Development of Hybrid Model for Estimating Liquid Entrainment Fraction and Uncertainty: Integrating Machine Learning and First Principles

Deng, Yushi (2024-05-01) ETD File Embargoed

In two-phase annular flow, a thin liquid film forms around the pipe as gas flows through the pipeline center. Some portion of the liquid is carried into the gas core. The liquid entrainment fraction, which is defined as ...

Differentiation of Mouse Embryonic Stem Cells Using PEG-Fibrinogen Hydrogel Microspheres

Chang, Samuel (2012-05-15)

Cardiac disease is the leading cause of death worldwide, and current treatments are either ineffective at significantly prolonging lifespan or are unavailable to the majority of patients in need due to a lack of supply. ...

Directed Self-Assembly of Tethered Membranes on Nanoparticles

Kelly, Alexander (2018-04-30)

Nanoparticles have demonstrated success in overcoming many barriers of therapeutic delivery. The advantages of these systems include increased drug loading, an ability to package poorly soluble and/or highly toxic drugs, ...

Economic Analysis of Various Reforming Techniques and Fuel Sources for Hydrogen Production

McGlocklin, Kristin (2006-12-15)

Hydrogen is emerging as a future replacement fuel for the traditional fossil fuels that will be capable of satisfying our energy needs. Hydrogen may enable future energy systems to be cleaner, more reliable, and much more ...

Effect of Carbon Supports on Supercritical Hexane Mediated, Fe-Catalyzed Fischer-Tropsch Synthesis

Roe, David (2017-12-01)

The Fischer-Tropsch synthesis (FTS) process consists of surface-catalyzed reactions that collectively convert syngas into hydrocarbons, oxygenates, CO2, water, and heat. In this work, five Fe-based, carbon-supported ...

Effect of Ionic Strength on Cellulose Nanocrystal Dispersion Viscosity and Surface Modification of Thin Film

Hansford, Andre (2018-01-19)

The primary aim of this research was to explore the effect ionic strength on aqueous cellulose nanocrystal (CNC) dispersions with a range of concentrations spanning isotropic, biphasic, and liquid crystalline regimes. The ...

Effect of Process Parameters on Methanol to Olefins Reactions over SAPO Catalysts

Jean, Luckner (2005-08-15)

Acidic catalysts such as silicoaluminophosphate oxides (SAPO) have been known to play an essential role in olefins synthesis reactions. Because of their unique selectivity towards light olefins, these SAPO catalysts offer ...

Effects of Carbon Nanotube Type and Surface Functionalization on the Carbon Nanotube-Unsaturated Polyester Resin Composite Properties

Goswami, Joyanta (2016-12-19)

The goal of this research was to understand the dispersion of carbon nanotubes (CNT) in unsaturated polyester resin (UPR), the relative strength of nanotube-resin interactions, and curing into nanocomposites. These are ...

Electrochemical Characterization and Modelling of Fuel Cells via AC Impedance and Residence Time Distribution

Payne, Robert (2008-12-15)

The performance of commercially available fuel cells was tested under a variety of test conditions and models were formulated to explain the experimental results. Several techniques were applied to single cells and groups ...

Elucidating Interactions within Photoautotroph-Methanotroph Cocultures at Both Systems and Molecular Levels

Badr, Kiumars (2021-07-20)

In the US, the biogas produced from anaerobic digestion (AD) of industrial, municipal, and agricultural waste streams has a great potential as a renewable feedstock. To tap into the immense biogas potential while reducing ...

Emergent Transport in Ion Exchange Membranes

Kim, Jung Min (2021-12-01)

The ion exchange membrane (IEM) is a crucial part of various applications from water purification (i.e. electrodialysis) to energy conversion (i.e. photoelectrochemical CO2 reduction cells (PEC-CRC) and direct urea fuel ...

Encapsulation of Equine Mesenchymal Stem Cells in Injectable PEG-Fibrinogen Microspheres for Local Cell Delivery

Paez-Arias, Mayra (2021-12-06) ETD File Embargoed

Musculoskeletal injuries are a predominant cause of morbidity and lameness in horses. These include fractures, osteoarthritis, chronic wounds, and tendon and ligament injuries. Due to their regenerative potential and ...

Engineered Colorectal Cancer Tissues Employing Patient-derived Cells for Recapitulating the Tumor Microenvironment

Hassani, Iman (2021-04-21) ETD File Embargoed

Colorectal cancer (CRC) remains the third most prevalent cancer and the third-highest cause of cancer-related deaths among both men and women in the United States. The development of pre-clinical CRC models is vital for ...

Engineering Polymer Networks for Enhanced Loading and Extended Release of Therapeutics via Molecular Imprinting

Tieppo Rappo, Arianna (2013-12-10)

Conventional topical ocular therapies such as eye drops and ointments are the current “go to” therapy, and account for over 90% of the market. However, topical drug delivery results in very low drug bioavailability, ranging ...
