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…
