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.
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.
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.
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.
Under simulated sunlight, a reusable photocatalyst with citric acid leached over 85% of each metal from a mixed NCM/NCA cathode powder. The work is lab-scale, with modeled economics.
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.
A persistent 1-minute oscillation in grid frequency on several continents is linked to synchronized control software in UPS and battery storage. The amplitude has grown in several grids.
Italian startup Sizable Energy completed offshore tests of seabed brine storage, a pumped-hydro analogue at sea. An integrated demonstrator with a data center is scheduled for the first half of 2027.
The company says the S-shaped steel frame cuts rear-side shading by 76% and brings the frame's thermal expansion closer to that of glass than aluminum does.
Bosch Home Comfort Group introduced the York YD series with SEER2 15.2–20 and HSPF2 8.5–10. Cold-climate variants are rated for heating down to −25 C, according to the manufacturer.
