The main act of Kang-Kuen Ni’s experiment could fit on the tip of a needle—and it happens in a fraction of a second. The Harvard chemist takes two individual atoms, a sodium and a cesium, each about ...

Collision course: two atoms held in optical tweezers before forming a molecule (Courtesy: Lee Liu and Yu Liu) A single molecule has been created by combining individual atoms of sodium and caesium, ...

Imagine a knot so small that it can’t be seen with the naked eye. Then think even smaller. Chemists have tied together just 54 atoms to form the smallest molecular knot yet. Described January 2 in ...

In a world's first, scientists are able to control a chemical reaction that precisely transforms two atoms into a single molecule. Using laser tweezers, a team of Harvard University scientist nudges ...

A trio of scientists have been awarded the 2025 Nobel Prize in chemistry for developing “metal-organic frameworks,” a form of molecular architecture that packs vast amounts of space into tiny ...

You may make fun, but Ivanka Trump’s very dumb science photo op is actually what most people think when they hear “chemistry.” And it’s not a wrong idea. You mix some chemicals with some other ...

The left image shows a crystal structure of dynamic water molecule cluster like liquid at −20 °C in the supercooled water ...

As electronics continue to shrink, they're constantly pushing up against the limits of our ability to craft increasingly tiny features. Processors rely on features etched with extremely high-energy ...
