New process efficiently filters hormones from water
Drinking water can be contaminated with micropollutants, including steroid hormones that are used as medical substances and contraceptives. Although their concentration in wastewater may be only a few nanograms per liter, this small amount can already damage human health and…
Increasing energy density in capacitors
Capacitors are attractive in large-scale energy-storage applications, such as electric vehicles or grid storage, because of their ability to rapidly charge and discharge, but their energy densities have been too small to allow their use in such applications. Researchers at…
Chementator Briefs
Ethylene dichloride Recently, Chemetry (Moss Landing, Calif.; www.chemetrycorp.com) and Braskem (Sao Paulo, Brazil; www.braskem.com) announced their intent to construct and operate a demonstration plant using Chemetry’s eShuttle technology for the production of ethylene dichloride (EDC) in Brazil. The initial focus…
Biogas from brewery wastewater makes power with a fuel cell
This month, a demonstration project to generate power from fuel cells running on biogas has begun at Asahi Breweries’ Ibaraki Brewery. Coordinated by Asahi Quality & Innovations, Ltd., an independent research subsidiary of Asahi Group Holdings, Ltd. (Tokyo, Japan; www.asahigroup-holdings.com),…
Fruit peels help recover metals from e-waste
Scientists from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg), led by professor Madhavi Srinivasan, have developed a method of using orange peel waste to extract precious metals from spent lithium-ion batteries and to make batteries from those recovered metals, creating minimal…
Chementator Briefs – Sept. 2020
Smart Stir Bar Scientists at the University of Warwick (Coventry, U.K.; www.warwick.ac.uk) have developed a magnetic stir bar with an integrated process monitoring system. Described in a recent issue of ACS Sensors, the Smart Stirrer has an integrated microprocessor and…
New Japanese project targets CO2 and brine utilization
A new project has been selected by the New Energy and Industrial Technology Development Org. (NEDO; Tokyo, Japan; www.nedo.go.jp) that aims to recover useful salts from desalination brine or seawater, as well as mineralizing CO2 into a useful product. The…
Coretec partners with Evonik to produce cyclohexasilane
The Coretec Group Inc. (Ann Arbor, Mich.; www.thecoretecgroup.com) recently entered a supply partnership with specialty chemical company Evonik Industries AG (Essen, Germany; www.evonik.com) in which Evonik will produce cyclohexasilane (CHS; Si6 H12) for application development using intellectual property developed by…
Upcycled silicon improves LIB energy storage
Silicon is seen as a promising alternative to graphite in lithium-ion battery (LIB) anodes, due to its abundance and higher energy-storage capability — silicon is said to store ten times more energy than graphite in LIB applications. However, manufacturing processes…
New fabrication method for fluorine-containing carbon-capture membranes
Recent work by a team of researchers from Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) and the University of Tennessee (Knoxville; www.utk.edu) has brought cost-effective, fluorinated carbon molecular-sieve membranes within closer reach. To make the membrane, the researchers…
