The book “Heterogeneous equilibria in one- and two-component systems”, written by a team of authors, is an important and relevant publication for anyone interested in physical chemistry, thermodynamics and materials. This work will certainly become a reference book for students, graduate students, and professionals working in the fields of chemistry, physics, and engineering. The book focuses on heterogeneous systems that play a key role in various scientific and practical fields. The authors examine in detail the processes taking place at the boundaries of the phase separation, and investigate how the interaction of different components affects the equilibrium in systems. Readers will be able to learn about how heterogeneous equilibriums are formed and what factors affect them, which allows them to better understand the basic principles of thermodynamics and their application in real-world conditions. This book will be of particular interest to those studying physical chemistry, materials science, and engineering sciences. Students, graduate students and teachers will find useful materials in it to prepare for classes and research. It will also be useful to practicing chemists and engineers working in the development of new materials and technologies, where understanding heterogeneous equilibria is crucial. Topics raised in the book range from basic thermodynamics to complex models describing the behavior of multiphase systems. The authors discuss aspects such as the effect of temperature, pressure and concentration on equilibrium, as well as methods for experimental study of these processes. The book contains many examples and illustrations that help the reader to better understand the material .. The style of the authors is distinguished by clarity and accessibility, which makes complex concepts more understandable. They use both theoretical and practical approaches, which allows readers not only to study the theory, but also to apply the knowledge gained in practice. This makes the book a valuable resource for those who want to deepen their knowledge of heterogeneous systems. The book "Heterogeneous equilibria in single- and two-component systems" may also be of interest to those who are looking for literature on related topics, such as physical chemistry, thermodynamics, chemical engineering, and materials science. Readers interested in works such as "Physical Chemistry" P. Atkins or "Thermodynamics" L. K. Pearson, will find in this book useful additions and extensions to their knowledge. In conclusion, Heterogeneous Equilibriums in Single- and Two-Component Systems is not just a book, but a true guide to the complex and fascinating world of heterogeneous systems. It offers a unique look at the thermodynamic processes that shape our reality. If you are keen to understand how different components in systems interact and want to deepen your knowledge of physical chemistry, this publication will be an indispensable assistant for you. Do not miss the opportunity to discover new horizons of science and technology with the help of this book!
