Mon 13 Jul 2009 Researchers Find A Quicker, Cheaper Way To Sort Isotopes. Whether it's the summer grass that tickles your feet or the red Bordeaux smacking on your palette, nearly every part of the world around you carries special chemical markers. These markers, called isotopes, can tell scientists where the molecules that compose a substance are from, where they traveled, and what happened to them along the way. But doing these analyses has been complex and costly. Now, Stanford chemists have developed a new method to make isotopic analysis easier and less expensive.more

Sun 28Jun 2009 Scientists at the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago have reached a milestone in the study of emergent magnetism. Studying simple metallic chromium, the joint UChicago-Argonne team discovered a pressure-driven quantum critical regime and achieved the first direct measurement of a "naked" quantum singularity in an elemental magnet.more

Sun 14 June 2009, New Chemical Element In The Periodic Table. The element 112, discovered at the GSI Helmholtzzentrum für Schwerionenforschung (Centre for Heavy Ion Research) in Darmstadt, has been officially recognized as a new element by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC confirmed the recognition of element 112 in an official letter to the head of the discovering team, Professor Sigurd Hofmann. The letter furthermore asks the discoverers to propose a name for the new element.more

Tue 2 Jun 2009, Regular Light Bulbs Made Super-efficient With Ultra-fast Laser. An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.more

Mon 1 June 2009, Interferometer Gets More Quiet Mirrors — In physics many subtle phenomena can be studied by allowing waves to interfere with each other. In an interferometer, light waves travel by two different paths, directed from place to place by strategically places mirrors, and converge at a detector, where they produce a striped interference pattern.more

Mon 18 May 2009, Enabling Graphene-based Technology Via Chemical Functionalization. Graphene is an atomically thin sheet of carbon that has attracted significant attention due to its potential use in high-performance electronics, sensors and alternative energy devices such as solar cells. While the physics of graphene has been thoroughly explored, chemical functionalization of graphene has proven to be elusive. more

Sun, 15 Mar 2009 An international team of scientists have discovered a transparent form of the element sodium (Na). The team, led by Artem Oganov, Professor of Theoretical Crystallography at Stony Brook University, and Yanming Ma, the lead author and professor of physics at Jilin University in China, was able to demonstrate that sodium defies normal physical expectations by going transparent under pressure. more?
