  • Cancer Cell Detection with Mask R-CNN

    Creator:
    Wong, Ryan
    Abstract:
    Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...

  • Synthesis and study of transparent p- and n-type semiconductors and luminescent materials

    Creator:
    Park, Cheol-Hee
    Abstract:
    New transparent p- and n-type semiconductors and luminescent materials have been prepared and characterized. Synthesis, structures, optical and electrical properties of new chalcogenide fluoride p-type transparent semiconductors MCuQF (M=Ba, Sr; Q=S, Se, Te) are described. Band-gap tuning and improvement in conductivity through p-type doping are demonstrated in the family. The...

  • Synthesis and study of oxides and chalcogenides : thin films and crystals

    Creator:
    Park, Sangmoon
    Abstract:
    Several types of solid-state inorganic materials are prepared and characterized. By using the SILAR (Successive Ionic Layer Adsorption and Reaction) deposition method in conjunction with hydrothermal dehydration both low-temperature deposition and crystallization of oxide thin films are achieved. Various aspects of new transparent p-type materials are studied by examining both...

  • Broad Histogram Algorithm Comparison for the Square Well Fluid

    Creator:
    Simpson, Tanner T.
    Abstract:
    Thermodynamic properties of systems are often investigated computationally. Traditionally, thermal physics simulations are limited by their very small energy ranges and slow convergence. Broad histogram algorithms are a class of Monte Carlo algorithms that can explore an entire energy (and temperature) range in one thermal physics simulation: potentially saving months...

  • Synthesis and function of bioactive, block copolymer surfactant constructs as relevant to the preparation of anticoagulant and antibacterial medical implant surfaces.

    Creator:
    Joshi, Pranav R.
    Abstract:
    Nisin, an antibacterial peptide proven to be an effective inhibitor of Gram-positive bacteria, was incorporated into novel block copolymer constructs and tested for retained antibacterial activity. Covalent coupling was achieved by chemical modification of the N-terminal isoleucine to introduce a thiol group. Thiolated nisin derivatives were then linked to poly[ethylene...

  • On the Properties and Characteristics of Solution Processed Hafnium Based Thin-Films from Aqueous Precursors

    Creator:
    Decker, Shawn R.
    Abstract:
    Aqueous hydroxo Hf nanoclusters enable studies to identify and codify steps in the deposition of Hf-based oxide thin films from solution precursors. HfOCl2 reacts with combinations of H2O2(aq), acids, and TMAH to produce polymetal species at high pH and low pH. X-ray scattering and spectroscopic methods reveal the nature of...

  • Optical, electronic, and thermodynamic properties of layered mixed anion compounds

    Creator:
    Vielma, Jason Michael
    Abstract:
    Mixed anion compounds that form ZrCuSiAs-type crystal structures exhibit remarkable properties such as superconductivity at low temperatures, hole conduction with optical transparency in the visible region, and exciton absorption at room temperature. In this thesis, properties of a selected group of materials out of the very large set of mixed...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • Experimental verification of a mismatch-shaping DAC

    Creator:
    Hudson, William Forrest, 1971-
    Abstract:
    Delta-sigma data converters have gained popularity in both analog-to-digital and digital-to-analog converters (ADCs and DACs) due to their simplicity, high linearity and immunity to many analog circuit imperfections. These data converters include features such as oversampling, noise-shaping, and (historically) single-bit quantization. Single-bit converters are preferred for their inherent linearity. This...

  • Substitution Effects on the Structure and Electronic Behavior of Ternary Precious Metal Oxides

    Creator:
    Flynn, Joshua
    Abstract:
    Due to the high cost of precursor materials, complex oxides of 4d and 5d transition metals are under-studied compared to their 3d counterparts. Recent studies have shown that oxides containing heavier transition metals can exhibit exotic electronic states due to presence of strong spin-orbit coupling. The goal of this dissertation...
