At first glance, it seems as if billions of lead atoms have mysteriously disappeared. When exposed to heat, a layer of lead coated onto a nickel surface becomes almost invisible from one moment to the next. In reality, the slightest disturbance causes these atoms to suddenly switch from a broad "flat pancake" shape to a compact hemisphere.
Engineers in the CNST NanoFab have developed a new plasma etching technique for silicon which improves the etch rate, the mask selectivity, and the sidewall profile by optimizing the addition of argon to the process flow.
Researchers from TU Delft and VU University Amsterdam in the Netherlands have demonstrated that the size of a metal alloy nanoparticle influences the speed with which hydrogen gas is released when stored in a metal hydride. The smaller the size of the nanoparticle, the greater the speed at which the hydrogen gas makes its way to the fuel cell.
Auf der Tagung "Nanotechnologie in Forschung und Anwendung - Ein Update fuer Entscheider und Interessierte" der Aktionslinie Hessen-Nanotech des Hessischen Wirtschaftsministeriums wurde das Potenzial der Nanotechnologie fuer Fortschritt und Wirtschaft in Hessen deutlich.
Scientists have demonstrated a new way to decrease zinc oxide's thermal conductivity without reducing its electrical conductivity. The innovation involves adding minute amounts of aluminum to zinc oxide, and processing the materials in a microwave oven.
A team from the National University of Singapore's Nanoscience and Nanotechnology Initiative (NUSNNI), led by principle investigator Dr Xie Xian Ning, has developed the world's first energy-storage membrane.
ASM International will bestow its most prestigious honors upon 15 leaders in materials science and engineering at MS+T 2011, the Materials Science and Technology conference in Columbus, Ohio, on Oct. 18. The awards recognize lifetime achievement or breakthroughs in understanding and use of materials such as metals, ceramics, polymers and nanomaterials.
microTAS 2011 conference, the premier international event for reporting research in microfluidics, nanotechnology and detection technologies for life science and chemistry, University of Cincinnati researchers will present a simple, low-cost, method for separating and safely collecting concentrated volumes of fragile prostate cancer cells.
Physicists at the U.S. Department of Energy's Ames Laboratory are studying the interaction of materials that are promising for use in nanoscale electronics: graphene and different types of metals. The team has discovered the rare-earth metals dysprosium and gadolinium react strongly with graphene, while lead does not.
