  • Analysis of Cellulose Nanocrystal Aerogels

    Creator:
    Buesch, Christian
    Abstract:
    Aerogels are interesting material systems with outstanding properties such as low density, high surface area, and low thermal conductivity. They can be used for a variety of applications, such as solar cells, sensors, or catalysts. Additionally they provide a unique model system to study the properties of small particles. Cellulose...

  • Development and Applications of Oxide Thin Films using Atomic Layer Deposition and Prompt Inorganic Condensation

    Creator:
    Smith, Sean Weston
    Abstract:
    In the first part of this work, thin films of Al₂O₃ deposited via atomic layer deposition (ALD) are demonstrated to improve the thermal stability of cellulose nanocrystal (CNC) aerogels. ALD is a chemical vapor deposition (CVD) like method in which sequential precursor exposures and self-limited surface reactions produce a conformal...

  • Volcanology and petrology of the Rattlesnake Ash-Flow Tuff, eastern Oregon

    Creator:
    Streck, Martin J.
    Abstract:
    The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...

  • Thermal Processing of Injection-Molded Silicon Carbide

    Creator:
    Chinn, Richard E.
    Abstract:
    Silicon carbide is an important and versatile nonoxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding--removal of...
