Engineers at the University of Wisconsin-Milwaukee have identified a catalyst that provides the same level of efficiency in microbial fuel cells as the currently used platinum catalyst, but at 5% of the cost.
Carl Zeiss Microscopy, a company of the Carl Zeiss Group and leading provider of light, laser-scanning and electron and ion beam microscopes, announces its 2012 'ZEISS on Your Campus' traveling tour, bringing free workshops designed to educate scientists and their students in the fundamentals of various microscopy techniques to universities across the country.
GAO recommends that the Director of the Office of Science and Technology Policy (OSTP), which administers the NSTC, (1) coordinate development of performance information for NNI EHS research needs and publicly report this information; and (2) estimate the costs and resources necessary to meet the research needs. OSTP and the seven included agencies neither agreed nor disagreed with the recommendations.
Scientists have, for the first time, trapped and confined light in graphene, an achievement which constitutes the most promising candidacy to process optic information at nanometric scales and which could open the door to a new generation of nano-sensors with applications in medicine, energy and computing.
Memory devices for computers require a large collection of components that can switch between two states, which represent the 1's and 0's of binary language. Engineers hope to make next-generation chips with materials that distinguish between these states by physically rearranging their atoms into different phases. Researchers at the University of Pennsylvania have now provided new insight into how this phase change happens, which could help engineers make memory storage devices faster and more efficient.
Researchers working at the National Institute of Standards and Technology (NIST) and the University of Maryland have shown that subjecting graphene to mechanical strain can mimic the effects of magnetic fields and create a quantum dot, an exotic type of semiconductor with a wide range of potential uses in electronic devices.
In a new study, Brown University engineers report that when they used selenium nanoparticles to coat polycarbonate, the material of catheters and endotracheal tubes, the results were significant reductions in cultured populations of Staphylococcus aureus bacteria, sometimes by as much as 90 percent.
Researchers have introduced a particularly clever biosensor concept: print on one side of the paper, fold it up origami-style, laminate it, and the test is ready. Test evaluation requires only a voltmeter.
