An international research team has simplified the steps to create highly efficient silicon solar cells by applying a new mix of materials to a standard design. Arrays of solar cells are used in solar panels to convert sunlight to electricity. The special blend of materials--which could also prove ...
A group of researchers in Japan and China identified the requirements for the development of new types of extremely low power consumption electric devices by studying Cr-doped (Sb, Bi)2Te3 thin films. At extremely low temperatures, an electric current flows around the edge of the film without ...
In the production of power, nearly two-thirds of energy input from fossil fuels is lost as waste heat. Industry is hungry for materials that can convert this heat to useful electricity, but a good thermoelectric material is hard to find. Increasing the efficiency of thermoelectric materials is ...
Highly-effective unknown doping agents have emerged; cannot be tested
A few days before the opening of the Winter Olympics in Sochi, WDR research has revealed serious doubts about a credible anti-doping campaign in the Olympics' host country. In the ARD Sports Show and the WDR broadcast "Sport Inside", WDR reporters cover encounters of a Russian scientist with ...
Rice University lab finds table sugar, metallic sheets produce pristine graphene in one step
Future computers may run a little sweeter, thanks to a refinement in the manufacture of graphene at Rice University. Rice researchers have learned to make pristine sheets of graphene, the one-atom-thick form of carbon, from plain table sugar and other carbon-based substances. They do so in a ...
The change-over to lead-free products is in full progress. The problem is however that the environmentally friendly alternatives have to be as effi cient as the lead-containing variants. One example is the injection system of diesel engines. Lead-free functional materials can be found faster by ...
Materials for tomorrow's nanoelectronics
In the recent issue of Nature, scientists from Empa and the Max Planck Institute for Polymer Research report how they have managed for the first time to grow graphene ribbons that are just a few nanometres wide using a simple surface-based chemical method. Graphene ribbons are considered to be ...
Rice researchers' method untangles long tubes, clears hurdle toward armchair quantum wire
Rice University scientists have found the "ultimate" solvent for all kinds of carbon nanotubes (CNTs), a breakthrough that brings the creation of a highly conductive quantum nanowire ever closer. Nanotubes have the frustrating habit of bundling, making them less useful than when they're ...
Agilent Technologies Inc. announced it has been selected by the South African Doping Control Laboratory as the primary provider of gas-phase testing instruments for the 2010 World Cup. The South African Doping Control Laboratory is certified by the World Anti-Doping Agency and will be responsible ...
New graphene-based electronics could take a page out of the silicon electronics book
An organic molecule that has been found to be effective in making silicon-based electronics may be viable for building electronics on sheets of carbon only a single molecule thick. Researchers at the Max Plank Institute for Metals Research in Stuttgart report the advance in a paper appearing ...
