(Phys.org) —Although sodium-ion (Na-ion) batteries don't perform as well as lithium-ion (Li-ion) batteries, they have the potential to be a cheaper alternative. In a new study, scientists have designed a new cathode for ...
Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities ...

Researchers from China have confirmed the existence of an approximately 8.5-year Inner Core Wobble (ICW) in both polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the Earth's ...
Scientists have dedicated intense work in recent years to convert environmental energy into electricity to meet the ongoing demands for a cleaner and more sustainable power source. Harvesting environmental mechanical energy ...
