The standard way to test for toxicity in individuals who have been exposed to heavy metals is to take a blood sample and analyze it in the laboratory by plasma mass spectrometry, an expensive and time-consuming procedure. Now, a portable…
Although nanoporous silica membranes are promising systems for the molecular separation of gases and liquids, they lack microstructural stability in the presence of water at temperatures as low as 60°C. Prolonged exposure to water causes hydrolysis, resulting in the formation…
Ateam of researchers at the U.S. Department of Energy’s Argonne National Laboratory (ANL, Argonne, Ill.; edlinks.chemengonline.com/7370-568) has developed a membrane capable of producing olefins from alkanes, and reducing wasted energy and pollutants while improving selectivity and yield. Steam cracking, or…
Flowserve Corp. (Dallas, Tex.; edlinks.chemengonline.com/7370-569) has introduced a new noise-attenuating valve-trim for gaseous applications, one that simultaneously lowers the device’s manufacturing costs while improving its noise reduction capabilities. Like prior noise-attenuation trim, Flowserve’s Valtek Stealth is designed to reduce the…
The behavior of many different phenomena can be modeled by systems of ordinary differential equations (ODEs), but most ODEs cannot be solved analytically, in which case an approximation to the solution is found by applying numerical integration methods. Dutch-sponsored mathematician…
Scientists at the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory (Chilton, Didcot, U.K.; edlinks.chemengonline.com/7370-573) have developed a laser-based method for the characterization of the bulk-chemical content of pharmaceutical capsules — without opening the capsules. In collaboration with researchers…
Researchers at the Fraunhofer Institute for Solar Energy Systems (ISE; Freiburg, Germany; edlinks.chemengonline.com/7370-575) have developed a solar-cell prototype that is semi-transparent, color-tunable and (thus far) resistant to weather degradation. A "classical Grätzel cell" according to Andreas Gombert head of Fraunhofer’s…
Scientists from the Center Biology at University College Dublin (Ireland; edlinks.chemengonline.com/7370-576) and the University of Bologna (Italy; edlinks.chemengonline.com/7370-577) have developed an enzymatic process that can be applied to the synthesis of chiral pharmaceutical intermediates. The researchers use an enzyme called…
A team of researchers from MIT’s (Cambridge, Mass.; edlinks.chemengonline.com/7369-540) chemical and mechanical engineering departments, in association with the U.S. Air Force Research Laboratory (Edwards Air Force Base, Calif.), has developed oil-repellent surfaces with likely separations and safety applications for the…
PCM (Paris, France; edlinks.chemengonline.com/7369-541) has introduced what is claimed to be the world’s first all-metal progressing cavity pump (PCP). PCM Vulcain is capable of pumping extremely hot (350°C) and viscous fluids, making it particularly suitable for the thermal recovery of…
