

The geopolitics are changing rapidly and couching the discussion about developing/emerging economies and nanotechnology in terms coined more than 30 years ago seems counterproductive. For anyone who’s interested, do read the article because there’s lots of good material but caution needs to be exercised.

About 10 years ago, I got interested in how the arts and sciences can inform each other when I was trying to organize an art/science event which never did get off the ground (although I still harbour hopes for it one day). It all came back to me when I read Dave Bruggeman’s (Pasco Phronesis blog) recent post about a new Creative Science Studio opening at the School of Cinematic Arts at the University of Southern California (USC). From Dave’s post,

It [Creative Science Studio] will start this fall at USC, where its School of Cinematic Arts makes heavy use of its proximity to Hollywood, and builds on its history of other projects that use science, technology and entertainment in other areas of research.

The studio will not only help studios improve the depiction of science in the products of their students, faculty and alumni (much like the Science and Entertainment Exchange), but help scientists create entertaining outreach products. In addition, science and engineering topics will be incorporated into the School’s curriculum and be supported in faculty research.

This announcement reminds me a little bit of an IBM/USC initiative in 2008 (from the news item on Nanowerk),

For decades Hollywood has looked to science for inspiration, now IBM researchers are looking to Hollywood for new ideas too.

The entertainment industry has portrayed possible future worlds through science fiction movies – many created by USC’s famous alumni – and IBM wants to tap into that creativity.

At a kickoff event at the USC School of Cinematic Arts, five of IBM’s top scientists met with students and alumni of the school, along with other invitees from the entertainment industry, to “Imagine the World in 2050.” The event is the first phase of an expected collaboration between IBM and USC to explore how combining creative vision and insight with science and technology trends might fuel novel solutions to the most pressing problems and opportunities of our time.

It’s interesting to note that the inspiration is two-way if the two announcements are taken together. The creative people can have access to the latest science and technology work for their pieces and scientists can explore how an idea or solution to a problem that exists in a story might be made real.

I’ve also noted that the first collaboration mentioned suggests that the Creative Science Studio will be able to “help scientists create entertaining outreach products.” My only caveat is that scientists too often believe that science communication means that they do all the communicating while we members of the public are to receive their knowledge enthusiastically and uncritically.

Moving on to the math that I mentioned in the head, there’s an announcement of a new paper that discusses the use of mathematics in cinematic special effects. (I believe that the word cinematic is starting to include games and other media in addition to movies.) From the news item on physorg.com,

The use of mathematics in cinematic special effects is described in the article “Crashing Waves, Awesome Explosions, Turbulent Smoke, and Beyond: Applied Mathematics and Scientific Computing in the Visual Effects Industry”, which will appear in the May 2010 issue of the NOTICES OF THE AMS [American Mathematical Society]. The article was written by three University of California, Los Angeles, mathematicians who have made significant contributions to research in this area: Aleka McAdams, Stanley Osher, and Joseph Teran.

Mathematics provides the language for expressing physical phenomena and their interactions, often in the form of partial differential equations. These equations are usually too complex to be solved exactly, so mathematicians have developed numerical methods and algorithms that can be implemented on computers to obtain approximate solutions. The kinds of approximations needed to, for example, simulate a firestorm, were in the past computationally intractable. With faster computing equipment and more-efficient architectures, such simulations are feasible today—and they drive many of the most spectacular feats in the visual effects industry.

This news item too brought back memories. There was a Canadian animated film, Ryan, which both won an Academy Award and involved significant collaboration between a mathematician and an animator. From the MITACS (Mathematics of Information Technology and Complex Systems) 2005 newsletter, Student Notes:

Karan Singh is an Associate Professor at the University of Toronto, where co-directs the graphics and HCI lab, DGP. His research interests are in artist driven interactive graphics encompassing geometric modeling, character animation and non-photorealistic rendering. As a researcher at Alias (1995-1999), he architected facial and character animation tools for Maya (Technical Oscar 2003). He was involved with conceptual design and reverse engineering software at Paraform (Academy award for technical achievement 2001) and currently as Chief Scientist for Geometry Systems Inc. He has worked on numerous film and animation projects and most recently was the R+D Director for the Oscar winning animation Ryan (2005)

Someone at Student Notes (SN) goes on to interview Dr. Singh (here’s an excerpt),

SN: Some materials discussing the film Ryan mention the term “psychorealism”. What does this term mean? What problems does the transition from realism to psychorealism pose for the animator, or the computer graphics designer?

