Scientists from Pacific Northwest National Laboratory are investigating how hematite and other subsurface minerals react, providing information important to soil evolution, atmospheric chemistry, and waste remediation. In conducting this fundamental research, the scientists conduct experiments using a host of instruments at PNNL and at scientific user facilities (e.g., EMSL) to obtain and analyze atomic-level observations of mineral surface structure and real-time measurements of mineral reactivity in geochemical environments. Research in this area is focused on structures and processes of molecular and nanoscale systems in complex environments, such as in the condensed phase and at interfaces. We study model systems to better understand natural systems and guide the development of new materials and approaches for clean and efficient energy use. Another central feature is developing new experimental and theoretical methods with broad applications to research in the natural sciences. The program in condensed phase and interfacial chemical physics consists of both theoretical elements and experimental elements, including the molecular beam scattering instrument shown here.
