Pam and all, I too have been looking at materials using in house lab data. Using an Ag rotating anode (I actually used Ag-k beta for simplicity of the lack of peak splitting) and an MSC curved imaging plate, and very long exposures we got data we found quite useful. However, I stopped playing in that particular corner of the sandbox a while ago to focus on other stuff (more process engineering than materials science related) and would be interested in learning what's new in lab based data.
