Description:: Metallic conductivity and broken inversion symmetry were long thought to be contraindicated properties, under the assumption that long-range Coulombic interactions (screened by free charge carriers) were necessary for coordinated polar displacements. Within the past decade, the discovery of polar metals has prompted a rethinking of the relationship between metallicity and...

Description:: The work described in this dissertation focuses on the development of a general approach to create nanoscale transition metal chalcogenide materials and new methods for controlling architecture of gold pyramidal structures. In the former, we used chemical nanofabrication, a combination of top-down patterning and bottom-up solid-state synthesis, to achieve control...

Description:: A series of investigations was undertaken to explore the processing and properties of porous titanium with 6 wt% Al and 4 wt% vanadium (Ti-6Al-4V) and an equiatomic nickel-titanium alloy (NiTi). In this study, porous materials were created in the solid state by entrapping argon in a powder compact, and subsequently...
