Composite coating A new composite material that prevents metal corrosion, even under extreme conditions, has been developed by researchers from the INM – Leibniz Institute for New Materials GmbH (Germany; www.inm-gmbh.de). The patented composite consists of layers of particles placed…
A new prototype lithium battery with a very thin metal anode achieves an energy density of 1,200 W-h/L at room temperature — double that of conventional Li-ion batteries using graphite anodes. The prototype battery, developed by Massachusetts Institute of Technologys…
The New Energy and Industrial Technology Development Organization (NEDO; Kawasaki; www.nedo.go.jp) and Sankyo Tateyama Inc. (Takaoka, both Japan; www.st-grp.co.jp) have developed technology that enables the casting of small-diameter (500–100-mm dia.) magnesium alloy billets, which are suitable for direct, compact forging.…
Chemists from Rice University (Houston; www.rice.edu) are developing an asphalt-based powder that holds 114% of its weight in CO2. The porous material, known as asphalt-porous carbon (A-PC) captures CO2 as it leaves a natural-gas wellhead at room temperature and at…
Praxair Surface Technologies, a division of Praxair, Inc. (Danbury, Conn.; www.praxair.com), has recently introduced a new line of ceramic aluminum coatings that are said to have the same performance as legacy chromium (VI)-containing coatings. The company’s SermeTel CF and SermaLoy…
Atom transfer radical polymerization (ATRP) is a relatively new process to form carbon-carbon bonds of well-defined polymers. Since its discovery in 1995, ATRP has been performed using transition-metal complexes, such as those of copper. This feature has limited the application…
Construction has been completed on a trailer-mounted pilot plant that will produce substitute natural gas (SNG) from the products of biomass gasification (H2, CO2 and CO). Built by researchers from the Karlsruhe Institute of Technology (KIT; www.kit.edu) as part of…
A specially designed electrode could improve the efficiency of removing suspended solids, oil or other contaminants from water in applications traditionally served by dissolved-air flotation (DAF). Developers at OriginOil Inc. (Los Angeles, Calif.; www.originoil.com) believe their electrolysis process overcomes limitations…
At the European Coatings Show (April 21–23; Nuremberg, Germany), Bayer MaterialScience AG (BMS; Leverkusen, Germany; www.materialscience.bayer.com) will launch Pentamethylene diisocyanate (PDI), a new isocyanate with 70% of its carbon content originating from biomass. The eco-friendly hardner component is being evaluated…
Researchers at Toshiba Corp. (Tokyo, Japan; www.toshiba.co.jp) have developed an artificial photosynthesis system that uses solar energy to convert CO2 and water into CO with 1.5% efficiency — the highest efficiency achieved to date. The company believes the technology has…
