  • 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...

  • 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...

  • 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...

  • 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...

  • Femtosecond Stimulated Raman Studies of Excited State Structural Events

    Creator:
    Tang, Longteng
    Abstract:
    Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast vibrational technique which allows rapid collection of Raman spectra with simultaneously high temporal and spectral resolution. With the recent development of FSRS methodology, three FSRS techniques (conventional, tunable, and anti-Stokes) have been implemented in our laboratory to dissect the excited state structural...

  • Functional transition metal oxides : structure-property relationships

    Creator:
    Smith, Andrew E.
    Abstract:
    Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...

  • Preparation and Properties of Porous Carbon Materials

    Creator:
    Xing, Zhenyu
    Abstract:
    Porous carbon is indispensable in modern technology applications. It is used for energy storage, gas separation, water purification, catalyst support, and chromatography. The diversity of its applications stems from its unique properties, including high specific surface area, tunable pore volume, and chemical stability. Specifically, the large surface area provides high...

  • 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...

  • Substitutional Effects on the Electromechanical Properties of Lead-free, Piezoelectric (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT)

    Creator:
    McQuade, Ryan R.
    Abstract:
    This work investigates the effect of cation substitution on the properties of the lead-free, solid solution (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT). Substitution into NBT-BT increases disorder and increases the relaxor ferroelectric properties. These relaxor ferroelectric materials show large piezoelectric strains that can be utilized in actuator applications. Ceramic samples were prepared using standard...

    Wang, Wei
    Abstract:
    A scalable synthesis of the "flat" tridecameric inorganic cluster [Al₁₃(μ₃-OH)₆(μ-OH)₁₈(H₂O)₂₄]¹⁵⁺ has been realized by treating an aqueous aluminum nitrate solution with zinc-metal powder at room temperature. Single crystals and polycrystalline samples are readily obtained in yields exceeding 55% relative to the starting reagent Al(NO₃)₃. Products have been characterized by X-ray...
