Electrochemical insights into alkaline hexacyanoferrate-mediated oxidation of creatinine: Evidence for cyanide release, Iron–Oxo formation, and Iron nanoparticle growth

Electrochemistry Communications
Alkaline hexacyanoferrate (AHCF, ferricyanide in strongly alkaline media, pH ≈ 14) has been widely used since 1962 as an oxidant in catalysis, electroanalysis, and more recently in aqueous redox-flow batteries.

EQCM and Quartz Crystal Impedance Measurements for the Characterization of Thiophene-Based Conducting Polymers

, 1999
EQCM was extensively used to investigate ion-transport phenomena during dopingundoping processes of electronically conducting polymers. Several early studies assumed that the polymer films were rigidly coupled to the quartz crystal so as to relate the ...
