Tech Xplore / Aurivillius-type materials could lower the operating temperature of fuel cells
Fuel cells, devices that generate electricity by converting the chemical energy of hydrogen or other fuels via electrochemical reactions, are promising solutions for powering large electric vehicles, industrial sites and ...
Tech Xplore / ScaFi: A robot that grows like a fish, not a machine—from 2 feet to nearly 10
Propeller-powered underwater vehicles have long helped scientists explore and monitor aquatic environments. But they're limited by their own mechanics: Spinning blades can snag on vegetation, stir up sediment and startle ...
Tech Xplore / Giant cyborg cockroaches could bring supervised care to people trapped beyond rescuers' reach
"Swarms" of cyborg cockroaches with cameras and miniature medical injectors could deliver supervised emergency care to people trapped in collapsed buildings, caves or other places too dangerous for rescuers to reach. The ...
Tech Xplore / AI agents are all the rage—but research shows they leak private data
Before you prompt AI to answer another question or perform another task, a Wake Forest computer scientist wants you to know it could expose your sensitive data.
Tech Xplore / Simulated proving ground trains and assesses AI for actively controlling fluid dynamics
A platform for training and comparing machine learning models to actively reduce drag, improve lift, cut noise and manage heat has been launched by an international team that includes researchers at the University of Washington, ...
Tech Xplore / Using light to distinguish real from fake with hard-to-replicate 'artificial fingerprints'
Shine a light, and the real can be distinguished from the fake. KAIST researchers have developed a security technology that uses unique artificial fingerprints created by the random assembly of nanoparticles. Although extremely ...
Tech Xplore / Amoeba-inspired method could enable energy-efficient hardware for complex optimization
Combinatorial optimization problems are ubiquitous, underpinning decision-making in a wide range of fields, including logistics, transportation, communication networks, drug discovery and materials science. However, these ...
Tech Xplore / AI prevents unstable material designs, cutting costs for chip and cooling applications
Today, anyone with a large enough artificial intelligence model can generate millions of new material designs in minutes. Unfortunately, that hasn't led to a huge leap in the number of new materials being used to improve ...
Tech Xplore / Tri-layer electrolyte improves safety and lifespan of lithium-metal batteries
Lithium metal batteries (LMBs) that use pure lithium (Li) for their negative electrodes are attracting significant attention because of their extremely high theoretical capacity. However, their practical applications are ...
Tech Xplore / Bill Gates warns world unprepared for AI upheaval
Bill Gates warned Wednesday that the world is dangerously unprepared for the upheaval brought by artificial intelligence, with the technology destroying jobs and threatening human connection, especially for young people.
Tech Xplore / Flexible sensor detects near-infrared light with higher response after repeated bending
A research team has developed a flexible near-infrared (NIR) photodetector that delivers photoresponsivity more than five times higher while maintaining its performance under repeated bending. The technology is expected to ...
Tech Xplore / Cesium chloride seed layer helps vacuum-grown tandem solar cells reach 30.3% efficiency
Perovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the ...
