Graphene-based Hybrid Electrodes for High-Performance Supercapacitors
… than other capacitors. The interface between the electrodes and electrolytes is crucial in advancing supercapacitor performance, as this solid electrolyte interface (SEI) is where charge storage occurs, and the electrochemical reactions occur. Hence, controlling the chemistry and structure of the …

Nanostructural engineering of vapor-processed organic photovoltaics for efficient solar energy conversion from any Surface
… of OPVs, we integrate vapor-processed carbon-based electrodes and sub-30nm-thin encapsulations in organic photovoltaics, leading to the demonstration of monolithic, robust solar cell arrays as well as the first ever solar cells fabricated directly on paper. Furthermore, we have …

Investigation of oxidation in nonaqueous lithium-air batteries
… in Li-air batteries. In the first part, Vulcan carbon-based electrodes were developed where chemically-synthesized lithium peroxide was included during the electrode preparation process. Variants of these electrodes which further included noble metal catalyst nanoparticles (Au, Pt, and Ru) were …

Integrating photosystem II and electroactive bacteria with three-dimensional electrodes for semi-artificial photosynthesis
… this thesis works with three-dimensional electrodes with different materials and variable morphologies to host photosynthetic enzymes and electroactive bacteria as biocatalysts. Chapter 1 introduces the fundamentals of biocatalysis and artificial photosynthesis, and reviews the progressing …

Electrochemical studies of oxygen reduction for aprotic lithium-oxygen batteries
… 20 2 in Li-02 batteries, using high surface area carbon-based electrodes as model systems. We first report, for the first time, the formation of large ~ 300 nm donut-shaped particles of Li20 2 at high applied potentials during Li-02 discharge, and smaller particles (< 50 nm) at lower potentials. …

BIO-ELECTRORECYCLING OF CARBON DIOXIDE INTO VALUABLE PRODUCTS
Carbon dioxide (CO2) is largely emitted during the combustion of fossil fuels for transportation, electricity generation, and other industrial processes. CO2 is an inorganic compound that naturally exists on Earth, but its concentration has increased exponentially since the industrial revolution, …

Electrochemical determination of gallic acid in food matrices using novel materials.
… pulse voltammetry (DPV) at inert glassy carbon electrode (GCE) or carbon paste electrodes (CPE) have also been used in the determination of GA. However, despite their easy application and fast result generation, their sensitivity and selectivity have been relatively inadequate for the …
