DNA computers can use biological material to perform mathematical functions and store information, but their power sources have been fragile. Researchers now say they’ve developed a reliable source: ...

A new solid-state battery features an electrolyte (purple, center) sandwiched between two electrodes (blue and silver spheres). The electrolyte, which shuttles hydride ions (H – ...

Though it might seem like science fiction, scientists are working to build nanoscale molecular machines that can be designed for myriad applications, such as "smart" medicines and materials. But like ...

Scientists have built the first rechargeable hydride ion battery. Hydride ions (H⁻) have drawn interest as potential charge carriers for future electrochemical devices because of their extremely low ...
