A study of optical properties and current emission processes of gas phase field ionization sources
… cannot produce beams of H, He or other noble gases, so that gas field ionization sources (GFIS) could have great utility for microscopy or applications sensitive to metal contamination (such as in-line processing). This dissertation explores the properties of the gas field ionization source …

Fundamental Investigations of Hazardous Gas Uptake and Binding in Metal-Organic Frameworks and Polyurethane Films
… A molecular-level understanding of the nature of gas–surface interactions is critical to the development of next generation materials for applications such as gas storage and separation, chemical sensing, catalysis, energy conversion, and protective coatings. Quartz crystal microbalance (QCM) and …

Time Dependent Uptake of Volatile Organic Compounds on Silica and the Observation and Quantification of Ambient Sesquiterpenes in Virginia
Correlation of adsorption behavior for a gas-surface system to the molecular structure of the gas-phase molecule is necessary to better constrain atmospheric modeling. Despite the variety of compounds emitted into the atmosphere, the role of molecular structure on uptake probability, γ, for a …

Use of molecular dynamics simulations to study the impact of weak to strong non-covalent chemical interactions
… to study the role of van der Waals and Coulomb interactions on two fundamental processes, namely, gas-surface interactions and electrospray propulsion, respectively. For the gas-surface interaction work, we proved that conventionally used gas surface interaction models were not adequate in …
