- Description:
- This dissertation provides an introduction to the diffraction and scattering theory for the Aharonov--Bohm Hamiltonian with one or multiple poles on $\mathbf{R}^2$. It shows the propagation of diffractive singularities of the wave equation with the magnetic Hamiltonians with singular vector potential, which is related to the so-called Aharonov--Bohm effect. Based...

- Description:
- Synthesis opens the pathway to examine a plethora of complex structures. Whether the target is a naturally occurring compound or a proposed molecule never observed before, synthetic routes can be developed to help understand a variety of properties that the molecule can contain. Synthetic efforts have helped elucidate the absolute...

- Description:
- Nanocarriers, structures with at least one dimension on the nanoscale (1-1000 nm), have been engineered for delivery of various cargoes. The shape and flexibility of nanocarriers are important parameters that influence their biological performance. Self-assembling polymeric filamentous nanocarriers, known as filomicelles (FM), are of great interest to nanomedicine due to...

- Very few studies have examined school racial climate in racially diverse school contexts. School racial climate refers to “perceptions of interracial interactions and the socialization around race and culture in a school” (Byrd, 2017, p. 700). The association between interracial peer interactions, psychological well-being, and academic outcomes is well documented,...

- Description:
- This thesis contains two research projects. The first research project examined the coherent nature of electron transfer in two donor-acceptor dyads – one single acceptor control compound and one dual acceptor molecule of interest. Using transient absorption spectroscopy in the ultraviolet/visible/near-infrared and mid-infrared regions, magnetic field effect experiments, and theoretical...

- If I mistakenly hear you ask for directions to the “shore” when instead you asked for directions to the “store,” the miscommunication is probably an innocent mistake. If, on the other hand, a man misunderstands a woman’s refusal of his sexual advances as consent, the mistake seems like it might...

- Description:
- Metal-organic frameworks are crystalline, nanoporous materials formed by metal nodes connected by organic ligands. MOFs represent an exciting approach to materials design where a material with desired properties can be made by choosing the compatible nodes, linkers and topologies independently. MOFs are highly porous and have high surface areas...

- Ovulation is the process by which an ovulatory follicle releases a mature egg and is essential for fertility and maintaining female reproductive cycle. Understanding the mechanisms of ovulation have implications for the development of non-hormonal contraceptives and treatments of anovulatory diseases. We developed a 3D alginate encapsulated in vitro follicle...

- We study the symmetry groups with respect to various equivalence relations defined on subshifts, and more generally, on Cantor systems. Two basic notions of equivalence for dynamical systems are conjugacy and flow equivalence. In this dissertation, we focus on the well-studied automorphism group, which is the group of self-conjugacies, and...
