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.

El mundo enfrenta una creciente escasez de viviendas y una creciente emergencia climática.Estos urgentes problemas globales exigen acciones rápidas y soluciones innovadoras.

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.

La creciente demanda de almacenamiento de energía está impulsando la investigación y el desarrollo de la tecnología de baterías.La batería de iones de sodio es un reemplazo confiable y asequible de las baterías de iones de litio.La fácil accesibilidad y disponibilidad del sodio hace que las baterías de iones de sodio sean más atractivas y competitivas.

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.

Las técnicas de aprendizaje de redes neuronales surgen de la dinámica del cerebro.Sin embargo, estos dos escenarios, aprendizaje cerebral y aprendizaje profundo, son intrínsecamente diferentes.Una de las diferencias más destacadas es la cantidad de capas que posee cada uno.

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.

La investigación de la Universidad de Newcastle está ayudando a arrojar luz sobre la importante interacción entre los usuarios y los conductores remotos que supervisan el funcionamiento de los vehículos automatizados.

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.

La energía solar basada en el espacio ofrece posibilidades tentadoras para la energía sostenible; en el futuro, los sistemas de recolección orbitales podrían recolectar energía en el espacio y transmitirla de manera inalámbrica a la Tierra.Estos sistemas podrían servir en ubicaciones remotas de todo el planeta para complementar la infraestructura de transmisión de energía terrestre que se requiere hoy en día.

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.
