When it is, an electrochemical reaction takes place between the hydrogen and oxygen that directly converts chemical energy into electrical energy. Various types of fuel cells exist, but the one ...

A battery that needs feeding instead of charging? This is exactly what researchers have achieved with their 3D-printed, biodegradable fungal battery. The living battery could supply power to sensors ...

The presence of these oppositely charged ions creates an internal electric field that prevents electrons in the n-type layer to fill holes in the p-type layer. When sunlight strikes a solar cell, ...

A new study published in Science Advances reveals evidence of electrical signaling and coordinated behavior in choanoflagellates, the closest living relatives of animals. This elaborate example of ...

According to many experts, we may soon find ourselves using fuel cells to generate electrical power for all sorts of objects we use every day. A fuel cell is a device that uses a source of fuel ...
