Chemical Solution Deposition and in-situ Structural Characterization of Pb-free, Bi-based, Piezoelectric Thin Films

Creator:: Fox, Austin J.
Abstract:: This work explores the electric field induced strain mechanisms in environmentally benign Bi0.5Na0.5TiO3 (BNT) based piezoelectric thin films. Although BNT-based materials show promise as replacements for toxic Pb-based piezoelectrics, the displacement mechanisms are not consistent between thin films and bulk materials, and the differences have yet to be well understood....

Structure-property relationships of layered oxypnictides

Creator:: Muir, Sean W.
Abstract:: Investigating the structure-property relationships of solid state materials can help improve many of the materials we use each day in life. It can also lead to the discovery of materials with interesting and unforeseen properties. In this work the structure property relationships of newly discovered layered oxypnictide phases are presented...

Hydrogen production via a sulfur-sulfur thermochemical water-splitting cycle

Creator:: AuYeung, Nicholas J.
Abstract:: Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...

Transient electric birefringence for the characterization of cellulose nanocrystals and tobacco mosaic virus

Creator:: Taylor, Melissa J.
Abstract:: The development of a transient electric birefringence (TEB) apparatus for macroparticle characterization is herein discussed. The experimental difficulties encountered were related largely to poor data resolution. Misalignment and strain birefringence in optical components further complicated results. Improved data digitization methods were developed, and precise mathematical models were derived in order...

The chemistry and device applications of amorphous thin-film interfaces

Creator:: Knutson, Christopher C.
Abstract:: Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...

Tuning Functional Properties of Pyrochlore and Related Oxides via Cation and Anion Substitutions

Creator:: Giampaoli, Gabriella C. S.
Abstract:: Inorganic structures play an important role in materials due to their versatility and diversity. A complete understanding of the structure of a material is vital to enhance the creation of new materials that fill voids in research. The rational design of these compounds is driven by the exploitation of structure-property...

Metal-oxo Clusters as Novel Photolithographic Materials: How Understanding the Chemistry of HafSOx Informs Next-Generation Patterning Systems

Creator:: Amador, Jenn M.
Abstract:: The solution chemistry and kinetic behavior of hafnium peroxy sulfate solutions ("HafSOx") is described in terms of peroxide content and solution speciation. Additionally, thin film behavior, including thermal behavior and solubility, is characterized, and a mechanism of patterning is presented, as well as parameters that should be considered when looking...

Aqueous complexation of citric acid and DTPA with selected trivalent and tetravalent f-elements

Creator:: Brown, M. Alex
Abstract:: Carboxylic acids have played an important role in the field of actinide (An) and lanthanide (Ln) separations and the reprocessing of irradiated nuclear fuel. Recent bench-scale experiments have demonstrated that 3-carboxy-3-hydroxypentanedioic acid (citric acid) is a promising aqueous complexant that can effectively aid in the separation of transition metals from...

Examination of low-lying rovibrational states of D₃[subscript h] oblate top molecules using high resolution FTIR and coherent anti-Stokes Raman spectroscopies

Creator:: Kirkpatrick, Robynne
Abstract:: Interesting rovibrational characteristics of two D_(3h) oblate symmetric top molecules were studied. Hamiltonian models for the fine rovibrational level structure of [1.1.1]propellane (propellane) were obtained for many low-lying modes. Ground state parameters (GSP) that are not exclusively K^(2n) dependent were obtained. Initially, the GSP were used in conjunction with density...
