Proton transfer is ubiquitous in chemistry and biology, occurring, for example, in proteins, enzyme reactions and across proton channels and pumps. However, it has always been described in the context ...

In 2009 researchers found an "ionization surprise" that defied explanation. Until that time, it had been commonly thought that the ionization of atoms by strong laser fields was well-understood, but ...

Light interacting with hydrogen atoms enclosed in hollow cages composed of carbon atoms produces ionization. This phenomenon is particularly interesting because the light rays can have dramatic ...

To break free from an atom, the negatively charged electron typically has to absorb a high-energy photon, such as that from the ultraviolet (UV) or x-ray spectrum. The electron then gets excited ...

Researchers have for the first time measured the first ionization energy of lawrencium, the last of the actinides, validating predictions of the element’s electronic structure (Nature 2015, DOI: ...

Ionization systems, installed in medical device manufacturing facilities’ gown-up rooms and product transfer areas have proven to be critical components in reducing particle counts in the associated ...

In a step toward steering electrons inside molecules to control chemical reactivity, researchers report following electron-hole migration in iodoacetylene (H–C≡C–I) with 100-attosecond resolution ...

The best-laid plans of MICE and muons did not go awry: Physicists at the International Muon Ionization Cooling Experiment, or MICE, collaboration have achieved their yearslong goal of quickly sapping ...
