Ion Parking during Ion/Ion Reactions in Electrodynamic Ion Traps

Analytical Chemistry, 2001
Under appropriate ion density conditions, it is possible to selectively inhibit rates of ion/ion reactions in a quadrupole ion trap via the application of oscillatory voltages to one or more electrodes of the ion trap. The phenomenon is demonstrated using dipolar resonance excitation applied to the end-cap electrodes of a three-dimensional quadrupole ...

Fast inelastic ion-ion, ion-electron, and ion-positron collisions

Physical Review A, 1993
We present scaling relations for the total cross sections and collision strengths of bound-state excitation in positive ions. The colliding particle can be positively or negatively charged and can be a fully ionized atom, an electron, or a positron.

Ion-Ion Interactions

1970
A model has been given for the breaking-up of an ionic crystal into free ions which stabilize themselves in solution with solvent sheaths. One central theme guided the account, the interaction of an ion with its neighboring water molecule.

Extraction and Acceleration of Ions from an Ion-Ion Plasma

AIP Conference Proceedings, 2011
Extraction and acceleration of positive and negative ions from a strong electronegative plasma and from an ion‐ion plasma is investigated in the PEGASES thruster, working with SF6. The plasma is generated in a cylindrical quartz tube terminated by metallic endplates.

Ion-Ion Collisions and Ion Storage Rings [PDF]

open access: possiblePhysica Scripta, 1988
Improved understanding of fundamental ion-ion interactions is expected to emerge from research carried out with ion storage rings. In this short survey the significant advantages and unique features that make stored ions useful targets for collision experiments are reviewed and discussed.

Ion-Ion Interactions

2001
Describe and give examples of ionophore, ionogen, strong and waek electrolyte. Why is the charge density around a reference ion not zero when the whole solution is electroneutral? Explain succinctly the Debye-Huckel approach to their ionic-cloud theory.

Ion–Ion Collisions Involving Fullerene Ions

Fullerenes, Nanotubes and Carbon Nanostructures, 2005
Abstract Fullerenes are a direct link between atoms with discrete electronic energy levels and solids with a band structure and a well defined surface. In collision experiments, both between energetic ions or electrons and neutral C60 molecules [Walch, B.; Cocke, C.L.; Voelpel, R.; Salzborn, E.

Ion-Ion Neutralization.

1982
Abstract : A variable-temperature FALP/SIFT apparatus has been built which combines the essential features of the versatile Flowing Afterglow/Langmuir Probe (FALP) and Selected Ion Flow Tube (SIFT) apparatuses. It has been used to determine the coefficients for the recombination reactions of NO+ and 02+ ions with electrons over the temperature range ...

Ion-Ion Interactions

1998
If a potential electrolyte is added to an aqueous solution, it is conceivable that its dissociation may be so low that few ions are produced. It is also possible to make a solution from a true electrolyte so dilute that the number of ions in solution is very small. In both of these cases, the analysis completed in the previous chapter would be adequate
