Although theoretically promising 80% more energy than is required to grow and convert to cellulosic ethanol, switchgrass has proven to be a difficult fuel source to break down cost effectively. With $1 million from the U.S. Depts. of Agriculture (USDA)…
Sugar-beet processors in the U.S. generate approximately 40 million tons of fiber-rich sugar-beet pulp every year as a byproduct of sucrose extraction. Most of it is used as livestock feed or in pet food. Researchers with the U.S. Agricultural Research…
In cooperation with several universities, Clariant International Ltd. (Muttenz, Switzerland; edlinks.chemengonline.com/7371-543) has developed a process to manufacture high-quality nano-sized zeolite L (Linde Type L) in technical quantities. This new range of nano-scale aluminosilicates, tradenamed Lucidot, open up a new range…
A new nanomaterial which doubles as a filter and a reactor capable of destroying unwanted substances, has been developed by a team from Nanyang Technological University (NTU; Singapore; edlinks.chemengonline.com/7371-544), and the Singapore Public Utilities Board. The material consists of nanosized…
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…
