Thermal insulation mimics polar-bear hair
Scientists from the University of Science and Technology of China (Hefei; https://en.ustc.edu.cn), led by professor Shu-Hong Yu, have developed a thermal insulator that mimics the structure of individual polar-bear hairs, and have scaled toward a material made of many hairs.…
A solvent-extraction approach for desalination of high-salinity brines
Hypersaline industrial wastewater brines are difficult to treat. Current approaches for removing salt from such brines — such as evaporative distillation and reverse-osmosis (RO) — are problematic because evaporation is highly energy-intensive and RO cannot handle salt levels present in…
A powerful tool to analyze MOFs
An international team, including staff from the Korea Advanced Institute of Science and Technology (Kaist; Daejeon, South Korea; www.kaist.ac.kr), led by Kaist’s professor Jeung Ku Kang, has developed a technology to analyze the gas adsorption behavior of molecules of each…
Thyssenkrupp introduces artificial intelligence ‘alfred’
Thyssenkrupp Materials Services GmbH (Essen, Germany; www.thyssenkrupp-materials-services.com) continues to drive digital transformation: since early 2019, an artificial intelligence (AI) solution, supported by Microsoft’s cloud platform Azure, has been integrated into the processes of the largest materials distribution and service provider…
Removing PFAS from wastewater
A new low-cost, safe and environmentally friendly method for removing polyfluorinated alkyl substances (PFAS) from water has been developed by researchers from Flinders University (Adelaide, Australia; www.flinders.edu.au). PFAS are commonly used in non-stick and protective coatings, lubricants and aviation fire-fighting…
Iodine-oxidizing bacteria could leach gold underground
Gold is usually leached from ore using hazardous substances, such as cyanide, mercury, aqua regia and others. Although there has been some progress in developing bioleaching technology, such methods still require mining and processing the ore before micro-organisms can go…
Smart retrosynthesis simplifies reaction design
A new retrosynthesis platform enables users to work backwards from a target molecule to optimize synthesis pathways. MilliporeSigma’s (Burlington, Mass.; www.sigmaaldrich.com) Synthia software uses sophisticated algorithms backed by a database of over 72,000 coded reaction rules to provide precise pathways…
A sound way to make MOFs
Researchers from RMIT University (Melbourne, Australia; www.rmit.edu.au) have demonstrated a “green” technique that can produce customized metal organic framework (MOF) compounds in minutes, harnessing the power of high-frequency (ultrasonic) sound waves. MOFs are extremely versatile materials that can be used…
Chementator Briefs
PDH catalyst Last month, Clariant's Catalyst business (Munich, Germany; www.clariant.com) launched its latest propane dehydrogenation (PDH) catalyst, Catofin 311, which is said to deliver greater selectivity and a longer lifetime than its predecessors, resulting in increased overall profitability for propylene…
Self-healing elastomers from waste lignin
Lignin — a component making up 25–35% of woody biomass — is underutilized as a byproduct of biofuels production and paper-making processes. Because of its abundance, low-cost and sustainability, lignin is being investigated as a raw material for making higher-value…
