Project Title: Selective Synthesis, Structures, and Properties of Oxynitride Materials PART 1: NON-TECHNICAL SUMMARY Modern society is enabled by technology; new materials enable modern technologies. With support from the Solid State and Materials Chemistry program in the Division of Materials Research, this project progresses the science of materials synthesis to expand a new and emerging family of materials that couple metal ions between oxygen and nitrogen atoms. The approach taken in this project imparts new types of bonding in materials that yield novel functionality. The materials of focus in this project present opportunities to advance applications in magnetism, polar materials, and electrochemical energy storage. This project also integrates a broadly impacting educational outreach program to develop and distribute Science, Technology, Engineering, and Mathematics (STEM) education activity kits that provide 90-minute authentic research experiences in the field of the chemistry of functional materials to secondary schools throughout Colorado. PART 2: TECHNICAL SUMMARY With support from the Solid State and Materials Chemistry program in the Division of Materials Research, this project seeks to selectively synthesize new oxynitride-based materials and to understand the resulting structure/property relationships. For the heteroanionic materials that have been discovered, the result of having two anions enables enhanced and unique properties relat
