Project Details

Description

Beamtime at the High-Brilliance X-ray Spectroscopy beamline (ID26) at ESRF, funded through ESRF.

Abstract of research proposal:
Recent studies have shown that HERFD-XANES has the potential to be used to study uranium speciation in complex environmental systems. In this study we propose to utilize HERFD-XANES to investigate U oxidation state and speciation in key abiotic and microbial biogeochemical processes, including U interaction with iron oxide minerals, and single culture microbial U reduction.
