Chemists and engineers from the Performance Materials Segment of Evonik Industries AG (Essen, Germany; www.evonik.com) have developed a new process for making methyl methacrylate (MMA). With a yield of over 90%, the so-called Leading in Methacrylates (LiMA) process can be…
A triple-layer, porous membrane system developed at the Functional Materials Laboratory at Eidgenössische Technische Hochschule Zürich (www.fml.ethz.ch) can be fashioned into evaporative curtains to cool and humidify indoor spaces, potentially decreasing the energy demand for climate-control systems. Juxtaposing opposite forces…
NTT Communications Corp. (NTT Com; www.ntt.com) and Mitsui Chemicals Inc. (both Tokyo, Japan; www.mitsuichem.com) have demonstrated the ability to predict, with a high precision, the concentration of gaseous products generated in a furnace. The predictions are produced in just 20…
A newly patented class of synthetic antimicrobial compounds is aimed at overcoming the limitations of existing industrial disinfectants, such as quaternary ammonium compounds and bleaches. “Bleaches are effective disinfectants on initial application, but they don’t work when they dry and…
Silicon anodes are an attractive alternative to graphite anodes currently in use in lithium-ion batteries, because they can deliver up to five times higher capacities. However, silicon anodes have a limited charge-discharge cycle number. Their volume expands during each cycle,…
Soil bacteria that oxidize methane (methanotrophs) are important in capturing methane before it enters the atmosphere. Now an international team has isolated and characterized methanotrophic bacteria — obtained from a New Zealand volcanic field — that can grow on CH4…
Lithium Australia NL (Perth, Western Australia; lithium-au.com) has generated 99.8% (battery-grade) lithium carbonate from lithium-bearing silicates, such as spodumene, using its Sileach process — a hydrometallurgical process that does not require an energy-intensive roasting step. The company says Sileach has…
Graphene can be produced and isolated by exfoliating graphite, but existing processes are difficult and expensive. The most common method involves aggressive oxidation of graphite and results in diminished properties and added expense. Another approach — mechanical exfoliation — requires…
A new research partnership between the Water Environment & Reuse Foundation (WERF; Alexandria, Va.; www.werf.org) and the University of Texas at Arlington (UTA; www.uta.edu) seeks to tackle one of the most challenging and persistent water contaminants — perfluorooctane sulfonate (PFOS).…
JFE Steel Corp. (Tokyo, Japan; www.jfe-steel.co.jp) plans to build a pilot plant for using ferro coke in the ironmaking process at its Fukuyama area of West Japan Works, with support from the New Energy and Industrial Technology Development Organization (NEDO;…
