University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill.
From balloons to rubber bands, things always break faster when stretched. Or do they? University of Illinois scientists studying chemical bonds now have shown this isn't always the case, and their results may have profound implications for the stability of proteins to mechanical stress and the design of new high-tech polymers.
A new National Institute of Standards and Technology assay using a 'glow or no glow' technique may soon help the U.S. Department of Homeland Security (DHS) defend the nation against a spectrum of biological weapons that could be used in a terrorist attack.
The SOI Industry Consortium, an international group aimed at accelerating broad adoption of silicon-on-insulator (SOI) materials technology across semiconductor markets, announced today that it is reinforcing its academic and research support with the additions of three prestigious universities at the forefront of SOI applied research.
When light propagates through multiple scattering media such as clouds, white paint, or nano-photonic devices, classical information for example the direction of propagation tends to be lost. Surprisingly this turns out to be different for quantum light.
The flow of water into and out from the cell may play a crucial role in several types of cancer. Scientists at the University of Gothenburg, Sweden, have now found the gate that regulates the flow of water into yeast cells.
The Rice University-based International Council on Nanotechnology (ICON) has introduced an interactive feature to its Virtual Journal of Nanotechnology Environment, Health and Safety that allows users to post ratings and comments about technical papers archived at the site.
It was an idea born out of curiosity in the physics lab, but now a new type of ?laser? for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology.
Zur NRW Nano-Konferenz vom 22. bis 23. Juni in Dortmund bringt IVAM Research das Kompendium 'Energie und Effizienz' heraus, in dem Unternehmen und Institute ihre Leistungen im Bereich 'Green Technologies' vorstellen.
Over the past year experts from the London School of Economics, Environmental Law Institute, Chatham House and the Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars have been examining issues of transatlantic regulatory cooperation. Their research findings are to be published in a major report, which will be launched at an international conference on 10-11 September 2009 in London.
Für die kleinsten Lampen der Welt gibt es jetzt gleich zwei neue Bauanleitungen. Nach diesen Plänen haben Wissenschaftler des Max-Planck-Instituts für Kolloid- und Grenzflächenforschung Nanopartikel maßgeschneidert, die als Positionsleuchten an Zellproteinen, künftig vielleicht aber auch als Lichtquellen für Bildschirme oder für die optische Informationstechnik dienen könnten.
Researchers at the National Institute of Standards and Technology (NIST) have discovered that a reduction in mechanical strain at the boundaries of crystal grains can significantly improve the performance of high-temperature superconductors.
The National Institute of Standards and Technology will be serving up 'soccer under glass' - the glass of a microscope lens - when nanosoccer makes its second appearance at the RoboCup games at the international competition in Graz, Austria, from June 29 to July 5, 2009.
Better predictions of how many valuable materials behave under stress could be on the way from the National Institute of Standards and Technology (NIST), where scientists have recently found evidence of an important similarity between the behavior of polycrystalline materials - such as metals and ceramics - and glasses
