  • Metal Oxide Cluster Chemistries for Next Generation Nanomanufacturing

    Creator:
    Frederick, Ryan T.
    Abstract:
    Metal oxide clusters are promising inorganic photoresists in next generation nanomanufacturing because of their potential for high-resolution and low line-edge roughness patterning, and exceptional sensitivity to extreme ultraviolet (EUV) radiation. In EUV patterning, absorption of EUV radiation leads to electron emission that serve as a primary species for driving radiation...

  • Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

    Creator:
    Pike, Daniel J.
    Abstract:
    Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...

  • CO2 reduction in aqueous-ionic liquid solution in microscale-based corona reactor, CO₂ reduction in aqueous-ionic liquid solution in microscale-based corona reactor

    Creator:
    Miao, Yu
    Abstract:
    Global warming problem is becoming an increasingly important environmental concern and CO₂ is considered as the major cause of global warming. Among various methods of CO₂ utilization, conversion of CO₂ to value added chemical products is the most attractive. In this study, a microscale-based corona reactor is introduced for reduction...

  • Analyzing the Kinetics and Thermodynamics of Surface Reactions using Density Functional Theory

    Creator:
    Sprowl, Lynza H.
    Abstract:
    The interactions of chemical species with a solid surface play a role in many everyday applications such as heterogeneous catalysis, corrosion, and degradation reactions. Understanding the reaction kinetics and thermodynamics via rate constants and equilibrium constants, which require knowledge of the adsorbed species’ entropy, is essential for tuning these surface...

  • Solution-based nanomaterials and thin films for next generation electronics

    Creator:
    Oleksak, Richard P.
    Abstract:
    Nanomaterials are expected to enable significant advances in several technological fields in coming years. Among them, electronics has emerged as one of the most likely benefactors from the ability to control matter on the nanometer-scale. For many electronic devices synthesized nanomaterials must be integrated into thin film structures. Vapor-based deposition...

  • The effects of engineered coatings and natural organic matter on nanoparticle aggregation

    Creator:
    McDowell, Shannon A.
    Abstract:
    In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

  • Development of traceable metal oxide nanoparticles for examining environmental fate and transport

    Creator:
    Rowbotham, Brian
    Abstract:
    The fate and transport of engineered nanoparticles (ENPs) such as titanium dioxide (TiO₂) are of concern due to their increasing use in consumer products. Although analytical methods for detection and quantification of ENPs in environmental matrices are being developed, these methods are difficult, time consuming, and not easily validated for...

  • Molecular origins of surfactant-mediated stabilization of protein

    Creator:
    Lee, Hyo Jin
    Abstract:
    Nonionic surfactants are commonly used to stabilize proteins during upstream and downstream processing and drug formulation. Surfactants stabilize the proteins through two major mechanisms: (i) their preferential location at nearby interfaces, in this way precluding protein adsorption; and/or (ii) their association with protein into "complexes" that prevent proteins from interacting...

  • Experimental Study of Nucleate Boiling Bubble Dynamics and Heat Transfer Enhancement on Printed Bi-functional Surfaces

    Creator:
    David, Michele
    Abstract:
    Boiling heat transfer is studied for its ability to dissipate high fluxes and achieve heat transfer coefficients two orders of magnitude greater than single-phase heat transfer systems. Heater surface enhancement with increased surface area, varied geometry, wettability contrast and micro/nano-structures can further enhance boiling heat transfer performance through bubble nucleation...

  • Molecular origins of peptide entrapment in polyethylene oxide layers

    Creator:
    Wu, Xiangming
    Abstract:
    A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...
