Sun 9 Aug 2009 Chemical Separations: Membrane Breaks Through Performance Barrier. Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates.more

Thu 6 Aug 2009 All-in-One Nanoparticle: A 'Swiss Army Knife' For Nanomedicine. Nanoparticles are being developed to perform a wide range of medical uses -- imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.more

Tue 21 July 2009 GridCOMP: A Software To Unlock The Power Of Grids — A huge amount of computing power sits idle most of the time, and new technologies enabling the sharing of resources aim to capitalise on that. Now European researchers have developed software to simultaneously run applications on very different IT infrastructures http://gridcomp.ercim.org/content/view/60/43/ .more

Mon 20 July 2009 Controlling The Electronic Surface Properties Of A Material. It's commonly accepted that electrical resistance of a given material cannot be adjusted as is the case with, for example, density and color. However, researchers from PSI, Switzerland have now succeeded in developing a new method to selectively tune surface properties such as resistance.more

Sun 19 July 2009 New Geothermal Heat Extraction Process To Deliver Clean Power Generation. A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy's Pacific Northwest National Laboratory will determine if their innovative approach can safely and economically extract and convert heat from vast untapped geothermal resources.more

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 fأ¼r 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
