Hi all,

This week at SPAMS we have Sabri Kilic, who will be talking about the 
"Statistical Mechanics of Nernst-Planck Equations". The talk will be 
held at 5pm today in 2-139, and will be followed by pizza in the 
Applied Math Common Room.

Hope to see you then,

Chris, Pak, Kevin,
The SPAMS Organizers.

Title:
Statistical Mechanics of Nernst-Planck Equations

Abstract:
Electrochemical systems are most commonly described by the 
Nernst-Planck equations, which can be derived through an intuitive 
reasoning of fluxes over a control volume. In this talk, we present 
an alternative derivation of Nernst-Planck equations using 
statistical mechanics. As a byproduct, we modify our model in a way 
to account for the finite size effects of the ions and the water 
molecules, which result in the so-called modified Nernst-Planck 
equations. The solutions of this set of equations, unlike standard 
NP, never exceed the physical limit set by the ion size, eliminating 
one of the weaknesses of the NP system.
