Much like a meteor impacting a planet, highly charged ions hit really hard and can do a lot of damage, albeit on a much smaller scale. And much like geologists determine the size and speed of the meteor by looking at the hole it left, physicists can learn a lot about a highly charged ion's energy by looking at the divots it makes in thin films.
Solar or photovoltaic cells represent one of the best possible technologies for providing an absolutely clean and virtually inexhaustible source of energy to power our civilization. However, for this dream to be realized, solar cells need to be made from inexpensive elements using low-cost, less energy-intensive processing chemistry, and they need to efficiently and cost-competitively convert sunlight into electricity. A team of researchers with the Lawrence Berkeley National Laboratory has now demonstrated two out of three of these requirements with a promising start on the third.
Researchers at RIKEN have developed a ground-breaking new aqueous reagent which literally turns biological tissue transparent. Experiments using fluorescence microscopy on samples treated with the reagent have produced vivid 3D images of neurons and blood vessels deep inside the mouse brain.
The rapid detection of microRNAs using small-volume samples could therefore help save millions of lives. Such a technique could also pave the way for widespread analysis of the spatial and temporal patterns of gene activity involving microRNAs, which are believed to play a critical role in the development and operation of organisms.
Researchers at NIST significantly extended the reach of their novel microfluidic system for analyzing the chemical components of complex samples. The new work shows how the system, meant to analyze real-world, crude mixtures such as dirt or whole blood, can work for negatively charged components as well as it has in the past for positively charged ones.
With a nod to biology, scientists at the National Institute of Standards and Technology (NIST) have a new approach to the problem of safely storing hydrogen in future fuel-cell-powered cars. Their idea: molecular scale 'veins' of iron permeating grains of magnesium like a network of capillaries.
At today's second annual Global Technology Conference (GTC 2011), GLOBALFOUNDRIES announced the winners of its new "Leading in Innovation" awards. Presented to customers who have demonstrated innovative solutions on products ranging from 0.35um non-volatile memories to leading-edge 28nm smartphone processors, the awards showcase the company's collaborative approach to enabling chip designers to deliver a superior end-user experience.
To support Office of Naval Research (ONR) development of hydrodynamically efficient and environmentally non-toxic anti-corrosion materials, Dr. Chang-Hwan Choi, Assistant Professor of Mechanical Engineering at Stevens Institute of Technology, researches nanotechnology with multifunctional superhydrophobic properties that repel water and prevent corrosion in robust and durable ways. Dr. Choi's work has recently been awarded a Defense University Research Instrumentation Program (DURIP) grant that backs this work.
This conference will present the first systematic and comprehensive recommendations and analysis on protecting human participants in research on nanomedicine products, including drugs, devices, and gene therapy using nano-vectors.
A collaboration between the Universities of Manchester and Cambridge, which includes Nobel Prize winning scientists Professor Andre Geim and Professor Kostya Novoselov, has discovered a crucial recipe for improving characteristics of graphene devices for use as photodetectors in future high-speed optical communications.
