Hydrodynamic Electrochemistry
Hydrodynamic methods mechanically rotate the working electrode to achieve mass transport by convection. Common applications include Rotating Disk (RDE) and Rotating Ring-Disk (RRDE).
- Comparing Two Competing Pathways by RRDE
- Generator/Collector Type RRDE Experiments
- Theoretical Determination of Collection Efficiency (N)
- Koutecky-Levich Analysis (RDE)
- Levich Study (RDE)
EIS Theory
Electrochemical Impedance Spectroscopy (EIS) is a technique that involves the application and analysis of potential or current sine waves to interrogate chemical processes occurring at an electrode.
- Electrochemcal Impedance Spectroscopy (EIS) Basics
- EIS Basic Background Theory
- EIS Mathematical Theory
- EIS Data Plotting
- EIS Data Accuracy and Validity
Electrochemical Corrosion
Electrochemical Methods are used to study and understand corrosion processes and to interrogate methods of corrosion inhibition, often by Rotating Cylinder (RCE) Electrochemistry.
