Synthesis, characterization and theoretical description of metastable transition metal oxides and oxide nitrides

该项目的目的是开发钒、铌、钽、铬、钼和钨的亚稳氧化物和氧化氮化物的优化合成路线。此外，我们希望对亚稳相的形成及其向热力学稳定的多晶态转变的过程有一个基本的了解。我们所有小组在互补领域的合作是真正重要的。在项目期间，我们打算通过增加原位表征、理论和制备之间的反馈来优化合成路线。最后，亚稳态氧化物和氧化氮化物的合成应建立一个基于知识的概念，从而产生具有有趣物理性质的新材料。

The aim of this project is the development of optimized synthesis routes to metastable oxides and oxide nitrides of vanadium, niobium, tantalum, chromium, molybdenum, and tungsten. In addition, we want to obtain a fundamental understanding of the processes during genesis of the metastable phases and their transformation to thermodynamically stable polymorphs. The cooperation of all our groups, working in complementary fields, is of real importance. During the project we intend to optimize the synthesis routes by increasing feedback between in situ characterization, theory, and preparation. Finally, a knowledge-based concept for the synthesis of metastable oxides and oxide nitrides should be developed, leading to novel materials with interesting physical properties.
