INL, ISU team on nanoparticle production breakthrough
Idaho National Laboratory October 19th, 2009 Every hour, the sun floods Earth with more energy than the entire world consumes in a year. Yet solar power accounts for less than 0.002 percent of all electricity generated in the United States, primarily because photovoltaic cells remain expensive and relatively inefficient. But solar may not be such a marginal power source for long. Chemists at Idaho National Laboratory and Idaho State University have invented a way to manufacture highly precise, uniform nanoparticles to order. The technology, Precision Nanoparticles, has the potential to vastly improve the solar cell and further spur the growing nanotech revolution.

The truth about yams
jamaica-gleaner.com October 21st, 2009 It has taken 30 years of hard work for Professor Helen Asemota to get to this stage. However, that work is yet over. Yams and potatoes are foods many people don't think much of in Jamaica. They are always available and their use outside of being a replacement for our staple rice diet has not been thought of much. Professor Asemota has thought of it. Hailing from Nigeria, the professor of biochemistry and molecular biology in the department of medical sciences at the University of the West Indies (UWI) has made the journey across the middle passage and is daily achieving feats that benefit Jamaica in untold ways. Those benefits have earned Professor Asemota the 2009 Gleaner Honour Award in the category science and technology. Over those 30 years, and more, Professor Asemota has not only worked with a number of universities, but has been integral on a global level, of developing and executing new and improved research in her field. While her work in biochemistry, molecular biology and biotechnology is renowned, has recently she added the fairly new and certainly very exciting area of nanotechnology to her extensive résumé. Prof Asemota earned her professorial status at UWI but has found the time to also give service to Shaw University in North Carolina where she is head of the Nanobiology Division of the Shaw Nanotechnology Initiative - the Nanoscience and Nanotechnology Research Centre. So respected is the woman that though she is only with Shaw University part-time, she is also the chairman of the Shaw Institutional Research Board.

Russia's Medvedev blasts Putin-era state giants
news.my.msn.com October 21st, 2009 Russian President Dmitry Medvedev on Wednesday said the state should lessen its economic role, warning state corporations set up by his predecessor Vladimir Putin could ultimately cease to exist. "I believe that we at some point have let the creation of state corporations out of control," Medvedev told a meeting of leading tycoons at the Kremlin. "This does not mean that they should be shut down," he said, suggesting instead that they should be transformed into joint-stock companies. Joint-stock companies in Russia are divided between open joint-stock companies whose shares may be publicly traded and closed joint-stock companies whose shares are distributed among a limited number of shareholders. Under ex-president Vladimir Putin, now the prime minister, the government created a series of state champions to spur growth in sectors such as car making, civil aviation, nanotechnology, the nuclear industry and arms building.

€8m Purse for 15 Early Researchers
irishdev.com October 21st, 2009 Announcing the first Science Foundation Ireland (SFI) Starting Investigator Research Grant (SIRG) awards at the Royal College of Physicians yesterday, Minister for Science, Technology and Innovation: (Including) Dr. Paul Eastham (Trinity College Dublin) €474,506.50 Title: Strong interactions and collective effects in semiconductor optoelectronics Synopsis: Quantum dots are a kind of artificial atoms whose properties, e.g. the light they emit, can be manipulated in a very controlled manner. Quantum dots are nano-sized, man-made objects with a wide range of applications in optoelectronics, photonics and quantum computers. Dr Eastham and his team aim to investigate how quantum dots would interact with each other in laser or quantum computing devices. Dr. Nikolay Petkov (Tyndall National Insititute) €530,734.30 Title: Tuning surface and dopant properties of silicon and germanium Nanowires for high performance nanowire based field-effect transistors Synopsis: Over the years increased computer speed and capacity has been realized through a reduction of the size of the semiconductor components that make up the functional parts of the computers. The sizes are now nearing the nanometer regime where the components will have dimensions of no more than a few tens or hundreds of atoms. Nanotechnology, the manipulation of matter on an atomic scale, will in the next decade allow faster and more efficient computers. Dr Petkov and his team will contribute to the transition to nanotechnology computers by investigating nanowires made from silicon and germanium for use as transistors. Dr. Ray Duffy (Tyndall National Institute) €562,546.80 Title: N-type doping in germanium for sub-20nm technology CMOS devices Synopsis: One of the key factors in the coming of the modern Information Age has been the rapid increase of computational power. This has been led by the semiconductor device manufacturing industry which is constantly improving the speed and power of computer chips. This is done by manufacturing the components as small as possible. The state of the art in semiconductor device manufacturing is a process that creates features that are 45 nanometres wide. This proposal studies the use of germanium instead of silicon as one possible way to allow for sub 20 nanometre technologies. Dr. Michael Nolan (Tyndall National Institute) €472,244.40 Title: Engineering Metal Oxide Interfaces For Renewable Energy Photocatalysis Synopsis: Artificial photosynthesis is the process where light energy is used to split water into hydrogen and oxygen. The hydrogen can then be used as a clean, renewable, easy to store, environmentally friendly fuel. Currently however the efficiency of the reaction is not high enough for the process to be viable. New materials could sufficiently improve the efficiency and speed of the reaction. The proposal will study metal oxides that have particular structures when measured on the nanometer scale. These metal oxides could be suitable new materials for the artificial photosynthesis process.

