Nucleic acid-based medications, such as mRNA vaccines, are opening up new therapeutic approaches. These active ingredients must be enclosed inside nanoparticles to ensure that they get to where they are needed inside the body’s cells. The Fraunhofer Institute for Production…
At the 2024 Spring Meeting of the American Institute of Chemical Engineers (AIChE; www.aiche.org), a team from the National Energy Technology Laboratory (NETL; www.netl.doe.gov) presented on a recently patented technology for the removal of critical and heavy metals from wastewater…
Brewers’ spent grain (BSG) is the most significant byproduct of the beer-brewing industry, making up 85% of the total waste. Globally, about 36.4 million ton/yr of spent grain are produced. This spent grain is typically discarded after its primary use…
Gallium and germanium are considered critical materials due to their multiple uses in semiconductors, optics, healthcare and pharmaceuticals, and other high-technology applications. Current solvent-based extraction methods for recovering these elements suffer from significant drawbacks, such as low separation efficiency, poor…
Bipolar plates (BPPs) are a key component in electrolyzers and fuel cells. BPPs include two key components: the membrane electrode assembly (MEA), in a fuel-cell system; and the catalyst-coated membrane (CCM), in an electrolyzer. In a fuel-cell stack, for example,…
Membranes are widely used in a variety of industrial separation processes, but the polymeric materials that make up many membranes are not durable enough to handle extreme conditions, such as processes with low pH or hazardous-metal content. Membrion, Inc. (Seattle,…
NanoTech Materials Inc. (Houston; www.nanotechmaterials.com) is expanding its commercial partnerships for the use the company’s Insulative Ceramic Particle (ICP) technology, which can be used in fireproof coatings, as well as in a range of applications for roof coatings that lower…
RO Membranes Toray Industries, Inc. (Tokyo, Japan; www.toray.com) has developed a highly durable reverse osmosis (RO) membrane that is said to offer double the resistance to cleaning chemicals of conventional counterparts. This reduces performance degradation from membrane wear and simplifies…
Hydrogen fuel cells and electrolyzers will be crucial technologies as the global energy transition progresses. However, both devices are often hampered by issues with durability and material costs — mainly associated with their membrane elements — which have slowed their…
Hydrogen chloride is an important byproduct of the chemical industry, with over 9-million ton/yr generated by industrial chlorination processes, such as the production of chloromethanes and polymers (polyurethanes and polycarbonates). Although HCl can be easily recovered by gas scrubbing with…
