attenuators, filters, transducers and multiple state memory). The types of materials we investigate have potential applications in energy conversion, transparent conducting oxides, gas sensors, catalysts, low temperature co-fired ceramics, dielectric ceramics, solid oxide fuel cells, and electronics (e.g. There is a continual need for: 1) a better understanding of composition-structure-property relationships, 2) new compounds/materials with improved properties, and 3) more economical compounds/materials. The results of the research are presented at conferences and in publications. Group members learn about conducting literature searches and manuscript writing. Measurements of their chemical and properties are conducted using electrical and dielectric characterization as a function of temperature and atmosphere, magnetic measurements, and photocatalytic properties. Characterization of their resulting phase assemblages and crystal structures is conducted through the use of X-ray diffraction techniques and crystallography. Diffractometer measures the angles at which X-rays get reflected and thus get the structural information they contains. Approaches for materials design and discovery include a target approach using structure prediction, a directed approach using chemical intuition and substitutions, and exploratory through phase diagram development. The construction of a simple powder diffractometer was first described by Hull in 1917 1 which was shortly after the discovery of X-rays by Wilhelm Conrad Röntgen in 1895 2. In our research laboratory we utilize various solid state synthesis methods including conventional high temperature (up to 1600 ℃), flux, solvothermal, sealed tube and gas flow reactions. My research group is interested in the synthesis and characterization of solid-state inorganic materials and in fundamental structure/property relationships of solid state oxides.
