New Clues to Mechanism for "Colossal Resistance" Effects

Understanding could lead to lower-power, increased-memory data-storage devices

21-Aug-2007 - Experiments at the U.S. Department of Energy's Brookhaven National Laboratory shed new light on some materials' ability to dramatically change their electrical resistance in the presence of an external magnetic or electric field. Small changes in resistance underlie many electronic devices, ...

A new wrinkle in thin film science

Simple, inexpensive way to measure material properties could impact cosmetics, coating and nanoelectronic industries

09-Aug-2007 - A remarkably simple experiment devised by scientists yields important information about the mechanical properties of thin films - nanoscopically thin layers of material that are deposited onto a metal, ceramic or semiconductor base. The research results, funded by the National Science Foundation ...

Side-to-side shaking of nanoresonators throws off impurities

08-Aug-2007 - Tiny vibrating silicon resonators are of intense interest in nanotechnology circles for their potential ability to detect bacteria, viruses, DNA and other biological molecules. Cornell researchers have demonstrated a new way to make these resonators vibrate "in the plane" - that is, side to side ...

01-Aug-2007 - Scientists at the U.S. Department of Energy's Argonne National Laboratory have identified a new technique for cleansing contaminated water and potentially purifying hydrogen for use in fuel cells, thanks to the discovery of a innovative type of porous material. Argonne materials scientists Peter ...

The computer recognizes chemical structures

The Fraunhofer Institute SCAI and InfoChem cooperate in developing a new software tool for the automatic recognition of images representing chemical structures

27-Jul-2007 - Scientists at the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI) have developed software that is able to recognize images of chemical structures. The tool also re-builds the structures and converts them into a computer-readable format. In the future, this solution, "chemoCR", ...

23-Jul-2007 - QIAGEN N.V. has entered a strategic agreement with the Joint Center for Structural Genomics (JCSG), one of the 4 PSI Structural Genomics Production Centers, providing protein crystallographers with a new set of proven crystallization screens that have been assembled from analysis of hundreds of ...

Are nanoscale materials new or existing chemical substances

EPA Foregoes Opportunity to Improve Nanotechnology Oversight

17-Jul-2007 - The U.S. Environmental Protection Agency released its current thinking on whether a nanoscale material is a new or existing chemical substance under the Toxic Substances Control Act (TSCA). In the document, TSCA Inventory Status of Nanoscale Substances-General Approach, EPA states that it will ...

Chromium (VI) in leather clothing and shoes problematic for allergy sufferers

BfR recommends strictly limiting levels in leather goods

04-Jul-2007 - Studies by the regulatory authorities of the federal states reveal that many leather goods like gloves, shoes or watch straps which come into direct contact with the skin contain high levels of chromium (VI). Hexavalent chromium is a strong allergen and it can lead to allergic skin reactions like ...
