Tech Xplore / Fast-charging lithium-sulfur batteries on the horizon
New research shows that the next generation of lithium-sulfur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case. The paper is published in the journal ...
Tech Xplore / Sun and space: Harnessing cold universe and solar power for renewable energy
As traditional energy methods increase in cost and take their toll on the environment, Penn State researchers are turning to two underutilized renewable resources, the sun and outer space, for solutions to generate electricity ...
Tech Xplore / Perovskite solar cells: Vacuum process may offer a short track to commercialization
Research and industry worldwide work on the commercialization of perovskite photovoltaics. Most research laboratories focus on solvent-based manufacturing processes because these methods are versatile and easy to use. Established ...
Tech Xplore / Researchers help robots navigate efficiently in uncertain environments
If a robot traveling to a destination has just two possible paths, it needs only to compare the routes' travel time and probability of success. But if the robot is traversing a complex environment with many possible paths, ...
Tech Xplore / Intel introduces approach to boost power efficiency, reliability of packaged chiplet ecosystems
The integration of electronic chips in commercial devices has significantly evolved over the past decades, with engineers devising various integration strategies and solutions. Initially, computers contained a central processor ...
Tech Xplore / From recurrent networks to GPT-4: Measuring algorithmic progress in language models
In 2012, the best language models were small recurrent networks that struggled to form coherent sentences. Fast forward to today, and large language models like GPT-4 outperform most students on the SAT. How has this rapid ...
Tech Xplore / Engineering team discovers new high-performance solar cell material
A Dartmouth Engineering-led study published in Joule has reported the discovery of an entirely new high-performance material for solar absorbers—the central part of a solar cell that turns light into electricity—that ...
Tech Xplore / Study finds rerouting of airplanes to reduce contrails not as expensive as thought
A small team of environmental scientists has found via simulations that rerouting commercial airplanes to reduce contrails would be less expensive than previously thought. In their study, published in the journal Environmental ...
Tech Xplore / New 'papertronics' offer biodegradable alternative to traditional circuits
As the Internet of Things connects more devices into a collective network—even single-use sensors like food packaging, agriculture or "smart bandages"—the need for biodegradable electronics grows increasingly urgent.
Tech Xplore / A quadrupedal robot can do parkour and walk across rubble
The robot known as ANYmal has, for some time, had no problem coping with the stony terrain of Swiss hiking trails. Now researchers at ETH Zurich have taught this quadrupedal robot some new skills: It is proving rather adept ...
Tech Xplore / Wearable stretchable electronics: A new design and fabrication process for skin-like integrated circuits
Small wearable or implantable electronics could help monitor our health, diagnose diseases, and provide opportunities for improved, autonomous treatments. But to do this without aggravating or damaging the cells around them, ...
Tech Xplore / Scientists use novel technique to create new energy-efficient microelectronic device
A breakthrough could help lead to the development of new low-power semiconductors or quantum devices.
