Researchers correlated X-ray maps of titanium oxidation state with local electrochemical probing of single Ti3C2Tx flakes; redox activity extended well beyond the point of contact.
Heat-treating copper foil at about 850 °C ordered its grain boundaries. Lithium then plated flat, and laboratory anode-free cells lasted more than five times longer.
A theoretical study from Japan's Institute for Molecular Science reproduces most of a puzzling infrared signal in a perovskite film without any change in molecular vibrations.
Argonne researchers benchmarked three single-crystal iridium faces in acid and alkali. Activity depends on the face and on pH, and alkaline media produce much more hydrogen peroxide.
Engineers poured concrete into a sewn fabric mold to make a beam with voids where solid material was not needed. The test beam stayed close to the computer model.
A team from Charles University and the University of Cambridge showed that current pulses switch UTe₂ between low and high critical current density states, and the state persists for hours.
Microscopy and simulations show the blue peak of the non-spectral magenta in Anna's hummingbird feathers arises from interaction of the top and middle melanosome layers.
The project will test the full chain on CO₂ from a real flue gas stream at EEW's Eschbach site; earlier, the steps were shown in a 2020 experimental unit.
PETRONAS Lubricants International and Turin-based i-TES unveiled thermal batteries in Santena that store waste heat in phase change materials, for industry, buildings and data centers.
A battery-free brush with piezoelectric PVDF bristles reduced dental plaque more than nylon in a three-month trial. It was compared only with manual brushes.
Intensity cycling added to transient scattering microscopy isolates single-particle transport in van der Waals semiconductors and tracks exciton–exciton annihilation in lab experiments.
In laboratory shock experiments, different zones of the same grain changed differently at identical pressure, so missing shock features do not rule out past impact exposure.
The Ministry of Industry of Yakutia reported the first blue diamond of this type mined at a Russian deposit. The crystal contains boron and has no internal inclusions.
Hong Kong Polytechnic University researchers found that uneven charge losses between neighbouring grains speed up light ageing; an additive slowed it in small lab cells.
Chinese researchers found γ-Fe, a high-temperature iron phase not previously documented in lunar samples, preserved at ambient temperature as nanoparticles with a magnetic vortex state.
A material flow analysis of China's PV fleet installed in 2000–2025 puts the retired-module silver peak nine years before the peak of retired capacity, which matters for planning recycling.
Empa's polymer fiber with a liquid insecticide core releases the agent through its sheath and suits compounds that evaporate when heated. Large-scale tests are still needed.
Intensity cycling in a transient scattering microscope lets researchers image single-particle and multi-particle transport separately in van der Waals semiconductors, the authors report.
A spin-cast perovskite film conducts heat at about 0.04 W/(m·K) yet has a 7.7 GPa modulus, above most plastics, foams and aerogels. It is still a lab sample.
A flip-chip packaged gallium oxide module handled pulsed 1000 V, 1000 A switching, raising ultra-wide bandgap power capacity by over two orders of magnitude, the authors report.
