Combining QCM-I and OWLS Measurements to Understand Polymer Multilayer Deposition Processes using OWLS and Quartz Crystal Microbalance with Impedance (QCM-I).
Physical Electrochemistry Techniques
The Applications and Technical Notes below cover, broadly, "electrochemistry" from what a potentiostat is to advanced physical electrochemistry techniques. Click on a link below to download the PDF version of the Application or Technical Note.
QCM-I is a powerful technique for measuring the adsorption or binding of polymers, proteins, nano-particles and other molecules to a surface. Multi-parametric data is obtained in real time, detailing changes of the hydrated mass and rigidity of layers coupled to the sensor surface.
The electrostatically driven adsorption of polymer and nano-particle multilayers is a well-established method for the physical and chemical transformation of surfaces to produce highly tailored and often “smart”, environmentally sensitive interfaces.
Supercapacitors using an EQCM: Supercapacitors have high charge/discharge rates, long cycle life, operate over a large temperature range and have a low cost-per-cycle. (EQCM) is a Quartz Crystal Microbalance that has been interfaced to a potentiostat such that one of the crystal faces is used as a working electrode.
This Application Note deals specifically with bacterial biofilms that convert chemicals to electrical current on electrodes. Because of this function, we refer to them as electrochemically active biofilms (EABs).
Intensity modulated photocurrent spectroscopy (IMPS) and intensity modulated photovoltage spectroscopy (IMVS) can offer valuable information about dye solar cells (DSCs).
This application note discusses the spectroscopic experiments in Gamry’s Framework and explains their setup parameters.
