Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

Creator:: Alemu, Yagenetfere A.
Abstract:: The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

Oxygenate Reactions over PdCu and PdAg Catalysts: Influence of Electronic and Geometric Effects

Creator:: Bathena, Tanmayi
Abstract:: Bimetallic catalysis is a promising way to tune the catalytic properties of heterogeneous catalysts. In particular, bimetallic catalysts are extensively used to enhance the selectivity of monometallic catalysts in a variety of contexts, from oxidation catalysis to oxygenate coupling. In this work, we investigate PdxCuy/SiO2 and PdxAgy/SiO2 catalysts in the...

Deep desulfurization of diesel fuel using a single phase photochemical microreactor

Creator:: Jones, Jacob Aaron
Abstract:: There is an urgent need to lower the concentration of sulfur in diesel fuels. Growing concern over environmental effects caused by burning sulfur-containing diesel has led the world to higher standards in fuel refinement. Because of these lower standards, many techniques have been researched to remove sulfur containing compounds or...

Predicting the Effect of Local Conditions on Metal-oxides: Pt/γ-Al₂O₃ Interface and Degradation of α-Cr₂O₃ Passive Film

Creator:: Oware Sarfo, Kofi
Abstract:: Metal-oxides are very important in industrial applications such as thermal barrier coatings, corrosion protection, and heterogeneous catalysis. The wide variety of applications for metal-oxides are derived from the array of properties of metal-oxides. It is, therefore, important to understand and predict the conditions of synthesis and operation to optimize the...

Solution-based Chalcogenide Thin Film Deposition

Creator:: Pan, Changqing
Abstract:: As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...

Photoluminescence properties investigation of germanium inserted biosilica generated by bioreactor culture of marine diatom Nitzschia frustulum

Creator:: Qin, Tian
Abstract:: The purpose of this research was to investigate the optoelectronic properties of the Ge doped biosilica, mainly focused on the photoluminescence (PL) properties of diatom frustules of N. frustulum that contain metabolically inserted germanium oxide produced by a two-stage photobioreactor cultivation process. In order to explain the observed PL intensity...

Synthesis and evaluation of PEO-coated materials for microchannel-based hemodialysis

Creator:: Heintz, Keely
Abstract:: The marked increase in surface-to-volume ratio associated with microscale devices for hemodialysis leads to problems with hemocompatibility and blood flow distribution that are more challenging to manage than those encountered at the conventional scale. In this work, stable surface modifications with pendant polyethylene oxide (PEO) chains were produced on polycarbonate...

Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

Creator:: Pommerenck, Justin
Abstract:: Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...

Analyzing the Kinetics and Thermodynamics of Surface Reactions using Density Functional Theory

Creator:: Sprowl, Lynza H.
Abstract:: The interactions of chemical species with a solid surface play a role in many everyday applications such as heterogeneous catalysis, corrosion, and degradation reactions. Understanding the reaction kinetics and thermodynamics via rate constants and equilibrium constants, which require knowledge of the adsorbed species’ entropy, is essential for tuning these surface...
