Organomagnesium compounds have become a highly important class of reagents in organic chemistry since the discovery of the Grignard Reaction more than 100 years ago. These compounds are powerful and inexpensive reagents that can be readily prepared from metallic magnesium…
Scientists at the California Institute of Technology’s Joint Center for Artificial Photosynthesis (Caltech JCAP; Pasadena, Calif.; www.caltech.edu) have reported the first system for generating hydrogen gas from water using solar energy that simultaneously achieves high efficiency and oxidative stability along…
Li-S Battery Storage Anesco Ltd. (Reading, U.K.; www.anesco.co.uk) and OXIS Energy (Abingdon, U.K.; www.oxisenergy.com) have begun a collaboration to commercialize OXIS Lithium Sulfur Technology for battery storage for commercial and residential renewable installations. The new battery storage units will be…
Japanese companies INPEX Corp. (Tokyo, www.inpex.co.jp), Chiyoda Corp. (Yokohama; www.chiyoda-corp.com), and Metawater Co., Ltd. (Tokyo, all Japan; www.metawater.co.jp) have been commissioned to build a small-scale demonstration facility that will use ceramic membrane filtration for treating produced water for Japan Oil,…
During casting of aluminum alloys, degassing is required to remove hydrogen from the molten metal in order to prevent porosity in the solid metal that deteriorates its properties and performance. Currently, the so-called argon rotary degassing is used, where a…
A new technology for treating cooling tower water is designed to control scale formation and provide corrosion protection without using phosphorus-containing compounds. Phosphorus from wastewater discharge is known to be a major factor in fueling algae blooms and excessive aquatic…
Currently, the active components of most pharmaceuticals and fine chemicals are synthesized by multiple batch reactions, in which all starting materials are mixed in reaction vessels and the desired compounds are extracted and purified after each reaction has finished. Such…
Last month, Johnson Matthey Process Technologies (JMPT; London, U.K.; www.matthey.com) and Rennovia Inc. (Santa Clara, Calif.; www.rennovia.com) successfully started-up a fully integrated mini-plant for production of glucaric acid from glucose using jointly developed technology. The mini-plant is located at the…
It has been known for a long time that sulfonated active-carbon acid can catalyze both esterification and transesterification to produce biodiesel fuels from oils with high acid value without pretreatment. However, the separation of such catalysts requires filtration or centrifugation,…
Micropollutants, such as antibiotics and flame retardants, can pose a health threat to animals and humans, even in tiny concentrations. Current methods to remove micropollutants from the environment include adsorption onto powdered activated carbon, which is then separated from the…
