As thermodynamic systems with Lennard-Jones interaction the processes of adsorption in three samples of thermodynamic space are considered. It is established that for adsorption in mesoporous the control parameter is defined as the ratio of the potential energy of the phase distribution surface to the potential energy of the mesoporous walls. The control parameter of the kinetics of biofilm adsorption is the ratio of "life time" to "mortality time level". For the defined three samples of thermodynamic space, the equations of state are theoretically obtained. The comparison of theoretical models with experimental data is given. As a thermodynamic system with Coulomb interaction, smoky plasma with condensed dispersed phase was investigated. The morphology of aluminum oxide particles and their sorption characteristics were experimentally determined. The formula for the calculation of the relative melting point of small crystalline structures is theoretically obtained, depending on the geometric factor and the fractal dimension within the thermodynamics of small systems. The solution of the nonlinear Poisson-Boltzmann equation to determine the distribution of electrostatic potential in the plasma in conjunction with the equation of ionization equilibrium, taking into account the shift of equilibrium in the gas phase.It is established that the key factor in the heterogeneous process of growth of silver nanoparticles is the interphase interactions of the embryos with the reducing agent of the chemical reaction - sodium citrate. The autocatalytic nature of the growth of silver nanoparticles is revealed, with the catalyst of the heterogeneous process being the silver atoms on the surface of the nanoparticles.
