Purdue University’s Network for Computational Nanotechnology has received a five-year, $18.25 million grant from the National Science Foundation to support the U.S. National Nanotechnology Initiative with expanded capabilities and services for computer simulations, NSF and Purdue officials announced Thursday (Sept. 20).  The national network was launched in 2002 with $10.5 million from NSF to develop sophisticated, high-powered computational tools that allow scientists from Boston to Beijing to advance nano-related research simply by using their desktop computers.

The Network for Computational Nanotechnology  has received a five-year, $18.25M grant from the National Science Foundation to advance the simulation capabilities of the network. The site, which is based at Purdue University (West Lafayette, Ind.), also offers on-line courses and other information on nanoelectronics, nanomedicine and nanomaterials.    The network interface is the “nanoHUB,” a free, Internet-based gateway used by more than 3,000 national and international researchers and educators every month. In the last 12 months, 5,700 users have run more than 220,000 simulations with 50 available simulation tools. The simulations support creation of new medicines, sensors for homeland security, environmental monitoring and other applications.

In the race to make clean technologies more efficient and marketable a breakthrough has been made by Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), collaborating with Innovalight, Inc., showing that a new and important effect called Multiple Exciton Generation (MEG) occurs efficiently in silicon nanocrystals.  MEG results in the formation of more than one electron per absorbed photon, increasing the amount of light that is converted into usable electricity which is a key step toward making solar energy more cost-competitive with conventional power sources.

The Indian government would shortly introduce nanotechnology courses in all universities in a bid to produce nanoscientists. Disclosing this at 5th Knowledge Millennium Summit organised by ASSOCHAM, Minister of State for Human Resource Development Dr D Purandeswari said nano faculties and courses would first commence in University of Kolkata, Mumbai and Chennai, which have completed almost 150 years of their creation.  Subsequently, the nano courses and faculties could be extended in all other universities across the country.

A conceivable result could be nanosized, color-to-order lasers for sensing and optical interconnect.

Victor I Klimov, PhD, leads a team at Los Alamos National Laboratory that has been working for a number of years on turning NQDs (nanocrystal quantum dots) into lasers. Because the dots are so small, their size influences the energy gap between the conduction and the valence bands. When the recombination of an electron-hole pair causes the release of light in a laser, the color of the light relates to the energy gap. Hence, Klimov and company could change the color of an NQD laser simply by fabricating larger or smaller dots—if they could get the NQDs to be lasers.

Scientists in Israel have developed a simple way of making complex networks of carbon nanotubes and stamping them onto circuit boards, taking a further step towards building the next generation of smaller, faster microchips.   Nanotubes are strong, easy to make and excellent conductors of electricity but, to date, manipulating the tiny tubes has proven tricky. But now a team led by Yael Hanien at Tel-Aviv University in Israel has demonstrated a robust and cheap method of arranging carbon nanotubes on different surfaces.

Alexander Star, a chemistry professor in the University of Pittsburgh’s School of Arts and Sciences, is leading a team in developing a sensor that could detect an asthma attack before its onset.  Asthma is a reaction to certain stimuli that irritate the respiratory system, and the symptoms of asthma range from mild to life threatening.  In particular, an asthma sufferer could negatively respond to an environmental stimulant (or allergen), cold air or emotional stress, according to the World Health Organization.

Nanotubes historically have been synonymous with organic carbon nanotubes, but no more.  Researchers at the Georgia Institute of Technology (Atlanta) have defined a new class of inorganic nanotube materials that are analogous to volcanically formed minerals found in Japan and New Zealand. By combining aluminum oxide with silicon and germanium, professor Sankar Nair’s group at Georgia Tech claims to have defined a new class of single-walled nanotube that is less expensive to fabricate than carbon nanotubes, offering properties that are easier to control.
