Dialog / Off-the-shelf kitchen chemistry could make Li–S batteries thinner
Demand is booming for batteries that are faster, thinner and cheaper. We want electric cars and bikes that travel further, devices that last longer, charge quicker and cost less. Today, lithium-ion batteries (LIBs) set the ...
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 / Cyberattacks can trigger societal crises, scientists warn
Cyberattacks can wreak havoc on the systems they target, yet their impact often spreads far beyond technical failures, potentially triggering crises that engulf entire communities, a new study argues.
Tech Xplore / Bottleneck in hydrogen distribution jeopardizes billions in clean energy
A study from Edinburgh Business School at Heriot-Watt University found that while hydrogen production, storage and fuel cell technologies are advancing rapidly, the hydrogen distribution infrastructure is developing at half ...
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 / Scientists uncover new quantum state that could power future technologies
Scientists have discovered a new quantum state of matter that connects two significant areas of physics, potentially leading to advancements in computing, sensing and materials science.
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 / ChatGPT's free ride is ending: Here's what OpenAI plans for advertising on the chatbot
OpenAI says it will soon start showing advertisements to ChatGPT users who aren't paying for a premium version of the chatbot.
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 ...
