MXene Rheology and Phase Behavior: Exploring the Effects of Sheet Size and Salt Addition
(2023-12-04)
The overall research goal of this dissertation is to understand the effects of sheet size and salt addition on the phase behavior and rheological properties of aqueous MXene dispersions. The charged surfaces of the MXenes, ...
Portfolio Risk-Return Decision Optimization Using AI
(2023-12-04)
Academia and businesses have extensively studied portfolio decision-making under uncertainty and risk. Prediction-based portfolio models usually forecast either the portfolio's future return or risk. On the other hand, ...
A spectroscopic neutral density diagnostic and exploration of the role of metastable states in fusion and astrophysical plasmas
(2023-12-04)
Understanding the transition region between fully ionized and neutrally dominated plasmas is important to the study of the magnetosphere of the earth, the corona/chromosphere transition regions of the sun, and detached ...
Dynamic compressive behavior of additively manufactured 17-4 PH stainless steel
(2023-12-04)
This work focuses on additively manufactured 17-4 PH stainless steel and establishing a correlation between microstructure/printing speed to the dynamic response. Two different methods of additive manufacturing namely Laser ...
Photoresponsive behavior of SPEEK/Cellulose films for oxygen sensing.
(2023-12-04)
Illumination of sulfonated poly(ether etherketone) (SPEEK) and cellulose films by 350nm photons resulted in an efficient redox system. The illuminated films resulted in radicals of SPEEK (SPEEKH•) which in the presence of ...
Essays in Agricultural and Food Policy: Impact of Crop Insurance on Fertilizer Use, Willingness to Pay a Premium on Beef, and Estimating the Demand for Carbonated Sweetened Beverage
(2023-12-04)
In recent years, empirical economic research has witnessed significant advancements. Simple linear regressions have evolved into different applied econometrics toolkits, which cover methods such as difference-in-difference ...
Aerodynamic loads and flow structures on a simultaneously rotating and pitching flat plate
(2023-12-04)
Unsteady flow separation and leading-edge vortices (LEV) profoundly impact the aerodynamics of insect wings, helicopter rotor blades, and similar systems. The dynamics of such systems depend on wing pitch rate and pivot ...
Evaluating the effects of soil tillage on ground nesting bees in the southeastern United States
(2023-12-04)
Pollination by native bees is an economically and ecologically valuable service, necessary in both agricultural and natural landscapes. The majority of bee species nest below ground, an aspect of their biology that raises ...
