Any child can tell you that a magnet has a “north” and a “south” pole, and that if you break it into two pieces, you invariably get two smaller magnets with two poles of their own. But scientists have spent the better part of the last eight decades trying to find, in essence, a magnet with only one pole. A team working at the National Institute of Standards and Technology (NIST) has found one.
Silicon, the most important semiconductor material of all, is usually considered to be as brittle and breakable as window glass. On the nanometer scale, however, the substance exhibits very different properties, as Empa researchers have shown by creating minute silicon pillars.
NanoSight, manufacturers of unique nanoparticle characterization technology, is pleased to report that the School of Chemical Engineering at the University of Birmingham is using multiple NanoSight nanoparticle characterization systems to study viruses and catalyst nanoparticles.
Wires with atomic dimensions are potential structural elements for future nanoscopic electronic components. Such fine wires have completely new electronic properties. However, apart from the non-trivial production of metallic nanowires, their high chemical reactivity is a critical problem; they are easily oxidized in air and are not stable. Japanese researchers working with R. Kitaura and H. Shinohara have now developed a new method that is simple and delivers stable nanowires.
Oxford Instruments is delighted to have received further orders from the newly built King Abdullah University of Science and Technology (KAUST) in Saudi Arabia, which was inaugurated on 23 September by King Abdullah. These orders are for an Ionfab300 Plus, ion beam etch tool, and a second FlexAL® atomic layer deposition tool, bringing the number of systems ordered from Oxford Instruments to thirteen in total.
Calculations at the Max Planck Institute for Nuclear Physics and the Vienna University of Technology (Institute for Theoretical Physics) have now shown that high-energy heavy ion collisions at large particle accelerators are suitable as light sources for the desired single and double pulses. This is due to the remarkable properties of quark-gluon plasmas.
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize 2009 in Physics for two scientific achievements that have helped to shape the foundations of today's networked societies. It has been awarded...
A new ceramic material described in this week’s issue of the journal Science could help expand the applications for solid oxide fuel cells – devices that generate electricity directly from a wide range of liquid or gaseous fuels without the need to separate hydrogen.
Mercury pollution is a persistent problem in the environment. Human activity has lead to increasingly large accumulations of the toxic chemical, especially in waterways, where fish and shellfish tend to act as sponges fo...
The Information Storage Consortium has awarded its 2009 Technical Achievement Award to Jeffrey Pyun, UA assistant professor of chemistry, for pioneering research that improves materials for magnetic tape used for long-term archival storage.
