  • Plasma-induced modification of films containing polytetrafluoroethylene (PTFE)

    Creator:
    Jones, Hyrum E.
    Abstract:
    Polymer samples of polytetrafluoroethylene (PTFE) and a PTFE-glass weave (RF- 35P) are exposed to low pressure, non-equilibrium glow discharge plasmas for enhanced wettability as measured by static contact angles. Plasma treatments are performed in two parallel plate RF plasma systems, a downstream microwave plasma and a barrel etcher using feed...

  • The influence of surface functional groups on β-lactoglobulin adsorption equilibrium

    Creator:
    Al-Makhlafi, Hamood K.
    Abstract:
    Interactions between proteins and contact surfaces can have important implications in the food industry. Such interactions contribute to the course of fouling of membrane surfaces and they appear to mediate bacterial and spore adhesion to some degree as well. In addition to protein and solution properties, interfacial behavior is strongly...

  • Reactively sputtered films of silicon nitride for diffusion masking

    Creator:
    Delzer, Dennis Richard
    Abstract:
    The experimental procedure for reactively sputtering films of silicon nitride together with the methods for measuring the film thickness have been investigated. Some of the properties of these nitride films were studied. These properties included: infrared spectrum, etching properties, and index of refraction. The adherence of the films was also...

  • 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...

  • Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

    Creator:
    Alemu, Yagenetfere A.
    Abstract:
    The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

  • Two-dimensional temperature model for target materials bombarded by ion beams

    Creator:
    Bostick, Kent C.
    Abstract:
    The ion implantation process is a very precise, controllable, and reproducible method used to enhance material properties of finished components such as ball bearings. Essentially, the target material is bombarded by accelerated ions to form a thin alloyed layer in the substrate. As the ions deposit their kinetic energy in...

  • Aging and performance evaluation of marine antifouling coatings

    Creator:
    Bunn, Malachi D.
    Abstract:
    Marine biofouling is a major problem in many industries. Shipping has been afflicted with reduced vessel speed and hindered maneuverability due to organisms attaching since the dawn of sailing. To date, the primary method developed to prevent fouling is the application of biocide laden coatings with various release mechanisms. Mass...
