Tech Xplore / Mimosa seed bio-piezoelectric device functions as self-charging supercapacitor with high efficiency
Most energy generators currently employed within the electronics industry are based on inorganic piezoelectric materials that are not bio-compatible and contribute to the pollution of the environment on Earth. In recent years, ...
Tech Xplore / Advanced microelectronics: Why a next-gen semiconductor doesn't fall to pieces
A new class of semiconductors that can store information in electric fields could enable computers that run on less power, sensors with quantum precision, and the conversion of signals between electrical, optical and acoustic ...
Tech Xplore / Solar cell efficiency record achieved with tin halide perovskite
University of Queensland researchers have set a world record for solar cell efficiency with eco-friendly perovskite technology. A team led by Professor Lianzhou Wang has unveiled a tin halide perovskite (THP) solar cell capable ...
Tech Xplore / Predicting material failure: Machine learning spots early abnormal grain growth signs for safer designs
A team of Lehigh University researchers has successfully predicted abnormal grain growth in simulated polycrystalline materials for the first time—a development that could lead to the creation of stronger, more reliable ...
Tech Xplore / RoboBee gets crane fly-inspired legs for soft touchdowns
The Harvard RoboBee has long shown it can fly, dive, and hover like a real insect. But what good is the miracle of flight without a safe way to land?
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 / 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 / A step toward harnessing clean energy from falling rainwater
When two materials come into contact, charged entities on their surfaces get a little nudge. This is how rubbing a balloon on the skin creates static electricity. Likewise, water flowing over some surfaces can gain or lose ...
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 / 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 ...
