Tech Xplore / Exploring sodium batteries down to the atom
Understanding how battery components work at the molecular or atomic levels can help scientists create faster-charging, more powerful, longer-lived storage devices. But the electron microscopes powerful enough to give this ...
Tech Xplore / Targeted data selection could roughly triple AI fine-tuning speed
Can AI fine-tuning that once took 10 hours be completed in just three hours? KAIST researchers have developed a technology that selects the most useful training data and distributes it evenly across multiple GPUs.
Tech Xplore / Redesigning batteries for ultrafast-charging EVs
It's hard to ignore the difference: You can fill a car's tank with gas in mere minutes. Charging the battery of an electric vehicle (EV) can take 30 minutes or more.
Tech Xplore / Tracing the online networks behind AI-generated nude images
As Domestic Violence Awareness Month comes to a close this week, one University of Florida researcher is examining the roots of nudification apps, online platforms that use AI to turn images of clothed people—easily and convincingly—into ...
Tech Xplore / Robot platform combines AI and rapid imaging to improve perovskite solar cell fabrication
Solar cells generate electricity by absorbing sunlight in a thin layer of perovskite, a light-absorbing material. This layer is made with a liquid solution that dries and crystallizes into a solid film, but small changes ...
Tech Xplore / Laden with eggs, robots race up sacred Chinese mountain
Dozens of robots took on more than 3,000 steps up one of China's most famous peaks Monday, carrying eggs and watermelons in a race organizers billed as a test of real-world machine endurance, state media showed.
Tech Xplore / Humanoid AI connects walking and object handling without demonstrations of complete task sequences
A humanoid AI system has been developed that learns jointly from separately collected locomotion and object-manipulation data to perform multiple stages of a task in sequence.
Tech Xplore / How to prepare your online life for your death
What happens to all of your online accounts—credit cards, merchants, news subscriptions, social media, streaming services—after you die? How will your heirs know how to access these accounts or understand what you want done ...
Tech Xplore / Future-proof security system protects Bitcoin Lightning Network from quantum attacks
Nearly all personal information is stored electronically in our digital age. This sensitive data is protected by digital keys unique to each device that would take today's computers billions of years to crack through brute-force ...
Tech Xplore / Infrared-transparent aerogel boosts performance of subambient daytime radiative cooling materials by up to 5.2°C
As global warming continues, people tend to switch on fans or air conditioners during hot weather. But the more we use electrical appliances, the more energy we consume and carbon dioxide we produce. With continuous breakthroughs ...
Tech Xplore / Heated mirror reveals hidden 3D patterns in rising air near a wall
Heat transfer from a heated surface depends partly on the thin layer of air that warms and rises beside it. As this natural convection boundary layer develops, its flow can change from orderly patterns to turbulence, influencing ...
Tech Xplore / Electrolyte redesign unlocks tin's full charge capacity for flow batteries
Tin is able to exchange four electrons as it changes between dissolved ions and solid metal, but acidic tin batteries commonly use only a two-electron reaction, leaving half that potential charge out of reach. Now, researchers ...
