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.

Adsorption of heavy metal ions by various low-cost adsorbents: a review

International Journal of Environmental Analytical Chemistry, 2020
Environmental pollution, particularly from heavy metal ions in the wastewater, is one of the most serious concerns of the world.

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.

Electrochemical detection of heavy metal ions in water.

Chemical Communications, 2021
Heavy metal ions are one of the main sources of water pollution. Most heavy metal ions are carcinogens that pose a threat to both ecological balance and human health.

Intercalation chemistry of graphite: alkali metal ions and beyond.

Chemical Society Reviews, 2019
Reversibly intercalating ions into host materials for electrochemical energy storage is the essence of the working principle of rocking-chair type batteries. The most relevant example is the graphite anode for rechargeable Li-ion batteries which has been

Electron-Ion, Ion-Ion, and Ion-Neutral Interactions

1990
In my talk, I will present an overview of ongoing work in the area of electron-ion, ion-ion, and ion-neutral reactions. Clearly, this is a very wide field. Rather than trying to cover the whole field, I will focus my discussion on effects which are of importance in high-pressure plasmas, where the “high pressure” regime is defined as that in which ...
