2. Assoc. Prof. Wayne Pearson
My research interests lie in the development of new protocols to improve accuracy in XRF and SCXRD analyses. Project 1: Development of a System of Scaling Factors to Improve Quantitative Analysis in XRF studies Project 2: Application of Radial Form Factors to Improve Refinements of X-ray Crystal Structures.

6. Ru-Ni complex – surprising photochemical reaction
Photochemical reaction observed for complex with ester-substituted bpy ligands on Ru but not for bpy analogue:
Sarah Duffy USNA ’11
UV-Vis spectrum of the bimetallic complex is not simply the sum of the parts:
Given that the spectra of the two complexes are so similar, why do they react so differently?
Another approach:
Possible route to more robust bimetallic complexes?
Prepare analogues with other metals (e.g. Cu or Pt) at the sulfur site.
Electronic structure?
Doyoung Lee ’14
Possible mechanism involves ET from ligand bridge to the diester-bpy ligands (?)
