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…
Although polystyrene has been adopted into a large number of end products, it remains one of the least-recycled plastic waste streams — an estimated 95% of polystyrene materials are discarded after a single use. Employing a proprietary thermo-catalytic process, GreenMantra…
A newly developed aluminum-cerium alloy is exceptionally stable at high temperatures, and is highly corrosion-resistant, allowing its use in components for advanced engines and for other aerospace, automotive and power-generation applications. Co-developed by Eck Industries (Manitowoc, Wis.; www.eckindustries.com) and Oak…
A liquid metal membrane with liquid gallium (Ga) sandwiched between two porous silicon carbide supports offers a pathway to improve the currently available membranes of solid palladium (Pd) metal for separating hydrogen after the steam reforming of methane. Pd metal…
In critical pumping applications involving toxic or expensive products, the use of double mechanical seals or external flushing fluids can lead to product contamination or leakage, as well as additional costs for installation and monitoring. Although hermetically-sealed pumps, such as…
DPC monomer As part of an NEDO project, Asahi Kasei Corp. (Tokyo, Japan; www.asahi-kasei.co.jp) verified a newly developed process for diphenyl carbonate (DPC), a monomer used to produce polycarbonate (PC) at its Mizushima Works (Kurashiki, Okayama). The stability and operability…
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…