KS: Psychorealism is a term coined by Chris {Landreth, film animator] to refer to the glorious complexity of the human psyche depicted through the visual medium of art and animation. The transition is not a problem, psychorealism is stylistic, just a facet to the look and feel of an animation. The challenges lies in the choice and execution of the metaphorical imagery that the animator makes.

Both the article and Dr. Singh’s page are well worth checking out, if the links between mathematics and visual imagery interest you.

Research on the African continent

Last week I received a copy of Thompson Reuters Global Research Report Africa. My hat’s off to the authors, Jonathan Adams, Christopher King, and Daniel Hook for including the fact that Africa is a continent with many countries, many languages, and many cultures. From the report, (you may need to register at the site to gain access to it but the only contact I ever get is a copy of their newsletter alerting me to a new report and other incidental info.), p. 3,

More than 50 nations, hundreds of languages, and a welter of ethnic and cultural diversity. A continent possessed of abundant natural resources but also perennially wracked by a now-familiar litany of post-colonial woes: poverty, want, political instability and corruption, disease, and armed conflicts frequently driven by ethnic and tribal divisions but supplied by more mature economies. OECD’s recent African Economic Outlook sets out in stark detail the challenge, and the extent to which current global economic problems may make this worse …

While they did the usual about challenges, the authors go on to add this somewhat contrasting information.

Yet the continent is also home to a rich history of higher education and knowledge creation. The University of Al-Karaouine, at Fez in Morocco, was founded in CE 859 as a madrasa and is identified by many as the oldest degree-awarding institution in the world.ii It was followed in 970 by Al-Azhar University in Egypt. While it was some centuries before the curriculum expanded from religious instruction into the sciences this makes a very early marker for learning. Today, the Association of African Universities lists 225 member institutions in 44 countries and, as Thomson Reuters data demonstrate, African research has a network of ties to the international community.

A problem for Africa as a whole, as it has been for China and India, is the hemorrhage of talent. Many of its best students take their higher degrees at universities in Europe, Asia and North America. Too few return.

I can’t speak for the details included in the report which appears to be a consolidation of information available in various reports from international organizations. Personally, I find these consolidations very helpful as I would never have the time to track all of this down. As well, they have created a graphic which illustrates research relationships. I did have to read the analysis in order to better understand the graphic but I found the idea itself quite engaging and as I can see (pun!) that as one gets more visually literate with this type of graphic that it could be a very useful tool for grasping complex information very quickly.

Diabetes and mice

Last week, I missed this notice about a Canadian nanotechnology effort at the University of Calgary. From the news item on Nanowerk,

Using a sophisticated nanotechnology-based “vaccine,” researchers were able to successfully cure mice with type 1 diabetes and slow the onset of the disease in mice at risk for the disease. The study, co-funded by the Juvenile Diabetes Research Foundation (JDRF), provides new and important insights into understanding how to stop the immune attack that causes type 1 diabetes, and could even have implications for other autoimmune diseases.

The study, conducted at the University of Calgary in Alberta, Canada, was published today [April 8, 2010?] in the online edition of the scientific journal Immunity.

NANO Magazine

In more recent news, NANO Magazine’s new issue (no. 17) features a country focus on Canada. From the news item on Nanowerk,

In a special bumper issue of NANO Magazine we focus on two topics – textiles and nanomedicine. We feature articles about textiles from Nicholas Kotov and Kay Obendorf, and Nanomedicine from the London Centre for Nanotechnology and Hans Hofstraat of Philips Healthcare and an interview with Peter Singer, NANO Magazine Issue 17 is essential reading, www.nanomagazine.co.uk.

…

The featured country in this issue is Canada [emphasis mine], notable for its well funded facilities and research that is aggressively focused on industrial applications. Although having no unifying national nanotechnology initiative, there are many extremely well-funded organisations with world class facilities that are undertaking important nano-related research.

I hope I get a chance to read this issue.
