  • Crystallization Rates of AIST and Ge Thin Films by Optical and Electron Microscopy

    Creator:
    Bird, Victoriea L.
    Abstract:
    The amorphous to crystalline phase change is of great interest for the production and operation of phase change memory and germanium electronic devices. Phase change memory relies on the ability to differentiate between differences in optical or electrical properties between the amorphous and crystalline phases of a single material. Amorphous...

  • Determining the dimensional requirements of a reliable compression sealing method for use in microchannel hemodialysers

    Creator:
    Ward, Dustin K.
    Abstract:
    Almost 600,000 people in the United States were treated for End Stage Renal Disease in 2010. A majority of those people received hemodialysis from central medical facilities. It has been reported a better treatment option for these patients would be realized if the patients had more frequent hemodialysis treatments. A...

  • Fabrication of precipitation-hardened aluminum microchannel cooling plates for adsorption-based hydrogen storage systems

    Creator:
    Pawar, Supriya V.
    Abstract:
    The need for clean and renewable fuel such as hydrogen is driven by a growing worldwide population and increasing air pollution from fossil fuels. One of the major barriers for the use of hydrogen in automotive industry is the storage of hydrogen. Physisorption is the most promising storage technique due...

  • Mechanical Design for Robot Locomotion

    Creator:
    Abate, Andrew M.
    Abstract:
    Robotic limbs have been shown to enable mobility in unstructured, real-world terrain; they allow robots to step around cluttered environments, scramble up hills, carry heavy loads, and even perform acrobatics. However, mechanical limbs cannot operate as a means for such dynamic locomotion if they are simply treated as general articulated...

  • Development of an economical high temperature microchannel recuperator for solid oxide fuel cells

    Creator:
    Brannon, Samuel T.
    Abstract:
    To improve the performance of solid oxide fuel cells, a secondary power cycle can be driven by the recuperation of exhaust gas heat. Microchannel recuperators are attractive for waste heat recuperation due to compact form factors which also minimize the mass of the expensive superalloys required. This paper introduces a...

  • On the optimization of performance in fractal-like branching microchannel heat transfer devices

    Creator:
    Heymann, Douglas Benjamin
    Abstract:
    Fractal-like branching microchannel flow networks have been found to improve wall temperature uniformity and decrease both pressure drop and flow power compared to arrays of straight microchannels. The present study seeks to maximize the benefits of fractal-like branching channels by means of a gradient-based optimization algorithm. The algorithm identifies the...

  • Nanoparticle-assisted diffusion brazing of metal microchannel arrays : nanoparticle synthesis, deposition, and characterization

    Creator:
    Eluri, Ravindranadh T.
    Abstract:
    Microchannel process technology (MPT) offers several advantages to the field of nanomanufacturing: 1) improved process control over very short time intervals owing to shorter diffusional distances; and 2) reduced reactor size due to high surface area to volume ratios and enhanced heat and mass transfer. The objective of this thesis...

  • Adhesive microlamination protocol for low-temperature microchannel arrays

    Creator:
    Paulraj, Prawin
    Abstract:
    A new adhesive bonding method is introduced for microlamination architectures, for producing low-temperature microchannel arrays in a wide variety of metals. Sheet metal embossing and chemical etching processes have been used to produce sealing bosses and flow features, resulting in approximately 50% fewer laminae over traditional methods. These lamina designs...

  • Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

    Creator:
    Brannon, Samuel T.
    Abstract:
    High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

    Creator:
    Sobhani, Samaneh
    Abstract:
    Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is a widely recognized powder metallurgy manufacturing process to produce near-net-shape and net-shape components. During general PM-HIP processes the metal powders are filled within a capsule (die), heated and loaded with high pressure simultaneously, and solidified to form the final product. Due to the...
