Materials Sciences

University of Wisconsin-Madison researchers have demonstrated a way to release thin membranes of semiconductors from a substrate and transfer them to new surfaces-an advance that could unite the properties of silicon and many other materials, including diamond, metal and even plastic.

Led by materials science and engineering graduate student Michelle Roberts, the team reports in the April 9 issue of Nature Materials that the freed membranes, just tens of nanometers thick, retain

Using transparent zebrafish embryos, researchers at Jefferson Medical College in Philadelphia have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation. The nanoparticle, a soccer ball-shaped, hollow, carbon-based structure known as a fullerene, acts like an “oxygen sink,” binding to dangerous oxygen radicals produced by radiation.

The scientists, led by Adam P. Dicker, M.D., Ph.D., and Ulrich Rodeck, M.D., see fullerenes as a potentially “new

Textural properties as a function of the starting mineral particle size

Development of new clean technologies in accordance with increasingly demanding environmental legislation requires new catalysts, adsorbents and/or catalyst supports. Clays have been identified as a promising materials resource for this application.
More specifically, Pillared Inter-Layered Clays (PILCs) have been identified as suitable for these purposes. However, their widespread use has been delayed by d

Results essential to optimize materials for diverse applications

Steadily increasing the length of a purified conducting polymer vastly improves its ability to conduct electricity, report researchers at Carnegie Mellon University, whose work appeared March 22 in the Journal of the American Chemical Society. Their study of regioregular polythiophenes (RRPs) establishes benchmark properties for these materials that suggest how to optimize their use for a new generation of diverse mat

A Duke University engineer is “herding” tiny lenses with magnetic ferrofluids, precisely aligning them so that they focus bursts of light to excavate patterns of cavities on surfaces.

Such photolithographically produced “nanocavities” -– each only billionths of a meter across – might serve as repositories for molecules engineered as chemical detectors, said Benjamin Yellen, an assistant professor of mechanical engineering and materials science at Duke’s Pratt School of Engin

Mesoporous nanospheres focus of Ames Laboratory research

Delivering a dose of chemotherapy drugs to specific cancer cells without the risk of side affects to healthy cells may one day be possible thanks to a nanoscale drug delivery system being explored by researchers at the U.S. Department of Energy’s Ames Laboratory.

Using tiny silica particles call mesoporous nanospheres to carry drugs inside living cells, Ames Laboratory chemist Victor Lin is studying different metho
