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.
Zoomlion claims 1,600 hp combined output from a diesel and an 800 V hybrid system; the John Deere 9RX 830 peaks at 913 hp. Engine and battery specifications are undisclosed.
The 5 MW and 0.5 MW flywheel pair responds in under 100 ms, the company says. It is meant for frequency control at a coal-fired plant in Gansu province.
Semi-transparent panels passing 13.2% and 19.2% of photosynthetically active light delayed maturity, but fresh biomass matched open-field plants.
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.
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.
General Atomics physicists recorded plasma heating by helicon waves at DIII-D, a method meant to let tokamaks run longer without recharging the solenoid.
The Australian companies will build a body-mounted panel with copper-metallised HJT cells and test it in thermal vacuum. SMC says Australian programs now import arrays.
Tesla is studying a laser that clears only the windshield area in front of a self-driving camera; an updated patent was granted on 31 March.
The company will show a scale model of the 800 V cell-to-pack system with 3C continuous power, scalable from tens of kWh to several MWh, at Metstrade in Amsterdam.
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.
Uniper and VNG H&V have produced the first green hydrogen at the 30 MW electrolyser in Bad Lauchstädt. Joint testing of the whole chain now begins; industrial use is planned from 2027.
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.
Italian firms Altimax and Ampr presented a sewer cleaning truck on a Piaggio Porter Npe base, where one battery drives both the vehicle and the pump. No sale date yet.
The turbine at the Emsland gas power plant runs on hydrogen, natural gas or any mix of the two. Tests with up to 100% hydrogen are planned over the coming months.
The Xuwei complex pairs Hualong One and high-temperature gas-cooled Chilong-1 reactors to deliver 32.5 million tonnes of steam a year to petrochemical plants.
The remotely piloted HyLighter will fly over up to 1,600 km of pipelines between Nantes and Quimper until 13 November 2026 in a trial campaign.
