Analysis Of The Cyclostratigraphy At The Devonian-Carboniferous Boundary In South-Central Oklahoma, Ryan Michael Todd Ellis

LSU Master's Theses
An outcrop in La Serre, France, was officially ratified by the ICS in 1989, and the IUGS in 1990, as the location of the Global Boundary Stratotype Section and Point (GSSP) for the Famennian–Tournaisian, and subsequently the Devonian–Carboniferous (D–C) boundary. GSSPs, like this one, are official outcrops that provide physical representations of geologic time boundaries, essentially geological standards that define geologic time, providing a vital framework to model a variety of interpretations of geological phenomena from paleoclimate to paleontological. It has been acknowledged that the GSSP in La Serre, France is in need of revision due to fossil reworking and …

Renewable energy is a major concern due to increased world energy consumption. In particular, solar energy is a type of renewable energy source that uses devices known as solar cells to convert sunlight to electricity. Specifically, devices referred to as dye-sensitized solar cells (DSSCs) employ dyes to absorb solar energy. Dyes derived from ruthenium complexes have been typically used in DSSCs. Unfortunately, several disadvantages are associated with current ruthenium complex photosensitizers, which can be attributed to limited supply and expense of metals, as well as reduced absorption in the near-infrared region of the electromagnetic spectrum. Accordingly, this dissertation is a …
