Destabilization and Aggregation Kinetics of Asphaltenes.
(2014)
Asphaltenes are the heaviest fraction of crude oil and can precipitate due to changes in temperature, pressure or composition. It was previously shown that the precipitation and aggregation of asphaltenes is a kinetic ...
Energy Conversion from Gradients across Bio-Inspired Membranes
(2017)
Membranes are fundamentally important barriers that enable the processes of life by slowing the dissipation of gradients and transducing usable energy from entropic driving forces. This dissertation presents three ...
Isolation and Characterization of Circulating Biomarkers to Predict Patient Outcomes in Late-Stage Non-Small Cell Lung Cancer
(2021)
This work hypothesizes that the molecular characterization of extracellular vesicles (EVs) and circulating tumor cells (CTCs), biomarkers found in peripheral blood draws, can be used to monitor, and predict, treatment ...
Reaction Kinetics, Catalyst Development, and Reaction Networks for Hydrothermal Hydrodeoxygenation.
(2014)
This dissertation examines issues related to producing a hydrocarbon biocrude from wet algal biomass. It first reports on the hydrothermal liquefaction (HTL), a high-temperature (>250 °C) and high-pressure (>40 bar) aqueous ...
Designing Heterogeneous-Based Cascade Catalytic Systems for Carbon Dioxide Hydrogenation.
(2016)
The search for sustainable and economical chemical processes is a key priority for the chemical industry. Cascade catalysis presents a promising technology to meet this need by combining multiple catalysts to drive a ...
Stochastic Modeling of the Formation of Aromatics in Combustion
(2021)
Understanding the formation of polycyclic aromatic compounds (PACs) in combustion not only bridges the knowledge gap between the small gas-phase species and incipient soot particles, but may also help address the global ...
Experimental Assessment of Constraint Release Physics in Entangled Polymers and Its Implication for Rheological Modeling
(2019)
Innovations in the predictive theory, particularly tube models such as the Hierarchical 3.0 model (Wang et al. J. Rheol., 54(2): 223-260, 2010), Branch-on-Branch (BoB) model (Das et al. J. Rheol., 50(2), 207-234, 2006), ...
Experimental and Theoretical Studies of DNA-Macroion Interactions.
(2015)
The thesis uses experiments and simulations to examine the interactions of DNA molecules with proteins and protein-like nanoparticles, with applications to protein search and targeting of DNA sequences, and to DNA complexation ...
Multiscale Modeling of Partially Crystalline Materials
(2023)
Simulation and modeling methods covering multiple time and length scales are here applied to study crystals and materials with partial crystallinity. The first system investigated is the aqueous emulsion of cationic ...
Advancing Empirical Models for the Hydrothermal Liquefaction of Microalgae
(2018)
Hydrothermal liquefaction (HTL) is a sustainable-energy technology used to convert microalgae into an energy-dense biofuel precursor known as biocrude oil. This dissertation illuminates myriad effects of HTL process inputs ...
