Next-generation fuel cells may clean themselves during operation
Fuel cells are devices that produce electricity by converting chemical energy directly into electrical energy.
Unlike batteries, which store electricity and eventually run out, fuel...
A strange new material gets smaller when heated—and could transform computer memory
Most materials we use in everyday life expand when they are heated.
Metals, plastics, and many other materials grow slightly larger as the temperature rises...
Why established battery giants still hold the advantage in the sodium-ion era
Sodium-ion batteries are often described as the next big thing in clean energy storage, promising lower costs and freedom from scarce materials like lithium...
Why breakthrough solar cells often fail to reach your roof
Many new energy technologies look impressive in the laboratory but never become real products.
