Investigations into Redox Carriers for Carbon Dioxide Capture and Concentration

Abstract: The development of carbon dioxide capture and concentration technologies is vital to mitigate anthropogenic carbon dioxide emissions. Nearly all of the illustrative mitigation pathways to decarbonization depend upon CO2 capture. Current state-of-the-art technologies for carbon capture are predominantly thermal based. However, the practical applications of this technology have been limited by low overall energetic inefficiency due to Carnot limitations and thermal sorbent degradation.

Thermodynamic Considerations for CO2 Activation and Further Reactivity of CO2 Reduction Products

Abstract:

Growing global energy demands and greenhouse gas emissions require the development of innovative technologies to both sustain the energy needs of the future and eliminate anthropogenic sources of climate change. By designing and deploying systems that capture, concentrate, and convert CO2 to useful feedstocks on large scale using renewable, carbonless energy sources, we may be able to achieve a net neutral carbon economy.

Preparation and Properties of Paramagnetic Mono- and Bimetallic Co Complexes

Abstract: Many important and synthetically challenging chemical reactions are carried out by metalloenzymes, including water oxidation, nitrogen fixation, O2 reduction, and oxidation of C–H bonds including as methane, fatty acids, and pharmaceuticals. Metalloenzymes are able to catalyze these reactions in part due to their ability to access reactive intermediates which is facilitated by the protein host.

Development of Polydisulfide Polymers for RNA Delivery

Abstract: The events of the COVID-19 pandemic have accelerated developments into mRNA therapies and research into novel mRNA delivery vehicles. While lipid-based nanoparticles have gained prominence, polymeric nanoparticle vehicles remain promising biodegradable vectors for new therapeutic RNAs. Within this dissertation two convergent approaches to polydisulfide polymer synthesis are explored.

From Proteins to Protons: Design of Nanoscopic Conductive Polymer Biosensors for Point-of-care Diagnostics

Abstract: Electrically conductive polymers are used in biosensing architectures of many kinds due to their biocompatibility, high electrical conductivity, and ease of polymerization. These factors permit creative techniques to fabricate innovative nanoscale biosensors for point-of-care diagnostic purposes. The focus of this thesis defense will be on the fabrication, sensing properties, and characterization of two different nanoscale, conductive polymer biosensors.
