Fuel-cell-based carbon capture system can augment power generation
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,…
A glass for all colors
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 approach streamlines industrial enzyme development
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…
Making H2 from aluminum composite waste
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…
A next-generation membrane bioreactor
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…
Engineering surfaces to repel all liquids
Nature-inspired surfaces are being developed that are not only highly repellent to water, but are even superomniphobic Although hydrophobic materials have been in use for many years, advances in nanotechnology are causing a revolution in the coatings and surface-treatment field.…
Defining Sustainability in the Chemical Process Industries
This article examines the measures — both global and local — that chemical processors are taking to instill sustainability into everyday operations Although discussions about sustainability in the chemical process industries (CPI) are usually geared toward making processes more environmentally…
Gearing Up for Protection Against Chemicals
The CPI requires more innovative and comfortable chemical-resistant clothing, goggles and gloves to protect workers The purpose of chemical protective clothing (CPC) is to shield and protect workers from chemicals. However, explains Sally J. Smart, a Certified Safety Professional and…
Chementator Briefs
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…
Sun and rain generate electricity in this solar cell
An all-weather solar cell that generates electricity by both sunlight and rain has been developed by researchers led by professor Qunwei Tang from the Institute of Material Science and Engineering at Ocean University of China (Qingdao; http://eweb.ouc.edu.cn) and professor Peizhi…
