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...

Identifying customer requirements and designing for modularity in developing specialized, low production volume products

Creator:: van Tamelen, Peter G.
Abstract:: Field biologists are in need of more specialized and technical equipment than they are able to produce on their own in order to collect data more efficiently or gather data that is not currently available. This presents a challenge for design engineers because these products are typically highly specialized and...

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...

Probabilistic Wind Power Forecasting for Hybrid Systems

Creator:: Irmas, Cameron
Abstract:: Wind power forecasting provides valuable insights for demand response, energy market operation, and plant control optimization. Probabilistic approaches—which capture uncertainty in these complex systems by representing predictions as probability distributions—represent a growing area of research in wind energy science. However, their applications for wind-based hybrid systems, particularly those focused on...

Determination of Mass Flow Rate through Plain Mesh Wick and Nano- Structured Mesh Wick for the Design of Thermal Compressor Systems

Creator:: Uwaoma, Ifeanyi A.
Abstract:: Wicking action refers to the movement of a liquid through a porous or a structured surface via capillary action. This phenomenon is affected by surface geometry, such as the wick thickness and pore size of the wick, as well as fluid properties, such as viscosity and surface tension of the...

Reliable Integrated Planning: Applications in Hub Network Design and Airline Ground Crew Task Assignment

Creator:: Barahimi, Pouya
Abstract:: In general, making optimal decisions is a never ending challenge that decision makers face. A comprehensive model that integrates decisions at all three levels of decision making (i.e., strategic, tactical, and operational) can help the decision maker to find solutions that best serve the organization's performance. However, as organizations expand...

Characterization and theoretical analysis of the effect of geometry on electrical characteristics of flexible thin film transistors

Creator:: Chattopadhyay, Shirsopratim
Abstract:: Flexible Electronics is a fast developing technology that is set to revamp and revolutionize conventional electronics through the development of devices that are easily conformable to surfaces of any arbitrary geometry. Such devices would have vast applications in areas where the rigidity of traditional silicon based electronics is undesirable, such...

The impacts of ionization chemistry on hydrocarbon detonation

Creator:: Zaiger, Matthew F.
Abstract:: As carbon emissions are negatively impacting ecosystems across the globe, researchers are in a race against time to provide cleaner and more eÿcient power. Detonation engines can help meet the increasing demands for cleaner and more eÿcient power generation by providing an alternative means to use oxy-fuel combustion for carbon...

Discovery, Processing and Characterization of New Copper and Hafnium-based Metallic Glass Alloys

Creator:: Saini, Jaskaran S.
Abstract:: Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....

Fully Soft 3D Printed Electroactive Fluidic Valve in Soft Hydraulic Robots

Creator:: Zatopa, Alexander
Abstract:: Soft robots are designed to utilize their compliance and contortionistic abilities to both interact safely with their environment and move through it in ways a rigid robot cannot. To more completely achieve this, the robot should be made of as many soft components as possible. Here we present a completely...
