Substrate Binding And Reduction Mechanism Of Molybdenum Nitrogenase, Zhiyong Yang
Substrate Binding And Reduction Mechanism Of Molybdenum Nitrogenase, Zhiyong Yang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As a key constituent of proteins, nucleic acids, and other biomolecules, nitrogen is essential to all living organisms including human beings. Dinitrogen represents the largest pool of nitrogen, about 79% of the Earth’s atmosphere, yet it is unusable by most living organisms due to its inertness. There are two ways to fix this inert dinitrogen to usable ammonia. One is the industrial Haber-Bosch process, which needs to be conducted at high temperature and pressure. This process uses a lot of the non-renewable fossil fuel as the energy source. The other major pathway is the biological nitrogen fixation carried out by …
Electrochemical Reduction Of Aqueous Uranium, Jonathan M. Scaggs
Electrochemical Reduction Of Aqueous Uranium, Jonathan M. Scaggs
Boise State University Theses and Dissertations
The electrochemical reduction of uranium in acidic aqueous environments with the express purpose of generating U(III) consistently is critically evaluated. Generating U(III) in an aqueous environment is difficult and extremely unstable and has historically been difficult to achieve and isolate for further investigation. The electrochemical cell, electrodes, supporting electrolytes, and pH’s are all reviewed and evaluated for the purpose of optimizing the systemic requirements to electrochemically generate U(III). Several new types of electrochemical cells to include two new spectroelectrochemical for UV-Vis and FT-Raman investigation were designed and tested for the purpose of analyzed the redox species of aqueous uranium generated …
