Physical and Theoretical Chemistry

Chemical Transport and Nonequilibrium Processes

Additional sessions will address coupled heat and mass transfer, thermodiffusion, electrokinetic phenomena, and the formation of reaction–diffusion patterns such as Turing structures and travelling waves. Presentations may cover dispersion in porous media, chromatographic and membrane transport, microfluidic mixing at low Reynolds number, and concentration polarization at selective boundaries. Discussion will extend to entropy production, linear and nonlinear response theory, stochastic thermodynamics of small systems, and the energetics of molecular motors and biological pumps. Modelling of reactive boundary layers, electrode polarization, and transport-limited catalysis will also be considered, along with dimensionless analysis for scaling laboratory results to industrial equipment. Experimental strategies for characterizing nonequilibrium systems will be presented, including tracer techniques, laser-induced fluorescence, magnetic resonance velocimetry, and in situ imaging, with applications to reactors, separation units, fuel cells, and living cells.
