Abstract: 
In non-equilibrium there is an enormous variety of phenomena so we cannot  hope to formulate a unique theory having a generality comparable to  classical thermodynamics. We have to restrict to subclasses of problems. Diffusion is a phenomenon almost ubiquitous and in recent years  considerable progress in its understanding has been obtained. One  difficulty is to define suitable thermodynamic functionals in far from  equilibrium situations. Large fluctuations have offered a way out as large  deviation rates provide genuine thermodynamic functionals whose singularities describe new phase transitions some of which can take place  only out of equilibrium.
