Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. Rice University chemists have answered the call this week with a polymer-coated version of gold-platinum nanorods, the first catalysts of their kind that can be used in the organic solvents favored by chemical and drug manufacturers.
The purpose of the OECD Series on the Safety of Manufactured Nanomaterials is to provide up-to-date information on the diverse activities at OECD related to human health and environmental safety. The latest publications are available for download .
The National Science Foundation has awarded Clemson University researchers $2 million to study ways to mimic the suction mechanism used by butterflies and moths to feed so that the same method can be used in medical diagnostics.
Was Silizium fuer die Entwickler von Computerchips, ist fuer Laserphysiker eine Substanz namens Lithiumniobat. Diese Stellung verdanken die durchsichtigen Kristalle vor allem einer schoenen Eigenschaft: Sie koennen die Farbe von Laserlicht veraendern. Dazu muessen sie allerdings ausreichend sauber sein. Und diese Reinigung war bislang ein schwieriges und teures Unterfangen. Forscher um den Bonner Physiker Professor Dr. Karsten Buse konnten freien Elektronen nun mit einem Besen aus Licht aus dem Kristall kehren.
Pat Thiel, senior chemist at the U.S. Department of Energy?s Ames Laboratory, has been named the winner of the 2010 Arthur W. Adamson Award for Distinguished Service in the Advancement of Surface Chemistry.
The Human Enhancement Ethics Group today released a new report funded by the US National Science Foundation, addressing such topics as: definitions, possible scenarios, freedom and autonomy, fairness and equity, societal disruptions, human dignity, rights and obligations, and policy and law.
Researchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.
The panel is being convened as a result of discussions at a March meeting of the ANSI- NSP, where members identified nanomedicine as an industry sector where the U.S. should take the lead in development of nanotechnology standards.
The second, completely revised and enlarged edition of What is What in the Nanoworld summarizes the terms and definitions, most important phenomena, and regulations occurring in the physics, chemistry, technology, and application of nanostructures.
'10 ways to control rheology by changing particle properties' is the latest addition to Malvern Instruments' INFORM series of white papers, which are designed to provide advice on material characterization issues.
Chemists at the California Institute of Technology (Caltech) and The Scripps Research Institute (SRI) have developed an innovative technique to create cheap but highly stable chemicals that have the potential to take the place of the antibodies used in many standard medical diagnostic tests.
