Gregoire, J. M.
Development of new synchrotron X-ray diffraction and fluorescence methods for rapid characterization of material libraries.
Significance & impact
First demonstration of prototype facility capable of meeting the structural characterization requirements for high-throughput material genomic searchers.

Complex technological requirements demand precisely tailored material functionalities, and materials scientists are driven to search for these new materials in
- High-quality XRD powder patterns of thin film Bi-V-Fe oxide samples were measured
withthroughput better than 18 s per sample.
- The optimal configuration for mapping reciprocal space with a single detector image was designed through simulations of the scattering experiments, yielding the highest throughput characterization of these light absorber libraries.
