Researchers of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, used a calcium ion to simulate a relativistic quantum particle, demonstrating a phenomenon that has not been directly observable so far: the Zitterbewegung. They have published their findings in the current issue of the journal Nature.
Real-time monitoring of high-density polyethylene (HDPE) production is now possible. In an article in the journal Macromolecular Reaction Engineering, Professor Rolf Mülhaupt and his student Rainer Xalter of Albert-Ludwigs University in Freiburg, Germany, describe how they use a combination of laser reflectance measurements and video monitoring to follow the polymerization of ethylene in slurries in standard commercial-scale reactors.
Transforming lead into gold is an impossible feat, but a similar type of "alchemy" is not only possible, but cost-effective too. Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements.
A Virginia Tech physicist is one of three faculty members from the College of Science who have been awarded prestigious Faculty Early Career Development (CAREER) grants by the National Science Foundation (NSF).
Symyx Technologies, Inc. and the Royal Society of Chemistry (RSC) have announced the launch of a collaborative partnership designed to enhance the usability and accessibility of public scientific databases. The first joi...
Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but theoreticians at the Joint Quantum Institute (JQI) , a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, and their colleagues in India and the George Mason University, now believe that there may be a new kind of soliton that's even more special.
Nanotechnology seems a daunting subject, but for mechanical engineering students at the University of Nevada, Reno, it has taken on a real world approach - in Ski Building 101.
University of Toronto quantum optics researchers Sajeev John and Xun Ma have discovered new behaviours of light within photonic crystals that could lead to faster optical information processing and compact computers that...
Kobe Steel, Ltd. announces that it is providing Austria's voestalpine Stahl GmbH, with technology to produce fingerprint-resistant electrogalvanized steel sheet.
This material is highly applicable for use in appl...
Scientists at the U.S. Department of Energy's Argonne National Laboratory have discovered the microscopic mechanism behind the phenomenon of superinsulation, the ability of certain materials to completely block the flow of electric current at low temperatures. The essence of the mechanism is what the authors termed "multi-stage energy relaxation."
