Lignin and Cellulose Nanofibers Enhanced Corn-Based Thermoplastic Composites
(North Dakota State University, 2021)The goal of this project is to develop biobased thermoplastics and composites using corn as the main raw material. Corn contains mainly starch, zein, and oil. Thermoplastic starch/zein blends were prepared through internal ... -
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, ... -
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 ... -
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 ... -
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 ... -
Synthesis and Utilization of Si6H12 and Si6X12 (X = Cl, Br) for the Generation of Novel Silicon Materials
(North Dakota State University, 2017)Cyclohexasilane (Si6H12) and its derivatives, Si6X12 (X = Cl, Br), have chemical and physical properties different from linear and branched polysilanes, thus creating interest in their use as starting materials for a variety ... -
Development of Bio-based Wood Adhesive by Using Cellulose Nanofiber Reinforcement and Crosslinking Agent for Improved Bonding Strength
(North Dakota State University, 2017)Engineered woods, plywood, particle board, and oriented strand board, are widely used as a low-cost wood replacement in many applications. Many of the currently used wood adhesives contain chemicals that are harmful to ... -
Mechanical Properties of Multilayers of Carbon Nanotube Polystyrene Nanocomposites
(North Dakota State University, 2017)We have studied the mechanical behavior of multi-layered composite films comprised of single-wall carbon nanotubes and polystyrene polymer, where we focused on three targeted layer thicknesses; 10 nm, 20 nm, and 40 nm. The ... -
The Free and Restricted Diffusion of Silicon Nanocrystal Clusters
(North Dakota State University, 2015)Biological applications for silicon nanocrystals (SiNCs) have recently gained more attention because of silicon’s low toxicity. But, to be able to use SiNCs in applications such as biological sensors, labeling or drug ... -
Electrochemical Impedance Spectroscopy Study of the Ultraviolet Exposure of Ballistic Resistant Polymer Matrix Composites
(North Dakota State University, 2012)This study examined the effect of ultraviolet radiation on ballistic resistant polymer matrix composites. Two composite systems studied included a phenolic matrix with either S2 Glass® or Kevlar® fiber laminates. These ... -
Temperature Dependent Optical Properties of Silicon Quantum Dot/Polymer Nanocomposites
(North Dakota State University, 2012)The photoluminescent properties of silicon quantum dots embedded in a stabilizing polymer matrix are relevant to a number of potential applications of these unique nanomaterials such as drug delivery, temperature sensing, ...
