Tech Xplore / Solid-state material can store and release hydrogen using sunlight or LEDs
Hydrogen, a clean energy source, requires a highly reliable and safe storage system, which is currently lacking. Layered hydrogen silicane (L-HSi) is a promising, safe, lightweight, and energy-efficient solid-state hydrogen ...
Tech Xplore / An ultrathin coating for electronics looked like a miracle insulator, but a hidden leak fooled researchers
When your winter jacket slows heat escaping your body or the cardboard sleeve on your coffee keeps heat from reaching your hand, you're seeing insulation in action. In both cases, the idea is the same: keep heat from flowing ...
Tech Xplore / New memristor training method slashes AI energy use by six orders of magnitude
In a Nature Communications study, researchers from China have developed an error-aware probabilistic update (EaPU) method that aligns memristor hardware's noisy updates with neural network training, slashing energy use by ...
Tech Xplore / A new approach to energy harvesting opened up by the quantum world
Touch the back of a laptop and it often feels warm. This is because part of the energy used for computation and communication escapes to the outside as heat. Yet even this "waste heat" still contains a great deal of usable ...
Tech Xplore / Soft robotic hand 'sees' around corners to achieve human-like touch
To reliably complete household chores, assemble products and tackle other manual tasks, robots should be able to adapt their manipulation strategies based on the objects they are working with, similarly to how humans leverage ...
Tech Xplore / OpenAI introducing ads to ChatGPT
OpenAI announced Friday it will begin testing advertisements on ChatGPT in the coming weeks, as the wildly popular artificial intelligence chatbot seeks to increase revenue to cover its soaring costs.
Tech Xplore / Tougher solid electrolyte advances long-sought lithium metal batteries
A solid—rather than liquid—electrolyte between the opposite electrodes of a battery should, in theory, enable a rechargeable lithium metal battery that is safer, packs much more energy, and charges considerably faster ...
Tech Xplore / New RoboReward dataset and models automate robotic training and evaluation
The advancement of artificial intelligence (AI) algorithms has opened new possibilities for the development of robots that can reliably tackle various everyday tasks. Training and evaluating these algorithms, however, typically ...
Tech Xplore / Soft, 3D transistors could host living cells for bioelectronics
New research from the WISE group (Wearable, Intelligent, Soft Electronics) at The University of Hong Kong (HKU-WISE) has addressed a long-standing bioelectronic challenge: the development of soft, 3D transistors.
Tech Xplore / Sub-zero green freezer achieves zero emissions
Researchers at the School of Engineering of The Hong Kong University of Science and Technology (HKUST) have developed the world's first sub-zero Celsius elastocaloric freezing device, capable of reaching temperatures as low ...
Tech Xplore / Novel thick electrode enhances battery power and capacity for a 75% increase in output
A research team affiliated with UNIST has unveiled a new type of thick electrode aimed at solving a common challenge in battery design: As the capacity increases, power often decreases. This breakthrough could enable electric ...
Tech Xplore / AIs behaving badly: An AI trained to deliberately make bad code will become bad at unrelated tasks, too
Artificial intelligence models that are trained to behave badly on a narrow task may generalize this behavior across unrelated tasks, such as offering malicious advice, suggests a new study. The research probes the mechanisms ...
