Guided ionization waves: Theory and experiments
Physics Reports, 2014 This review focuses on one of the fundamental phenomena that occur upon application of sufficiently strong electric fields to gases, namely the formation and propagation of ionization waves-streamers.

Abstract The titration of ribonuclease, acid to its isoionic point, has been conducted in 1.80 M KCl. The slopes of the titration curves in the neighborhood of half neutralization of the carboxyl groups have been studied at several ionic strengths.

Ionization and double ionization of small water clusters
The Journal of Chemical Physics, 2006The valence ionization and double ionization spectra of the water molecule, of the water dimer, and the cyclic water clusters (H2O)3 and (H2O)4 are calculated by ab initio Green’s function methods and discussed in some detail. Particular attention is paid to the analysis of the development of the spectra with increasing cluster size.

Ionization of nitromethane in the flame ionization detector
Canadian Journal of Chemistry, 1981The mass spectra observed on sampling the unburnt gases of a flame ionization detector to which nitromethane has been added are due mostly to proton transfer reactions of NH4+ and H3O+. These are formed in the reaction zone from the primary ion HCO+, and pass through the unburnt gases to the sampling orifice.

Calcium is the most abundant mineral in the human body. While most of the body's calcium is sequestered in the skeleton, the free, hydrated cation in solution is a key physiologic mediator in a host of metabolic and regulatory processes. The free cation concentration in the extracellular fluid, historically referred to as "ionized calcium" in clinical ...

Physical Review A, 1986
Ion formation in sodium vapor (\ensuremath{\sim}${10}^{11}$ ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}3}$) containing Rydberg atoms (18\ensuremath{\le}n\ensuremath{\le}35) was investigated. Both atomic ions and diatomic molecular ions resulting from collisions between highly excited sodium, ${\mathrm{Na}}^{\mathrm{*}\mathrm{*}}$, and Na(3s) were observed.
