Researchers at Tohoku University in Japan have developed a prototype calcium battery with a long cycle life of more than 500 charge-discharge cycles. The battery was developed using a hydride-based ...

Tohoku University researchers have managed to develop a prototype calcium metal battery. The battery is capacable of 500 cycles of repeated charge-discharge. Calcium is widely available and ...

Metallic hydrogen is predicated to be room temperature superconductor simply based on conventional BCS theory. However the pressure required for reaching pure metallic hydrogen is too high to achieve ...

Synthesis reaction of Calcium superhydride under high pressure reproduced by the machine learning model. Here, the surface of calcium hydride (CaH 2) melts to absorb hydrogen molecules, then ordered ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Using extremely high pressures, experimentalists have created many superconducting hydride compounds including one—carbon sulfur hydride (CSH)—that appears to work at close to room temperature.