Germany warns over dangers of nanotechnology
dw-world.de October 22nd, 2009 German authorities have warned of the risks posed by nanotechnology when used in food, clothing, cosmetics and other products. The promising potential of the technology comes with a risk for health and environment. Professor Dieter Stuermer from the Bonn-based Institute for Science and Ethics says people should be especially aware of the danger that nano particles can damage lungs and cause inflammation. In particular, he criticizes nanotechnology companies for not taking enough account of the possible negative side-effects of their products. Urban Wiesing from Tuebingen University: "I strongly believe that many of the risks associated with nanotechnology have at least in part been encountered in other technologies as well," he told Deutsche Welle. "That's why I'm confident that regulations can be found to ensure that these risks can be minimized in the interests of the users of nano products."

Terepac, IMEC Partner for Low-cost Flexible Electronics
electroiq.com October 22nd, 2009 Terepac Corporation and research center IMEC will collaborate on novel packaging technologies for flexible electronics. The initial driver for this shared research is a next-generation wireless ECG system, developed in the Human++ Program at Holst Centre, Eindhoven. For many applications, like on-the-body devices, thin and flexible form factors greatly improve the comfort of wearable electronics. To allow large-scale manufacturing and market penetration, low-cost/high-value solutions are targeted in R&D programs. Traditional electronics packaging and assembly with rigid printed circuit boards (PCBs) and pick-and-place machines are unable to cope with these demands, the research partners assert.

Is Nanotechnology Dangerous?
spiegel.de October 22nd, 2009 Christoph Seidler: A background paper by Germany's Federal Environment Agency earlier this week triggered fearful headlines in some of the country's biggest newspapers. But the agency is distancing itself from the coverage, saying it had presented nothing new in the report -- and that it also sees opportunities in nano. Breathless headlines about nanotechnology have ruffled feathers at Germany's Federal Environment Agency (UBA) this week. "Nanotechnology can make you sick," and "First official warning in Germany" about the dangers of nanotechnology, the headlines read. "The German Environment Agency warns against nanotechnology." The maelstrom began earlier this week, when UBA specialists posted a 28-page paper about nanotechnology on their Web site -- a move that prompted a very vocal response. But officials at the agency feel they have been misunderstood. They claim the posting is neither a warning nor a new study -- it's just a background paper. "We haven't done any of our own research," UBA scientist Wolfgang Dubbert told SPIEGEL ONLINE. Dubbert is one of the authors of the paper, an updated version of a document published in 2006.

£1m research boost for ‘intelligent’ nano self-assembly
Nottingham University October 22nd, 2009 What if material structures could ‘build themselves' by self-assembling their molecules — guided by ‘artificial intelligence'?

Researchers Testing Nanotech for Hazardous Waste Cleanups
nytimes.com October 23rd, 2009 Scientists and environmental regulators are hoping that some extremely tiny materials might make a huge difference in hazardous waste cleanups. Researchers are exploring whether nanoscale materials -- so named because they are as small as 1/100,000 the width of a human hair -- can be cleanup assets. They have two reasons for optimism: Nanomaterials' size lets them penetrate otherwise impossible-to-reach groundwater or soil, and their engineered coatings allow them to stay suspended in groundwater, a major asset in cleanups. If they work, nanomaterials could slash cleanup prices by avoiding the extraordinary costs and risks of hauling materials away for burning or burial. "There is significant potential to target a number of very complicated sites that to date we have been unable to remediate adequately," said Denis O'Carroll, an assistant professor of civil and environmental engineering at the University of Western Ontario.

Rensselaer To Lead Multimillion-Dollar Research Center for Social and Cognitive Networks
