Symposium Scope:
This session focuses on recent advances in rare earth and critical materials, which play a vital role in modern and emerging high-technology applications. Topics cover material synthesis, processing, property tailoring, and structural and functional characterization, as well as pratical applications in areas such as clean energy, advanced electronics, optoelectronics, luminescent and magnetic materials, sensors, medical technologies, and radiation imaging. The scope also encompasses a wide range of material classes, including inorganic functional materials, ceramics, glasses, polymers, alloys, composites, nanomaterials, hybrid materials, and advanced engineered systems containing rare earth and critical elements. Particular attention is given to compositional design, doping strategies, microstructure control, and performance optimization for targeted technological applications.
In addition, the session addresses upstream aspects of the critical materials value chain, including mineral resources, ore characterization, extraction technologies, mineral processing, beneficiation, refining, and separation techniques. Topics of interest include physical and chemical beneficiation methods, hydrometallurgical and pyrometallurgical processing, solvent extraction, ion-exchange separation, advanced refining technologies, and emerging environmentally responsible extraction approaches. Recycling, urban mining, and recovery of rare earth and critical elements from secondary resources are also key themes.
Overall, the session aims to foster interdisciplinary exchange among researchers, academics, and technology developers, highlighting both fundamental research and application-driven innovations that support sustainable, resilient, and secure technological development across the entire lifecycle of rare earth and critical materials.
