Lower-cost engineered composites for transportation infrastructure applications
Engineered cementitious composites (ECCs) are concrete-like materials with exceptional ductility (up to 500 times) and flexural strengths (2–3 times) greater than conventional concrete. The flexibility and strength of ECCs could benefit transportation infrastructure (for example, the ductility of ECCs could…
Geothermal brine may be a new U.S. source of lithium
Currently the U.S. has only one domestic source of lithium, a vital element in lithium-ion batteries and other products, but this could be changed through processes being developed by two California companies. Furthest along is a project of EnergySource Minerals…
This process may produce lithium from borate process waste
Rio Tinto (London, U.K.; www.riotinto.com) will shortly start up a pilot plant to produce battery-grade lithium carbonate from 90 years’ accumulated plant waste at its U.S. Borax operation in Boron, Calif. The waste is clay from the production of borates,…
A microbe for making chemicals and biofuels from brown algae
A research team from Pohang University of Science and Technology (Pohang, South Korea; www.postech.ac.kr), led by professor Gyoo Yeol Jung, and Seoul National University (Seoul, South Korea; www.useoul.edu), led by professor Sang Woo Seo, has developed a new microorganism —…
Solvent chemistry is key for cleaner oil-sands processing
Petroteq Energy Inc. (Sherman Oaks, Calif.; www.petroteq.energy) has achieved continuous operation at its oil-sands processing site in Utah, which is said to be the first commercial plant in the U.S. to extract and upgrade crude oil from U.S. oil sands.…
Novel catalyst for transforming polyethylene into lubricants and waxes
Efficient upcycling of post-consumer plastics, such as polyethylene (PE), is a key sustainability objective. New research by a team at Argonne National Laboratory (Argonne, Ill.; www.anl.gov) and Ames Laboratory (Ames, Iowa; www.ameslab.gov) has resulted in a novel catalyst material that…
Electro-swing adsorption separates CO2 from mixed gases at any concentration
Effectively separating carbon dioxide from combustion exhaust or directly from air is essential for realizing net reductions in greenhouse-gas emissions, but existing technologies for CO2 capture (such as CO2-scrubbing with amines), involve parasitic energy losses, which make carbon-capture economics unfavorable.…
Machine learning helps achieve a five-fold boost in formaldehyde yield
Chemistry professor Oliver Trapp and his colleagues at the Ludwig Maximilians-Universität München (LUM; Germany; www.en.uni-muenchen.de) have developed a new workflow for the production of formaldehyde, which is based on an algorithm constructed with the aid of machine learning (ML), optimization…
Modifying waste biomass to catalytically degrade pollutants
Sewage and wastewater often contain pollutants and environmental hormones (endocrine disruptors) that can have a negative effect on the environment and on human health. Catalysts currently used to destroy such pollutants involve high costs. And up to now, research has…
Chementator Briefs
Natural wax coating Researchers from Aalto University (Finland; www.aalto.fi) have developed a new way of making garments water-resistant, without using toxic chemicals. The treatment is non-toxic, and does not impair breathability. The coating uses carnauba wax from Brazilian palm-tree leaves.…
