A more stable way to upcycle waste plastics

A new advanced recycling process simplifies the task of breaking down polymer chains and stabilizing the resulting fragments. The Hydrochemolytic technology (HCT), developed by Aduro Clean Technologies, Inc. (Sarnia, Ont., Canada; www.adurocleantech.com), involves processing waste plastic with water, an inexpensive…

A colorful new way to visualize gaseous properties

Japan’s National Institute for Materials Science (NIMS; Ibaraki, Japan; www.nims.go.jp), along with Harvard University (Cambridge, Mass.; www.harvard.edu) and the University of Connecticut (Storrs, Conn.; www.uconn.edu), have designed a new imaging device that uses structural colors — visible colors that change…

Harvesting hydrogen from humid air

Chemical engineers from the Swiss Federal Institute of Technology Lausanne (EPFL; www.epfl.ch), in collaboration with scientists from Toyota Motor Europe (Zaventem, Belgium; www.toyota-europe.com), have invented a photoelectrochemical (PEC) “artificial leaf” that splits water vapor into H2. The technology features a…

Hydrothermal synthesis of cobalt-free lithium-ion-battery cathodes

Researchers at the U.S. Department of Energy’s (DOE; Washington, D.C.; www.energy.gov) Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have developed a hydrothermal-synthesis method for high-voltage lithium-ion battery cathodes that avoids several key issues with traditional battery processing. Key…

Quantum-based tool searches quadrillions of materials to optimize catalysts

For the first time, a quantum-computing-inspired tool has been used for catalyst discovery — specifically for the investigation of a new catalyst for the production of hydrogen via electrolysis. Created jointly by scientists from Fujitsu Ltd. (Tokyo; www.fujitsu.com) and the…

Chementator briefs

Magnet Metals Bilfinger SE (Mannheim, Germany; www.bilfinger.com) is supporting REEtec AS (Oslo, Norway; www.reetec.no) with engineering, procurement, construction and management (EPCM) services for a new processing plant for neodymium and praseodymium — two rare earth elements (REE) used in the…

Scaleup for an ethanol-to-ethylene process

Last May, Axens (Rueil-Malmaison, France; www.axens.net) started up the first ethanol-to-ethylene pilot plant based on Axen’s Atol technology with Sumitomo Chemical Co., Ltd. (Tokyo, Japan; www.sumitomo-chem.co.jp). The pilot plant, located at Sumitomo Chemical’s Chiba Works, will produce ethylene from ethanol.…

Carbon sequestration in synthetic constuction aggregate

Blue Planet Systems (Los Gatos, Calif.; www.blueplanetsystems.com) and Sulzer Chemtech Ltd. (Winterthur, Switzerland; www.sulzer.com) have announced a partnership to accelerate development of Blue Planet’s process for mineralizing carbon dioxide gas into construction aggregate for concrete. By sequestering CO2 into the…

Facts At Your Fingertips: Stainless Steels and Corrosion

Stainless steels are common materials for process equipment and components in the chemical process industries in large part because of their corrosion resistance. This one-page reference reviews the properties of stainless steels with regard to corrosion resistance. Passive layer Stainless…

A step closer to bio-based secondary diols in polyester synthesis

Isosorbide is a glucose-derived, rigid, secondary diol monomer that can impart favorable mechanical, barrier and thermal properties to condensation polymers, such as polyesters. However, for the past two decades, it has not been possible to synthesize fully bio-based poly (isosorbide…
