In-Situ Confocal Scanning Laser Microscopy and Post-Exposure Analysis of a Cu/Fe-based Oxygen Carrier Material in High-Temperature Oxidation and Reduction Environments for Chemical Looping Combustion Applications

Creator:: Nealley, W. H. Harrison
Abstract:: A Cu/Fe-spinel-based oxygen carrier designed at the National Energy Technology Laboratory was studied in order to characterize its physical and chemical behavior with cyclic oxidation and reduction treatments at 800°C for applications in chemical looping combustions. Observations were made on individual particles of the oxygen carrier in-situ using a confocal...

Characterization of Low Temperature Crystallization Growth Parameters of the Growth-dominated Phase Change Materials: Ge1Sb6Te1 and Ga15Sb85 by Optical Microscopy

Creator:: Winseck, Mark M.
Abstract:: Phase change memory materials are a set of chalcogenide or pnictogenide materials systems currently being researched for use in optical and resistive based memory systems due to their large change in optoelectronic properties between the amorphous and the crystalline states. For these materials systems to be considered as a suitable...

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...

Reactivity Testing of Waterglass and the Investigation into an Alternative Binder Enhanced with Cellulose Nanocrystals

Creator:: McAlexander, Melissa
Abstract:: Most of the concrete in the world is produced using hydraulic cement (ordinary portland cement, OPC) and siliceous or alumino-siliceous supplementary cementitious materials (SCM). Due to the shift in focus toward environmental sustainability within the construction industry, alkali-activated cementitious systems (AAC) have gained significant attention to reduce the carbon footprint...

Synthesis, characterization, and analysis of nitroaromatic compounds

Creator:: McIntosh, Melissa Luana
Abstract:: Nitroaromatic compounds have important chemical applications and can be found in nature as pollution sources. Synthetic nitroaromatic compounds have been used in a variety of materials including explosives, pharmaceuticals, dyes, plastics, and pesticides. These compounds can find their way into the environment through normal or improper disposal methods. Poly-aromatic compounds...

Foraging in disturbed areas : a study of sweat bees (Hymenoptera: Halictidae) in Oregon

Creator:: Broussard, Melissa
Abstract:: Bees provide vital ecosystem services for cropping systems as well as natural landscapes. Declines in both both native bee and managed honey bee (Apis mellifera L.) populations has brought attention to the significance of their role as pollinators in managed and native ecosystems. As a result, conservation efforts have been...

Analysis of diagonally cracked conventionally reinforced concrete girders in the service load range

Creator:: Robelo, Melissa J.
Abstract:: Performance evaluation of conventionally reinforced concrete (CRC) bridge superstructure elements with diagonal cracks is of interest to the bridge engineering community. Standardized methods to predict service-level stress magnitudes in cracked bridge girders under combined bending and shear forces are not available. An analysis procedure was developed to determine the response...

Composition, structure, and biomass of cottonwood-dominated gallery forests along a successional gradient, Willamette River, Oregon

Creator:: Fierke, Melissa K.
Abstract:: Recognizing the importance of native black cottonwood-dominated riparian forests is especially important to preserve, protect, and manage for biodiversity in the Willamette River Valley. Species composition, structure, and biomass along a successional gradient from stand initiation to late succession of black cottonwood (Populus balsamfera L. subsp. trichocarpa (T. & G.)...

Exploring Educational Tools to Improve Transboundary Groundwater Management

Creator:: Steritz, Melissa S.
Abstract:: Groundwater tables are dropping quickly in many regions of the world. Central Asia is an arid region where groundwater abstraction rates often exceed recharge rates. The Pretashkent Aquifer is a crucial transboundary groundwater resource for the Republics of Kazakhstan and Uzbekistan. Both countries rely on the aquifer as a primary...

Arribada nesting of olive ridley sea turtles (Lepidochelys olivacea) at La Escobilla, Mexico

Creator:: Ocana, Melissa Ann S.
Abstract:: Olive ridley sea turtles (Lepidochelys olivacea) present an interesting case study of the conservation of wildlife species that aggregate in high densities and have served as resources for human consumption. Ridleys exhibit synchronized mass-nesting behavior, during events called "arribadas," where thousands of females lay eggs together in a small area...
