Tech Xplore / Peering inside perovskite: 3D imaging reveals how passivation boosts solar cell efficiency
Perovskite solar cells have garnered widespread attention as a low-cost, high-efficiency alternative to conventional silicon photovoltaics. However, defects in perovskite films impede charge transport, resulting in energy ...
Tech Xplore / Low-cost gelators nearly double the performance of aircraft anti-icing fluids, finds new study
Tiny molecules already used to thicken everyday products like lotions and adhesives may soon help keep aircraft safe in icy conditions. These molecules, known as low-molecular-weight gelators (LMWGs), can self-assemble into ...
Tech Xplore / New robotic skin lets humanoid robots sense pain and react instantly
If you accidentally put your hand on a hot object, you'll naturally pull it away fast, before you have to think about it. This happens thanks to sensory nerves in your skin that send a lightning-fast signal to your spinal ...
Tech Xplore / New AI model accurately grades messy handwritten math answers and explains student errors
A research team affiliated with UNIST has unveiled a novel AI system capable of grading and providing detailed feedback on even the most untidy handwritten math answers—much like a human instructor.
Tech Xplore / New sensor measures strain, strain rate and temperature with single material layer
Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have developed an innovative flexible sensor that can simultaneously detect strain, strain rate, and temperature using a single active ...
Tech Xplore / Passengers' brain signals may help self-driving cars make safer choices
Cars from companies like Tesla already promise hands-free driving, but recent crashes show that today's self-driving systems can still struggle in risky, fast-changing situations.
Tech Xplore / New generator uses carbon fiber to turn raindrops into rooftop electricity
A research team affiliated with UNIST has introduced a technology that generates electricity from raindrops striking rooftops, offering a self-powered approach to automated drainage control and flood warning during heavy ...
Tech Xplore / AI models stumble on basic multiplication without special training methods, study finds
These days, large language models can handle increasingly complex tasks, writing complex code and engaging in sophisticated reasoning. But when it comes to four-digit multiplication, a task taught in elementary school, even ...
Tech Xplore / New ultrathin ferroelectric capacitors show promise for compact memory devices
An ultrathin ferroelectric capacitor, designed by researchers from Japan, demonstrates strong electric polarization despite being just 30 nm thick including top and bottom electrodes—making it suitable for high-density ...
Tech Xplore / Researchers create world's smallest programmable, autonomous robots
Researchers at the University of Pennsylvania and University of Michigan have created the world's smallest fully programmable, autonomous robots: microscopic swimming machines that can independently sense and respond to their ...
Tech Xplore / How ChatGPT could change the face of advertising, without you even knowing about it
Online adverts are sometimes so personal that they feel eerie. Even as a researcher in this area, I'm slightly startled when I get a message asking if my son still needs school shirts a few hours after browsing for clothes ...
Tech Xplore / Unlocking corrosion-free Zn/Br flow batteries for grid-scale energy storage
Scientists have found a way to push zinc–bromine flow batteries to the next level. By trapping corrosive bromine with a simple molecular scavenger, they were able to remove a major barrier to the performance and lifespan ...
