Collection of problems in colloidal chemistry . Textbook" edited by H. N. Gavrilova and other authors are an indispensable resource for students, graduate students and teachers seeking to better understand the complex aspects of colloidal chemistry. Published in 2009, this work covers a wide range of tasks that will help readers not only to consolidate theoretical knowledge, but also to develop practical skills in solving problems related to colloids and their properties. Colloidal chemistry is a field of science that studies systems consisting of small particles that do not dissolve in a liquid, but remain suspended in it. This topic is becoming increasingly relevant in the modern world, where colloids play an important role in a wide variety of industries: from medicine and pharmaceuticals to the food industry and materials science. The book by Gavrilov and his colleagues offers readers the opportunity to immerse themselves in this fascinating field, providing them with not only theoretical foundations, but also practical tasks that will help develop analytical thinking. The collection of tasks includes a variety of exercises, ranging from simple to more complex, making it suitable for both beginners and more experienced students. Readers will be able to find problems related to basic concepts of colloidal chemistry, such as properties of colloidal systems, mechanisms of stabilization and coagulation, and methods of analysis and research of colloids. Each task is accompanied by detailed comments and recommendations, which allows readers not only to find the right answers, but also to understand how and why they are obtained. This book will be especially useful for students of chemical and biological faculties, as well as for those interested in physical chemistry and materials science. Teachers will find in it an excellent addition to the training courses, and graduate students will be able to use the collection to prepare for exams and defend dissertations . In addition, the book can attract the attention of researchers working in the field of colloidal chemistry, providing them with new ideas for experiments and research. The topics raised in this tutorial cover not only theoretical aspects, but also the practical application of colloidal chemistry in various fields. For example, readers will be able to learn about how colloids are used in the production of cosmetics, medicines and even in food products. This makes the book relevant and useful for professionals working in these fields, as well as for anyone interested in modern scientific achievements. The style of the authors is distinguished by clarity and accessibility, which makes it easy to digest the material . N. N. Gavrilov, as one of the leading experts in the field of colloidal chemistry, has already established himself as an authoritative scientist, and his work is respected in the scientific community. In this collection, he and his colleagues were able to combine their knowledge and experience to create a resource that will be useful not only for students, but also for everyone who seeks to expand their horizons in the field of chemistry. If you are looking for a high-quality tutorial that will help you understand colloidal chemistry, the Colloidal Chemistry Taskbook will be an excellent choice. This book will not only enrich your knowledge, but also inspire further research and discoveries in this fascinating field of science. Do not miss the opportunity to immerse yourself in the world of colloids and discover new horizons in chemistry!
