Chemical engineering is a branch of engineering that deals with the processes (production, transformation, transportation and usage) necessary to produce useful materials and energy. Chemical engineers apply knowledge from the physical and biological sciences as well as mathematics and economics.
Achieving a circular system for electronics hinges on greener design and effective recycling methods. Now, research presents a more durable printed circuit board that can also be sustainably and effectively recycled.
A membrane inspired by the arsenic–protein interactions in biological systems allows the efficient removal of various arsenic species from contaminated water.
Cutting-edge chemistry is often performed in non-atmospheric conditions. Continued development of the Chemputer platform now enables the utilization of sensitive compounds in automated synthetic protocols.
Achieving a net-zero future requires that hard-to-abate sectors be addressed. Co-production offers an opportunity to mitigate chemical and steel sector emissions by extracting H2 and CO from steelmaking off-gas and using them for chemical syntheses. The authors examine carbon mitigation and costs of co-producing chemicals and steel in China.
Hydroxylamine plays a critical role in the chemical industry, but its production currently has unfavourable environmental footprint. Now a plasma-electrochemical cascade pathway powered by electricity enables efficient hydroxylamine synthesis from ambient air and water at mild conditions.

The carbon footprints of petrochemicals have large uncertainties, challenging decarbonization efforts. Now, a study identifies the main uncertainty sources and strategies for improving the accuracy of greenhouse gas emissions estimations and reporting for petrochemicals.
Liquid–liquid extraction is an indirect separation technique requiring solvent regeneration, and if a back-extraction is needed, it typically reduces the concentration. Now, using an electrochemical reaction, the concentration can be pumped up to 16 times the feed concentration.
