This book presents the select proceedings of the International Conference on Physics and Chemistry of Materials, ICPCM 2025, covering a wide range of materials of scientific and technological importance. The papers included here provide insights into the latest developments in the field of physics and chemistry of materials, such as condensed matter physics, nanomaterials, polymers, solar energy, semiconductors, and other functional materials. The nanocrystallization of materials has significantly improved their mechanical, physical, and chemical properties, which makes them more suitable for technological applications and the miniaturisation of electronic devices. Solar materials, hydrogen fuel cells, and thermoelectric materials are capable of producing green energy and fulfilling the emergent energy requirements of a technologically dominant world. Development of materials in various fields like medical, textile, defence, agriculture, pharmacy, etc. is taking place very rapidly with increasing functionality. The synthesis and characterisation of advanced materials along with the measurement of various physical and chemical properties as well as their theoretical interpretation has also been discussed here. This book is expected to be useful for academicians, scientists and technologists to design and develop new materials and their advanced applications.
