WebDiscrete Helmholtz model for ion-exchange membranes Ion exchange membranes (IEM) are widely used in many industrial applications ranging from electrodialysis, to electrolysers and fuel cells.60 The ion-exchange membrane – electrolyte solution interface is polarised and the potential difference is classically referred to as the Donnan potential.

The probability of … See more The Helmholtz free energy function for a pure substance (together with its partial derivatives) can be used to determine all other thermodynamic properties for the substance. See, for example, the equations of state for water, as given by the See more The laws of thermodynamics are only directly applicable to systems in thermal equilibrium. If we wish to describe phenomena like chemical reactions, then the best we can do is to consider suitably chosen initial and final states in which the system is in … See more Computing the free energy is an intractable problem for all but the simplest models in statistical physics. A powerful approximation method is mean-field theory, which is a variational method based on the Bogoliubov inequality. This inequality can be formulated as … See more Hinton and Zemel "derive an objective function for training auto-encoder based on the minimum description length (MDL) principle".

The double layer was compared to parallel plates by Helmholtz. A potential difference is thus created between the metal and solution. Under standard conditions, this potential difference is the standard electrode potential at the metal solution interface. http://nicadd.niu.edu/~piot/phys_630/Lesson2.pdf smithing stone 5 location
