Rechargeable batteries are everywhere—from portable electronic devices and electric vehicles to renewable energy storage.

If successful, experts will have delivered a nearly limitless energy source without air pollution, long-lasting nuclear waste ...

Scientists in Japan have developed a device that enables external magnetic field control of magnetic injection current in the bulk photovoltaic effect (BPVE), a phenomenon not yet used in commercial ...

It is anticipated that within just a few decades, the surging volume of digital data will constitute one of the world's largest energy consumers. Now, researchers at Chalmers University of Technology, ...

Researchers used ultrathin van der Waals materials to create an electron magnet that can be switched at room temperature. This type of magnet could be used to build magnetic processors or memories ...

This energy management interface is the "brain" of a self-powered, battery-free sensor that can harvest the energy it needs to operate from the magnetic field generated in the open air around a wire.

A group of scientists has created a quantum material where electricity can flow without losing energy as heat. Until now, this was only seen in ...

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings ...

This illustration shows electric current being pumped into platinum (the bottom slab), which results in the creation of an electron spin current that switches the magnetic state of the 2D ferromagnet ...
