This tutorial will explore the principles of desorption electrospray ionization (DESI) mass spectrometry, which has been used to scan across the surface of a tablet, image an untreated tissue ...

Bipolar ionization technology emits charged particles that attach to and deactivate harmful substances like bacteria, allergens, mold, and viruses.

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 ...

A NUMBER of workers have investigated ionization of gases by positive ions of low energies 1–5. They have measured ionization electron current produced by positive ions by their impact with gas ...

Current state of the theory of Penning ionization is reviewed, in terms of the problems currently under consideration, the physical concepts underlying various recent theories, and some of the ...

We used attosecond angular streaking to place an upper limit of 34 attoseconds and an intensity-averaged upper limit of 12 attoseconds on the tunneling delay time in strong field ionization of a ...

It describes options and how to calibrate plane parallel ionization chambers, against air kerma or absorbed dose to water standards at cobalt-60 gamma ray energies. The use of these chambers to ...
