Researchers have developed a novel catalyst that enables an aluminum-air flow battery to outperform lithium-ion batteries in terms of energy density, cost, and cycle life. The breakthrough technology uses a silver manganate nanoplate architecture to alleviate side reactions and improve the battery's longevity.
Researchers from Tokyo Metropolitan University have developed a fast and accurate method for estimating local geomagnetic fields using machine-learning techniques. This approach can detect changes caused by earthquakes and tsunamis, enabling unprecedentedly early warnings before these natural disasters strike.
A study found that patients perceive opioids as superior for post-surgical pain relief, despite concerns about addiction and side effects. However, another study showed that opioids are tied to complications after back procedures, including increased pain and poorer quality of life.
A team of physicists has achieved a groundbreaking experiment accelerating electrons to high energies using a new method called plasma wakefield acceleration. This technology has the potential to drastically reduce the size and cost of future particle accelerators.
