Growth, Characterization, and Application of Antimony Sulfide Thin Films via a Novel Microreactor Assisted Nanomaterial Deposition for Solid State Batteries

Creator:: Chun, Bryan H.
Abstract:: The continuous development of higher performing battery materials has emerged in parallel with the development of new manufacturing processes. Nanomaterials are one solution to addressing the cycling and performance challenges that limit existing battery cells. However, many of the methods used today for nanomaterial synthesis are high temperature batch methods...

LPBF and Post Processing of H13 Tool Steel

Creator:: Alabdulali, Ali
Abstract:: Laser powder bed fusion (LPBF) is an innovative method where metal powder is fused together to generate complex geometries. LPBF is used as a technology to reduce material waste, and extensive labor that are often linked to conventional subtractive manufacturing. H13 tool steel is one of the widely used materials...

Optimal control of an underactuated bipedal robot

Creator:: Jones, Mikhail S.
Abstract:: Bipedal robots represent a unique class of control problems that combine many of the most difficult elements of nonlinear control. These robots are typically designed to be mobile and as such have limited energy and actuator authority making efficiency a prime concern. Unlike wheeled robots, legged robots must transition between...

Potential Additive-Manufacturing of Ablative Thermal Protection Systems

Creator:: Hazell, Kenya K.
Abstract:: Electrodeposition is a versatile polymer deposition technique to create nano-microscale materials using an electrical field generated from a charged droplet of solution and a grounded collector. Electrospinning or electrospraying can occur during electrodeposition, leading to the creation of nanofibers or bead-like materials depending on the process parameters. Photopolymerization of the...

Predicting Properties of Bio-jet Fuels using Machine Learning and ATR-FTIR Spectroscopy

Creator:: Mayer, Morgan A.
Abstract:: High-potential molecules derived from biomass sources may suitably replace or supplement traditional nonrenewable hydrocarbon fuels to reduce pollution and fuel processing costs. Due to expensive and time-consuming property testing, models that predict key properties from optical data would initially vet potential additives before investment and bench-scale testing. Attenuated Total Reflection...

Determination of cohesive parameters for aerospace adhesives

Creator:: Hortnagl, Josef G.
Abstract:: The use of adhesives in demanding engineering applications is a very common occurrence in the modern world. These adhesives are taking the role of many traditional fasteners, especially in the area of fiber reinforced composites. As the use of these adhesives become more common place, better understanding of their mechanics...

Assessing Mass Diffusion Modeling in Premixed Flames

Creator:: Fillo, Aaron J.
Abstract:: Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...

Identifying the Effects of Combustion Products, Turbulent Fluctuations, and Delivered Energy on Ignition Characteristics of Forced Ignition of Jet-A/air Mixtures

Creator:: Teope, Kaz I.
Abstract:: The operation of gas turbine engines depends on the reliable ignition of fuel/air mixtures. Gas turbine engines are commonly used as commercial and military aviation power plants. However, consistent ignition within gas turbine engines is still a problem, especially for more challenging operating conditions such as emergency operations. This work...

The Structural Characteristics of Robustness in Large-Scale Complex Engineered Systems

Creator:: Walsh, Hannah S.
Abstract:: Modern engineered systems are increasingly integrated into society, decentralized, and interconnected. However, scale and complexity create unique challenges in system design, such as emergent behavior and unintended consequences. This work investigates the structural characteristics of robustness in complex engineered systems by identifying patterns of under-recognized vulnerabilities at various levels of...

Foam-Core Meniscus Coating and Diffusion Bonding for Energy Applications

Creator:: Saranam, Venkata Rajesh
Abstract:: In the second chapter, a foam-core meniscus coating process was developed for retrofitting 100 nm-scale sol-gel anti-reflective coatings onto in-field solar panels through the deposition, evaporation, and curing of wet films.Advantages of this technique include the means to control fluid flow relative to substrate motion and the ability to conform...
