Bacteria for wastewater treatment

Researchers from the National University of Singapore (www.nus.edu.sg), led by associate professor He Jianzhong, have found a new strain of bacterium called Thauera sp. strain SND5, which is capable of simultaneous nitrification and denitrification and phosphate removal from wastewater. The…

Magnetic field cures adhesives faster with less energy

Conventional adhesives, such as epoxy, are designed to cure using moisture, heat and light. Curing is necessary to cross-link and bond the glue with the two secured surfaces as the glue crystallizes and hardens. Now, scientists from Nanyang Technological University…

Membrane-based system for low-cost CO2 capture to be demonstrated at engineering scale

A new membrane technology for separating carbon dioxide from exhaust gas will be scaled up for real-world testing under a project to evaluate low-cost CO2 capture at a coal-fired power plant. Design and testing of an engineering-scale CO2-capture system will…

Storing excess electricity as high-temperature heat

Late last November, the energy-transition start-up company Lumenion GmbH (Berlin, Germany; www.lumenion.com) received the 2020 Berlin Brandenburg Innovation Prize for its high-temperature, steel-based energy-storage technology. The system stores peaks of wind and solar energy by heating a steel core to…

A breakthrough in artificial intelligence-enabled materials discovery

A groundbreaking artificial intelligence (AI) algorithm, dubbed CAMEO (Closed-Loop Autonomous System for Materials Exploration), rapidly identified a potentially useful new material — a germanium-antimony-tellurium alloy (Ge4Sb6Te7) that is optimized for phase-change applications in data storage and photonic-switching devices. Tasked with…

Membrane extraction improves biofuel yield

Typically, the production of fuel-grade chemicals, such as butanol, from biomass fermentation processes involves low-yield batch processes and high energy costs. Now, researchers from Imperial College London (ICL; www.imperial.ac.uk), in partnership with bp plc (London; www.bp.com), have demonstrated a new…

January Chementator Briefs

MDI Production Late last year, Covestro AG (Leverkusen, Germany; www.covestro.com) started up a pilot plant for the production of methylene diphenyl diisocyanate (MDI) based on the innovative AdiP (adiabatic-isothermal phosgenation) technology at its Brunsbüttel site. The new technology promises to…

Enhancing photocatalytic activity by tuning wall thickness of TiO2 nanotubes

Titanium dioxide is well known as a photocatalyst, and is especially promising for degrading organic-based contaminant molecules in wastewater. Researchers from China and Australia have reported, in a recent issue of the Journal of Colloid and Interface Science, that controlling…

Immobilizing enzymes for biosensors

A new technique for making less-expensive, more-efficient biological enzyme hybrids could have widespread applications, including in water recycling, drug manufacturing and molecular biology. The technique, developed by a team from Australia and the U.S., involves using a vortex fluidic device…

Radiative cooling: A coating for windows that also cools

A Korean team has proposed an approach for passive radiative cooling. The team, which includes professors Junsuk Rho and Jin Kon Kim of Pohang Universiy of Science and Technology (Pohang, South Korea; www.postech.ac.kr) and professor Heon Lee of Korea University…
