Viscosity is an important property for understanding the flow behavior of liquids, mixtures, emulsions, slurries and other materials in industrial processes. This one-page reference provides a refresher on conceptualizing viscosity. Intermolecular forces Viscosity is a measure of a material’s resistance…
Understanding the different types of activated carbon products, their specific properties and best practices for use is essential to the design of effective environmental treatment processes Activated carbon is a type of manufactured carbon material used for a range of…
Researchers at the University of Bayreuth (Germany; www.uni-bayreuth.de) have developed nonwoven materials that exhibit an unusual combination of high electrical conductivity and extremely low thermal conductivity. These composites of carbon and silicon-based ceramic can be manufactured and processed cost-effectively by…
A research team, led by scientists at the Center for Molecular Bioengineering (B CUBE) at the Technical University of Dresden (Germany; www.tu-dresden.de), has converted mineral shells of single-celled algae into lead-halide perovskites with tunable physical properties. The new perovskites have…
In synthesizing a new molecule that mimics the nickel-iron (NiFe) hydrogenase enzyme, a team of researchers from University of Illinois Urbana-Champaign (www.illinois.edu) may have uncovered a promising alternative to the platinum-based catalysts typically used in the electrolysis of water to…
Good Things Come in Smaller Packages Standard Xchange, a Xylem brand, is pleased to announce the addition of two new compact, low-cost, high-energy efficiency models to its Plateflow® line of gasketed plate and frame heat exchangers. Through advanced engineering and high-efficiency technology, Standard Xchange High Energy Efficiency Plateflow®…
Chemists at Hokkaido University (Sapporo, Hokkaido, Japan; www.global.hokudai.ac.jp) and the Institute for Chemical Reaction Design and Discovery have developed what is said to be the first high-performance catalyst specifically designed and optimized for solid-state, mechanochemical synthesis. The new approach was…
Last month, the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) awarded $3.2 million in funding for the Solar MEAD project, which aims to decarbonize cement production. This joint project is headed by Cemex, S.A.B. de C.V. (Cemex; Monterrey, Mexico;…
For the first time, a hydrocarbon-based membrane has passed the performance and durability testing standards set by the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) for heavy-duty fuel-cell applications. Typically, membranes in fuel cells are made of perfluorinated materials…
Chemical recycling of waste polyolefins is difficult to achieve economically partly because of the stability of carbon-carbon bonds in the plastics. In a new approach, researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) and the Technical University of…
