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...

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...

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...

Environmental Sustainability During the Early Design Phase: Understanding the Uncertainty in the Use Phase, Visualization, and Automating Design Repository Curation

Creator:: Tensa, Melissa
Abstract:: The objective of this research is to support DfX considerations in the early phases of design, particularly Design for the Environment. In order to include DfX considerations, especially early in the design process, there needs to be access to knowledge and information that is usually only applicable further downstream in...

Integrating Systemic and Applied Anthropology Approaches to Identify Barriers and Enablers to Accessing Healthcare in the Province of Buenos Aires, Argentina

Creator:: Copple, Ethan L.
Abstract:: Healthcare access exhibits differing levels of complexity, often requiring multi-disciplinary approaches to study its barriers and enablers. Though Argentina has achieved nominal universal healthcare coverage through its public healthcare system, full effective coverage has not been achieved. The public system also has a parallel private care system, adding further complexity...

A heuristic algorithm for operating yard cranes over storage blocks to minimize the handling time in a container yard

Creator:: Denkaew, Weerakit
Abstract:: In container terminals, the efficiency of loading operations in a container yard highly depends on the productivity of yard cranes. In loading operation, yard cranes have to pick-up the containers which are stacked in the yard-bays to satisfy the work schedule requirement of quay crane, the equipment for loading and...

Development of Temperature-Stable Relaxor Dielectrics for High Energy Density Capacitor Applications

Creator:: McCue, Connor
Abstract:: High performance dielectric materials are needed for high power SiC- or GaN-based electronics which combine the best features of high energy density, low dielectric loss and high reliability and for advanced high-speed and high-voltage energy storage where temperature stability plays an important role in material properties. An ideal capacitor for...

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

Characterization of flow boiling in a fractal–like branching microchannel network

Creator:: Edward, Lee M.
Abstract:: Based on experimental investigations the present study evaluates flow instability and void fraction in a fractal-like branching microchannel network with rectangular cross-section. The hydraulic diameter of the channels ranged from 308μm at the inlet to 143μm at the outlet. The flow network used is characterized by set branching ratios for...
