A new method to study nanoparticles
Researchers from the Singapore-MIT Alliance for Research and Technology (Singapore; https://smart.mit.edu) have discovered a way to study the properties of a nanoparticle without damaging it, which has not been possible so far. The work was led by Michael Strano, a…
Waste garlic stems make an adsorbent for arsenic removal
Professor Monoj Kumar Mondal and Anuj Kumar Prajapati from the Dept. of Chemical Engineering and Technology, Indian Institute of Technology (Banaras Hindu University, Varanasi, India; www.iitbhu.ac.in) have used nanoporous activated garlic stem carbon (AGSC) — prepared from garlic stem waste…
Integrated AC process eliminates refrigerants
With the goal of decreasing the climate impact of residential air conditioning (AC), Kraton Corp. (Houston; www.kraton.com) has developed the NexarCool technology in collaboration with Texas A&M University (College Station; www.tamu.edu), India Institute of Technology Bombay (www.iitb.ac.in) and Indian companies…
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…
Chementator Briefs
Direct route to PG Dow Inc. (Midland, Mich.; www.dow.com) and Evonik Industries AG (Essen, Germany; www.evonik.com) have entered into an exclusive technology partnership to develop a new process to make propylene glycol (PG). The key to the so-called Hyprosyn process…
Pursuing methanation as a means to recycle CO2
By the end of fiscal 2019, commissioning and continuous operation will begin on a new methanation plant that will produce 8 Nm3/h of methane from CO2 and H2. The test facility, located at the Koshijihara Plant of Inpex’s Nagaoka Field…
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…
