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…
Chementator Briefs
Li2CO3 from brine Purities of greater than 99.9% for battery-quality lithium carbonate have been achieved using a proprietary artificial-intelligence-powered crystallization technology developed by Standard Lithium Ltd. (Vancouver, B.C.; www.standardlithium.com). The total cation contaminant levels were reduced from nearly 2,500 parts…
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…
Converting solid waste to ketones
Researchers at Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) recently reported a process for converting various blends of cellulosic biomass and municipal solid waste (MSW) into aliphatic methyl ketones. The team used bio-derived ionic liquids to first break down the…
Simultaneously treat many mixed-waste streams
A team of researchers at Worcester Polytechnic Institute (WPI; Worcester, Mass.; www.wpi.edu) are investigating hydrothermal liquefaction (HTL) to simultaneously treat a variety of municipal waste streams and create biofuels. “HTL is an emerging technology for the conversion of various types…
Validating hydrogen embrittlement models for steel tanks
Hydrogen is transported in steel tanks and pipelines. However, H2 causes embrittlement of steels by accumulating at microstructures called dislocations and at the boundaries between the individual crystals of which the steel is composed. The accumulation of hydrogen weakens the…
