A Study Of Solvent Effects On The Ground And Excited States Of Endohedral Tri-Scandium Nitride C80 Fullerene Coupled With Zinc Phthalocyanine And Metal-Free Phthalocyanine Using Dft-Pcm Method, Timilsina Prasad Timlsina

Open Access Theses & Dissertations

The photovoltaic active materials composed of endohedral metafullerene and phthalocyanine derivatives are known as excellent electron donor-acceptor pairs. The tri-metallic nitride endohedral C80 fullerene exhibits high absorption coefficients in the visible region of the spectrum and has similar electron-accepting abilities as that of C60 fullerene, which can allow for higher efficiencies in OPV devices. In this study, we examine the effect of solvent on the charge transfer excitation energies of Sc3N@C80-ZnPc and Sc3N@C80-H2Pc donor-acceptor molecular complexes. Three different solvents with different polarity - water, toluene, and acetone are used. The solvent is modeled as a polarizable continuum as implemented in …

Beyond The Paradise Tax: Assessing The Potential For Rental Vehicle Electrification In Kaua'i County, Hawai'i, Derek K. Ichien

Cal Poly Humboldt theses and projects

Rental car fleets have high potential to contribute to electric vehicle (EV) adoption within the Hawaiian Islands as part of the state’s efforts to fully decarbonize its ground transportation by 2045. Of the four main islands, Kauaʻi County’s small and simple road network, high penetration of renewable energy, and low speed limits make it an ideal candidate for a pilot EV rental program. This research seeks to accomplish three primary goals: a) quantify the relative economic and environmental benefits of rental electric vehicles over internal combustion rentals, b) identify crucial locations for additional charging infrastructure, and c) provide policy recommendations …

Strategies To Improve The Electrochemical Of Performance Transition Metal Compounds As Anode Materials For Li-Ion Batteries, Noemi Dominguez

Open Access Theses & Dissertations

Nowadays, our society depends on fossil fuels as the main energy source. However, depletion, price fluctuations, and other concerns, such as global warming, have led to an exhaustive research for renewable energy resources. Here is where electrochemical energy systems play a critical role since they can provide power when renewable energy is not available. Among these electrochemical energy storage systems Li-ion batteries (LIBs) have shown higher volumetric, gravimetric, and power density capacities over other battery systems.

However, commercial LIBs are still relying on graphite base materials for the anode. However, graphite possesses a low specific capacity. Recently, transition metal compounds …

The Rhetoric Of Low Carbon Energy Technology Scientists And Engineers, Nicolas Cesar Hernandez

Open Access Theses & Dissertations

Scholars in the burgeoning field of Energy Communication have successfully contributed to communication studies and environmental communication practice. However, energy communication scholars have largely focused on energy of media coverage, corporate communication and decision making in the context crisis. While rich and informative, this tendency has left quotidian aspects of energy communication rather understudied. As such, this Thesis contributes to the understanding of the internal, non-untechnical rhetoric of low carbon energy technology (LCET) scientists and engineers (herein LCET professionals). Textual analysis was used to examine LCET professionals' internal rhetoric at professional trade conferences and through long form, semi-structured interviews. Wind …
