(PhysOrg.com) -- Soman, Tabun, and Sarin (which has already been used in terrorist attacks) are chemical weapons that attack the nervous system. When inhaled, these extremely toxic organophosphates can lead to death within minutes. The search for fast, simple detection methods for these colorless and odorless gases, which are unfortunately relatively easily manufactured, is correspondingly urgent. http://www.physorg.com/news172316206.html Chemistry Wed, 16 Sep 2009 10:37:54 EST news172316206 (PhysOrg.com) -- Don't be fooled by the collection of empty soda bottles in James Cryan's office at SLAC National Accelerator Laboratory. Cryan isn't a caffeine fiend -the cola bottles are for science. As a graduate student with the PULSE Institute for Ultrafast Energy Science, he is studying how nitrogen gas responds to stimulation by an optical laser, and he needed a container for the gas. Instead of ordering a cell and waiting for it to arrive, Cryan cast about for something close at hand -and happened upon one of the empty Coke bottles on his desk. http://www.physorg.com/news159123961.html Physics Thu, 16 Apr 2009 18:06:43 EST news159123961 (PhysOrg.com) -- A future sensor may take away a patient's breath while simultaneously determining whether the patient has breast cancer, lung cancer, diabetes or asthma. A University of Missouri researcher is developing a device that will analyze breath or urine samples for volatile markers inside the body that indicate disease. These volatile markers, such as alkanes, acetones or nitric oxide, give doctors clues about what is happening inside the body and can be used as a diagnostic tool. http://www.physorg.com/news155938204.html Chemistry Tue, 10 Mar 2009 21:10:27 EST news155938204 (PhysOrg.com) -- President Barack Obama's pursuit of energy independence promises to accelerate research and development for alternative energy sources -- solar, wind and geothermal power, biofuels, hydrogen and biomass, to name a few. http://www.physorg.com/news153928167.html Chemistry Sun, 15 Feb 2009 13:50:23 EST news153928167 A recent discovery at Case Western Reserve University may help keep food and drugs safer and fresher longer and electronic equipment dryer and more secure than ever before - all at a lower cost. http://www.physorg.com/news153144756.html Nanotechnology Fri, 06 Feb 2009 12:13:15 EST news153144756 (PhysOrg.com) -- Scientists have discovered that a type of hard mineral called zeolite can provide a high rate of gas flow in a micro-scale gas pump. Because the pump is based simply on temperature differences and has no moving parts, it could provide reliable and precise control of gas flow for a variety of applications, such as gas-sensing breath analyzers and warfare agent detectors. http://www.physorg.com/news147094299.html Physics Fri, 28 Nov 2008 11:31:39 EST news147094299
