Webinars

This webinar covers the basics of electrochemical impedance spectroscopy (EIS), including theory behind the technique, data processing, Bode/Nyquist plots, data accuracy and validity, and use of the Kramers-Kronig transforms.

This webinar covers applications of electrochemical impedance spectroscopy (EIS), specifically electrochemical interfaces, circuit elements, RC/RQ circuits, capacitors vs. constant phase elements (CPEs), and series vs. embedded models.

This webinar covers applications of electrochemical impedance spectroscopy (EIS), specifically electrochemical interfaces, circuit elements, Warburg models, both infinite and finite, and corrosion models.

This webinar covers electrochemical impedance spectroscopy (EIS) parameters, potentiostatic vs. galvanostatic EIS, how to choose experimental parameters, software control, experimental flow, and real EIS experiments live.

This webinar covers electrochemical impedance spectroscopy (EIS) circuit fitting, tips and tricks in AfterMath Blue software, special features, and general strategies.

Mott-Schottky is an electrochemical impedance spectroscopy (EIS) technique used to study semiconductor properties.  This webinar starts with basics of molecular orbitals, atomic structure, and band theory, followed by principles of semiconductors (band gap, intrinsic vs. extrinsic, n-type and p-type, Fermi level, band bending, and space charge capacitance).  Finally, Mott-Schottky analysis and mathematics are explained.

In Part 4 we will continue talking about cyclic voltammetry and discuss a few more details regarding interpretation of voltammograms and coupled chemical reactions.  The last topic will be on advanced voltammetry techniques such as pulse techniques like differential pulse voltammetry

In Part 3 we take all the concepts of potential, electrode kinetics, and mass transport and we use them to understand cyclic voltammetry.  Topics include chronoamperometry, cyclic voltammetry, understanding voltametric response, and practical aspects of performing voltammetry.

Part 2 covers the concept of electrode kinetics, Butler-Volmer vs Marcus theory, mass transport and diffusion.

Part 1 covers what is voltammetry, electrochemical potential, Nernst equation, electrical double layer, working electrodes, and reference electrodes.

This webinar covers basics of how a potentiostat works, including feedback loops and operational amplifiers, as well as uncompensated resistance, where it comes from and how to correct for it.

This webinar covers rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) electrochemistry, specifically the data analysis of methods such as Levich, Koutecky-Levich, Tafel, and collection efficiency.

This webinar covers rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) electrochemistry, including the theory of kinetics and diffusion as well as methods such as Levich, Koutecky-Levich, Tafel, and collection efficiency determination.  Live RRDE experiments are also shown to collect real data to be analyzed in a separate webinar.
