Electrochemical and chemical loading: How bulk flux and reactions adjust to the impositions of surface fluxes

Wayne M. Saslow

(Texas A+M University)

Abstract: We consider slow, steady surface processes that chemically "load" atoms and ions into a material, where the atoms and ions can react. The material takes up the "load" both by a surface mode involving diffusion and reaction, and by a bulk mode whose properties depend on the "load" and on the chemical reaction. A timely example is the electrochemical oxygenation and pressure-induced oxygenation of high T_c materials. For the uninitiated, we begin by discussing a non-reacting chemical system -- the car battery.
