This is actually quite impressive, and I'm left wondering if similar engineering ideas here would work to create a combination Raman shift and XRD/XRF spectroscopy solution.
Since I am working in the XRD/XRF/XAS space, what are the multimodal techniques that you see as the most beneficial ones to complement the x-ray measurements? If you can tell, I would also be interested what your field of research is :)
