Exploratory Synthesis Of New Open-Framework Iron (Ii,Iii)-Containing Polyanion Systems Targeted For Lithium-Ion Battery Applications, Gregory Becht Aug 2008

Exploratory Synthesis Of New Open-Framework Iron (Ii,Iii)-Containing Polyanion Systems Targeted For Lithium-Ion Battery Applications, Gregory Becht

All Dissertations

The chemistry demonstrated in this dissertation is concerned with the synthesis, structure, properties and applications of inorganic solids containing iron(II,II) redox centers. The endeavor in exploratory synthesis is due largely to the employment of molten salt fluxes such as alkali metal chloride. These halide-fluxes act in two parts; 1) as a solvent to lower the reaction temperature and 2) as an in situ source of unavailable alkali oxides through metathesis reactions. Using these halide fluxes has allowed for the discovery of several new transition metal-containing phosphates, arsenates, and vanadates for a structure/property correlation study. From this study the selected compounds …


Exploratory Synthesis Of Plyanion-Based Open-Framework Solids As Potential Candidates For Cathode Material Applications, Adam Siegfried May 2008

Exploratory Synthesis Of Plyanion-Based Open-Framework Solids As Potential Candidates For Cathode Material Applications, Adam Siegfried

All Theses

This thesis is concerned with exploratory synthesis of polyanion based open-framework solids that can potentially be used as cathode materials in lithium batteries. Two silver manganese vanadates were discovered, Ag3Mn(VO4)2 and AgMn2V3O10, which show different possibilities as cathode materials for primary battery applications; the former contains a higher (Ag+Mn)/V ratio, which is sought for high capacity devices, while the latter may prove better for lower power devices. The structures of the two materials differ in that Ag3Mn(VO4)2 is a layered material where as AgMn …


Exploratory Synthesis And Characterization Of New Mixed-Framework Chalcohalides And Oxyhalide And Its Potential Applications For Diluted Magnetic Semiconductor, Lei Wang May 2007

Exploratory Synthesis And Characterization Of New Mixed-Framework Chalcohalides And Oxyhalide And Its Potential Applications For Diluted Magnetic Semiconductor, Lei Wang

All Dissertations

Due to the excellent diverse properties and performance, solid-state material with low-dimensional crystal structure has always been interested by solid-state scientists. Besides the interesting properties, the low-dimensional-structured materials are used as the platform for further research and application of semiconductor and optical devices, as well as theoretic studies. My dissertation research mainly focuses on two aspects: discovery of solids with low-dimensional crystal structure; fabrication and investigation of new materials using the discovered materials as the platform.
The idea of mixed-anion-framework has been used in synthesis of novel low-dimensional-structured solid-state materials. The stereo-active Sb3+/Bi3+ chalcogenides building units and …


Hydrothermal Crystal Growth Of Oxides For Optical Applications, Colin Mcmillen May 2007

Hydrothermal Crystal Growth Of Oxides For Optical Applications, Colin Mcmillen

All Dissertations

There is great interest in obtaining coherent radiation in all regions of the optical spectrum. This dissertation explores the hydrothermal growth of crystals that function in two regions currently inaccessible by solid state devices. The first gap exists in the deep-UV region, particularly below 200 nm. Some materials such as LBO and BBO can generate coherent light at wavelengths as low as 205 nm. The growth of these materials was explored to investigate the feasibility of the hydrothermal method as a new technique for growing these crystals. Particular attention was paid to the descriptive chemistry surrounding these systems, and several …
