For more than 100 years, scientists have "peered" at atoms in a crystal by analysing the way they scatter X-rays. This process, known as crystallography, reveals the chemical structure of compounds in ...

During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical products. This process entails the movement of both electrons (i.e., negatively ...

German and US scientists recently reported an unusual feat: they observed the world's fastest chemical reaction, during which hydrogen atoms bind onto and then leave a sheet of graphene, all within ...

Plucky atoms: illustration of how light can be used to remove individual gold atoms from a surface. (Courtesy: Baumberg and collegues/Cavendish Laboratory/Department of Physics/University of Cambridge ...

The kinetics of some chemical reactions has been extensively studied with ensemble-averaged methods 1,2. As for the molecular reaction dynamics, only some simple (few atoms) gas-phase elementary ...

The ancient Greek and Indian philosophers who first conjectured that matter was made of tiny little bits of stuff would not believe that now, more than 25 centuries later, we can actually see them.

Platinum is often used as a catalyst to speed up industrial electrochemical reactions, such as those involved in wastewater ...
