An active optical intensity interferometry scheme enables synthetic aperture imaging from over a kilometer away Intensity interferometry is a promising technique that enables the precise measurement of spatial properties (i.e., distances, shapes and light properties) by probing fluctuations in the intensity (i.e., brightness) of light, as opposed to the exact timing and phase of light…

Just 2% of tidal and offshore solar energy could make a dent in carbon dioxide emissions Harnessing just 2% of the energy potential from tidal and offshore solar sources could make a significant dent in global CO2 emissions, new research has found. Go to techxplore

Sustainable, low-cost batteries for the electric vehicles of tomorrow At a time when electrified vehicles and stationary energy storage play key roles in the climate-neutral future of the energy sector, sustainable production of lithium-ion batteries is essential. A team of researchers headed by Benjamin Schumm, Holger Althues and Stefan Kaskel has developed DRYtraec (dry transfer…

New method enables sustainable recycling of rare earths from electrolyzers Hydrogen electrolysis cells contain rare earth metals. Once an electrolysis cell has done its job, the materials used in it currently end up as scrap steel. A research team at TU Bergakademie Freiberg is now investigating how the recyclable materials can be recovered from used…

AI stirs up the optimal recipe for sustainable concrete For weeks, the whiteboard in the lab was crowded with scribbles, diagrams, and chemical formulas. A research team across the Olivetti Group and the MIT Concrete Sustainability Hub (CSHub) was working intensely on a key problem: How can we reduce the amount of cement in concrete…

New prospects for green ammonia: Study provides blueprint for load-flexible production plant Converting ammonia production to a low-emission process is one of the major challenges in the fight against climate change. Ammonia, one of the most widely produced chemicals worldwide, is essential for the fertilizer industry and, in turn, the production of plant-based foods. However,…

AI-augmented models improve chemical grouting predictions in complex soils Soil liquefaction—the process where saturated soil loses its structure and transforms to a fluid-like state—can have devastating outcomes, as evidenced by the Great East Japan Earthquake in 2011. Large-scale liquefaction during this disaster damaged thousands of houses in the Tokyo Bay area, posing a formidable challenge…

Ultra-thin protective coating boosts cadmium telluride solar cell performance by 13% An NYU Tandon-led research team has developed a novel technique to significantly enhance the performance of cadmium telluride (CdTe) solar cells. Unlike conventional silicon panels that use thick layers of silicon, these solar cells use a simpler, less expensive approach—depositing an ultra-thin layer of…

Dehydration warning at your fingertips: Touchscreen tech tracks body water levels The holy month of Ramadan is a sacred time when millions of Muslims around the world embark on a profound spiritual journey of fasting, prayer, and reflection. But it is also a time when many face serious health risks, as going without food or…

Novel elastic alloy achieves 20x temperature change and 90% Carnot efficiency in solid-state heat pumping Researchers at the School of Engineering of the Hong Kong University of Science and Technology (HKUST) have developed a novel elastic alloy called Ti78Nb22, which achieves remarkable efficiency for solid-state heat pumping and exhibits a reversible temperature change (ΔT) ability…

Proposed wave energy park could generate power while shielding Portuguese coastline A study by researchers from the Interdisciplinary Center of Marine and Environmental Research (CIIMAR) and the Faculty of Engineering of the University of Porto (FEUP) analyzes the potential and feasibility of a wave energy converter park off the coast of Esposende, Portugal, with the…

Golden Dome: An aerospace engineer explains the proposed nationwide missile defense system President Donald Trump announced a plan to build a missile defense system, called the Golden Dome, on May 20, 2025. The system is intended to protect the United States from ballistic, cruise and hypersonic missiles, and missiles launched from space. Go to techxplore

Property owners urged to take action as study reveals overlooked flood risks The risk of heavy rainfall and severe flooding increases with climate change. But property owners—regardless of size—often underestimate their own responsibility and are unaware of what preventive measures they can take themselves. In a new scientific article, researchers from Linköping University, Sweden, show…

A new approach could fractionate crude oil using much less energy Separating crude oil into products such as gasoline, diesel, and heating oil is an energy-intensive process that accounts for about 6% of the world’s CO2 emissions. Most of that energy goes into the heat needed to separate the components by their boiling point. Go…

Metal fleeces boost battery energy density by enabling thicker, faster-charging electrodes Batteries are becoming more and more powerful. A discovery by researchers at the Max Planck Institute for Medical Research in Heidelberg could now give them a significant energy boost. Go to techxplore

New metamaterial enables remote movement of objects underwater using sound Sound can do more than just provide a nice beat. Sound waves have been used for everything from mapping the seafloor to breaking apart kidney stones. Thanks to a unique material structure, researchers can now move and position objects underwater without ever touching them directly.…
