Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate - neither gain...
As if building a computer out of rubidium atoms and laser beams weren't difficult enough, scientists sometimes have to work as if blindfolded: The quirks of quantum physics can cause correlations between the atoms to...
A University of Arkansas physics professor and his colleagues have created a nanoscale structure that contains both magnetic and superconducting properties at the same time, and they will be exploring the properties of t...
A team of researchers from Rensselaer Polytechnic Institute has created the world’s first material that reflects virtually no light. Reporting in the March issue of Nature Photonics, they describe an optical coating made...
Arrowhead Research Corporation announced today that its majority-owned subsidiary, Aonex Technologies, Inc. has entered into a collaborative agreement with Kyma Technologies, Inc., a producer and marketer of semiconducto...
A recent upgrade at the Obourg (Belgium) facility of Holcim, one of the world’s leading cement producers, has seen the production plant move to an automated laboratory for the routine analysis of cement composition...
Showa Denko K.K. (SDK) has developed a new process for making high-quality compound semiconductors based on gallium nitride (GaN) and other nitrides to meet growing demand mainly for use in blue/white LEDs. The new proce...
In the world of cutting-edge physics, discoveries are often made using intricate procedures and elaborate, expensive instruments. But a paper by Cornell graduate student Scott Bunch and colleagues shows how interesting r...
When excited, atoms move at impossibly small length and time scales -- too small and too fast to have been observed in years past.
But as applied and engineering physics professor Joel D. Brock comments in the Feb. 2...
Stanford physicist Mark Kasevich has adapted the technology in today's airplane navigation systems to work with atoms so cold that they almost stand still. At temperatures scarcely above absolute zero, atoms no longe...
