CHAPTER 11: Critical Behaviour: Pure Fluids and Mixtures

Experimental findings on critical behaviour for fluids and fluid mixtures over the past few years have been summarized. This includes the analysis of the complete scaling formulation of asymmetric criticality for the coexistence curves of liquid-gas phase transitions and also for liquid-liquid phase separation in binary mixtures. For these phase transitions, we also reviewed results for ionic solutions as well as the historically elusive check of the thermodynamic consistency between the density and the heat capacity.
