We all play a part in cyber-vigilance

As connected devices and systems have become more advanced, engineers in turn have become savvier about the realities of a digitally connected enterprise, especially with regard to securing their operational technology (OT) systems. Even with globally increasing cybersecurity awareness, however,…

Enhancing Characterization of Thermal Barrier Coatings

Combining microscopy and machine-learning techniques leads to faster, more precise analyses of critical coating materials When the SR-71 Blackbird aircraft was designed to soar at three times the speed of sound, engineers faced an extreme challenge: managing the heat generated…

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…

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,…

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…

Mosaic to sell its potash assets in Carlsbad, New Mexico

The Mosaic Co. (Tampa, Fla.) announced that it has signed a definitive agreement to sell Mosaic Potash Carlsbad, Inc., including the operations, assets and liabilities of the Mosaic mine in Carlsbad, New Mexico to International Minerals Carlsbad, LLC for $30…
