Físicos del MIT han observado en grafeno cómo los electrones se convierten en fracciones de sí mismos, el denominado efecto Hall cuántico hasta ahora solo observado bajo campos magnéticos muy altos.
Este estado electrónico exótico, visto ahora en una capa de carbono delgada como un átomo que proviene del grafito como la mina de un lápiz, puede permitir el desarrollo de formas más robustas de computación cuántica.
Un estudio liderado por la investigadora Laura Scholz, del Instituto de Astrofísica de Canarias (IAC), halla, por primera vez, evidencias observacionales de que la evolución y propiedades de las galaxias no sólo están condicionadas por la masa de las estrellas que contienen, sino también por el efecto de los halos de materia oscura que las rodean.
Last month, OpenAI chief executive Sam Altman finally admitted what researchers have been saying for years — that the artificial intelligence (AI) industry is heading for an energy crisis. It’s an unusual admission. At the World Economic Forum’s annual meeting in Davos, Switzerland, Altman warned that the next wave of generative AI systems will consume vastly more power than expected, and that energy systems will struggle to cope. “There’s no way to get there without a breakthrough,” he said.
Chinese automotive companies are establishing oceangoing car carrier fleets, also known as Ro-Ro ships, to enhance their export capacity and responding to the trend of China-made vehicles being shipped abroad.
In mid-January, BYD's first car carrier, Explorer No 1, leased from the international shipping company Zodiac Maritime, embarked on its maiden voyage, transporting more than 5,000 new energy vehicles to Europe.
UK-based clean technology group Altilium is collaborating with vehicle salvage and recycling specialist Synetiq to recycle the growing number of EV batteries from damaged cars.
California-based Archer Aviation, a developer of electric vertical takeoff and landing (eVTOL) aircraft, has a Space Act Agreement with NASA for a joint project that will initially focus on studying high-performance battery cells and safety testing for applications in the fields of advanced air mobility (AAM) and space.
Chemical giant DuPont has launched a new glycol-purification solution for e-mobility. DuPont AmberLite EV2X resin is designed to extend the lifetime of EV coolants while reducing glycol maintenance requirements.
Amid the urgent need to combat climate change, the shift towards renewable energy solutions is occurring at a rapid rate, such that the U.S. Energy Information Agency (EIA) suggests renewable energy will meet 35% of global power generation needs by 2025. The acceleration of renewable energy generation is certainly the main development, but the global transition to renewable energy also demands eco-efficient power grids that actively contribute to reducing greenhouse gas (GHG) emissions.
Producing sustainable fuels from solar energy is an ambitious project and presents major challenges to people and material. In the MAfoS project, researchers at the Fraunhofer Center for High Temperature Materials and Design HTL are developing materials for the first industrial solar-to-fuel demonstration plant.
