Crystallography, the primary method for determining the 3D atomic positions in crystals, has been fundamental to the development of many fields of science. However, the atomic positions obtained from crystallography represent a global average of many unit cells in a crystal. Here, we report, for the first time, the determination of the 3D coordinates of(More)
Perfect crystals are rare in nature. Real materials often contain crystal defects and chemical order/disorder such as grain boundaries, dislocations, interfaces, surface reconstructions and point defects. Such disruption in periodicity strongly affects material properties and functionality. Despite rapid development of quantitative material characterization(More)
Recent US health reform initiatives now require extensive consumer involvement through healthcare purchasing exchanges. The opportunity exists to monitor and plan for peak service needs in such an environment. The use of computational systems and methods for health services planning and utilization review have traditionally been employed in post-facto or(More)
Nanomaterials appear to be promising for a number of applications in in-vitro diagnostics, mainly due to the biocompatibility, specific surface and conduction activity. The use of nanostructures as diagnostic tools has the advantage of very low limit of detection achievable, high sensitivity, strong selectivity and the possibility to fabricate point-of-care(More)
