Spring 2016
Hybrids formed by biological entities and human-made nano-structures have been intensively studied in recent years due to their very interesting properties and applications. DNA-carbon nanotube (CNT) hybrid is one such material and the motivation of this PhD study. The interaction of DNA building...

Characterizing the Performance of a Single-layer Fabric System through a Heat and Mass Transfer Model
DownloadSpring 2010
A mathematical model is developed to study the coupled heat and moisture transfer through a fabric system that consists of a single layer of fabric and an air gap. Properties of air and moisture are sensitive to temperature and hence are assumed to be functions of local temperature. Therefore the...

Fracture Modeling in Elastomeric Materials: Relating the Macroscopic Response to Microscopic Processes
DownloadFall 2018
Inelastic material behavior is known to be able to enhance the fracture toughness of elastomers. However, how to optimally exploit this toughening mechanism is still being investigated. In this thesis a series of continuum models are developed to describe such inelastic behaviors, with the goal...

Spring 2018
Shape memory polymers (SMPs) can be used in many critical applications, including biomedical and aerospace fields, due to their ability to recover their original/permanent shape from a deformed/temporary shape upon application of a stimulus. SMPs are subjected to bending in a large number of...

Charged Entities Interacting with Electronically Responsive Structures with Implications for the Modeling of Interactions between Carbon Nanotubes and DNA
DownloadFall 2011
Understanding interactions between charged entities with electronically responsive structures embedded in an electrolytic environment is important because of the diverse range of practical applications. This study was motivated by the technique where single stranded DNA was used to separate...

Spring 2019
Inspired by nature, structured interfaces have been shown to enhance adhesion by trapping crack propagation along the interface. To propagate the trapped crack, more energy input is required externally and therefore the effective fracture toughness is increased. In many applications, directional...

Local surface force density and total surface force induced by a single point charge embedded in a three-layered homogeneous dielectric system with infinite planar interfaces are calculated using the Maxwell Stress Tensor formulation. The tensor is expressed in terms of the electric field which...

Spring 2023
Bio-based composites made from bio-renewable and biodegradable constituents have been proposed as alternatives to petroleum-based composites for a variety of applications. However, studies have shown that in many cases, these bio-based composites are hydrophilic, and their viscoelasticity can be...

Molecular Dynamics Study of Clay-Polymer Interactions in the Treatment of Mature Fine Tailings
DownloadFall 2021
In this dissertation, all-atom molecular dynamics (MD) simulations were performed to study the mechanisms of clay-polymer interactions and the effects of solution chemistry in the treatment of mature fine tailings (MFT). The fine solids in MFT were mainly clay particles such as montmorillonite...

Manufacturing and characterization of blended PVDF/PVDF-TrFE polymers: a study towards future sensor applications
DownloadSpring 2022
Poly (vinylidene fluoride) (PVDF) and its copolymers received increasing attention due to their electroactive properties and lower processing cost in comparison to the conventional piezoelectric ceramic materials, which are widely used in electronics, energy harvesting, biochemistry, and sensor...
