An international team of scientists has found a way to improve battery design that could produce safer, more powerful lithium batteries.

In order to address the challenges in fabrication NiTiNb ternary alloy structures, researchers from Shandong University (SDU) have proposed an alloy design strategy to prepare NiTiNb shape memory alloys (SMAs) through laser powder bed fusion in-situ alloying and post-heat treatment. The in-situ alloyed NiTiNb alloy shows typical transformation characteristics (e.g. wide hysteresis) and good mechanical/functional properties.

University of Toronto researcher Parham Aarabi has created an artificial intelligence model that mimics how people use e-commerce websites—and it may be able to help retailers optimize their sites for people experiencing color blindness and other conditions.

Even though solar home systems are becoming cheaper and easier to access, barriers to their adoption persist among remote communities in developing countries, where solar panels can promote health and education, according to a new study of two rural villages in Ethiopia.

A combined team of engineers from Tsinghua University and the Beijing National Research Center for Information Science and Technology, both in China, has developed a large-scale diffractive hybrid photonic AI chiplet for use in high-efficiency artificial general intelligence applications. Their paper is published in the journal Science.

NASA confirmed Monday that a mystery object that crashed through the roof of a Naples, Florida home last month​ was space junk from equipment discarded by the space station.

Bipolar membranes are a class of ion-conductive polymers comprised of two oppositely charged layers, known as the cation-exchange and anion-exchange layer. These membranes are central to the functioning of various technologies, including electrolyzers and hydrogen fuel cells.

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One challenge is the reconfigurability of optical neural networks.

A team of South Korean scientists led by Professor KIM Dae-Hyeong of the Center for Nanoparticle Research within the Institute for Basic Science has pioneered a novel approach to stretchable displays. The team announced the first development of intrinsically stretchable quantum dot light-emitting diodes (QLEDs).

A team from the Photonics Research Laboratory (PRL)-iTEAM of the Universitat Politècnica de València and the company iPRONICS have designed and manufactured a revolutionary chip for the telecommunications sector, data centers and infrastructure associated with artificial intelligence computing systems. It is the first universal, programmable, and multifunctional photonic chip worldwide.

A new DECHEMA report "Carbon for Power-to-X—Suitable CO2 sources and integration in PtX value chains" deals with possibilities of capturing and utilizing carbon dioxide for sustainable production routes. Carbon dioxide can serve as a carbon feed for numerous climate friendly commodities produced with Power-to-X technologies. The report elaborates on point sources and state-of-the-art capture methods.

Surface Acoustic Wave (SAW) resonators have been widely used in wireless communication below 2 GHz. However, as wireless communication evolves into 5G and 6G, with the new frequency bands above 3 GHz and bandwidth exceeding 500 MHz, conventional SAW technology face serious bottlenecks in terms of high frequency (>3GHz), high quality factor (Q value), and high electromechanical coupling coefficient (k2).

In the evolving Global Navigation Satellite Systems (GNSS) landscape, China's International GNSS Monitoring and Assessment System (iGMAS) stands out for its global monitoring and evaluation of GNSS constellations.

Researchers at Pohang University of Science and Technology (POSTECH) have advanced online security by integrating an AI-based metasurface with oblique helicoidal cholesteric liquid crystals.

When Nebraska Engineering researchers began cooking up new recipes for manufacturing railcar bearing components, they expected there would be a few offerings that wouldn't be as satisfying.

Researchers developing the next generation of computing technology aim to bring some light to the field—literally. Optical computing, which relies on particles of light called photons, is expected to provide alternatives to traditional electronic approaches. Such systems—or light-based components of hybrid systems that also retain electronic parts—could be faster, consume less energy and compute visual information more efficiently through simultaneous, parallel processing.

Thylacines — marsupials known as Tasmanian tigers — were declared extinct decades ago, but efforts to find one in the wild are thriving. Scientists are also working to bring back the species.

Searchers across Tasmania have spent years looking for the extinct Tasmanian tiger while scientists work to try and revive the species.

The studio abruptly shut down today.

A new report led by researchers from UCL finds that the most popular artificial intelligence (AI) tools discriminate against women and people of different cultures and sexualities.
