Oxidative precipitation recovers nickel and cobalt from ore
An alternative method for processing mixed nickel-cobalt hydroxide precipitate to separate the nickel from cobalt and manganese has been proposed by a team from the Bandung Institute of Technology (Bandung, Indonesia; www.itb.ac.id), the Indonesian Institute of Sciences (Bandung) and the…
A desalination process that pumps ions instead of water
Researchers from Indonesia’s Bogor Agricultural University (Bogor, Indonesia; www.ipb.ac.id), the University of Bath (U.K.; www.bath.ac.uk), and the University of Johannesburg (Johannesburg, South Africa; www.uj.ac.za), led by Budi Riza Putra, have developed a low-cost, low-energy and low-maintenance, solar-powered desalination system that…
This gold catalyst improves CO2 reduction
Researchers from the Korea Advanced Institute of Science and Technology (KAIST; Daejeon; www.kaist.ac.kr) have developed a three-dimensional (3D) hierarchically porous nanostructured catalyst that is said to have a CO2-to-CO conversion rate up to 3.96 times higher than that of conventional…
Semiconducting material combines handedness and polarity
A semiconducting material synthesized by researchers at Rensselaer Polytechnic Institute (RPI; Troy, N.Y.; www.rpi.edu) could enable new ways of manipulating electronic materials remotely using light. The material, explains RPI professor of materials science and engineering Jian Shi, derives its unique…
Wood-supported catalyst safely keeps fruit fresh
Ethylene is a multifunctional phytohormone that regulates growth, ripening and other functions in plants. For example, bananas stored next to apples will ripen quickly due to the ethylene released from the apples, which in turn are triggered to release more…
Self-healing, recyclable solid electrolytes for Li-ion batteries
Energy-storage researchers have been in search of safer electrolytes for lithium-ion batteries, because of persistent concerns over possible overheating and fires resulting from dendrite formation in the anode. Solid polymer electrolytes have been explored to address these issues, but achieving…
Commercializing vacuum-microwave drying for pharmaceuticals
Vacuum-microwave drying for pharmaceuticals is much faster than other techniques, such as freeze drying or air drying, but the difficulty in achieving homogenous microwave-energy distribution under vacuum conditions has made it difficult to scale up for commercial manufacturing. “What tends…
Metabolic engineering allows robust, standardized fermentation that is predictive at scale
Production of bio-based chemicals has important environmental, cost and functional benefits, but historical approaches have lacked robustness to the commercial process environment and have proven costly to develop. A platform technology developed by DMC Biotechnologies (Boulder, Colo.; www.dmcbio.com) was designed…
Chementator Briefs
Caprolactam Genomatica (San Diego, Calif.; www.genomatica.com) recently announced the production of the world’s first renewably sourced ton of caprolactam, the key ingredient for nylon-6. The company made the caprolactam by fermenting plant sugars with engineered microbes, departing from the conventional…
Bio-inspired textiles recover oil from water
A technology that removes oil from the surface of water without pumps or chemicals has been developed by German researchers at the Universities of Bonn (www.uni-bonn.de) and Aachen (www.uni-aachen.de) and textile-manufacturer Heimbach GmbH (Düren, Germany; www.heimbach.com). Textiles with special surface…
