Make nanoparticles while the sun shines
rsc.org January 8th, 2008 Concentrated sunlight is all you need to make useful nanomaterials, according to Israeli researchers. Jeffrey Gordon of Ben-Gurion University in the Negev desert, Reshef Tenne of the Weizmann Institute, Rehovot, and their collaborators collect solar radiation outdoors and transmit it to an indoor laboratory with optical fibres. Here it is focussed on molybdenum sulfide or quartz powders, transforming them into nanotubes and nanocages. This is the first time that silica nanofibres and nanospheres have been produced from pure quartz, they said. Wolfgang Tremel, who works on inorganic nanoparticles at the University of Mainz in Germany explained 'A particular problem in the synthesis of fullerene-type nanoparticles and nanotubes is that high temperatures are needed to interconnect the edges of fragments in such a way as to provide curvature to otherwise flat slabs.'

Nanotechnology innovation may revolutionize gene detection in a single cell
Arizona State University January 10th, 2008 Scientists at Arizona State University's Biodesign Institute have developed the world's first gene detection platform made up entirely from self-assembled DNA nanostructures. The results, appearing in the January 11 issue of the journal Science, could have broad implications for gene chip technology and may also revolutionize the way in which gene expression is analyzed in a single cell.

Feeling the Heat: Berkeley Researchers Make Thermoelectric Breakthrough in Silicon Nanowires
Berkeley Lab January 10th, 2008 Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley. The far-ranging potential applications of this technology include DOE's hydrogen fuel cell-powered "Freedom CAR," and personal power-jackets that could use heat from the human body to recharge cell-phones and other electronic devices.

U of M researcher helps discover road to sustainable electronic devices
University of Minnesota January 10th, 2008 A recent discovery by a multinational team including a University of Minnesota scientist, professor Michael Sadowsky in the department of soil, water and climate, could lead to more environmentally friendly manufacturing of electronic devices.
