Tech Xplore / Harvesting hot electrons could break solar panel barrier
Physics predicts that no more than 33% of the solar energy that falls on a solar panel can be converted into electricity. However, experiments and simulations by scientists at the University of Groningen in the Netherlands ...
Tech Xplore / 'Artificial leaf' generates clean hydrogen from contaminated seawater
Scientists from Nanyang Technological University, Singapore, have designed a device that harvests sunlight to generate clean hydrogen from seawater and simultaneously degrades hydrazine, a highly toxic contaminant from industrial ...
Tech Xplore / A robot that shifts its own weight to cross land, steps, and water
A robot meant to inspect a coastline, a flooded street or a wetland can't count on one kind of ground. It might need to crawl over a hard surface, climb a bank, scale a curb or a step, then slide into open water, often within ...
Tech Xplore / Chatbot gives teens first-hand experience of cybergrooming tactics without the risk of harm
Virginia Tech researchers are developing virtual tools to help teens protect themselves against cybergrooming. Using survey data from parents and teens and leveraging artificial intelligence, the research team created a chatbot ...
Tech Xplore / AI still isn't as good at recognizing objects as people are, new test shows
Artificial intelligence has gradually made its way into many areas of life with abilities that often match or surpass those of humans. But a study published in the journal iScience finds that AI-powered machines have trouble ...
Tech Xplore / MRI technique eliminates 'dead time' to capture rapidly fading signals, making scans more precise
A team of researchers at the University of Stuttgart has developed a new method that could make MRI even more precise by eliminating "dead time," a key limiting factor in the measurement process, thereby enabling the detection ...
Tech Xplore / New method can assess interchangeability of chemically different battery types
Southwest Research Institute (SwRI) has developed a new method to determine when sodium-ion (Na-ion) and lithium-ion (Li-ion) battery technologies can provide comparable electrical performance for defined applications.
Tech Xplore / Degrading dopants could boost organic semiconductor charge levels 100-fold
Organic semiconductors are carbon-based materials that can conduct electricity and can be used for flexible, lightweight and potentially low-cost electronic devices. While the technology is promising, performance challenges ...
Tech Xplore / OpenAI flags concerning new AI behavior and vows to track it more closely
OpenAI has disclosed six reports of "unexpected or concerning" behavior in artificial-intelligence models as the debate on AI safety becomes increasingly heated.
Tech Xplore / Engineers create revolutionary new sound effect paradigm by manipulating sound wave interactions
Electronic engineers at Nottingham have found a new way to create sound effects by manipulating the interaction of sound waves, a method that could open new possibilities in music performance and production. It is a novel ...
Tech Xplore / Manuscripts-turned AI agents can now 'talk' to each other and make new discoveries
Since 1665, scholarly journals have served as written records of scientific advancement—static words on a page, references written by people for other people to read. That's about to change.
Tech Xplore / How AI models decide not to answer a question
Large language models (LLMs), the artificial intelligence (AI) systems supporting the functioning of ChatGPT, Gemini and similar conversational platforms, are often expected to answer queries, generate texts for specific ...
