Bending and Force Recovery in Polymer Films and Microgel Formation
(North Dakota State University, 2018)To determine correlation between geometry and material three different model films: polymethylsiloxane (PDMS), polystyrene (PS), and polycarbonate (PC), were singly bent and doubly bent (forming D-cones). Bends were chosen ... -
Silicon Nanocrystals: Optical Properties and Self Assembly
(North Dakota State University, 2018)Silicon nanocrystal’s (SiNCs) size dependent optical properties and nontoxic nature portend potential applications across a broad range of industries. With any of these applications, a thorough understanding of SiNC ... -
An Electron Energy-Loss Spectroscopic Investigation of Molecular Interactions at Hydroxyapatite-Collagen Interfaces in Healthy and Diseased (Osteogenesis Imperfecta) Human Bone and Biomineralized Tissue-Engineered Bone
(North Dakota State University, 2018)At its primary level (nm scale) bone is a nanocomposite consisting of a mineral (hydroxyapatite) phase which gives bone its strength and an organic (type I collagen) phase giving bone its fracture toughness. Hydroxyapatite, ... -
Lattice Gases with Molecular Dynamics Collision Operator
(North Dakota State University, 2018)The purpose of this dissertation is to provide a direct microscopic underpinning for lattice Boltzmann (and lattice gas) methods. Lattice gases are idealized discrete models that conserve mass and momentum. These conservation ... -
Evaluating Mechanisms of Metastasis of Prostate Cancer to Bone Using 3D Bone-Mimetic Tissue Engineered Scaffolds
(North Dakota State University, 2018)The complex nature of cancer metastasis necessitates the development of a cancer model based on specific metastatic stages. In this dissertation, we report a polymer-nanoclay based in vitro tumor model which recapitulates ... -
Flexible Nanocomposite Thin Films for Electronic Devices
(North Dakota State University, 2019)Electronic technology is moving towards flexible, durable, and smaller devices with multifunctional capability. To accelerate this movement, creating materials with outstanding properties is critical. Nanocomposites based ... -
Non-Thermal Plasma Synthesis of Luminescent Silicon Nanocrystals from Cylclohexasilane
(North Dakota State University, 2019)In this report we establish cyclohexasilane (CHS) as a reliable precursor for non-thermal plasma synthesis of high quality photoluminescent silicon nanocrystals (SiNCs). We demonstrate that this synthesis approach can ... -
Single-Wall Carbon Nanotube Films Dip-Coating by Colloidal Nanocrystals Bilayer Films
(North Dakota State University, 2019)A wrinkling approach was used to study the mechanics of hybrid nanotube/nanocrystal coatings adhering to soft polymer (PDMS) substrates. We focused on three thicknesses: 10 nm, 30 nm, and 40 nm. The approach we used is the ... -
The Effects of Doping on the Lithium Ionic Conductivity of LLZO Solid-State Electrolyte
(North Dakota State University, 2020)Lithium-ion batteries (LIBs) employing solid-state electrolytes are considerably safer and might potentially generate a higher energy density compared. The goal of this thesis is to investigate the synthesis and stability ... -
Tissue-Engineered Nanoclay-Based Bone-Mimetic 3D In Vitro Testbed for Studying Breast Cancer Metastasis to Bone
(North Dakota State University, 2020)Breast cancer shows a high affinity towards the bone, causing bone-related complications leading to poor clinical prognosis. Approximately 80% of breast cancer patients die within five years after primary cancer has ... -
Lead Halide Perovskite Nanocrystals: Photophysical and Photochemical Dynamics
(North Dakota State University, 2021)Lead halide perovskites nanocrystals (LHP NCs) are a recent novel material of ‘high-defect tolerance’ that has been synthesized which have provided a new platform for opto-electronic devices, such as photovoltaics and ... -
Manipulation and Isolation of Biomolecules Using Dielectrophoretic and Hydrodynamic Methods
(North Dakota State University, 2021)Novel particle manipulation techniques are developed to separate, isolate, and control a wide range biomolecules from DNA to cells in complex solution such as whole blood. First, we show that integrating an insulating tip ... -
Investigating the Reduction of Fogging Behavior of Natural Fiber-Filled Polymers
(North Dakota State University, 2021)Synthetic fibers such as glass and carbon are used as reinforcement in polymer composites due to their high strength and modulus. However, synthetic fibers are non-biodegradable and contribute to high costs. In literature, ... -
Adhesion With Slender Structures: Tape Loops, Crumples, and Origami
(North Dakota State University, 2021)The desire for improved adhesive systems led us to examine three geometries: tape loops, crumples, and origami shapes. The tape loop is mechanically interesting because it is stable in more than one configuration. For ... -
