Synthesis and structure of new transition metal containing bismuth oxides

Creator:: Xun, Xiumei
Abstract:: Exploratory synthesis is the discovery of new compounds with interesting structures and properties. The subject of this thesis is exploratory synthesis of bismuth containing oxides. Bismuth containing oxides have many interesting properties, which are ionic conductivity, ferromagnetism, superconductivity, ferroelectricity, ferroelasticity and catalytic. These properties are closely related to their specific...

Synthesis and structural determination of alkali and alkaline earth metal containing bismuth vanadates

Creator:: Bliesner, Rebecca J.
Abstract:: Exploratory synthesis plays an important role in the quest to discover new materials. There are very few structurally characterized alkali metal containing bismuth vanadates. Hybridization of the 6s and 6p orbitals of Bi[superscript 3+] and the resulting lone electron pair yields some very interesting stereochemistry and steric related properties. Some...

An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO3 - Bi(Zn1/2Ti1/2)O3, An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃

Creator:: Jackson, Dennis L.
Abstract:: We developed a model to investigate the dielectric properties of the BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃ (BT-BZT) solid solution, which is a relaxor ferroelectric and exhibits long range disorder. The model uses ab initio methods to determine all polarization states for every atomic configuration of 2 x 2 x 2 supercells of...

Development of bi-based lead-free piezoelectric materials : thin film piezoelectric materials via PVD and CSD routes

Creator:: Jeon, Yu Hong
Abstract:: Piezoelectric materials have been widely used in electromechanical actuators, sensors, and ultrasonic transducers. Among these materials, lead zirconate titanate Pb(Zr[subscript 1‐x]Ti[subscript x])O₃ (PZT) has been primarily investigated due to its excellent piezoelectric properties. However, environmental concerns due to the toxicity of PbO have led to investigations into alternative materials systems....

Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

Creator:: Carlson, Erik
Abstract:: Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

Synthesis of novel ambifunctional atropisomeric 2,2',6,6'-tetrasubstituted biphenyls and investigation of their properties and organocatalytic activity

Creator:: Sephton, Mark Alan
Abstract:: Ambifunctional axially chiral 2,2',6,6'-tetrasubstituted biphenyls containing nucleophilic (or basic) functional groups juxtaposed with hydrogen-bond donors were synthesized and their properties studied. Applications for the prepared biaryls as potential organocatalysts for enantioselective carbon-carbon bond forming reactions were examined. Processes investigated included: aldol, Michael, nitroaldol (Henry), and Baylis-Hillman reactions. The novel amidoamine...
