Tech Xplore / Sodium-ion batteries face greater safety hazards due to sodium clusters, study finds
A new study led by the Qingdao Institute of Bioenergy and Bioprocess Technology of the Chinese Academy of Sciences has identified significant safety risks in sodium-ion batteries (SIBs), especially compared to lithium-ion ...
Tech Xplore / Hydrophobic surface coating strategy addresses CO₂ electroreduction stability challenges
The conversion of carbon dioxide (CO2) into valuable chemical products via the electrochemical CO2 conversion reaction could be highly advantageous. This conversion process could help to make good use of excess CO2 in the ...
Tech Xplore / Waste-based perovskite solar cell achieves 21.39% energy efficiency
A team of materials scientists and solar engineers at Nanyang Technological University in Singapore, working with a colleague from Polytechnique Hauts-de-France, has developed a perovskite solar cell using a biomass-based ...
Tech Xplore / High-performance sodium-ion cathode paves the way for lithium-ion battery alternative
For decades, scientists have sought ways to counter our dependence on lithium-ion batteries. These traditional, rechargeable batteries energize today's most ubiquitous consumer electronics—from laptops to cell phones to ...
Tech Xplore / New process gets common rocks to trap carbon rapidly and cheaply
Stanford University chemists have developed a practical, low-cost way to permanently remove atmospheric carbon dioxide, the main driver of global warming and climate change.
Tech Xplore / AI tool creates 3D video game worlds with iterative design
A generative artificial intelligence (AI) tool that could help video game designers to craft gameplay iteratively is presented in a Nature paper. The AI model, developed by researchers at Microsoft, generated robust three-dimensional ...
Tech Xplore / Machine learning accelerates discovery of membranes to filter PFAS from water
Someday, your drinking water could be completely free of toxic "forever chemicals." These chemicals, called PFAS (per- and polyfluoroalkyl substances), are found in common household items like makeup, nonstick cookware, dental ...
Tech Xplore / Bio-hybrid drone uses silkworm moth antennae to navigate by smell
Conventional drones use visual sensors for navigation. However, environmental conditions like dampness, low light, and dust can hinder their effectiveness, limiting their use in disaster-stricken areas. Researchers from Japan ...
Tech Xplore / Flatworm-inspired robot nimbly navigates cluttered water surfaces
Swimming robots play a crucial role in mapping pollution, studying aquatic ecosystems, and monitoring water quality in sensitive areas such as coral reefs or lake shores. However, many devices rely on noisy propellers, which ...
Tech Xplore / Reducing carbon emissions from residential heating: A pathway forward
In the race to reduce climate-warming carbon emissions, the buildings sector is falling behind. While carbon dioxide (CO2) emissions in the U.S. electric power sector dropped by 34% between 2005 and 2021, emissions in the ...
Tech Xplore / Novel 'pruning' technique shows promise for reducing AI bias without harming performance
A method known as "model pruning" can be used to pinpoint and remove neurons that consistently contribute to biased responses, say researchers at the Stanford Law School and the Stanford Institute for Human-Centered AI.
Tech Xplore / Like human brains, large language models reason about diverse data in a general way
While early language models could only process text, contemporary large language models now perform highly diverse tasks on different types of data. For instance, LLMs can understand many languages, generate computer code, ...
