  • Investigation of low temperature solution-based deposition process for flexible electronics

    Creator:
    Chang, Yu-Jen
    Abstract:
    The critical contribution of this dissertation is to provide a better understanding of the fundamental Chemical Bath Deposition (CBD) growth kinetic and mechanism for the well known II-VI semiconductor CdS using the newly developed continuous flow microreactor. This continuous flow microreactor provides the temporal resolution to control the homogeneous reaction...

  • Conversion of glucose to hydrogen gas by supercritical water in a microchannel reactor

    Creator:
    Goodwin, Aaron K.
    Abstract:
    Glucose was gasified in supercritical water within a microchannel reactor at 650°C – 750°C, and 250 bar to yield H2 rich gas with a low concentration of CO. The feed glucose concentration was 0.1 M. Two microchannel reactor configurations were tested at fluid residence times ranging from 0.5 sec to...

  • Fabrication and characterization of ferrimagnetic film for RF/microwave crosstalk suppression

    Creator:
    Su, Yu-Wei
    Abstract:
    The primary goal of this thesis is to fabricate a magnetic film between the coplanar transmitted stripline for crosstalk suppression. Crosstalk is caused from undesired inductive and capacitive coupling of signals between two conductors. The effective crosstalk suppression results from the inductive coupling of circuit elements through the lossy properties...

  • Catalytic chemical vapor deposition synthesis of carbon nanotubes from methane on SiO supported Fe and Fe−Ni catalysts

    Creator:
    Nakagawa, Ayako
    Abstract:
    Influences of operating conditions on the production of carbon nanotubes (CNTs) were studied using Fe and Fe-Ni bimetallic catalysts supported on silicon monoxide (SiO). The catalysts were prepared in three steps: (1) impregnation of SiO powders with ferric nitride or combinations of ferric and nickel nitrides, (2) oxidation of nitrides...

  • Selective self-assembly of biogenic silica assisted by layer-by-layer deposition and inkjet printing

    Creator:
    Wang, Wei
    Abstract:
    Nature is an inspirational source of silica structures that possess unique optical properties. A few classes of organisms fabricate metal oxides with nanoscale features by a bottom-up self assembly process. In particular, diatoms are a prolific class of single-celled algae that possess silica shells or “frustules” with intricate submicron scale...

  • Biological insertion of nanostructured germanium and titanium oxides into diatom biosilica

    Creator:
    Jeffryes, Clayton S.
    Abstract:
    There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake soluble metal oxides from cell culture medium, and incorporate them into the micro- and nano-structure of their amorphous silica cell walls, called...

  • Physiological response of Nitrosomonas europaea to oxytetracycline, chromium, and silver

    Creator:
    Schaerer, Morgan A.
    Abstract:
    Nitrosomonas europaea carries out the first step in the biological nitrogen removal process in wastewater treatment by oxidizing ammonia to nitrite. It has been shown to be sensitive to a wide range of contaminants. The antibiotic oxytetracycline and the heavy metals chromium and silver have been found in wastewater influent....

  • Fabrication and characterization of nanostructured surfaces for enhanced heat transfer

    Creator:
    Choi, Changho
    Abstract:
    This objective of this study is to investigate the capability of nanostructured surfaces on dissipating heat flux by performing pool boiling and convective flow boiling. The generation of ultra-high heat flux from high performance electric devices has motivated a number of investigations related to advanced heat transfer especially in two-phase...

  • Functional polymers and proteins at interfaces

    Creator:
    Schilke, Karl F.
    Abstract:
    Functional polymers and proteins at interfaces and surfaces are of fundamental importance for biomaterials, biocatalysis and microreactor applications. Candida antarctica lipase B immobilized on poly-DL-tryptophan tethers showed 30x higher specific activity in aqueous and non-aqueous media than the same enzyme adsorbed or covalently bound directly to the surface. An excess...

  • 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...
