For more than a century, thermodynamics has described how heat flows and engines run, while quantum mechanics has ruled the ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

The unique properties of high-entropy alloys make them ideal for hydrogen storage, offering advantages in stability and ...

If you have a deep-seated, nagging worry over dropping your phone in molten lava, you're in luck. Materials scientists have developed a method for rapidly discovering a new class of materials with ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

Thermodynamic spontaneity—whether a reaction can go—can be measured by changes in either of two parameters: entropy or free energy.
