Simulations of chemical processes that involve many reactants with continually changing compositions can be set up and run in minutes, rather than the previously required hours, with a newly commercialized software package, Reaction Engineering Lab, says developer Comsol (Stockholm, Sweden, and Burlington, Mass.; edlinks.che.com/5827-539). For reactions taking place in well-mixed systems or in tubular...

Archer Daniels Midland Co. (Decatur, Ill.; edlinks.com/5827-542) plans to build the world’s first commercial plant to produce PHA (polyhydroxyalkanoates), which are high-performance plastics made from renewable resources, such as corn sugar. The plant, to be located at a major ADM site in North America, will have an initial capacity of 50,000 m.t./yr. The facility is a joint venture being established...

Haldor Topsøe (Lyngby, Denmark; edlinks.che.com/5826-533) has introduced two new hydroprocessing catalysts, which are based on its proprietary BRIM technology. Both catalysts are nickel-molybdenum types that optimize both hydrogenation at so-called brim sites (situated on the basal-plane of the catalyst) and the Type II active sites (edge sites) for direct...

A single-step process for making phenol from benzene and carbon monoxide has been developed by Daicel Chemical Industries, Ltd. (Tokyo; edlinks.che.com/5826-543) with cooperation from Yasutaka Ishii, professor of applied chemistry at Kansai University (Osaka, Japan; edlinks.che.com/5826-544). Other attempts to make phenol directly, such as the reaction of benzene with hydrogen and oxygen over a...

Large tracts of land that have been used for military training, especially in the U.S., are contaminated with RDX— a widely used explosive that is both toxic and carcinogenic. Although bacteria have been isolated that can biodegrade the RDX, the degredation rates are too slow, allowing the RDX to leatch...

Using lithium metal as the anode of secondary Li-ion batteries would double the energy density of conventional batteries, which use anodes based on carbon. However, Li-based anodes suffer from the problem of dendrite crystal formation during the charge and discharge cycles of the battery. The needlelike projections of these dendrite crystals can result in short...

Last month, “Series C” funding in the plastic-electronics development company, Plastic Logic Ltd. (Cambridge, U.K.; edlinks.che.com/5825-537), reached $24 million, with the addition of investments from four new companies, including BASF Venture Capital GmbH (Ludwigshafen, Germany; edlinks.che.com/5825-538). Other companies that have previously invested in the firm include Dow Chemical (Midland...
