New Research Fellow of the Humboldt Foundation at TU Darmstadt, Materials and Earth Sciences
Prof. Dr. Zhaoju Yu from the Xiamen University (P.R. China) is a new research fellow of the Humboldt foundation and guest in the Dispersive Solids group.
She is researching from molecular approach to advanced ceramic materials, from synthesis via processing to properties.
The main research interests of the group are directed towards the development of novel strategies suitable for the synthesis of inorganic, oxidic and non-oxidic materials with properties beyond the state of the art. The materials of interest are advanced oxidic and non-oxidic ceramics with extraordinary properties in terms of thermal stability, hardness and electronic structure. Therefore, synthesis methods such as polymer-pyrolysis, non-oxidic and oxidic sol-gel methods, chemical vapour deposition and novel high pressure methods have been further developed.
