ABRC RESEARCH
Investigation 2
Investigation of catalysis at iron-sulfide mineral surfaces in aqueous and gas
phase systems as models of prebiotic chemical transformations. Foci will include:
- Properties of synthetic mineralized surfaces
- The impact of surface defects
and modifications on the physical and catalytic properties of an iron-sulfur
mineral surface
- The effect of energy (photo, redox, thermal, mechanical),
pH, concentration, partial pressure of gases, surface area, and length scale
on the structural, physical, and catalytic properties of iron-sulfur clusters,
particles and minerals, and materials studied by beam/surface collision experiments.
- Spectroscopic analyses and structural modeling of mineral surface defects
by integrated DFT/MO/MM method.
