With the exception of Oslo-type crystallizers, the main commercial crystallizers are agitated systems that use an agitator [agitated tank or draft-tube baffle (DTB)] or a circulation pump [forced circulation (FC) crystallizers]. In such systems, however, large crystals become damaged by…
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,…
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,…
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…
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…
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,…
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…
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…
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…
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…
