Biological organisms have the extraordinary ability to form mineral structures with unparalleled control. From curved single crystals to hierarchically structured skeletal parts, biomineralization processes produce materials with properties that are highly optimized for their intended applications. These processing techniques occur at ambient conditions using materials abundant in the environment, and...
Transport along and across the grain boundaries of solid-state electrolytes has implications for a broad range of materials and in an equally broad range of technologies. Over the past 2-3 decades, a substantial body of literature has been developed to explain grain boundary transport properties within the context of space...
Oxide/aqueous and metal/metal oxide interfaces are essential for environmental remediation, catalysis, and corrosion inhibition, in addition to their potential implementation as energy transducers, consumer electronics, and coating products. While these interfaces are critically important, they are difficult to access experimentally under aqueous flow conditions. This thesis describes results obtained with...
High performance structural materials are needed for Naval applications which require an excellent combination of yield strength, low-temperature impact toughness, ductility, ballistic-resistance, and weldability. This research investigates precipitation-strengthened HSLA-115 steels and ballistic-resistant 10 wt. % Ni steels, which have emerged as promising alternatives to the widely used HSLA-100 steels for...
In today's rapidly changing world, there is constant demand for the development of new, high performance materials. Fire resistant steels can provide greater safety in the event of a building fire, creep resistant stainless steels can allow for higher power plant efficiency, and cobalt based superalloys have potential for use...
