Although liquids are ubiquitous, many basic questions about them remain unanswered. Maria is part of a research effort aimed at determining the structure of liquid - vapor interfaces at a molecular level. The surface structure of liquids is not characterized at a level of detail comparable to established studies of solids and gases, as the experimental techniques needed to do this are only now being developed.

The Hemminger group employs x-ray photoelectron spectroscopy to probe the distribution of ions at the surface of electrolyte solutions. Previous studies in the group have established that certain anions segregate to the surface of aqueous alkali halide solutions. We hope to extend this work to the study of non-aqueous and mixed-component liquids in order to better understand the mechanisms of anion surface segregation. High surface area droplets, known as aerosols, are widespread in the atmosphere and often contain dissolved ions. As a result, understanding the surface structure of electrolyte solutions can have important implications for the heterogeneous chemistry of the atmosphere.

Much of this work is done at the Advanced Light Source in Lawrence Berkeley National Laboratory, in collaboration with several scientists there.
