In july I mainly focused on studying the Electrochemical Impedance Spectroscopy (EIS). EIS is a method of characterizing electrochemical systems. This technique measures the impedance of a system over a range of frequencies, and therefore the frequency response of the system, including the energy storage and dissipation properties, is revealed. Often, data obtained by EIS is expressed graphically in a Bode plot or a Nyquist plot. EIS is universal and commonly used method used to studying the rate and the mechanisms of electrode processes and to determine the characteristic of interface electrode/electrolyte. I could use this method to study the processes of electrodeposition of metals, electrochemical characteristic of alloy layers and to study of the corrosion processes.

I participate in „Theory and Practice of Elektrochemical Impedance Spectroscopy” summer school in Bath University (19th -22nd July 2011).

On the training I listened the following lectures:

-Network analysis. An introduction to Linear Ciruit Analysis and Circuit Elements”; Dr Frank Marken (University of Bath);
-“Frequency response analysis”; Professor Laurie Peter (University of Bath);
-“Introduction to Electrochemical Instrumentation”; Dr John Harper (Solartron Analytical);
-“Electrical Properties of Materials”; Dr Jason Riley (Imperial College London);
-“Impedance of Electrochemical Systems”; Dr Toby Jenkins (University of Bath);
-“Spectroelectrochemical Impedance”; Dr David Fermin (University of Bristol);
-“Solartron Systems: Extreme Impedance”; Dr John Harper (Solartron Analytical);
-“The uses of equivalent circuits”; Professor Stephen Fletcher (Loughborough University);

and I also attended in the following lab sessions:

• "Seeing those sine waves”
• "Getting to know the equipment”
• „Fitting the software"
• "The impedance properties of a simple redox reaction: the ferri/ferrocyanide couple"
• "Characterisation of a lead-acid battery by EIS"
• Studying corrosion by EIS" (part I)
• Studying corrosion by EIS" (part II) "Practical Impedance Spectroscopy: measurement of polymer film porosity and corrosion"
• "Studying the dye sensitized solar cell (DSC) by Impedance spectroscopy"
• "The impedance Characteristic of Polyaniline
• Studying of Porous Electrodes and Supercapacitors by EIS".
