This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.
In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.
Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

The evolution of photosynthesis caused the oxygen-rich atmosphere in which we thrive today. Although the reaction centers involved in oxygenic photosynthesis probably evolved from a protein like the reaction centers in modern anoxygenic photosynthesis, modern anoxygenic reaction centers are poorly understood. One such anaerobic reaction center is found in Heliobacterium modesticaldum. Here, the photosynthetic properties of H. modesticaldum are investigated, especially as they pertain to its unique photochemical reaction center. The first part of this dissertation describes the optimization of the previously established protocol for the H. modesticaldum reaction center isolation. Subsequently, electron transfer is characterized by ultrafast spectroscopy; the …
