Spectroscopy as a Probe of the Chemistry and Impacts of Environmental Interfaces

This Pittsburgh Spectroscopy Award Address will focus on spectroscopy as a probe of the chemistry, as well as the impacts, of environmental interfaces. Environmental interfaces are defined as any surface in equilibrium with its surrounding environment. From this broad definition, there are a myriad of different types of environmental interfaces that include atmospheric aerosols, aqueous microdroplets, engineered and geochemical nanomaterials and indoor surfaces. The chemistry of environmental interfaces puts a focus on the molecular and nanoscale level interactions that occur in these inherently complex systems. A broad array of different spectroscopic techniques that can provide insights into these interfaces will be highlighted.
