Development of Advanced Materials

Modern ceramics processing is related to nano-dimensions. One of the processing method is the sol-gel process. In the slurry, complicated interactions between charged particles, polarized molecules and ions occur. Also, due to the relaxation of the atoms, the free energy is different, which means that the phase diagrams have to be revised. Further knowledge is necessary in order to improve the final ceramic.

Inter-nano-composite: Alumina-Magnesia-particles

The atomic structure of Interfaces has strong influence on properties of materials.
The Molecular Dynamic Method can principally predict most properties of materials and, hence is an important tool for development of advanced materials.
