Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

Creator:: Teng, Fei
Abstract:: The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

Photoinitiated grafting of PMMA onto cellulose nanocrystals to improve nanocomposite reinforcement-matrix interface

Creator:: Mirashrafi, Suzanne
Abstract:: Cellulose nanocrystals (CNCs) are extremely abundant, biodegradable and light weight nanoparticles that have the potential to contribute in many fields including packaging, construction, solar cells and automotive. With the increasing interest in nanotechnology and nanocomposites, CNCs could provide a renewable, optically transparent and strong alternative to other nano-scale reinforcement phases....

Manufacturing Process Design and Electrically-Assisted Embossing of a Microchannel Solar Receiver

Creator:: McNeff, Patrick S.
Abstract:: Manufacturing process design (MPD) represents a design-oriented approach to manufacturing engineering. In this dissertation, Haynes 230 (H230), a solid solution-strengthened Ni-based superalloy, was chosen to meet the material requirements of a microchannel solar receiver (MSR) needed to increase the efficiency and reduce the cost of solar thermal power generation. An...

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...

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...
