Modelling of complex solution phases
A novel approach for modelling complex solution phases (Modified Associate Formalism) with strong interactions between mixing species has been suggested. In contrast to the previous model, the suggested approach, being thermodynamically and mathematically consistent, is free from the entropy paradox. The approach has been successfully applied to modelling gas mixture adsorption on carbon. Parameters of the power series polynomial model have been explicitly related to the Gibbs free energies of the generalised quasichemical reactions. This provides a theoretical justification for such parameters. The other publications are dedicated to accuracy and consistency of thermodynamic modelling.

Competitive thermodynamics
Competitive thermodynamics is introduced to characterise systems evolving due to competition (see CCS ) and found to be quite different from conventional thermodynamics.

This work indicates that interactions of a CP-violating (and
CPT-preserving) quantum system with a thermodynamic environment can produce the
impression of a CPT violation in the system. The paper suggests alternative notations for mixed quantum states -- the random phases -- which allow us to
avoid the use of conventional density matrices.

This work shows that conventional thermodynamics can be extended to antimatter in two mutually exclusive ways (CP- and CPT- invariant). We do not know which one of these extensions is real; resolving this alternative would have profound implications for our understanding of the Universe.

What is "the flow of time" according to Boltzmann and can it be detected directly in physical experiments? CP-violations
may give us such an opportunity. A time-symmetric version of Everett’s manyworlds hypothesis is given in the appendix.

A. Y. Klimenko,
On the effect of decoherence on quantum tunnelling
Springer-Nature Applied Science 3, 710 (2021).
The effects of environmental and intrinsic mechanisms of decoherence on quantum tunnelling are similar but not the same.
This opens opportunities for distinguishing environmental and intrinsic mechanisms of decoherence in experiments and, ultimately,
for experimental investigation of the physical mechanisms responsible for the arrow of time.
