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.
Polarons are fundamental quasiparticles in solids. (Quasiparticles are excitations that act like particles despite their complex many-body interactions with their environment.)
Some of the most important discoveries in materials science and structural biology come down to a simple question: where, exactly, are the atoms- The arrangement of atoms determines nearly everything about how a material behaves in the real world — how strong it is, how it conducts electricity, how a battery stores energy, or how a drug binds to a cell.
Researchers directly imaged voltage-driven blistering in two-dimensional nanochannels and linked those structural changes to ionic conductance, hysteresis, and memory. Their experiments and modeling show that osmotic and electrostatic forces can drive different blister responses, helping explain why nominally similar nanofluidic devices behave differently.
