Description
Beamtime at the micro XAS/XRF beamline (I18) at Diamond Light Source for ReflEXAFS analyses, funded through Diamond Light Source.
Abstract of proposal:
Summary- Key features of this new proposal:
o Static surface resolved measurements with Np(V) (new PDRA (Dr. P. Bots) competent to do Np work added to team)
o Realistic mixed oxide surfaces studied through use of phlogopite mica single
crystals
o Further exploration of the magnetite surface attachment and monitoring of Fe mediated electron transfer. The rate of reorganization is critical.
o Experiments will be designed to test and augment complementary computational models
These proposed experiments will build on previous real-time adsorbate configuration experiments at DLS for uranium on portlandite and magnetite under conditions representative of a near-field geological disposal facility. In this next set of experiments we will incorporate improvements into our successful in situ methodology.
