The Use of Electrospun Soy Protein Isolate/Polyvinyl Alcohol Nanofibers for Controlled Drug Delivery As Well As Investigation Into Mass Production
(North Dakota State University, 2015)
As the global movement progresses towards environmental awareness, industries are attempting to become less dependent on petroleum based materials. This study investigates the incorporation of Soy Protein Isolate (SPI) ...
Bioprinting of Pancreatic Cancer Cells for Improved Drug Testing
(North Dakota State University, 2019)
Currently, many drugs are preclinically tested on two-dimensional cell cultures. However, this method does not adequately replicate the cellular interactions or diffusion gradient that occur in three-dimensional tissues, ...
Evaluation of Mechanical Properties of Al-Cu Cold Sprayed and Alloy 625 Wire Arc Sprayed Coatings
(North Dakota State University, 2014)
This study examines microstructural-based mechanical properties of Al-Cu composite deposited by cold spraying and wire arc sprayed nickel-based Alloy 625 coating using numerical modeling and experimental techniques. The ...
Assessment of Native Aortic Stenosis Hemodynamics and Clinical Evaluation Methods Using Steady State Computational Fluid Dynamics and Computed Tomography-Derived Geometry
(North Dakota State University, 2012)
Aortic stenosis is the most common valvular heart disease with a prevalence of 2% among individuals over 65 years and 4% over 80, in developed countries. Accurate valve assessment for intervention timing is critical. Using ...
Computational Biomechanics of Blast-Induced Traumatic Brain Injury: Role of Loading Directionality, Head Protection, and Blast Flow Mechanics
(North Dakota State University, 2015)
In this dissertation, blast-induced traumatic brain injury (bTBI) is studied with respect to
the blast wave directionality, mitigation capability of helmet/faceshield, and blast flow
mechanics using finite element (FE) ...
Impact of Recycling on the Mechanical and Thermo-Mechanical Properties of Wood Flour/High Density Polyethylene and Wood Flour/Poly Lactic Acid Composites
(North Dakota State University, 2016)
This research concentrates on the recyclability of two wood plastic composites (WPCs) - wood flour/HDPE and wood flour/PLA composites. Two different filler loadings (30 and 50 wt%) were considered for each polymer composite. ...
Production of Cellulose Nanofibers using Midwest Biomass and their High-Performance Rubber Nanocomposites
(North Dakota State University, 2018)
Cellulose nanofibers (CNFs) are a sustainable and environmentally friendly material which can be used as a highly versatile reinforcing agent in polymer nanocomposites. This thesis presents a novel method to produce CNFs ...
An Experimental Study on a Density Driven Solar Water Heating System Using Supercritical CO2 as Working Fluid
(North Dakota State University, 2013)
For supercritical carbon dioxide, a small change in temperature or pressure can result in large change in density, especially close to its critical point. At this pseudocritical region, density decreases rapidly with ...
Influence of the Biaxiality Ratio on Multiaxial Fatigue of Metallic Materials
(North Dakota State University, 2014)
The ability to model and predict multiaxial fatigue life without being too aggressive or conservative is of great interest to engineers. The purpose of this study was to examine the influence of the biaxiality ratio (σ2/σ1) ...
Theoretical and Computational Studies of the Mechanical Strength and Fracture Toughness of Adhesively Bonded Joints and Polymer Nanoclay Composites
(North Dakota State University, 2019)
Increasing use of adhesively bonded joints (ABJs) and polymer nanoclay composites (PNCs) in modern vehicles and other industrial sectors has deeply shaped the design and manufacturing of advanced materials and structures ...
