Multi-Scale Modeling and Simulation of Polymeric Liquids in Fast Extensional Flows
(2019)
This thesis contains simplified simulations of polymers in the entangled melt/solution state and in the glassy state in fast extensional flows where chains become locally stretched at modest strains. Comparisons to ...
Investigation of In-vivo Integument Mechanics for Device Design at the Bio-mechanical Interface
(2023)
The term "bio-mechanical interface" refers to the point where living organisms interact with mechanical devices. This connection often leads to varying degrees of discomfort due to force interactions and impedance differences ...
Thermomechanical Behavior of Shape Memory Alloy Cables and Tubes.
(2012)
Shape memory alloys (SMAs) are well known for their substantial power density in shape memory mode and their large recoverable strains in superelastic mode. NiTi, the most popular SMA, has been studied extensively in pure ...
Organic Electronic Devices for Sensing and Imaging Applications.
(2009)
While electronic devices based on organic materials have an increasing presen-ce in display, lighting, and photovoltaic applications, sensor applications have been relatively unexplored. Organic semiconductors offer unique ...
Interstitial Diffusion in Li-ion Battery Electrodes and Structural Phase Transitions in Crystalline Solids from First Principles.
(2010)
We perform first-principles investigations of thermally activated phase transitions and diffusion in solids. The atomic scale energy landscapes are evaluated with first-principles total energy calculations for different ...
Laser Processing of Aluminum Alloys: Hypereutectic Al-Si Surface Remelting and Al6061- RAM2 Additive Manufacturing
(2023)
This dissertation undertakes a comprehensive exploration of laser processing of Aluminum alloys. The studies began with laser surface remelting, which is a basic form of laser-matter interaction. In Chapter 3, Aluminum-Silicon ...
Demonstrating High Performing Thermophotovoltaic Systems Using Novel Cell-Side Architectures
(2024)
Thermophotovoltaic (TPV) generation is the conversion of thermal radiation to electrical power through the photovoltaic effect. This is a promising approach for various energy applications such as cogeneration of heat and ...
