Elaine DiMasi uses synchrotron x-ray scattering techniques to study biological mineralization processes and the sub-micron architectures of the organic-mineral composite materials that are produced. Specialized techniques include liquid surface reflectivity, in-situ surface scattering and microbeam diffraction. Elaine manages beamline X6B and its user program in diffraction and scattering, emphasizing Soft- and Bio-Materials, and supports users from BNL’s Center for Functional Nanomaterials.
