Highly Sensitive EQCM Sensor for Mercury Determination by Coupled Stripping Voltammetry
International Journal of Electrochemical Science, 2015 An electrochemical quartz crystal microbalance (EQCM) can be used as electrochemical stripping sensor for mercury (II) detection. Due to the frequency changes of EQCM electrode were used as analytical signal instead of currents, the influence of ...

Controlling Competitive Radical Pathways: Insights From Aryl Diazonium Electrografting. [PDF]
ChemistryThis work shows that nitrobenzene diazonium electrografting results from competition between aryl and diazenyl radicals, which govern film composition. Using simulations and control strategies, grafting conditions are tuned to favor specific radicals. It enables selective formation of azo‐enriched films and paves the way toward the precise control of ...
