In the present study, a secondary analysis was conducted to examine SAS growth trajectories from participants of the Work With A Scientist Program (WWASP) – a student-scientist internship which integrated cogen with PBL. Additionally, a thematic analysis was conducted to explore student attitudes toward cogen. The growth …

Study Of Barrier Heights And Magnetic Property Using Locally Scaled And Perdew-Zunger Self-Interaction Methods, Prakash Mishra

Open Access Theses & Dissertations

Kohn-Sham density functional theory is a widely used method to estimate the ground state total energies and densities of interacting correlated electronic structures of atoms, molecules, clusters, solids, and liquids. In theory, exact solutions for these properties can be obtained by solving self-consistent one-electron Schrodinger equations based on density functionals for the energy.The practical application of KS DFT require approximation to the exchange-correlation energy functional. Many density functional approximations (DFAs) have been developed with various degree of sophistication and complexity by the satisfaction of exact constraints. Depending on the complexity, these functionals include electron density, density gradients, density Laplacian, kinetic …

The proposed project required significant research time to depict these subjects, people, places, and stories with greater accuracy. I used what I discovered and applied it in chronological sections depicting the island’s historical narrative. I also attempted to employ a process of historical recall referred to as postmemory by Marianne Hirsch. …

8th Position Bodipy Chemistry, Laura I. Saucedo

Open Access Theses & Dissertations

The projects examined in this dissertation demonstrate how the meso substituents N and S lone pair-BODIPY core interaction influence the chemistry and properties of BODIPY fluorophores. Three objectives were completed experimentally and computationally. In the first project the meso amide substituent delocalizes the nitrogen lone pair into the carbonyl, preventing a hemicyanine resonance that causes blue emission in 8-amino-BODIPYs. The second and third projects substituting aniline or phenylthiol derivatives onto the 8th position, respectively. The aniline and phenylthio lone pair interaction with the BODIPY core can be modulated by electron-donating (ED) or –withdrawing (EW) moieties placed para on the aryl …
