During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

Using short laser pulses, researchers have imaged the exact moment an ammonia molecule bends and sheds a hydrogen atom.

Unlike the electron beam used in scanning and transmission electron microscopy (SEM, TEM), the beam in a focused ion beam system (FIB) is composed of gallium (Ga) ions. The ions forming the structure ...

Electron capture processes in ion–atom collisions constitute a critical phenomenon in understanding the interplay between charged particles and neutral atoms. In these collisions, an ion may capture ...

Electron impact ionisation processes are fundamental interactions in which an energetic electron collides with an atom or ion, resulting in the ejection of one or more electrons. These mechanisms are ...

AES operates on the principle of the Auger effect, named after the French physicist Pierre Auger. When a material's surface is bombarded with a beam of high-energy electrons or photons, it causes the ...

Researchers extend single-atom electron spin resonance with STM from atoms to molecules, opening the power of synthetic chemistry to engineer their quantum states. Scaling down information devices to ...
