Abstract

Abstract The 2023 4th International Conference on Material Chemistry and Composite Materials (MCCM 2023) took place during December 22nd to 24th, 2023 in Sanya, China. MCCM exists as an annual international academic conference which tries to meet the needs for various kinds of material chemistry and composite materials. Bearing the principle of “bringing together global wisdom in scientific innovation to promote high-quality development”, MCCM 2023 encouraged the exchange of information on research frontiers in different fields related to material chemistry and composite materials, connected the most advanced academic resources at home and abroad, and turned research results into industrial solutions. It also promoted the development of related disciplines, expanded the international scientific and academic exchange channels, enhanced scientific innovation on a global scale, and contributed to academic cooperation between China and the international community. The Conference was attended by about 100 participants and hosted 6 keynote speeches, many oral and poster presentations, as well as Questions & Answer part. The topics of the 4th MCCM cover various research fields where material chemistry and composite materials are applied, such as Surface Chemistry, New Energy Materials, Nanotechnology and Materials, Physical and Structural Properties of Materials, Multiferroic Materials and Composites, etc. According to all the attendees, the scientific program was excellent with high level of presentations and the scientific environment was fruitful, thus all of them had a great and creative time. In the keynote speech part, Professor Liguang Wang (Zhejiang University, China) shared his research on Understanding the Degradation Mechanisms in High-Energy Density Cathodes via Synchrotron X-Ray Techniques. To advance the development of the next generation of high-energy-density cathode materials, his research endeavors have systematically unraveled the intricacies of performance degradation mechanisms inherent in layered structure cathodes. This exploration leveraged a sophisticated combination of advanced synchrotron X-ray-based characterization techniques across multiple scales. His investigation has been transformative, shedding light on the intrinsic correlation between stress-strain dynamics and mechanical degradation within layered cathode materials. With rounds of dramatic researches sharing and ideas exchanging, the Conference was made filled with academic atmosphere. We would like to thank Beihang University, China for its support. We would also like to acknowledge the members of the Organizing Committee and Technical Program Committee for their preparation and suggestion on the Conference. Our gratitude also goes to the members of Journal of Physics: Conference Series for their support in publishing this paper volume.
