“THE inability to balance a chemical equation is a most common difficulty to students of chemistry.” The author has attempted to remedy this very common weakness, and in addition to a concise ...

Researchers developed a machine-learning model that can predict the structures of transition states of chemical reactions in less than a second, with high accuracy. Their model could make it easier ...

Porous media play a critical role in various industrial fields due to their complex pore networks and considerable specific surface areas. The transport and reaction phenomena within porous media are ...

In this video, I explain why some reactions explode while others cool, exploring the root cause of chemical energy. I discuss the chemistry behind endothermic and exothermic reactions, which involves ...

How did life begin? How did chemical reactions on the early Earth create complex, self-replicating structures that developed into living things as we know them? According to one school of thought, ...

A 135-year-old chemistry law is getting a quantum makeover. An experiment with a single quantum bit, or a qubit, has uncovered that the Arrhenius equation, which describes how reaction rates relate to ...
