. . . and from microorganisms
Last month, BP Corp. (London; www.bp.com) signed a joint-development agreement with Martek Biosciences Corp. (Columbia, Md.; www.martek.com) to work on the production of microbial oils for biofuels applications. The two companies aim to establish proof of concept for large-scale, cost-effective…
September Chementator briefs
Pharmaceuticals and agrochemicals often incorporate a fluorine atom within their molecular structure to improve properties, such as keeping the body from metabolizing a drug too rapidly. However, adding a fluorine to an aromatic ring at a late stage of the…
New heating technique improves zeolite membrane performance
Adding a rapid heat-treatment step to the process of making zeolite membranes improves separation performance by eliminating grain boundary defects, according to researchers from the University of Minnesota (UMN; Minneapolis, Minn.; www.umn.edu), who published their study in the July 31…
Pt-free catalysts promise to lower fuel-cell costs
Showa Denko K.K. (Tokyo; www.sdk.co.jp/html/english) has developed a platinum-substitute catalyst system for polymer electrolyte fuel cells (PEFCs) under the New Energy and Industrial Technology Development Organization’s (NEDO; Kawasaki, Japan) project led by professor Kenichiro Ota of Yokohama National University. The…
Reducing the Pt load promises to reduce PEFC costs
A technique for making PEFC electrodes with one fourth the amount of platinum catalyst compared to conventional PEFCs has been developed by Hosokawa Micron Corp. (Osaka, Japan; www.hosokawamicron.co.jp/en) in collaboration with professors Kiyoshi Kanamura, Tokyo Metropolitan University, and Makio Naitou,…
This process may produce electricity from low-temperature geothermal resources
The world has vast geothermal resources in the temperature range of 150–250°F, but these temperatures are too low for economical exploitation, using today’s technology. A process that could change the benchmark is being developed at Pacific Northwest National Laboratory (PNNL,…
Fast digestion makes better use of municipal sludge
The use of residual sludge from municipal sewage plants as fertilizer in agriculture is controversial (due to heavy metals and other pollutants), and slurry can no longer be disposed of in landfills in many countries. A less expensive alternative to…
An activated carbon for picking up heavy metals
The Agricultural Research Service (ARS, Beltsville, Md.; www.ars.usda.gov) has received a patent on a process for producing activated carbon from poultry litter, which consists of bedding materials such as sawdust and peanut shells, along with droppings and feathers. U.S.-grown broiler…
A cost-effective process for recycling wastewater
A wastewater treatment process that consumes less energy, produces less sludge and makes available up to 75% of the water for reuse — including that of potable water quality — has been commercialized by Linde Gases, a division of The…
A protective coating helps fine powders flow, without agglomeration
A team from Monash Institute of Pharmaceutical Science at Monash University (Melbourne, Australia; www.pharm.monash.edu.au), has developed an approach — a hybrid mixing and milling process — for producing fine (1–20 µm) pharmaceutical powders with good flow and de-agglomeration properties. Team…
