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...

Applications of Holographic Optical Tweezers: Multiplexed Fluorescence Spectroscopy and the Micromechanics of Type-I Collagen

Creator:: Cibula, Matthew A.
Abstract:: The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

Bioelectronic Systems for Neurosensing Enabled by Graphene

Creator:: Fengel, Carly V.
Abstract:: Taking long-term electrical measurements of a large number of neurons simultaneously is required for many modern neuroscience experiments. However, such experiments are currently limited by the shortcomings of traditional neurosensing technology. For example, there is a significant mechanical mismatch between rigid silicon probes and soft biological tissues. This mismatch can...

Analysis of the mechanism of sulfoxide-lithium exchange and the reactive intermediate in stereospecific reagent-controlled homologation (StReCH)

Creator:: Hoyt, Amanda
Abstract:: The stereospecific reagent-controlled homologation (StReCH) of boronic esters with enantioenriched carbenoid species generated in situ by the addition of organolithium initiators to stereodefined α-chloroalkyl aryl sulfoxides was previously reported. The reaction of an organolithium with an α-chloroalkyl aryl sulfoxide ostensibly generates an α-chloroalkyllithium via sulfoxide-lithium exchange; however, the true nature...

Investigation of bipolar resistive switching in zinc-tin-oxide for resistive random access memory

Creator:: Murali, Santosh
Abstract:: Resistive random access memory (RRAM) is a non-volatile memory technology based on resistive switching in a dielectric or semiconductor sandwiched between two different metals. Also known as memristors, these devices are potential candidates for a next-generation replacement for flash memory. In this thesis, bipolar resistive switching is reported for the...

Evaluation of amorphous oxide semiconductors for thin film transistors (TFTs) and resistive random access memory (RRAM) applications

Creator:: Rajachidambaram, Jaana Saranya
Abstract:: Thin-film transistors (TFTs) are primarily used as a switching element in liquid crystal displays. Currently, amorphous silicon is the dominant TFT technology for displays, but higher performance TFTs will become necessary to enable ultra-definition resolution high-frequency large-area displays. Amorphous zinc tin oxide (ZTO) TFTs were fabricated by RF magnetron sputter...

Conformational Consequences: Calcium Regulates the Association Between Dysferlin C2A & PI(4,5)P2

Creator:: Otto, Shauna C.
Abstract:: Dysferlin is a ∼230 kDa terminally anchored membrane protein that is ubiquitously expressed, but is particularly enriched in skeletal and cardiac muscle tissue. Mutations covering the length of the protein have been linked to muscle wasting diseases including limb-girdle muscular dystrophy and Myoshi myopathy. Dysferlin has been shown to play...

Synthesis and Analysis of Heterostructural Semiconductor Alloy Sn1-xCaxCh (Ch=S, Se) and Nitrides Zn1-xWxN and Zn1-x(W1-yMoy)xN

Creator:: Matthews, Bethany E.
Abstract:: This work explores the synthesis and characterization of the metastable alloys Sn1-xCaxCh (Ch= S, Se) and nitride compounds Zn-W-Mo-N, which have recently been predicted by theorists. Single phase thin films of Sn1-xCaxS are prepared by pulsed laser deposition and radio-frequency magnetron sputtering and of Sn1-xCaxSe are prepared by pulsed laser...

Fabrication and geometrical characterization of metal and metal-dielectric composite periodic nanostructures

Creator:: Bhowmik, Siddhartha
Abstract:: Periodic metal and metal-dielectric composite nanostructures have been of interest from the field of plasmonics and metamaterial fabrication. In order to exploit the behavior of these unique materials in the visible region of the optical spectrum, these structures need to be significantly shorter than the wavelength of response, and hence...

The optical properties of multi-scale plasmonic structures and their applications in optical characterization and imaging

Creator:: Kuhta, Nicholas Anthony
Abstract:: The optical response of metallic structures is dominated by the dynamics of their free electron plasma. Plasmonics, the area of optics specializing in the electromagnetic behavior of heterogeneous structures with metallic inclusions, is undergoing rapid development, fueled in part by recent progress in experimental fabrication techniques and novel theoretical approaches....
