(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
