The Development, Characterization and Testing of Mg-rich Primers
(North Dakota State University, 2012)Aluminum alloys are widely used in aircraft industry for their strength and light weight. Those alloys that are hardened by precipitation, especially the Copper-rich of the 2000 series, are prone to corrosion and are ... -
Dynamic 3D In Vitro Bone Metastatic Testbeds for Prostate and Breast Cancer
(North Dakota State University, 2022)Metastatic prostate cancer spreads preferentially to the bone, causing skeletal complications associated with significant morbidity and a poor prognosis, despite current therapeutic approaches. Increasing evidence suggests ... -
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, ... -
Enhanced Bone Tissue Regeneration Enabled with Tissue-Engineered Interlocking Nanoclay Scaffolds and Bone Morphogenic Proteins
(North Dakota State University, 2022)About 6 million bone fractures occur annually in the US; 30% require bone grafting transplants to aid bone healing. Well-established clinical therapy techniques for bone regeneration suffer from limited availability, higher ... -
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 ... -
Experimental Evaluation of Multiscale Behavior of Human Bone
(North Dakota State University, 2014)Bone is the most important structural member of the human body. It has a unique hierarchical structure and its primary constituents, collagen molecules and hydroxyapatite, are arranged in a staggered pattern at nanometer ... -
First Principle Study on Interfacial Energetic Alignment and Charge Transfer in Quantum Dots Functionalized via Metal-Organic Dye
(North Dakota State University, 2016)Quantum dots (QDs) are promising materials for applications in solar energy conversion because of tunable band gap, multi-exciton generation, photon-upconversion, etc. One of the main challenges of increasing solar energy ... -
