Because environmental and health information on carbon nanotubes is incomplete and sometimes conflicting, an 'anticipatory governance' approach to the technology is needed, according to Mark Philbrick, post-doctoral researcher at the Center of Integrated Nanomechanical Systems at the University of California, Berkeley.
DNA is an outstanding nanoscale building material, as researchers led by Ned Seeman discovered thirty years ago. Seeman and his colleagues at the New York University have now used cross-shaped DNA tiles to produce an amazingly large grid structure that resembles woven fabric.
Researchers have demonstrated a new imaging tool for rapidly screening structures called single-wall carbon nanotubes, possibly hastening their use in creating a new class of computers and electronics that are faster and consume less power than today's.
Researchers were able to produce nanopillars that absorb light as well or even better than commercial thin-film solar cells, using far less semiconductor material and without the need for anti-reflective coating.
In einem Positionspapier zum verantwortungsvollen Umgang mit Nanomaterialien (greift die DGUV die Empfehlungen der Nanokommission auf und legt ihre Handlungsfelder fuer zielgerichtete Praeventionsaktivitaeten fest. Dabei empfiehlt es sich, den Arbeitsschutzgedanken bereits bei der Etablierung von Nanotechnologien in den Unternehmen zu verankern.
Risoe Energy Report 9 lists a wide range of energy technologies in the market with low or no emissions of greenhouse gases, describing how several of these will be made commercially available in the next decades.
While our direct knowledge of black holes in the universe is limited to what we can observe from thousands or millions of light years away, a team of Chinese physicists has proposed a simple way to design an artificial electromagnetic (EM) black hole in the laboratory.
In a move that holds great significance for the semiconductor industry, a team of researchers has created an alternative to conventional logic gates, demonstrated them in silicon, and dubbed them 'chaogates'. Simply put, they used chaotic patterns to encode and manipulate inputs to produce a desired output.
Sheng Dai, a researcher in the Chemical Sciences Division of the Department of Energy's Oak Ridge National Laboratory, has earned the UT-Battelle Director's Award for Outstanding Individual Accomplishment in Science and Technology. He was honored for world-class leadership in the synthesis and application of novel functional porous materials, nanomaterials and ionic liquids to energy-relevant problems.
While a range of ingenious man-made materials bring us ever closer to realising the possibility of cloaking objects from visible light, research from Imperial College London is now taking invisibility into the fourth dimension - time - creating the groundbreaking potential to hide whole events.
More than 300 elementary, middle- and high-school students from throughout Tech Valley received a firsthand look at careers in the emerging field of nanotechnology when they visited the College of Nanoscale Science and Engineering of the University at Albany for NanoCareer Day on November 15.
