Extracting zinc from flyash

In Sweden, incineration of household waste in waste-to-energy (WtE) plants is common, and generates around 250,000 metric tons (m.t.) of flyash every year. The rest of Europe accounts for around ten times that amount. Most of this waste is landfilled,…

Printing sensors onto stickers

Advanced sensors are crucial to any predictive maintenance strategy, and often these sensors must be quickly installed into difficult-to-reach spaces. A novel nanomaterial technology enables predictive sensors that can be “printed” onto flexible stickers. These stickers can be easily attached…

February Chementator Briefs

Ammonia catalyst Clariant Catalyst (Munich, Germany; www.clariant.com) and Casale SA (Lugano, Switzerland; www.casale.ch) have developed a new ammonia synthesis catalyst for sustainable CO2 reduction. Based on Clariant’s AmoMax 10 — a wüstite-based alternative to traditional magnetite-based catalysts — the AmoMax-Casale…

Metal-oxide nanocrystals have applications in lubrication and electronics displays

Pixelligent Technologies Inc. (Baltimore, Md.; www.pixelligent.com) has developed a process for making metal-oxide nanocrystaline materials that have found uses as additives in a variety of industrial lubricants, mixed- and augmented-reality (AR/MR) glasses, and various display technologies. The company’s PixClearProcess results…

Nanoscale uniformity of desalination membranes

Reverse-osmosis (RO) desalination membranes use a polyamide selective layer formed on a microporous support to separate water molecules from salts. Past efforts to characterize the polyamide membrane structure have been limited by the internal variability of the selective layer. Now,…

A microreactor for continuous formation of Grignard reagents

Today, synthetic routes to about 10% of the top 50 active pharmaceutical ingredients (APIs) include one or more Grignard reactions, which are used to form C–C bonds. Normally, the reaction is performed batch-wise in continuous stirred-tank reactors (CSTRs), with Grignard…

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…
