Chemists from the Institute of Inorganic and Analytical Chemistry at the University of Freiburg (Germany; uni-freiburg.de) have synthesized a cationic, low-valence aluminum complex salt. “So far, there has been only one example of a cationic, low-valent aluminum compound, but it…
Last month at Achema 2022 (August 22–26; Frankfurt am Main, Germany), Q.ANT GmbH (Stuttgart, Germany; www.qant.de) introduced what is said to be the world’s first industrial-grade quantum sensor (photo) for particle analysis. By the use of super-fast software, electronics and…
Conventional gas-separation membranes normally exhibit a trade-off between selectivity and permeability — a practical limitation referred to as the Robeson upper bound. As a result, membranes designed to selectively remove relatively low concentrations of carbon dioxide from natural gas or…
A new class of adhesives being developed by the startup gluECO Adhesives LLC (Ashburnham, Mass.; www.glueco-adhesives.com) is based on corn proteins and has a host of environmentally friendly properties, such as biodegradability and the ability to be easily removed in…
Biomethane Last month, NextChem, a subsidiary of Maire Tecnimont S.p.A. (Rome, Italy; www.mairetecnimont.com) was awarded a contract by ENGIE subsidiary Storengy (Bois-Colombes Cedex, France; www.storengy.com) to perform an advanced basic-engineering study for a plant that will produce second-generation biomethane from…
Circular dichroism (CD) is the established method for distinguishing between enantiomers — the optical isomers of molecules that are mirror images of each other. In this approach, circularly polarized light is passed through the sample and is absorbed differently by…
Last month, operation began at Polar Night Energy Oy’s (Tampere, Finland; www.polarnightenergy.com) first commercial sand-based thermal-energy storage system. The thermal storage system, which is located at the Vatajankoski power plant, is now producing low-emission district heating to the city of…
In an advancement toward circularity for commodity plastics, researchers at the Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have developed a method for upcycling the commodity thermoplastic acrylonitrile butadiene styrene (ABS) into an ABS-vitrimer material that can be…
Currently, enhanced biological phosphorus removal (EBPR) techniques in municipal wastewater-treatment plants (WWTPs) do not work well at temperatures above 25°C, which is common in warm countries. This limitation is expected to extend to more countries with the advent of global…
An interdisciplinary team of biologists, chemists and engineers from the University of Portsmouth (U.K.; www.port.ac.uk) have become the first to successfully grow a limpet-inspired biomaterial with extreme strength. The common limpet (Patella vulgata) is a small, snail-like mollusk with a…
