Liquid-Solid Transitions with Applications to Self-Assembly.
(2010)
We study the thermodynamic and kinetic pathways by which liquids transform into solids, and their relation to the metastable states that commonly arise in self-assembly applications. As a case study in the formation of ...
Computational Studies of Surfactant Self-Assembly on Nanostructured Surfaces.
(2010)
The study of interactions between different types of molecules on, or near, surfaces and their self-assembly into patterns is an exciting and challenging area of research in chemical engineering. In particular, a self-assembled ...
Mesoscale Modeling and Computer Simulation of Tethered Nanoparticle "Shape-Amphiphile" Assemblies.
(2009)
In this dissertation, we explore the use of polymer-tethered nanoparticles as a means to self-assemble highly ordered arrays of nanoparticles and nanometer-sized domains. We perform Brownian dynamics simulations to study ...
Multifunctional Carbon Nanotube Thin Film Composites by Layer-by-Layer Assembly Technique.
(2009)
Polymeric layer-by-layer (LBL) assembly offers a pathway for multifunctional / multicomponent materials with molecular-scale control of stratified structures. Among the wide variety nanoscale building blocks such as nanowires ...
Compressible Flows for Fluidic Control in Microdevices.
(2010)
Although studies of microscale flow have covered an extensive range of flow phenomena and flow conditions, one area that has received limited attention is bounded gas flows. This dissertation describes the applicability ...
Theoretical and Experimental Investigation of the Impact of Surfaces on DNA Melting Temperature.
(2009)
The design of microarrays rely on studies geared towards sequence-specific recognition between complementary probe and target molecules in bulk solution. However, this proves to be insufficient to understand the duplex ...
Electric and Microfluidic Manipulation of Molecules and Particles in Microfabricated Devices.
(2007)
Microfabrication technology has enabled traditional chemical and biological research to be performed at the micrometer scale, but the control of particles suspended in fluids and the fluids themselves remain a significant ...
Connecting Structure and Dynamics to Rheological Performance of Complex Fluids.
(2010)
This dissertation reports the development of novel experimental techniques to measure and characterize the microstructure of complex fluids and then link this microstructure to macroscale properties such as rheology and ...
The Effect of Interference Techniques on Fischer-Tropsch Product Distributions.
(2010)
Novel reaction engineering designs, also referred to as interference techniques, have been shown to improve the yield of heavier hydrocarbons in Fischer-Tropsch (FT) product distributions. This dissertation explores two ...
Chemometric Methods for the Determination of Volatile Organic Compounds with Microsensor Arrays.
(2008)
This research addresses critical chemometric modeling and data analysis functions needed to guide the design and implementation of novel meso-scale and micro-scale instrumentation that incorporates chromatographic separation ...
