Metabolix Inc. (Cambridge, Mass.; www.metabolix.com) has successfully demonstrated and completed research and development for scaleup on a fermentation process that produces gamma -butyrolactone (GBL) from genetically engineered bacteria. The process is built upon the company’s technology for engineering metabolic pathways…
Since the isolation of graphene by the “Scotch tape” method, many researchers have tried to synthesize solution-dispersible graphene. The challenge has been to develop a high-yield method that can exfoliate graphite efficiently into solution-dispersible graphene sheets without collateral damage to…
Today only a few percent of Canada’s oil sands resource is accessible by traditional surface mining, so the rest has to be recovered in situ, mostly by steam-assisted gravity drainage (SAGD). In this process, steam is injected into a horizontal…
A new yeast strain that could one day substitute for petroleum as a source of surfactants for detergents, soaps and cosmetics has been identified by researchers at the U.S. Dept. of Agriculture’s National Center for Agricultural Utilization Research (Peoria, Ill.;…
BASF (Ludwigshafen, Germany; www.basf.com) announced this week that its catalyst division will begin a new round of capital investment projects to increase production capacity for copper and copper-chrome catalysts. These investments are aimed at improving catalyst manufacturing efficiency to meet…
A new anode material with nanostructured interfaces between barium oxide and nickel prevents deactivation by coking in solid-oxide fuel cells (SOFCs) using carbon-containing fuels. The material offers a path to low-cost, low-emission SOFCs that can convert gasified carbon fuels to…
Graphene from dry ice Researchers at Northern Illinois University (NIU; DeKalb, Ill.; www.niu.edu) discovered a new method for producing graphene that involves burning pure magnesium metal in dry ice. The method, which is capable of producing large quantities of…
The properties of gold nanoparticles could be combined with those of polydimethylsiloxane (PDMS) to provide a sustainable and practical solution for water treatment, according to a team from the Jawaharlal Nehru Center for Advanced Scientific Research (Bangalore, India; www.jncasr.ac.in). The…
This new tank-washing nozzle made from PTFE delivers a slow-moving, high-impact spray action against internal surfaces of tanks and vessels for effective removal of scum rings, or tougher residues. The HydroWhirl Poseidon tank-washing nozzle is especially suited to cleaning and…
This company has developed its CSR family of latent acid catalysts to create formulations suitable for production of stable phenolic and furan-based polymeric mixes with more than three months shelf-life at room temperature. These inherently flame-retardant bulk and sheet-molding compounds…
