The fundamental discoveries made in materials science domain have substantially increased the mankind's ability to modify matter. The fundamental properties, processing, and advanced applications of micro/nanostructured materials have initiated a rapidly growing interest among the materials science communities. Presently, the advanced and intelligent materials are the most promising trends due to their unique properties. In addition, smart electronic materials have a very high innovation potential for the utilization in numerous practical applications. In this way, the 4 th International Conference on Trends in Material Science and Inventive Materials [ICTMIM 2022] establishes a platform to discuss and collect together the novel research ideas leading to new innovations from a fundamental point of view and real-time applications and in many cases it utilizes the novel functionalities. 4 th ICTMIM 2022 has planned to discuss the challenges in realizing the smart electronic materials with functionally significant properties that are attractive for innovative real-time applications. The conference also welcomes the discussion on new approaches to establish composition-structure-properties and the possibility of using the obtained data for solving the materials science challenges.
