Microscopic Methods for Determining Particle Sizes of Dispersed Materials . Textbook" edited by H. N. Gavrilova is a unique publication that will be useful for both students and specialists in the field of materials science, chemistry and physics. This manual, created by a team of authors, immerses the reader in the world of microscopic research, revealing before him methods that allow not only to measure the size of particles, but also to understand their impact on the properties of materials. In today's world, where technology is advancing at an incredible rate, knowledge of dispersed materials is becoming especially relevant. These materials are widely used in a variety of industries, from pharmaceuticals to the construction industry. Understanding their structure and properties directly depends on the accuracy of measurements, and this is where microscopic methods come to the rescue. The book offers the reader a comprehensive analysis of these methods, ranging from traditional optical microscopes to modern electron and atomic force microscopes. Readers interested in topics related to nanotechnology, materials science and chemistry will find in this manual a lot of useful information. Students, graduate students and young scientists will be able to use it as a reference, and practitioners as a guide to the use of various methods in their work. The book will be interesting not only for those who already work in this field, but also for those who are just starting their way in science. One of the main topics raised in the book is the importance of accurately determining the size of particles to understand their behavior and interaction in different environments. The authors examine in detail how particle size and shape can influence the mechanical, optical, and chemical properties of materials. This knowledge is critical for the development of new materials and technologies, as well as for the optimization of existing processes. The style of presentation in the book is clear and accessible, which makes complex scientific concepts understandable even for those who do not have deep knowledge in the field of microscopy. The authors use many illustrations and diagrams, which allows them to visualize the described methods and facilitate the perception of information. This guide is not only informative, but also enjoyable to read, making it a valuable resource for a wide audience. N. N. Gavrilova, as an editor and one of the authors, has already established herself in the scientific community thanks to her previous works related to materials and their properties. She actively publishes articles in scientific journals and participates in conferences, which testifies to her deep understanding of the topic and the relevance of the issues raised. If you are looking for a high-quality textbook on microscopic methods in the field of materials science, the book "Microscopic methods for determining the size of particles of dispersed materials" will become an indispensable source of knowledge for you. It will not only enrich your knowledge, but also inspire new research and discoveries in the fascinating world of dispersed materials. Do not miss the opportunity to expand your horizons and immerse yourself in the exciting world of science with this unique edition!
