Investigating the Interconversion of Dinitrogen and Ammonia: An Interrogation of Secondary Coordination Sphere Influences on Critical Intermediates
(Georgetown University, 2021)
The near thermoneutral interconversion of dinitrogen (N2) and ammonia (NH3) sustains life and society on Earth. Altogether, the N2 / NH3 interconversion involves a nexus of high energy intermediates connected through ...
Dynamics and Molecular-Level Control of Solid State Transformations in Molecular Hydrates
(Georgetown University, 2021)
Organic solids are pervasive in the fine chemical industry. The diversity of solid state structures continues to expand with chemical and engineering efforts to design, synthesize, and use fit-for-purpose molecular materials. ...
A Story of a Scientist: A Researcher, Mentor, Teacher, Leader, and Advocate
(Georgetown University, 2021)
In efforts to find renewable and sustainable alternatives to gasoline in transportation vehicles, scientists have been studying the design and use of fuel cells. In a fuel cell, a fuel undergoes a reaction that generates ...
Mechanistic Insights into Catalytic Bond Formation and Electrocatalytic Ammonia Oxidation
(Georgetown University, 2021)
Computational chemistry is a useful technique to gain insight into reaction mechanisms when utilized in combination with synthesis and experimental characterization. Organometallic chemistry particularly benefits from a ...
From Pendant Chains to π-Face Blocking Straps: Enhancing the Role of Side-Chains in Controlling Mechanicla and Optical Properties of π-Conjugated Polymers
(Georgetown University, 2021)
This dissertation is a body of research focusing on conjugated polymers and smallmolecules for organic electronics. The projects in this work are aimed at understanding the interplay between structure and function by ...
Synthesis of Europium-Based Magnetic Semiconductor Nanocrystals and Studies of Their Electronic Properties
(Georgetown University, 2021)
The divalent europium monochalcogenides (EuQ, Q = O, S, Se, and Te) are model magnetic semiconductors, exhibiting strong coupled magnetic, optical, and electronic properties. With rising interests in the synthesis of ...
Single-Source Precursors for the Synthesis of Layered Metal Chalcogenide Nanomaterials: LnX2, CuCrX2, and Bi2X3
(Georgetown University, 2021)
Layered materials belong to a class of compounds in which individual, 2-dimensional units are stacked upon each other and held together by weak intermolecular forces. The layered nature of these materials render them ideal ...
Structure-Property Relationships in Photoluminescent Lanthanide, Bismuth, and Lanthanide-Doped Bismuth Organic Hybrid Materials
(Georgetown University, 2021)
Motivated by demands for novel luminescent materials and design strategies, this work focuses on the synthesis, structural characterization, and photoluminescent properties of solid-state lanthanide (Ln), bismuth (Bi), and ...
Development of Plasma-based Ion Sources for Elemental Quantification and Non-targeted Analysis of Chlorinated and Fluorinated Compounds
(Georgetown University, 2021)
The expanding use of organochlorines and organofluorines in pesticides, pharmaceuticals, and industrial applications, along with environmental contamination by these compounds require the development of analytical methods ...
Enhancing Forensic Evidential Value of Fibers via Single-Fiber Detection and Classification of Fluorinated Oil-and-Water-Repellent Fabric Coatings
(Georgetown University, 2021)
Fibers are a common form of forensic evidence, however, they cannot be attributed to a single source because of the prevalence of fibers with common attributes. Accordingly, fibers are assigned to a class based on their ...
