Chementator: Sonopolymerization as a means to manufacture composite nanoparticles
Many methods have been developed for the encapsulation of "active" materials within a carrier nanoparticle, such as a polymer. These composite structures can be used in many biomedical, cosmetics, and food processing applications for the controlled release of pharmaceuticals, neutraceuticals,…
Reduce process consumables with this new separator
Aqueous Recovery Resources, Inc. (ARR; Bedford Hill, NY; www.suparator.com), has developed the Suparator, an oil/water separation system that involves no moving parts or media, for low operational costs and minimal maintenance. The separator (diagram) is based on the Bernoulli effect,…
Chementator: A less expensive way to make conductive coatings
Cambrios Technologies Corp. (Sunnyvale, Calif.; www.cambrios.com) has formed a strategic partnership with Chisso Corp. (www.chisso.co.jp) and Sumitomo Corp. (both Tokyo; www.sumitomocorp.co.jp) for commercialization of Cambrios’ first product, ClearOhm coating material. Targeted for the liquid crystal display (LCD) market, ClearOhm is…
Chementator: A new standard for viscosity measurement
The American Society of Testing Materials (Conshohocken, Pa.; www.astm.org) has developed a new standard for measuring viscosity: ASTM D 7483-08, Determination of Dynamic and Kinematic Viscosity of Liquids by Oscillating Piston Viscometer (OPV). The new ASTM method is part of…
Chementator: High-throughput screening accelerates glycerol-to-chemicals research
Arkema (Colomes, France; www.arkema.com) and hte (Heidelberg, Germany; www.hte-company.de) have successfully concluded a research collaboration aimed at identifying new catalysts for the conversion of glycerol — a byproduct of biodiesel production — to acrolein (2-propenal) and acrylic acid. The collaboration,…
Chementator: A palladium catalyst makes primary amines in aqueous NH3
Primary amines are made in high yield by a palladium-catalyzed allylic amination reaction developed by Shu Kobayashi, a chemistry professor at the University of Tokyo (Japan; www.chem.s.u-tokyo.ac.jp.). The reaction uses aqueous ammonia as the nitrogen source — the first time…
Chementator: Optical fiber sensing gets an NSF boost
Last January, Chiral Photonics, Inc. (Pine Brook, N.J.; www.chiralphotonics.com) was awarded $500,000 in a Small Business Technology Transfer Phase II grant from the National Science Foundation (NSF; Washington, D.C.). The grant will be used to develop a new optical-fiber-sensor platform…
Cut installation costs in half with this orifice flowmeter
ABB Instrumentation (Warminster, Pa.; www.abb.com/instrumentation) has cut the cost of installing orifice-plate flowmeters by up to half with the launch of its OriMaster compact orifice DP flowmeter. The latest in the company’s FlowMaster range, the OriMaster comes fully factory configured…
Chementator: EPA proposes national reporting system for greenhouse gases
The U.S. Environmental Protection Agency (EPA, Washington D.C.) plans to set up the first U.S. national system for reporting emissions of CO2 and other greenhouse gases. The proposal marks the first step toward a program for climate control. "Through this…
