Understanding the behavior of materials far from equilibrium is important for a broad range of current and emerging technologies and environmental problems. The instances, which give rise to non-equilibrium, range from melting of superheated crystals to condensation of atmospheric cloud particles. Over the past years, Sadtchenko group has developed and perfected two novel analytical techniques: the Fast Scanning Calorimetry (FSC) and Fast Thermal Desorption-Reaction Mass Spectrometry (FTDR MS). The current focus of the research program at the GWU is two-fold: studies of environmentally relevant molecular dynamics and reactions in polycrystalline ice at temperatures near its melting point by FTDR MS, and FSC investigation of non-aqueous condensed phases by FSC.
