It's commonly accepted that electrical resistance of a given material cannot be adjusted as is the case with, for example, density and color. However, Dr Meike Stöhr and her collaborators have now succeeded in developing a new method to selectively tune surface properties such as resistance.
Scientists at DuPont and Lehigh University have refined a technique, first published in 2003, to sort carbon nanotubes using specific sequences of DNA. This technique offers the first demonstration that nanotubes can be sorted by size, property and symmetry (chirality).
The New York Times carries an article today on how universities are investing in nanotechnology start-ups and California's university research centers, small companies and venture finance firms are collaborating in this area.
The University of Queensland's Australian Institute for Bioengineering and Nanotechnology and the Nanobiotechnology Center (NBTC) at Cornell University in the United States are working together to develop new products and techniques that will promote new medicines, develop the next generation of biofuels and improve human health and quality of life.
A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy's Pacific Northwest National Laboratory will determine if their innovative approach can safely and economically extract and convert heat from vast untapped geothermal resources.
Air Force Office of Scientific Research-funded researchers at the University of Rochester are using laser light technology that will help the military create new forms of metal that may guide, attract and repel liquids and cool small electronic devices.
An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale.
NanoTecNexus and the University of California, San Diego NanoTumor Center (NTC) have received the 2009 Bronze Telly Award for the production of a video on approaches to fighting cancer using nanotechnology.
