Particle Focusing in Microchannels
(2014-02-25)
The ability to control the motion of particles and cells in microchannels has been a center of fascination since the advent of microfluidics. Entire fields have been created in order to accomplish separation, volume reduction ...
Novel Chemistries and Materials for Grid-Scale Energy Storage: Quinones and Halogen Catalysis
(2014-02-25)
In this work I describe various approaches to electrochemical energy storage at the grid-scale. Chapter 1 provides an introduction to energy storage and an overview of the history and development of flow batteries. Chapter ...
Plasmonics for surface-enhanced Raman scattering: from classical to quantum
(2014-06-06)
Metallic nanostructures that employ localized surface plasmon resonances to capture or radiate electromagnetic waves at optical frequencies are termed "plasmonic optical antennas". These structures enhance light-matter ...
Femtosecond laser direct writing of 3D metallic structures and 2D graphite
(2014-06-06)
This thesis explores a novel methodology to fabricate three dimensional (3D) metal-dielectric structures, and two dimensional (2D) graphite layers for emerging metamaterials and graphene applications. The investigations ...
Mechanisms and Implications of Fracture in Cardiovascular Stents
(2014-06-06)
Cardiovascular stents are one of the most widely implanted medical devices, with over 1 million implanted each year in the United States alone. While stent failure modes of restenosis and thrombosis have been widely examined, ...
Design of Mixing Pulses for NMR Spectroscopy by Repeated Rotating Frames
(2014-06-06)
In protein NMR spectroscopy, homonuclear mixing pulses are used to reveal correlations amongst chemically bonded nuclear spins.
Diffusion, Deformation, and Damage in Lithium-Ion Batteries and Microelectronics
(2014-06-06)
This thesis explores mechanical behavior of microelectronic devices and lithium-ion batteries. We first examine electromigration-induced void formation in solder bumps by constructing a theory that couples electromigration ...
Three-dimensional nanofabrication of silver structures in polymer with direct laser writing
(2014-06-06)
This dissertation describes methodology that significantly improves the state of femtosecond laser writing of metals. The developments address two major shortcomings: poor material quality, and limited 3D patterning ...
Femtosecond-laser hyperdoping and texturing of silicon for photovoltaic applications
(2014-06-06)
This dissertation explores strategies for improving photolvoltaic efficiency and reducing cost using femtosecond-laser processing methods including surface texturing and hyperdoping. Our investigations focus on two aspects: ...
Peak Sidelobe Level Distribution Computation for Ad Hoc Arrays using Extreme Value Theory
(2014-02-25)
Extreme Value Theory (EVT) is used to analyze the peak sidelobe level distribution for array element positions with arbitrary probability distributions. Computations are discussed in the context of linear antenna arrays ...
