Preface

*Rare Earth Elements - Emerging Advances, Technology Utilization, and Resource Procurement* presents a compelling array of research detailing aspects of the technology and utilization of rare earth elements and similar elements. Chapters in the section on "Emerging Advances and Technology" discuss coordination compounds involving lanthanides to develop luminescent turn-off sensors, gold mineralization in Egypt, concentrated hydrochloric acid leaching of steenstrupine to obviate silica gel formation, luminescent materials with turn on and radiometric sensory response based on coordination compounds, prediction of solubility and miscibility parameters of the bismuth–arsenic complex and amorphous mineral compounds using molecular dynamic simulation, rare earth elements in new advanced engineering applications, and a radon emanation measurement system for South African communities. The section on "Utilization and Resource Procurement" presents an evaluation of rare earth element mine sites for environmental impact.

Each chapter provides a unique perspective on the uses or technology associated with rare earth elements. Collectively, they showcase the diversity of research involving these elements.
