Fundamental Investigation Of The Electrocatalytic Activity Of Layered Mixed Metal Oxides For Low Temperature Oxygen Electrocatalysis, Ayad M. Nacy
Wayne State University Dissertations
Li–O2 (Li–air) batteries are among the most promising energy storage technologies due to their high theoretical specific capacity and energy density. Key challenges with this technology include high overpotential losses associated with catalyzing the electrochemical reactions (i.e., oxygen reduction and evolution reactions) at the cathode of the battery. One way to address this challenge is to incorporate an active electrocatalyst, such as first-order Ruddlesden-Popper series of layered oxides. We show that the composition of the A-site in first-order Ruddlesden-Popper series of layered oxides (A2BO4) has a significant effect in the electrochemical activity of Li-O2 cathodes. Among the oxides composed of …

Engineering Of Organic Nanocrystals By Electrocrystallization, Mohamed Kilani
Wayne State University Theses
This work discusses the experimental and theoretical methods used to control the morphology of nanocrystals. The hypothesis of the thermodynamic/kinetic control of the morphology was verified. We applied the electrocrystallization to make K(def)TCP nanocrystals and we tuned the electrochemical parameters to determine their influence on the nanocrystals morphologies. The characterization was mainly performed with AFM and FE-SEM. We presented in this work the possibility to control the morphology of K(def)TCP using the electrochemical parameters. The obtained shapes ranged from nanorods to rhombohedral shape, which is reported for the first time. The observed growth behavior was modeled and simulated with a …

To achieve better property of polymer coatings, different categories of nanoparticles are applied before coating’s curing process. However, one of the adverse effects is the change of final property, which leads the difficulty of product quality control. Using mathematical modeling method can actually improve the cost and time to get a prediction of product quality. Still now, different series of models are developed for various purposes. For example, Monte-Carlo simulation …
