Tech Xplore / Building hypersonic planes won't demand a significantly different design approach, study suggests
Hypersonic planes could fly from Sydney to Los Angeles in just an hour. What's standing in the way of such ultra-fast planes becoming reality is our understanding of how the turbulence they generate as they fly at such high ...
Tech Xplore / The next frontier in clean flight? Jet fuel from city waste
Aviation currently contributes about 2.5% of total global carbon emissions, and with air travel demand expected to double by 2040, cutting those emissions has become a pressing priority. One path forward is sustainable aviation ...
Tech Xplore / Overestimated semiconductor performance metrics: Researchers uncover main culprit
A research team affiliated with UNIST has uncovered a critical flaw in the performance evaluation metrics that have long guided researchers in semiconductor development. This discovery raises concerns that the commonly used ...
Tech Xplore / Morphing 3D-printed structures from flat to curved—in space
Because it's costly and cumbersome to transport large structures such as satellite dishes into space, aerospace Ph.D. student Ivan Wu and his advisor, Jeff Baur, at The Grainger College of Engineering, University of Illinois ...
Tech Xplore / Feeling is believing: Making prosthetic limbs and virtual reality feel more real
Virtual reality and prosthetics are advancing rapidly thanks to technological innovations, but both are still missing one key element—a sense of touch, also known as haptic feedback.
Tech Xplore / Flexible display cools surfaces, offering energy-efficient alternative to traditional signs
Electronic signs are all around us, giving directions or advertising the latest gadget. In ACS Energy Letters, researchers report that they've developed a dynamic display technology that dissipates heat instead of generating ...
Tech Xplore / Mapping AI's brain reveals memory and reasoning are not located in the same place
Researchers studying how large AI models such as ChatGPT learn and remember information have discovered that their memory and reasoning skills occupy distinct parts of their internal architecture. Their insights could help ...
Tech Xplore / Porous separators boost efficiency of electrolyzers for carbon monoxide reduction
Electrolyzers, devices that use electricity to drive desired chemical reactions, could enable the production of clean hydrogen (H2) gas from water (H2O) and the conversion of carbon dioxide (CO2) into useful fuels or industrial ...
Tech Xplore / Mind readers: How large language models encode theory-of-mind
Imagine you're watching a movie, in which a character puts a chocolate bar in a box, closes the box and leaves the room. Another person, also in the room, moves the bar from a box to a desk drawer. You, as an observer, know ...
Tech Xplore / Once considered quality problems, substrate defects now enable precise control of semiconductor crystal growth
A team led by researchers at Rensselaer Polytechnic Institute (RPI) has made a breakthrough in semiconductor development that could reshape the way we produce computer chips, optoelectronics and quantum computing devices.
Tech Xplore / Spray 3D concrete printing simulator boosts strength and design
Concrete 3D printing reduces both time and cost by eliminating traditional formwork, the temporary mold for casting. Yet most of today's systems rely on extrusion-based methods, which deposit material very close to a nozzle ...
Tech Xplore / Fractal-based metamaterial improves sound fields in car cabins
Car enthusiasts will pay hundreds of dollars for stereo systems that will improve the sound quality in their cars. However, the inherent directionality of speakers and complex shapes of car cabins can exacerbate sound disparities ...
