Researchers developed a solar-spectrum-driven photocatalytic leaching method that uses mild organic acids and a reusable catalyst to extract critical metals from spent lithium-ion battery cathodes under simulated sunlight. The system achieved high leaching efficiencies across several cathode chemistries, while process modeling projected lower environmental impacts and competitive economics compared with conventional recycling routes.
Crystal Pharmatech, a science-driven CRO/CDMO specializing in solid-state research, preformulation studies, and formulation development and manufacturing for small-molecule drugs, today announced that installation of the ELDICO ED-1 electron diffractometer at its Suzhou, China R&D center is complete.
Researchers developed a generally room-temperature, additive-free nickel method that activates strong C-F bonds in polyfluoroarenes to form air- and moisture-stable nickel(II) diaryl complexes from commercially available starting materials. The complexes show high regioselectivity, tolerate several reactive functional groups, and respond differently to heat and light depending on their aryl and bipyridine substituents.
Mouser Electronics, Inc., the New Product Introduction (NPI) leader™ empowering innovation, today announces the newest issue of the Methods technology and solutions journal, available with a free subscription.
Researchers developed machine-knitted magnetoactive textiles that combine wireless charging, biomechanical sensing, and tactile feedback in a single textile transducer using a soft magnetic fiber and knitted electromagnetic coils. The system charged a 7.4 V battery, detected motion signals up to 3,000 Hz, produced haptic forces up to 4.2 mN, and was demonstrated in choker, glove, and sleeve prototypes.
Understanding how ions move through solid materials is key to advancing technologies such as batteries, fuel cells and sensors.
Researchers used transient grating spectroscopy to track elastic changes associated with spinodal decomposition in Fe-Cr alloys, linking TGS measurements in Fe-36Cr with atom probe tomography and composition-based modeling. The work shows that the elastic response depends on chromium content and points to TGS as a potential non-destructive method for monitoring thermal aging in high-chromium ferritic phases.
Mechanical microembossing altered the surface structure and near-surface PLA/PBAT distribution of 70/30 blend films while preserving previously reported water-repellent behavior. Under controlled incubation with Bacillus subtilis, patterned films showed greater biodegradation-related mass loss than untreated films, with the largest loss reaching 7.50% after 115 days.
A collaboration between the University of Illinois Urbana-Champaign's Grainger College of Engineering and the University of Notre Dame has broken the world record for optical switching speed in quantum well LEDs.
Researchers engineered asymmetric copper sites in Cu/ZIF-8 to drive Fenton-like hydroxyl radical generation at neutral pH, addressing a key chemical limitation in polishing 4H-silicon carbide. In CMP tests, the catalyst raised the material removal rate to 62.4 nm min?¹ while producing subnanometre surface roughness and low residual dissolved copper.
