Tech Xplore / Designing the heart of hydrogen cars: AI points to zinc as key for stable fuel cell catalysts
In the era of climate crisis, hydrogen vehicles are emerging as an alternative for eco-friendly mobility. However, the fuel cell, known as the "heart of the hydrogen car," still faces limitations of high cost and short lifespan. ...
Tech Xplore / Longer-range electric vehicles: Dry-process electrodes use a lithium film to curb early losses
A research team affiliated with UNIST has unveiled a novel dry-process manufacturing method for thick electrodes aimed at enhancing electric vehicle (EV) driving range while reducing battery production costs. Professor Won-Jin ...
Tech Xplore / Researchers develop pre-seeding strategy for improving inverted perovskite solar cells
Regular perovskite solar cells (PSCs)—which place the electron-transport layer beneath the perovskite absorber and the hole-transport layer on top—have limitations with respect to large-scale manufacturing and stability. ...
Tech Xplore / 'Solar battery' stores sunlight for days, then releases hydrogen on demand
A new material can store energy from sunlight and convert it into hydrogen days later. The material, jointly developed by researchers from Ulm and Jena, can do this even in the dark. The process is reversible and can be reactivated ...
Tech Xplore / Adaptive drafter model uses downtime to double LLM training speed
Reasoning large language models (LLMs) are designed to solve complex problems by breaking them down into a series of smaller steps. These powerful models are particularly good at challenging tasks like advanced programming ...
Tech Xplore / Protecting perovskite solar cells against environmental influences with light-switchable molecules
A team from the University of Stuttgart, together with international researchers, has succeeded in enhancing both the efficiency and environmental resilience of perovskite solar cells. This is another important step toward ...
Tech Xplore / Novel cathode design tames distortions to improve lithium-ion batteries
A battery's positive end (cathode) and negative end (anode) are two vital components that largely define how well it can perform. In particular, researchers have focused on improving the efficacy and cost-effectiveness of ...
Tech Xplore / For solar power to truly provide affordable energy access, we need to deploy it better, say researchers
Small household solar power systems have been gaining traction—and investment—as a means to provide affordable and sustainable energy to those living without access to electricity. But new research led by the University ...
Tech Xplore / Chatbots overemphasize sociodemographic stereotypes, researchers report
People interact with artificial intelligence (AI)-powered chatbots, which can be trained to take on certain demographic attributes like age and race, for information, entertainment, technical help, learning, emotional support, ...
Tech Xplore / Your car's tire sensors could be used to track you
Researchers at IMDEA Networks Institute, together with European partners, have found that tire pressure sensors in modern cars can unintentionally expose drivers to tracking. Over a ten-week study, they collected signals ...
Tech Xplore / Industrial TOPCon solar cells hit 26.66% efficiency record
Crystalline silicon solar cells currently dominate the global photovoltaic industry, with tunnel oxide passivating contact (TOPCon) technology—a type of architecture within this product segment—rapidly gaining market ...
Tech Xplore / How AI could help make society less selfish
The Care Bears taught a generation of kids that sharing is caring, but not everyone has carried this principle into adulthood. Researchers at Michigan State University have found a new angle to promote cooperation: artificial ...
