Trace gas sensors are based on optothermal detection and use a modulated laser source and a quartz tuning fork amplifier to detect small amounts of gases for disease diagnosis via breath analysis and monitoring of atmospheric pollutants and greenhouse gases. We introduce the first mathematical model of a resonant optothermoacoustic sensor. The m...

Two-phase gas-liquid flows are important in a variety of heat transfersystems, such as in the on-chip cooling of microelectromechanicaldevices up to the infrastructure of safety systems in nuclear powerplants. We focus on the case of two-layer flows in inclined channels,where a gas and a liquid, immiscibly separated by a sharp interface withlarg...

This talk will describe recent work in my group by Brian Radak, Scott Yockel and Dongwook Kim concerned with modeling the dynamics of reactions at the gas/liquid interface using a QM/MM approach. The reactions involve atomic oxygen and atomic fluorine collisions with liquid squalane, which is a hydrocarbon polymer, at hyperthermal energies (0.5-...
