Novel chlorine-resistant membranes set new standards for reverse osmosis

A unique class of chlorine-resistant membranes is set to enhance the performance of processes requiring zero liquid discharge. NALA Membranes (Morrisville, N.C.; www.nalmembranes.com) has developed highly stable and durable membranes based on sulfonated polysulfone materials that overcome many of the…

‘Preorganization’ strategies allow polymer degradation through self-deconstruction

Designing plastics that can be broken down easily after their use phase have often required a trade-off between stability and ease of deconstruction. Recent research by scientists at Rutgers University (New Brunswick, N.J.; www.rutgers.edu) opens a path to resolve that…

Enzymatic splitting process cuts cost and energy consumption for fatty-acid manufacturing

Fatty acids are indispensable ingredients in a broad range of high-value products, including pharmaceuticals, cosmetics, food additives, industrial lubricants and many more. Current commercial production plants usually employ a thermal fat-splitting process that is often not economical for small- and…

New evaporative crystallizer design accelerates direct-air carbon capture

A novel crystallizer has shown promise in lowering costs for direct-air capture (DAC) of CO2 emissions. In recent work published in Nature Chemical Engineering, a research team from the University of Toronto; www.utoronto.ca), led by mechanical and industrial engineering professor…

Field-trials upcoming for salt-based thermal-energy storage demonstration program

Field trials are expected to begin shortly for a high-temperature thermal-storage demonstrator built by AED Energy (London, U.K.; www.aedenergy.com). The field trials follow the successful completion of a test program of the demonstrator at AED’s London facility. The test program,…

Electrochemical route to extracting lithium ions from ‘black mass’ could lead to more efficient battery recycling

Black mass is the powdered material resulting from shredding end-of-life lithium-ion vehicle batteries. For effective recycling, lithium must be efficiently separated from this material, but conventional methods, such as smelting at high temperatures or dissolving in strong acids, require large…

Project reveals insights about catalysts for microwave-assisted methane dehydroaromatization

Several situations, including when takeaway capacity is limited at remote oil-well sites, result in methane flaring. To avoid wasting that resource, several strategies have been explored to convert methane onsite into commercially useful liquid chemicals. One of the approaches is…

A superconducting magnet for hydrogen liquefaction is demonstrated in Germany

A first-of-its-kind demonstration unit is showcasing hydrogen liquefaction using magnetocaloric cooling, a process that demands much lower energy consumption than conventional methods used in industry. A joint venture between Magnotherm Solutions GmbH (Darmstadt, Germany; www.magnotherm.com) and Helmholtz-Zentrum Dresden-Rossendorf (HZDR; Dresden,…

Dual-action nanocomposite combines adsorption and photocatalysis for wastewater treatment

Pharmaceutical residues, particularly from antibiotics, are extremely difficult to fully remove from wastewater using traditional bulk-treatment methods, wherein antibiotic compounds are often only partially broken down. Even at trace amounts, antibiotic fragments can accumulate and wreak havoc on natural ecosystems.…

Electrostatic PFAS capture produces nearly zero waste

Increased concern around per- and polyfluoroalkyl substances (PFAS) in water is necessitating more robust mitigation techniques. There are many technologies that can effectively capture or destroy PFAS, but challenges remain surrounding large volumes of PFAS-laden solid waste and fluorinated byproducts.…
