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,…
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…
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.…
Powerful palladium “plugs” make this hydrogen-separating membrane more durable
Palladium is widely used in membrane applications because of its extreme selectivity for hydrogen. However, conventional palladium membranes can be damaged at the high temperatures required for many processes that generate hydrogen for various subsequent uses, including the manufacture of…
Niobium-based anodes create high-speed lithium ‘highways’
By replacing traditional silicon or graphite anode materials with specially crystallized niobium, manufacturers can overcome some of the safety and power limitations of traditional lithium-ion batteries (LIBs). Echion Technologies Ltd. (Cambridge, U.K.; www.echiontech.com) has developed a proprietary mixed niobium-oxide active…
Method for breakdown and removal of siloxanes from fluids garners patent
Siloxanes — synthetic chains of alternating silicon and oxygen atoms — are widely used in personal care products, soaps, pharmaceutical formulations and other products, but are notoriously difficult to manage in production- and waste-fluid streams. Current approaches, including flaring and…
