Electrochemical Quartz Crystal Nanobalance

摘要: The method of piezoelectric microgravimetry (nanogravimetry) using an electrochemical quartz crystal microbalance (EQCM) or nanobalance (EQCN) can be considered as a novel and much more sensitive version electrogravimetry. EQCN technique has become widely used in several areas electrochemistry, electroanalytical chemistry, bioelectrochemistry, etc. [1–10]. Obviously, mass changes occurring during adsorption, sorption, electrosorption, electrodeposition, spontaneous deposition followed, which is very helpful for the elucidation reaction mechanism via identification species accumulated on surface. These investigations include metal alloy deposition, underpotential electroplating, synthesis conducting polymers by electropolymerization, adsorption biologically active materials, analytical determination small ions biomolecules. Of course, opposite processes, i.e., dissolution, electrodissolution, corrosion, also studied. Electrochemical oscillations, formation oxidation chemisorbed molecular fragments play determining role, have been studied, too. majority devoted to ion solvent transport associated with redox transformations electrochemically polymers. Similar studies carried out regarding polynuclear surface layers such hexacyanometalates well inorganic organic microcrystals different compositions.
