This renewal award by the Solid State Materials Chemistry program in the Division of Materials Research to University of South Carolina addresses the discovery and the crystal growth of new materials by utilizing hydroxide fluxes as a synthetic strategy in preparing new complex oxides in single crystal form. Many important physical properties that enable the functioning of new electronic devices, data storage materials, battery components and superconductors are found in oxide materials containing transition metal elements. This is a versatile group of chemical compounds that can be selectively modified to exhibit desirable physical properties that will lay the groundwork for new devices and applications of the future. With this award, Professor zur Loye will be developing advanced methods for synthesizing new oxides to determine the atomic structure of these materials, to investigate their electronic and magnetic properties, and to enable their utilization in a variety of applications. The proposal focuses on the discovery of new materials and the training of the next generation researcher in the US. These two goals will be accomplished by using crystal growth in hydroxide fluxes as a synthetic strategy to prepare complex oxides, to discover new materials, and to provide a valuable educational experience for students from undergraduate to graduate and postdoctorate. The scientific goals focus on expanding and improving the approach of single crystal growth as a means of exploring phase space for materials discovery, while the teaching goals will assure the education of a wide range of individuals, including those from underrepresented groups, in the area of solid state and materials chemistry.

这项由南卡罗来纳大学材料研究部固态材料化学计划颁发的续展奖项致力于利用氢氧化物助熔剂作为合成策略来发现和生长新材料，以制备单晶形式的新复合氧化物。在含有过渡金属元素的氧化物材料中发现了许多重要的物理性质，使新的电子设备、数据存储材料、电池组件和超导体能够发挥作用。这是一组用途广泛的化合物，可以选择性地进行修饰，以显示出理想的物理性能，为未来的新设备和应用奠定基础。通过这一奖项，Zur Loye教授将开发合成新氧化物的先进方法，以确定这些材料的原子结构，研究它们的电子和磁性，并使它们能够在各种应用中使用。该提案的重点是新材料的发现和美国下一代研究人员的培训。这两个目标将通过使用氢氧化物熔剂中的晶体生长作为一种合成策略来实现，以制备复杂的氧化物，发现新材料，并为从本科生到研究生和博士后的学生提供宝贵的教育经验。科学目标侧重于扩大和改进单晶生长方法，将其作为探索相空间以发现材料的一种手段，而教学目标将确保在固体和材料化学领域对广泛的个人进行教育，包括那些来自代表不足的群体的个人。
