Electron microscopes cannot be used to image living cells because the electrons destroy the samples. Now, MIT assistant professor Mehmet Fatih Yanik and his student, William Putnam, propose a new scheme that can overcome this limitation by using a quantum mechanical measurement technique that allows electrons to sense objects remotely.
Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix.
A UT Dallas researcher envisions a time soon when plastic sheets of solar cells are inexpensively stamped out in factories and then affixed to cell phones, laptops and other power-hungry mobile devices.
IMEC has demonstrated a fully solution-processed organic solar cell with a spray-coated active layer and a metal top contact spray-coated on top. The resulting cell shows power conversion efficiencies above 3%, a performance comparable to organic solar cells produced by spin coating of the organic layer and vacuum evaporation of the top contact metal.
IMEC, one of the leading European research centers in photovoltaics, and BP Solar, a leading energy company, demonstrated a 18% conversion efficiency for silicon solar cells made of BP Solar's newly developed Mono2 silicon.
In the battle against resistant microbes, a team at the University of Muenster (Germany) is now pursuing a new approach involving photodynamic therapy, which is a technique that is already being used in the treatment of certain forms of cancer and macular degeneration.
CIC biomaGUNE, the Centre for Cooperative Research in Biomaterials, is to lead the European project HINAMOX, an acronym that stands for Health Impact of Engineered Metal and Metal Oxide Nanoparticles: Response, Bioimaging and Distribution at Cellular and Body Level.
Researchers have developed a new method for studying bacterial swimming, one that allows them to trap Escherichia coli bacteria and modify the microbes' environment without hindering the way they move.
