Flux Growth of Single Crystal Lead-Titanate and Property Measurements
This thesis is concerned with the crystal growth of lead titanate, and the determination of basic electrical, mechanical and optical properties. Of particular concern is the disruptive phase transformation at approximately 500$\sp\circ$C, and the attainment of large equidimensional crystals free of …

Flux growth, characterization, and structure-property relations for inorganic oxide crystals: Lithium triborate, potassium titanyl phosphate and lead titanate
This thesis is concerned with the crystal growth of three different types of inorganic nonlinear dielectric materials, namely, lithium triborate (LBO), lead titanate (PT), and potassium titanyl phosphate (KTP). The electrical and optical properties were determined and related to their structural …

Forward and inverse metabolic engineering strategies for improving polyhydroxybyrate production
… phaB, acetoacetyl-CoA reductase, limited PHB flux. Beyond this, whole operon overexpression led to even higher PHB fluxes.In a nitrogen-limited chemostat, PHB flux did not change with dilution rate. Unlike prior pleiotropic perturbations, these systematic experiments could clearly conclude …

High-temperature superconductivity in a family of iron pnictide materials
The work in this thesis falls roughly into three parts, which I characterise loosely as a developmental stage, an exploratory stage, and an attempt to contribute to understanding of the field. In the developmental stage, I have worked to design a variety of methods to create high-quality samples of …

Compositional tuning, crystal growth, and magnetic properties of iron phosphate oxide
… The first chapter focuses on single crystal growth of Fe3PO4O3. While neutron powder diffraction provides insight to the magnetic structure, powder and domain averaging obfuscate a conclusive structure for Fe3PO4O3 and single crystal neutron scattering is necessary. Due to the incongruency of …
