Session I:X-ray absorption spectroscopy in electrochemical research
David Ramaker, George Washington University, Washington DC, USA
Understanding Electrocatalytic Pathways using In Operando XAS: Theory and Practice.
The talk will layout the foundation of this spectroscopy and bring it to life with examples of adsorbate binding sites and particle morphology on Pt based electrocatalysts.
Sanjeev Mukerjee, Northeastern University, Boston MA, USA Understanding Electrocatalytic Pathways in Complex Organic and Inorganic Composites in Aqueous and Non Aqueous Environments'
The talk will cover the applications to study the inner and outer-sphere charge transfer processes and Li-air batteries.
Session II: Modelling and simulation of complex electrochemical systems: challenges and strategies
Oleksiy Klymenko,Ecole Normale Superieure, Paris, France
This tutorial lecture aims to give an overview of contemporary approaches to model complex electrochemical reactions under a variety of conditions including micro- and nano-electrodes. It will be demonstrated how the size and shape of the electrode (which determine the peculiarities of mass transport in the system for ultramicroelectrodes), the nature and rate of reactions, etc., affect the corresponding mathematical models.
Session III: The pH concept in the 21st century
Robert de Levie, Georgetown University, Washington DC, USA
We owe the concept and name-giving of pH to Friedenthal (1904) and Sørensen (1909) respectively. Since that time, ionic concentrations are no longer determined by conductometry, Lewis introduced the concept of activity, and Debye & Hückel gave its quantitative expression in sufficiently dilute solutions. Over time, these developments have led to a quite different concept of pH, which has not had the scrutiny it deserves. This lecture will explore
(1) What is required for a practically useful definition of pH?
(2) Is the current IUPAC recommendation compatible with thermodynamic data?
(3) Are there practical downsides to following the current IUPAC recommendations?
(4) Are there ways to reconcile the problems implied in the above questions?
