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氮氧化物的优化合成路线。此外，我们希望获得一个基本的了解过程中的亚稳相的成因和它们的转化为结晶稳定的多晶型。我们所有集团在互补领域开展的合作具有真实的重要性。在该项目中，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，一个知识为基础的概念，亚稳氧化物和氮氧化物的合成应发展，导致新的材料与有趣的物理性能。

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.
