This award will support collaborative research between Dr. Hugo Steinfink, University of Texas at Austin and Professor Jean-Pierre Wignacourt, Laboratoire de Cristallochimie et Physicochimie du Solide, Ecole Nationale Superieure de Chimie de Lille, France. The objective of the project is the synthesis and characterization of high temperature superconducting materials. In addition to ceramic preparative techniques, molten oxide chemistry will be used to prepare compounds with unusual oxidation states. Dr. Wignacourt's expertise in molten oxide systems will be a unique contribution to the synthesis and single crystal growth of new phases. The highly oxidizing conditions achievable in such a medium should yield new compounds of potentially great fundamental interest. When the compounds are synthesized, their crystal structures and physical properties will be evaluated. This project will utilize the expertise of both investigators in the areas of solid state chemistry, crystal structure determination and physical property evaluation.

该奖项将支持德克萨斯大学奥斯汀分校的Hugo Steinfink博士和法国国立化学高等学院晶体化学与固体物理化学实验室的Jean-Pierre Wignacourt教授之间的合作研究。该项目的目标是高温超导材料的合成和表征。除了陶瓷制备技术，熔融氧化物化学将用于制备具有不同氧化态的化合物。Wignacourt博士在熔融氧化物系统方面的专业知识将对新相的合成和单晶生长做出独特的贡献。在这种介质中达到的高度氧化条件将产生具有潜在重要意义的新化合物。当化合物合成后，将对其晶体结构和物理性质进行评价。该项目将利用两位研究人员在固态化学、晶体结构测定和物理性质评估领域的专业知识。
