Continuous and rapid synthesis of nanoclusters and nanocrystals using scalable microstructured reactors

Creator:: Jin, Hyung Dae
Abstract:: Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...

Study of graphite-polyurethane composite thin film electrodes for their use in electrochemical antifouling systems

Creator:: Delaney, Matthew A.
Abstract:: Prevention of marine biofouling is vital to the survivability and performance of ships, buoys, and wave energy devices. Coatings that contain metal biocides are currently used to prevent marine biofouling. These coatings have a limited lifetime and are under environmental scrutiny. As a result, it is necessary to research and...

Optimization of cryoprotectant addition and removal procedures for vitrification of adherent mammalian cells

Creator:: Fry Davidson, Allyson
Abstract:: Cryopreservation of adherent cells may be advantageous for cell types that are difficult to preserve in suspension or when it is necessary to preserve characteristics of the adherent cultured cells. Vitrification is a promising procedure for the preservation of adherent cells that prevents ice crystal formation and the resulting dissociation...

Studies of Chitin Nanofiber Production and Photoluminescent Biosilica from Diatoms with and without Germanium

Creator:: LeDuff, Paul A.
Abstract:: There is significant interest in harnessing the biosynthetic capacities of photosynthetic diatom microalgae for the production of unique bioinspired nanomaterials. Specifically, this research focuses on understanding the photoluminescent properties of diatom biosilica and β-chitin nanofiber production in diatoms. Diatoms are single-celled microalgae that possess intricately patterned biosilica shells called, frustules....

Immobilization of Methylosinus trichosporium OB3b in a Biolamina Plate Reactor for the Oxidation of Methane to Methanol

Creator:: Fuchs, Brian K.
Abstract:: Methane is a flammable gas that is the main component of natural gas. It is a highly potent greenhouse gas, and accounts for about 20% of greenhouse gas emissions. Methane is routinely flared in many industrial processes without harnessing any of its energy. The environmental impact and wasted energy potential...

Continuous Flow Microwave-Assisted Synthesis as a Potentially Scalable Nanomanufacturing Approach

Creator:: Albuquerque, Gustavo Henrique T. C. de
Abstract:: The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...

Probing the Biophysical interactions of Anti-Microbial Peptide WLBU2 Using Model Membrane Systems

Creator:: Golbek, Thaddeus W.
Abstract:: WLBU2 is an engineered cationic amphiphilic peptide that targets Gram-positive and Gram-negative bacteria, and envelopes endotoxin while avoiding other cell types. The exact mechanism of how WLBU2 targets, binds, and disrupts bacterial cell membranes is still not completely known. Thus, the overall goal of this investigation is to determine the...

Functional materials for advanced energy and electronic devices

Creator:: Flynn, Brendan T.
Abstract:: Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...

Photoluminescence properties investigation of germanium inserted biosilica generated by bioreactor culture of marine diatom Nitzschia frustulum

Creator:: Qin, Tian
Abstract:: The purpose of this research was to investigate the optoelectronic properties of the Ge doped biosilica, mainly focused on the photoluminescence (PL) properties of diatom frustules of N. frustulum that contain metabolically inserted germanium oxide produced by a two-stage photobioreactor cultivation process. In order to explain the observed PL intensity...

Synthesis and anticoagulant function of heparin containing block copolymers on polystyrene microspheres

Creator:: Fry, Allyson Kaye
Abstract:: Contact of blood with the surfaces of synthetic materials is associated with spontaneous protein adsorption, initiating platelet aggregation, the coagulation cascade, and the eventual development of a stable clot. Current therapy to inhibit implant-induced thrombosis is life-long administration of systemic anticoagulants. An alternative to the systemic administration of anticoagulant drugs...

Investigation of solution-based processes for functional metal oxides : printing, nanostructures, and applications

Creator:: Han, Seung-Yeol
Abstract:: The various solution-based processes, spin coating, inkjet printing, microreactor assisted nanoparticle deposition (MANDTM) and spin-successive ionic layer absorption and reaction (Spin-SILAR) were used to demonstrate thin film electronics and anti-reflective coatings. Several aspects of thin film transistors (TFTs) were tested including a range of temperatures, annealing atmosphere, and deposition methods....

A novel lattice Boltzmann method for treatment of multicomponent convection, diffusion, and reaction phenomena in multiphase systems

Creator:: Parker, James Muirhead
Abstract:: In this work, a multicomponent lattice Boltzmann model is developed for the simulation of multiphase mixing, reactions, and separations processes. This model is unique in that diffusive mass transfer of a component in the model is driven by gradients of chemical potential. This fundamentally correct description of diffusion accurately captures...

Surface-Initiated Click-Ready Bioactive Polymer Coatings: Synthesis and Characterization

Creator:: Yu, Bonan
Abstract:: Protein adsorption on blood contacting medical devices usually causes fouling and failure, and may promote clotting and undesirable immune responses. Hydrophilic polymer coatings in a dense, pendent “brush” conformation can resist protein adsorption on the surface while increasing biocompatibility. Such coatings can also be used to immobilize a variety of...
