Explorative Investigation into the Thermal and Mechanical Properties of 2D Tubular Braided Composites with an outlook on the future of Green Composites
DownloadSpring 2024
Due to their tailorable mechanical and physical properties, 2D tubular braided composites (TBCs) have many potential applications in fields including aerospace, construction and medicine. Over the past 70 years, many studies have thoroughly investigated several aspects of braided composites...

Fall 2024
Hydrodynamics of the flow around multi-foil systems, representing the tailfin dynamics of collectively swimming fish or fish schooling, were investigated by directly solving the Navier-Stokes equations across a range of flow conditions. The wake and performance of the pitching foils in schooling...

Experimental and theoretical investigation of mechanical responses of bacteria under hypoosmotic pressure
DownloadFall 2024
Bacteria represent a type of ubiquitous pathogen that respond to environmental changes such as osmotic pressure due to their cellular structure. Both Gram-negative and Gram-positive bacteria have distinct structure, including a plasma membrane and cell wall. The primary difference between them...

Fall 2024
Canada has set a goal to reach net-zero electricity. For Alberta, this remains a significant challenge. Although Alberta has achieved considerable greenhouse gas (GHG) reductions by eliminating coal and expanding its renewable fleet, a unique electricity market and the dominance of natural...

Fall 2024
Shape Memory Polymers (SMPs) exhibit responsiveness to stimuli, characterized by the Shape Memory Effect (SME) which enables them to temporarily store a shape and return to their permanent/original form upon the application of a stimulus. However, SMPs face challenges in being applied to...

Evaluating and Enhancing Liquid-Phase Exfoliation of Graphitic Carbon Nitride with Molecular Dynamics and Machine Learning
DownloadFall 2024
Graphitic carbon nitride (g-C3N4) has gained significant attention due to its versatile applications in photocatalysis, energy conversion, and environmental remediation. To harness its full potential, high-quality g-C3N4 nanosheets are essential, which can be achieved through liquid-phase...

Fall 2024
The turbulent structures of Taylor-Couette (T-C) flow of a Polyacrylamide (PAM) solution (200 and 400 ppm) is experimentally investigated and compared with the same flow with water at Re = 1.50 × 104, to understand the effect of nonlinear shear-thinning viscosity on the flow regime, in terms of...

Development of Microstructure-Informed Computational Models for the Design of Cold-Sprayed Additively Manufactured Metal-Ceramic Composite Materials
DownloadFall 2024
This thesis develops microstructure-based finite element (FE) models of cold-sprayed additively manufactured (CSAM) metal-ceramic composites – Al-Al2O3 in this research – to fill a gap in our understanding of the microscale failure progression in the material in correlation with its macroscale...

Fall 2024
This thesis is concerned with the experiments and modelling for the time-dependent behavior of semicrystalline polymers. Relaxation test had long been used to evaluate the performance of materials. In this study, a novel multi-relaxation-recovery test was proposed based on cyclic stages of stress...
