Topics:
- Materials
- Materials Synthesis from Atoms to Systems
Scientific Achievement
- The effects of porous media on precipitation reactions are shown to be important, but poorly understood.
Significance and Impact
- Geochemical reactions within rocks and soils occur in pores. Yet, there is not agreement on how the pores affect the reactions, which limits the ability ro predict reactions in the subsurface.
Research Details
- The different theories for how precipitation in pores occurs and are reviewed and their significance for macroscopic properties such as fluid transport, porosity, and permeability, are evaluated
- It is demonstrated how X-ray/neutron scattering, combined with computational simulation may allow us to resolve this discrepancy observing geochemical reactions directly within a rock
