Investigation of dioxygen activation by copper(II)–iminate/aminate complexes
Papanikolaou, Michael G.; Hadjithoma, Sofia; Chatzikypraiou, Dimitra S.; Papaioannou, Dionysios; Drouza, Chryssoula; Tsipis, Athanassios C.; Miras, Haralampos N.; Keramidas, Anastasios D.; Kabanos, Themistoklis A. (2018)The activation of dioxygen by metal ions is critical in chemical and bio-chemical processes. A scientific challenge is the elucidation of the activation site of dioxygen in some copper metalloproteins, which is either the ...

Oxidovanadium(IV/V) complexes as new redox mediators in dye-sensitized solar cells: A combined experimental and theoretical study
Apostolopoulou, Andigoni; Vlasiou, Manolis; Tziouris, Petros A.; Tsiafoulis, Constantinos G.; Tsipis, Athanassios C.; Rehder, D.; Kabanos, Themistoklis A.; Keramidas, Anastasios D.; Stathatos, Elias (2015)Corrosiveness is one of the main drawbacks of using the iodide/triiodide redox couple in dye-sensitized solar cells (DSSCs). Alternative redox couples including transition metal complexes have been investigated where ...
