The Local Structure of Functional Electroceramics

Creator:: Culbertson, Charles M.
Abstract:: This work investigates the relationship between the local structure and physical properties of a set of classical (MgTiO3, CaTiO3, SrTiO3, and BaTiO3) and complex ((1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3[BZT-BCT], Na0.5Bi0.5TiO3 [NBT]) perovskite electroceramics. The materials in this work were synthesized via standard solid state ceramic synthesis, the structure was investigated through a number of...

Development of complex perovskite dielectric ceramics for high temperature capacitor applications

Creator:: Raengthon, Natthaphon
Abstract:: Dielectric ceramics designed for capacitor applications for use in extreme environments, such as high temperatures, high voltages, or high-pressure environments, are in great demand. Existing capacitor technology fails to perform within these extreme conditions or such environments. The development of new dielectric ceramic materials for high temperature capacitor applications is...

Evaluating balance and strength of older women in exercise programs

Creator:: Dinger, Melanie
Abstract:: Falls are a common problem among older adults, including those who are relatively healthy and living independently. Exercise has been recommended as an intervention to reduce falls by slowing and/or reversing age-related declines in balance, strength, and mobility. However, it remains unclear which types or combinations of programs are most...

Structure and piezoelectric properties of lead-free bismuth-based perovskite solid solutions

Creator:: Huang, Chien-Chih
Abstract:: A new group of lead free piezoelectric perovskite solid solutions, (1-x)Bi(B'B")O₃-xABO₃, were obtained via solid-state processing techniques. The solubility of unstable perovskite Bi(B'B")O₃ compounds into stable perovskite compounds was found to be related to the tolerance factor of the ABO₃ perovskite endmembers. The morphotropic phase boundary (MBP) in perovskite solid...

Relaxor characteristic and phase evolution of complex perovskite barium titanate bismuth zinc titanate ceramics

Creator:: Triamnak, Narit
Abstract:: Relaxor characteristic of the solid solution (1-x)BaTiO₃-(x)Bi(Zn₁/₂Ti₁/₂)O₃ (BTBZT) was investigated in this research. X-ray diffraction technique and Raman spectroscopy revealed the crystal structure of BT-BZT at various compositions. For compositions with x ≤ 0.08, the solid solutions exhibited clear tetragonal symmetry and transitioned to pseudo-cubic symmetry as the content of...

Development and validation of a scale to measure vocational educators' attitudes toward the handicapped

Creator:: Clauser, Craig
Abstract:: The problem of this study was to develop and validate an instrument that would measure vocational teacher trainees and practitioners' attitudes toward handicapped learners. The item pool consisted of 90 items which addressed three major dimensions of attitudes toward handicapped vocational students: handicapping conditions, characteristics of these conditions, and the...

Translating the Better Bones and Balance Intervention Program into the community setting: effects of participation on skeletal health, fall risk indicators, and physical activity among older women

Creator:: McNamara, Adrienne J.
Abstract:: Better Bones and Balance (BBB) is a community-based exercise program to improve bone health and reduce fall risk among older adults. Prior research has shown that when the program is delivered by researchers under controlled conditions, participants improved strength and balance, and maintained bone mineral density (BMD) at the hip....

Medicaid Behavioral Health Service Utilization and Satisfaction during the COVID-19 Pandemic: An Urban County Case Study

Creator:: Ferrone, Carly Trakofler
Abstract:: The COVID-19 pandemic in the United States resulted in fluctuating patterns in behavioral health service utilization and a rapid, unprecedented expansion of telehealth service delivery. The Medicaid population may have faced unique challenges in this environment, particularly with telehealth services, given the usability, technology, and reliable connectivity for such services...

Functional materials for advanced energy and electronic devices

Creator:: Flynn, Brendan T.
Abstract:: Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...

Structure-Property Relationships of Disordered Electronic Materials : From Crystalline to Amorphous

Creator:: Surta, Todd Wesley, Jr.
Abstract:: Two perovskite materials (Bi0.5(A)0.5)(Sc0.5Nb0.5)O3, where A = K+ and Na+ were synthesized phase pure for the first time. Their structures were determined by indexing synchrotron X-ray diffraction data and subsequent combined Rietveld refinement on neutron and synchrotron X-ray diffraction data revealing significant disorder on the A-sites of these materials. A...
