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....

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...

Thin-Film Dielectric Structure of Spin-Coated ZrO2 from Aqueous Inorganic Solution

Creator:: Moreno Luna, Hidekel A.
Abstract:: An inorganic aqueous precursor for the deposition of ZrO2 thin films via spincoating was developed. Hydrolysis and condensation chemistries of ZrOCl₂·8H₂O were used as the principal reactions to guide the synthesis. Refractive index, n, for a film annealed at 300 °C at 550 nm was measured to be n=1.97 by...

Synthesis and Solution Behavior of Tetravalent Metal Clusters with Ammonium Counterions

Creator:: Brown, Jessica C.
Abstract:: Global interest in reducing carbon emissions by use of alternative energy sources makes nuclear energy production and the impacts of the nuclear energy cycle relevant. Studying the aqueous speciation of tetravalent metals commonly used for nuclear energy (uranium, thorium, plutonium) can inform us of general metal properties and their behavior...

Modeling Arctic melt ponds using a resolved ice model with GCM forcing

Creator:: Collins, Lee E.
Abstract:: The albedo of Arctic sea ice depends greatly on the formation of melt ponds. These ponds form in depressions on the ice as surface snow melts during the summer months, and their location is determined mainly by the initial snow topography. Using a high resolution sea ice model forced with...

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...

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...

Detection techniques for biomolecules using semi-conductor nanocrystals and magnetic beads as labels

Creator:: Chatterjee, Esha
Abstract:: Continued interest in the development of miniaturized and portable analytical platforms necessitates the exploration of sensitive methods for the detection of trace analytes. Nanomaterials, on account of their unique physical and chemical properties, are not only able to overcome many limitations of traditional detection reagents but also enable the exploration...
