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…
Fuel cells and hydrogen economy are inevitably used in the same breath when talking about clean power and ways to wean us from our addiction to carbon-based fuels. That’s because H2 -based fuel cells make electricity and heat with only…
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…
Synfuels International, Inc. (Dallas, Tex.; edlinks.chemengonline.com/7370-561) plans to commercialize its patented gas-to-liquids (GTL) process in Kuwait through a newly formed partnership with Kuwait’s Aref Energy Holding (edlinks.chemengonline.com/7370-562). In contrast with Fischer-Tropsch technology, the process produces a high-octane gasoline blend, rather…
Next month, Taiyo Kagaku Co. (Yokkaichi, Japan; edlinks.chemengonline.com/7370-563) will start up a 20-m.t./yr plant — said to be the world’s first — for the production of mesoporous silica. Taiyo Kagaku developed the new production process based on technology first introduced…
Alstom Power, Inc. (Windsor, Conn.; edlinks.chemengonline.com/7370-571) and The Dow Chemical Co. (Midland, Mich.; edlinks.chemengonline.com/7370-572) have established a joint development and commercialization agreement for advanced amine scrubbing technology for the removal of carbon dioxide from low-pressure fluegases of fossil-fuel-fired power plants…
