New materials are the foundation of high-tech innovations. In order to promote the integration and improvement of the research and industrialization of materials science and engineering among the universities and research institutes in the Greater Bay Area,  Southern University  of Science and Technology (SUSTech) and City University of Hong Kong (CityU) jointly organize the first Greater Bay Materials Research Union Conference. It is hoped that, through the Conference, both Universities can incorporate the attributes and expertise of the two MSE departments to foster research collaboration, knowledge and technology exchange and joint training of talents, which will lay a solid foundation for the development of advanced materials technology in the Greater Bay Area.
