Many countries have enacted renewable energy targets of 32% or more by 2040 to reduce their carbon footprint. However, due to the intermittent nature of renewable energy sources, long-duration energy storage systems are vital for providing a secure electricity supply. To meet this demand, new battery technologies utilizing earth-abundant and low-cost components are necessary. Among them, non-aqueous redox flow batteries represent a transformative energy storage system due to their flexible material selection and wide operating voltage window. A membrane plays a critical role in these next-generation energy storage technologies as it separates the anode and cathode while allowing for facile …

Masters Theses
In 2012, carbon dioxide (CO2) [carbon dioxide] accounted for approximately 82% [percent] of all U.S greenhouse gas emissions.1 These excessive CO2 levels have been attributed to climate changes that have a range of negative effects on human health and welfare.1 In an effort to decrease these emissions, polymeric membranes consisting of silane- and siloxane-functionalized norbornene units have been targeted as a potential solution for the passive separation of CO2 from other non-greenhouse gases. These substituted norbornene-based polymers were synthesized via vinyl-addition polymerization. Through a series of catalyst trials, commercially available palladium and nickel catalysts were compared along …
