The Role of Hydrogen Bonding in Alkali Metal Ion Solvation
In addition to the experimental measurements, RRKM/Evaporative ensemble calculations were performed on $\rm Na\sp+(CH\sb3OH)\sb{1-9}$ ion clusters to determine the internal energy distributions of the ion clusters in the ion beam as a function of cluster size. It was found that the vibrational …

Elucidation of Battery Electrolyte Coordination Sphere Thermodynamics via Calorimetric and Potentiometric Titrations
… metal-anode batteries are a promising post Li-ion battery development. However, the high reactivity of metallic anodes with the electrolyte results in the formation of a solid-electrolyte interphase (SEI). Electrolyte design is a key handle in controlling the SEI composition in metal-anode …

Ion Aggregation, Correlated Ion Transport and the Double Layer in Super-Concentrated Electrolytes
… are well known and their mathematical descriptions are well established. The physical picture of dilute electrolytes, in which ions are pristinely solvated, fully dissociated, and immersed in an excess of structureless solvent medium, lends itself naturally to elegant and tidy mathematical …

Mechanism of fluoride-based etch and clean processes
Fluoride-containing solutions are widely used to etch silicon dioxide-based films. A critical issue in integrated circuit (IC) and microelectromechanical systems (MEMS) fabrication is achievement of adequate selectivity during the etching of different film materials when they are present in …

Drift Tube Ion Mobility Measurements for Thermochemistry, Kinetics and Polymerization of Cluster Ions
In this work, the Drift Tube Ion Mobility technique is used to study the hydrophobic hydration and solvation of organic ions and measure the thermochemistry and kinetics of ion-molecule reactions. Furthermore, an exploratory study of the intracluster polymerization of isoprene will be presented and …

Infrared spectroscopy of ion-hydrocarbon clusters
Many biological and environmental systems contain ion, water, and hydrophobic components; and it is the balance between these competing interactions which governs their chemistry. This Thesis aims at exploring ion•••hydrocarbon interactions, then ion•••water•••alkane interactions. To accomplish …
