Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world ...

Compressing hydrogen demands high pressures; liquefying it requires extreme cooling. Both approaches carry energy penalties, safety considerations, and infrastructure costs that limit wider adoption.

A recent study published in Nature Communications introduces a new method to improve lithium-ion battery performance. Researchers applied high-entropy doping (HED) to niobium pentoxide (Nb₂O₅) ...
