Article Citation - WoS: 13Electrochemical and Quantum Chemical Studies on Mitomycin and Adriamycin(Elsevier, 2003) Özalp-Yaman, S; Önal, AM; Türker, LIn-situ spectroelectrochemical redox behaviour of two prominent chemotherapeutic agents, mitomycin and adriamycin were studied at constant potential. AM 1 (UHF) type quantum chemical calculations on the neutral as well as radical anion and cation forms of mitomycin and adriamycin were performed. (C) 2003 Elsevier Science B.V.

The incorporation of GO enhanced membrane hydration, ion-exchange capacity, and hydroxide-ion conductivity, resulting in an ~15% increase in current density at 2.0 V and 80°C (0.551 A/cm2) compared with the pristine membrane (0.480 A/cm−2). The F/GO membranes also showed enhanced hydrogen productionrates and an HHV-based energy efficiency of 76% at 0.5 A/cm2 and 80°C. These results underscore the potential for F/GO mem-branes in scalable AEMEL applications. Mechanical and alkaline stability tests confirmed robustness under harsh conditions.These findings demonstrate that the incorporation of GO provides a simple, scalable, and potentially lower-cost modificationstrategy compared with highly engineered polymer architectures, while also improving overall electrolyzer performance, high-lighting the potential of GO-modified membranes for practical hydrogen production in AEMEL systems.
