Functional Materials

Membranes
Microporous SiBC membrane for hydrogen separation – Reference: R. Hauser, S. Nahar-Borchard, R. Riedel, Y. H. Ikuhara, Y. Iwamoto, „Polymer-derived SiBCN ceramic and their potential application for high temperature membranes“, Journal of the Ceramic Society of Japan, Vol. 114, pp. 524-528, 2006.

Further research topics are related to the development of materials suitable for applications in the fields of microelectromechanical systems (MEMS), optoelectronics (LEDs), pressure, temperature and gas sensors as well as thermoresistant ceramic membranes for high temperature gas separation.

Gas sensors
Gas sensor based on polycrystalline In2O3 – Reference: A. Gurlo, R. Riedel, „In situ and operando spectroscopy: an emerging methodology for assessing mechanism of gas sensing (review)“, Angewandte Chemie – International Edition, Vol.46, pp.3826-3848, 2007.

Another main topic of the scientific activities deals with the correlation of material properties with the molecular structure of the preceramic polymer used.

The integration of state-of-the-art spectroscopic methods is applied to understand the mechanisms responsible for sensing and catalytic properties.
