Aerobic oxidation of a biomass-derived substrate [5-(hydroxymethyl)furfural; HMF] in methanol and ethylene glycol produces monomers MFDC — the methyl ester of furan-2,5-dicarboxylic acid (FDCA) — and HEFDC — the ethylene glycol ester of FDCA. These monomers are recognized as crucial…
An international study has found that coal-fired power stations emit more ultrafine dust particles than road traffic and that those dust particles can modify rainfall patterns and can, in general, have considerable impact on the climate. The study found that…
In early April, 6th Wave Innovations Corp. (Salt Lake City, Utah; www.6wic.com) and CyPlus GmbH (Hanau-Wolfgang, Germany; www.cyplus.com) signed a sales and marketing representative agreement for IXOS nanotech gold extraction resin for the mining industry. CyPlus will represent 6th Wave…
Bio-based isobutanol is attractive as a renewable blendstock for gasoline because it has higher energy density than bioethanol, and does not impose vehicle-range penalties as a fuel additive, but thus far, processes to synthesize and isolate isobutanol have required a…

As benefits become apparent, the acceptance of modular process systems grows and the concept finds new opportunities While providers of modular process systems and facilities will tell you modular builds were once a hard sell, modularization is now sought after…
Hydrogen gas is used widely in industry, including in metal annealing, float-glass production and silicon wafer manufacturing, among others, but greater than 80% of the H2 used for these processes is typically vented or flared as waste. A new electrochemical…
The transition-metal-catalyzed reduction of nitrogen is an alternative to the traditional energy-intensive Haber-Bosch process for producing ammonia. In these reaction systems, metallocenes or potassium graphite are typically used as the reducing reagent, and conjugate acids of pyridines or related compounds…
The first high-strength, wrought-aluminum alloy powder designed for use in additive manufacturing (3-D printing) applications is moving into commercial production. The powder was developed by HRL Laboratories (Malibu, Calif.; www.hrl.com) for use in laser powder-bed fusion 3-D printers. The company…
Scientists at the Chinese Academy of Sciences (Beijing; www.cas.cn) and Yangzhou University (Jiangsu, China; www.yzu.edu.cn) have developed a technique for disinfecting water by using graphitic carbon nitride sheets. They claim their technique purifies water in 30 minutes, killing more than…
