Falling Films in Vessel CIP Applications
Applying an understanding of flow regimes and turbulence to clean-in-place (CIP) processes can optimize CIP cleaning efficiency, reducing water, solvent, energy and chemical use, while maintaining cGMP cleaning performance For vessels and bioreactors in bioprocessing applications, designing clean-in-place (CIP) cycles…
Microwave irradiation and ion exchange lower cost of battery upcycling
Approaches for recycling cathode active materials from used lithium-ion batteries generally face a tradeoff wherein recovering materials with the widest range of possibilities for re-use, such as pyrometallurgical methods, generally require high energy and long process times, while direct-recycling approaches…
Autonomous chemistry system identifies high-performing and tunable catalysts
Researchers at North Carolina State University (NCSU; Raleigh; www.ncsu.edu) and the University of North Carolina (Chapel Hill; www.unc.edu), with the support of Eastman Chemical Co. (www.eastman.com), have developed a closed-loop autonomous catalysis platform for identifying high-performing catalyst formulations and for…
Taming reactive radicals to streamline C-glycoside drug synthesis
Many widely used pharmaceuticals depend on a carbohydrate class known as C-glycosides, which are metabolically stable and acid-resistant. Although they can be made from common sugars like dextrose, C-glycosides have proven difficult to synthesize due to the preponderance of hydroxyl…
Precise molecular order results in remarkably thin monofilaments
A materials-science breakthrough for the production of ultra-fine monofilaments is now being commercialized by startup firm Z-Polymers (Lowell, Mass.; www.z-polymers.com). The company’s Tullomer-branded monofilaments support exceptionally thin functional fibers with low creep and shrinkage, while exhibiting extremely high mechanical strength…
Low-energy carbon capture using food-production byproducts
Direct-air capture (DAC) of carbon dioxide from the atmosphere is required to meet climate goals, but highly effective and inexpensive DAC remains elusive. Researchers at ETH Zurich (www.ethz.ch) have developed a novel approach using waste proteins from dairy and tofu…
Field trials demonstrate the ability of novel scavenger to remove H2S from natural gas
Field demonstration trials of a novel method for removing hydrogen sulfide (H2S) from natural gas were recently completed in the Permian basin (Texas, USA). The trials demonstrated the ability of the technology, known as ECOTREAT®, to remove H2S from gas…
Spark ablation technology cuts iridium use by 90% in PEM water electrolysis
Proton-exchange membrane (PEM) water electrolysis holds significant promise for “green” hydrogen production, but broader adoption hinges on reducing dependence on costly platinum-group metals, such as iridium. A new production method for ultra-thin nanoporous layers developed by VSParticle B.V. (VSP; Delft,…
Air Liquide to invest $150 million in industrial gas facility in Idaho for semiconductor manufacturing
Air Liquide S.A. (Paris, France) announced today an investment of over $150 million to build, own and operate a new industrial gas production facility in Idaho to support the site expansion of a global leader in semiconductor memory chips. Building…
JordProxa named technology and equipment partner for Lilac Solutions’ Great Salt Lake lithium carbonate facility
JordProxa (St. Leonards, New South Wales, Australia) has been announced as the technology and equipment partner for Lilac Solutions (Oakland, California), a leading provider of direct lithium extraction (DLE) technology, for the lithium downstream conversion process at its Phase 1 commercial lithium carbonate…
