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 Tc materials.
For the uninitiated, we begin by discussing a non-reacting chemical system --
the car battery.
