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.
The companies report a component-level measurement of 7 mdB, about a third of the roughly 20 mdB published in 2025. In photonic quantum computers, photon loss accumulates across switches.
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.
An air-filled core lets light travel at a speed close to 300 thousand kilometres per second, and delay fell by about 30%. The test ran on a specially assembled line, not a live network.
Ring Rover Cam patrols premises on a set route or goes to alarms from other Ring devices; a charge lasts about 30 minutes.
Researchers calibrated a low-cost digital camera to read the infrared electroluminescence of silicon modules and derive open-circuit voltage; tested on eight modules built 1978–2022.
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.
Excavations at Old Dongola in northern Sudan exposed a large staircase and, on an upper level, an unexpected smaller church with Greek-inscribed plaster fragments.
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.
The EU programme splits €440 million in grants and €85 million for a digital platform; early-stage teams can apply for up to €100.000 for proof-of-concept prototypes.
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.
Photon pairs from two independent gallium arsenide quantum dots were used for entanglement swapping in a laboratory setup, a step toward quantum repeaters. Fidelity reached 0.71 with time selection.
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.
Under the IMT-2020 (5G) Promotion Group, test terminals on the Qualcomm X105 modem were checked with ZTE network equipment in uplink and beam-management scenarios.
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.
