Fluid Dynamics of Material Micro-Deposition: Capillary-Based Droplet Deposition and Aerosol-Based Direct-Write
(North Dakota State University, 2012)
With rapid development of the direct-write technology, in addition to requirement of non-destructive printing, there is a need for non-expensive, robust, and simplified techniques of micro/nano fabrication. This dissertation ...
Characterization of Regenerated Silk Material for Biomimetic Spinning and Film Casting
(North Dakota State University, 2018)
Natural silks produced by spiders and silkworms exhibit tailorable mechanical performance yet to be achieved synthetically. This phenomenon is derived from a biological system that has been evolutionarily optimized. In ...
Nanomechanical Characterization of Tobacco Mosaic Virus Superlattice with Novel Atomic Force Microscopy Methods
(North Dakota State University, 2013)
Tobacco mosaic virus (TMV) has been widely studied due to its excellent properties. In order to utilize TMV superlattice, this thesis initiates the study on its mechanical properties. The elastic modulus of TMV superlattice ...
Dried Distillers Grains With Solubles as a Multifunctional Filler in Wood Particleboards
(North Dakota State University, 2015)
Dried Distillers Grains with Solubles (DDGS) has been investigated for its use as a functional filler in wood particleboards bonded with Melamine Urea Formaldehyde. Both the concentration of the DDGS filler – 5, 10, and ...
Experimental Evaluation of a NACA 0021 Airfoil Employing Shape-Memory Alloy for Active Flow Control
(North Dakota State University, 2018)
Current aircraft use actuators to alter the wing geometry and generate the ideal flight characteristics which is known to be a method of active flow control. By replacing the heavy electric and hydraulic actuators currently ...
Characterization of Mechanical Properties in Hybridized Flax and Carbon Fiber Composites
(North Dakota State University, 2013)
Natural fiber composites have been found to exhibit suitable mechanical properties for general applications. However, when high strength applications are required, natural fibers are typically not considered as a practical ...
Development of Biobased Sandwich Structures for Mass Transit Application
(North Dakota State University, 2012)
Efforts to increase the biobased content in sandwich composites are being investigated to reduce the dependence on synthetically produced or mined, energy-intensive materials for numerous composite applications. Vegetable ...
Characterization, Long-Term Behavior Evaluation and Thermo-Mechanical Properties of Untreated and Treated Flax Fiber-Reinforced Composites
(North Dakota State University, 2017)
In recent years there has been a resurgence of interest in the usage of natural fiber reinforced composites in more advanced structural applications. Consequently, the need for improving their mechanical properties as well ...
The Physico-Chemical Investigation of Interfacial Properties in Natural Fiber/Vinyl Ester Biocomposites
(North Dakota State University, 2012)
Bast fibers are one of most widely used types of cellulosic natural fibers. Flax fibers, a specific type of bast fiber, have historically been used as reinforcements in composites because they offer competitive advantages, ...
Experimental Characterization of Aerosol Flows Through Micro-Capillaries
(North Dakota State University, 2012)
Understanding the forces which dictate fluid particle interaction is of high interest in the field of aerosol jet Direct Write (DW). Several methods utilizing shadowgraphy and Mie scattering were used to visualize particle ...
