  • Multicellular monolayer’s self-organization under external stimuli

    Creator:
    Li, Guanyu
    Abstract:
    Cell signaling under external stimulation is a critical mechanism that governs many biological processes such as cell proliferation, cell migration, and cell apoptosis, etc. For multicellular organisms, the ability to synchronize heterogeneous individual cellular responses through intercellular communication is crucial to maintain normal functionality. However, even though the biological pathways...

  • Multi-scale Investigation of Bidirectional Feedback Mechanism Between Breast Cancer Cells and Extracellular Matrix

    Creator:
    Kim, Jihan
    Abstract:
    Cell migration is fundamental for physiological processes such as immune re-sponses, wound healing and development. It is also a critical characteristic of metastatic cancer cells. An extensive amount of studies have focused on 2D sub-strates in order to understand the mechanism of cancer metastasis. However, much less is known about...

  • Mechanics of three-dimensional microenvironments of cells

    Creator:
    Jones, Christopher
    Abstract:
    The structure and mechanics of tissues affect many important cellular functions such as migration, differentiation, and growth. Mechanical interactions between cells and the extracellular matrix (ECM), as well as ECM-mediated mechanical communication between cells, plays a part in coordinating collective cellular dy- namics during critical processes such as morphogenesis, tissue...

  • Photophysics of organic semiconductors at the nanoscale

    Creator:
    Grollman, Rebecca R.
    Abstract:
    Organic semiconductors are used in a wide variety of applications including transistors,solar cells, and light emitting diodes. These materials are solution-processable,low cost, and tunable. Many successful organic optoelectronic materials utilizeblends of several types of molecules (such as donors and acceptors) in order topromote charge generation. As blends are an inherently...

  • 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...

  • 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...

  • Carbon nanotube devices engineered by atomic force microscopy

    Creator:
    Prisbrey, Landon
    Abstract:
    This dissertation explores the engineering of carbon nanotube electronic devices using atomic force microscopy (AFM) based techniques. A possible application for such devices is an electronic interface with individual biological molecules. This single molecule biosensing application is explored both experimentally and with computational modeling. Scanning probe microscopy techniques, such as...

  • Structural Elucidation of Metal-Oxo Systems by X-Ray Scattering Methods

    Creator:
    Kozma, Karoly
    Abstract:
    Metal-oxo clusters are discrete molecular metal-oxides. Most metals form numerous cluster compounds that can be ligated, unligated, charged or neutral, controlling their solubility in water and/or organic solvents. They are important species to study reaction pathways from the monomeric building units to the bulk metal oxides, and have many application...
