An integral part of the transition to green energy is sensibly utilizing the occasional surplus electricity generated by renewable sources. One possibility is using such surplus energy to produce hydrogen via electrolysis. This green hydrogen can then either serve as an energy carrier itself or be used in further synthesis reactions.

The world faces an increasing shortage of housing and an escalating climate emergency. These urgent global issues call for quick action and innovative solutions.

Researchers at the Center for Cognitive Science at TU Darmstadt and hessian.AI have investigated the properties of behavioral economic theories automatically learned by AI.

Researchers from The Hong Kong University of Science and Technology (HKUST) have developed a sensor array design technology inspired by the human auditory system. By mimicking the human ear's ability to distinguish sounds through tonotopy, this innovative sensor array approach could optimize the application of sensor arrays in fields such as robotics, aviation, health care, and industrial machinery.

The constantly growing demand for energy storage is driving research and development in battery technology. The sodium-ion battery is a reliable and affordable replacement for lithium-ion batteries. The easy accessibility and availability of sodium make sodium-ion batteries more attractive and competitive.

A research team consisting of NIMS, the University of Tokyo and the Tokyo University of Science has developed the world's first technique capable of precisely doping an organic semiconductor in an aqueous solution without requiring a vacuum or a nitrogen atmosphere using special equipment.

It's possible to significantly reduce the temperatures of a major city in a hot desert climate while reducing energy costs, a new study by UNSW Sydney shows.

Neural network learning techniques stem from the dynamics of the brain. However, these two scenarios, brain learning and deep learning, are intrinsically different. One of the most prominent differences is the number of layers each one possesses.

NASA and Astrobotic reports that several of the payloads are collecting data in the meantime.

An insight into preventing perovskite semiconductors from degrading quickly, discovered at the University of Michigan, could help enable solar cells estimated to be two to four times cheaper than today's thin-film solar panels.

New lubricants, combined with new knowledge about how they should be applied to train wheels and rails, have the potential to reduce rail sector costs in Norway by hundreds of millions of kroner during the next decade.

Tidal range schemes can protect estuaries and coastal areas from the effects of sea level rise according to a new study by Lancaster researchers.

ChatGPT and other solutions built on machine learning are surging. But even the most successful algorithms have limitations. Researchers from University of Copenhagen have proven mathematically that apart from simple problems it is not possible to create algorithms for AI that will always be stable. The study, posted to the arXiv preprint server, may lead to guidelines on how to better test algorithms and reminds us that machines do not have human intelligence after all.

Newcastle University research is helping shed light on the important interaction between users and remote drivers that oversee the operation of automated vehicles.

Wastewater treatment plants (WWTPs) play a crucial role in environmental protection by mitigating risks to public health and aquatic ecosystems through the prevention of pollutant release. Accurately predicting effluent quality, especially levels of ammonia nitrogen (NH3) and chemical oxygen demand (COD), is essential for ensuring water safety and enhancing the efficiency of WWTPs. Despite advances in data-driven methods, persistent challenges arise from the complexity of wastewater data.

Space-based solar power offers tantalizing possibilities for sustainable energy—in the future, orbital collection systems could harvest energy in space, and beam it wirelessly back to Earth. These systems could serve remote locations across the planet to supplement the terrestrial power transmission infrastructure required today.

Winter storms can easily become billion-dollar disasters as the snow piles up on interstates and collapses roofs and power lines. Yet, while canceled flights and business interruptions can't be avoided, what turns a snowstorm into a disaster often can be.

A new wave of communication technology is quickly approaching and researchers at UBC Okanagan are investigating ways to configure next-generation mobile networks.

Exploring advanced combustion mode with high efficiency and low emissions has been the dream of successive generations of researchers. Conventional diesel engines have high compression ratios thus with thermal efficiencies of 35%–45%, but the diffusion combustion characteristics of diesel make NOx and soot emissions high.

A study of UAB and URV researchers and published in PNAS shows that human beings recognize grammatical errors in a sentence while AI does not. Researchers have compared the skills of humans and the three best large language models currently available.
