2D polymer Chemical engineers at the Massachusetts Institute of Technology (MIT; Cambridge; www.mit.edu) have synthesized two-dimensional sheets of polyaramide. The achievement, described in a February issue of Nature, is said to be the first time a polymer has been grown…
Last month, Cemex, S.A.B. de C.V. (Cemex; Monterrey, Mexico; www.cemex.com) and Synhelion SA (Lugano, Switzerland; www.synhelion.com) successfully connected the clinker production process with the Synhelion solar receiver to produce solar clinker. The milestone is a first step towards fully solar-driven…
Converting propane to propylene by oxidative dehydrogenation with CO2 is an alternative route to conventional propane dehydrogenation, but existing catalysts for this conversion are not very efficient. Now, in a study described in a recent issue of Nature Catalysis, researchers…
The presence of per- and polyfluoroalkyl substances (PFAS) in wastewater and groundwater has garnered increased attention as a health and environmental issue because of their recalcitrance and bioaccumulation. To complement existing PFAS separation technologies, the Battelle Memorial Institute (Columbus, Ohio;…
A new ultra-rapid plasma-based process could significantly expand the availability of premium materials for battery applications. Developed by 6K, Inc. (North Andover, Mass.; www.6kinc.com), UniMelt is a single-pass, continuous process that employs a proprietary microwave torch technology to create a…
The transformation of sulfur-containing molecules is an important reaction in organic and pharmaceutical chemistry. However, the sulfur atom strongly coordinates with the active sites of metal catalysts, significantly decreasing the catalytic performance. Sulfur impurities contained in chemical feedstocks also cause…
A new class of electrolyte aims to bridge the performance gaps between the electrolytes used in conventional lithium-ion batteries and solid-state batteries. The new rubber electrolytes, developed by a team of researchers from Georgia Institute of Technology (Georgia Tech; Atlanta;…
Lysine (Figure 1) is an α-amino acid used in the biosynthesis of proteins. The compound contains an amino group and a carboxylic acid group. Under biological conditions, the amino group is protonated (–NH3+) and the carboxylic acid group is deprotonated…
When a pump operates inefficiently, or fails all together, the challenge is to make the most economical decision on how to remedy the situation. Some guidance is provided here Centrifugal pumps are widely used throughout the chemical process industries (CPI).…
The end of 2021 saw an important milestone for Chemieanlagenbau Chemnitz (CAC; Germany) — the successful commissioning of the first ferric chloride plant using proprietary technology. In this plant, the client from Kuwait produces a saleable product, which can be…
