Shaheen Keeps the TEMPO in BEES 2020 Fall Seminar Series
Nora Shaheen, a BEES EFRC graduate student at Case Western Reserve University, presented a talk titled, “Insights into the electrochemical oxidation of TEMPO and 4-hydroxy-TEMPO in ethaline”, as part of the BEES EFRC Fall Seminar Series, organized by the BEES Student Research Organization (SRO). Nora discussed how Deep Eutectic Solvents (DESs) are emerging as promising electrolytes for electrochemical energy storage applications. In research conducted by her, Mahesh Ijjada, Miomir Vukmirovic, and Rohan Akolkar, they investigated the mechanism underlying the electrochemical oxidation of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (4-hydroxy-TEMPO). A significant deviation from the expected anodic charge transfer coefficient was observed and a new underlying mechanism was hypothesized and simulated using numerical techniques giving good agreement with the experimental data.
