Unique Mechanisms of Ion Storage in Polyaniline Electrodes for Pseudocapacitive Energy Storage Devices Unraveled by EQCM-D Analysis.

ACS Applied Materials and Interfaces, 2022
The optimal performance of organic electrodes for aqueous batteries requires their full compatibility with selected electrolyte solutions. Electrode materials having 1-3-dimensional structures of variable rigidity possess a confined space in their ...

EQCM studies on polypyrrole in aqueous solutions

Journal of Electroanalytical Chemistry, 1997
Abstract Electrochemical quartz crystal microbalance (EQCM) studies revealed that the electrochemical properties of polypyrrole (PPY) in aqueous solutions are greatly dependent on the solution pH. A PPY film immersed in an aqueous KCl solution shows redox processes which involve not only anion transport but also cation transport if the solution pH is

Investigation of FeS Precipitation Kinetics by EQCM

CORROSION 2019, 2019
Abstract The precipitation kinetics of FeS were studied at varied system temperatures using an Electrochemical Quartz Crystal Microbalance (EQCM). Two different substrates were used for FeS precipitation studies: a cathodically polarized iron-coated quartz crystal, and a freely corroding iron-coated quartz crystal.

An Instrument for Simultaneous EQCM Impedance and SECM Measurements

Analytical Chemistry, 1999
A novel combination of an electrochemical quartz crystal microbalance (EQCM) and a scanning electrochemical microscope (SECM) has been built. Unlike conventional EQCMs, the instrument described here allows rapid in situ measurement of the modulus of the quartz crystal's transfer function. Data analysis in the complex plane for the Butterworth-Van Dyke (

Ionic liquid thin layer EQCM explosives sensor

Sensors and Actuators B: Chemical, 2009
Abstract An integrated sensor that combines electrochemical and piezoelectric transduction mechanisms into a single miniaturized platform was developed and validated for the detection of nitro aromatic compounds such as ethyl nitrobenzene (ENB) and dinitrotoluene that are analogues of redox active explosives. An ionic liquid (IL) BMIBF 4 was used as

Analysis of cholinesterase binding to a carnitine-modified EQCM sensor

Biosensors and Bioelectronics, 2007
A sensor for cholinesterases (ChEs) has been developed by binding carnitine via 1,6-diaminohexane to a mixed monolayer of 11-mercaptoundecanoic acid/11-mercapto-1-undecanol on the surface of a gold-coated quartz crystal. Catalytically active and organophosphate-inhibited acetyl- and butyryl-cholinesterases of different origins were tested for their ...
