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

Explore the intriguing solution to Maxwell's demon paradox as Rolf Landauer reveals how erasing information generates heat ...

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 ...

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 is one of the most useful concepts in science but also one of the most confusing. This article serves as a brief introduction to the various types of entropy that can be used to quantify the ...

A multi-university research collaboration including Drexel University, Purdue University, Vanderbilt University, the University of Pennsylvania, Argonne National Laboratory, and the Institute of ...
