Tech Xplore / Electrifying railways cuts black carbon exposure by 89%, study finds
Switching from diesel to electric trains dramatically improved the air quality aboard the San Francisco Bay Area's Caltrain commuter rail line, reducing riders' exposure to the carcinogen black carbon by an average of 89%, ...
Tech Xplore / Living fungus-based building material repairs itself for over a month
Engineers have developed a building material that uses the root-like mycelium of a fungus and bacteria cells. Their results, published in Cell Reports Physical Science, show that this material—which is manufactured with ...
Tech Xplore / 'Hyperadaptor' alloy with stable properties stands strong across extreme temperatures
A research team at POSTECH (Pohang University of Science and Technology) has developed a new alloy that maintains its strength and ductility across extreme temperatures ranging from –196 °C to 600 °C. The findings, which ...
Tech Xplore / From disorder to order: Zero thermal expansion materials rejuvenate aging batteries
A team of scientists have developed zero thermal expansion (ZTE) materials. This innovation has achieved nearly 100% voltage recovery in aging lithium-ion batteries (LIBs). Their study is published in Nature.
Tech Xplore / Concrete in road tunnels decomposes unexpectedly fast
When seawater penetrates concrete in road tunnels, a biofilm is formed that breaks down the concrete. This can lead to high costs and the risk of damage if stone and concrete drop from the tunnel roof. In a new study, led ...
Tech Xplore / Programmable photonic chip uses light to accelerate AI training and cut energy use
Penn Engineers have developed the first programmable chip that can train nonlinear neural networks using light—a breakthrough that could dramatically speed up AI training, reduce energy use and even pave the way for fully ...
Tech Xplore / Self-healing lithium battery stretches, survives punctures and cuts
A multidisciplinary team at the University of California, Berkeley, the Georgia Institute of Technology and the Hong Kong University of Science and Technology has developed a stretchable, self-healing lithium battery that ...
Tech Xplore / Lithium oxide sublimation opens doors for cheaper and quicker battery manufacturing
A common lithium salt has revealed new possibilities for manufacturing cheaper, longer-lasting battery materials.
Tech Xplore / Ambisonics algorithm helps create rich virtual soundscapes using a domed array of loudspeakers
Surround-sound speakers can immerse you in a multimedia experience, but what if there was a speaker that could completely re-create a three-dimensional soundscape?
Tech Xplore / Making desalination more eco-friendly: New membranes could help eliminate brine waste
Desalination plants, a major and growing source of freshwater in dry regions, could produce less harmful waste using electricity and new membranes made at the University of Michigan.
Tech Xplore / Training LLMs to self-detoxify their language
As we mature from childhood, our vocabulary—as well as the ways we use it—grows, and our experiences become richer, allowing us to think, reason, and interact with others with specificity and intention. Accordingly, our ...
Tech Xplore / Smoothing over rough edges in batteries: Discovery could improve device durability
Texas engineers have discovered a new phenomenon in modern batteries, one that could be used to improve their life cycles.
