Scientists from Lawrence Livermore National Laboratory (LLNL; Livermore, Calif.; www.llnl.gov) have combined biology and 3-D printing to create the first reactor that can continuously produce methanol from methane at room temperature and pressure. The team removed enzymes from methanotrophs —…
Scientists from the National Chung Hsing University (Taichung, Taiwan; www.nchu.edu.tw), led by professor Ming-Yen Wey, have successfully developed an alternative route for recycling plastic solid waste. They used waste polystyrene to develop membranes suitable for processes such as carbon capture,…
Post-combustion carbon-capture processes that are based on adsorption of CO2 by amine compounds reduce the power output of coal- and natural-gas-fired power plants largely due to the energy required to regenerate the CO2 from the adsorbent material. In another approach,…
Colloidal glasses develop structural color through constructive interference. The color can be tuned by adjusting interparticle distance, making the colloidal glasses attractive for use as color pigments for use in coatings, displays, colorimetric sensors and optical barcodes. While colloidal crystals…
Computational technology from Arzeda Corp. (Seattle, Wash.; www.arzeda.com) can streamline the development of novel enzymes, as well as improve existing enzymes, for industrial fermentation. The company’s proprietary computational platform, known as Archytas, uses advanced algorithms to design and screen a…
Last April, a demonstration plant started up for the production of hydrogen from aluminum-based composite waste. The startup marks the culmination of a project, supported by NEDO, in which Alhytec Inc. (Takaoa City, Japan; www.alhytec.co.jp) developed the process to separate…
Last month at the IFAT trade fair (May 30–June 3; Munich, Germany), Huber SE (Berching: www.huber.de) and Microdyn-Nadir GmbH (Wiesbaden, both Germany: www.microdyn-nadir.de) unveiled a rotating membrane bioreactor (MBR) that utilizes membrane laminate technology. “By combining our two technologies we…
By the end of this year, a demonstration plant will start up in the U.S. that uses an electrochemical process to recover phosphorus from wastewater, producing a fertilizer as struvite (NH4MgPO4·6H2O). Although the location and capacity of the plant has…
Polylactic acid (PLA) is a versatile biopolymer, but its applications are somewhat limited due to its brittleness. Now, an alternative bio-based composite material has been developed that overcomes this limitation. Developed by the industry-university consortium of Hitachi Zosen Corp. (HITZ;…
Cooling-tower motor A new electric motor for driving cooling-tower fans features a design that prevents current from flowing through the shaft bearings, allowing longer lifetime and less maintenance. The TEAO motor, made by Marathon Motors Corp. (Wausau, Wis.; www.marathonelectric.com) also…
