A single mathematical number determines the shape and size of stalagmites, thus solving a mystery hidden in caves.

At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum ...

Scientists looked at how an electrical charge would move through a barrier of silicon, germanium and tin, part a quantum well. They thought the electrical charge would move more slowly, but mobility ...

Chlorine is an essential industrial chemical used in products ranging from disinfectants to plastics. Yet producing chlorine ...

Inside what looks like a simple block of frozen water, quantum mechanics is quietly rewriting the rules of chemistry. New calculations are revealing how protons tunnel, bonds flicker and molecules ...

When ultraviolet light hits ice—whether in Earth's polar regions or on distant planets—it triggers a cascade of chemical reactions that have puzzled scientists for decades.
