"Recent Journal Publications" updated

Hi, Welcome to my website.

My main research interests are focused on the synthesis, evaluation and application of a class of nanolayered ternary compounds-MAX phases, with Ti3SiC2 (titanium silicon carbide) as their representative. We have successfully synthesized single phase  and fully dense Ti3SiC2 in a short reactive sintering process (15 minutes) with Pulse Discharge Sintering (PDS) technique.

We have also discovered some interesting physical phenomena, such as spontaneous growth of Pb nanowhiskers from brass surfaces, and the spontaneous growth of metal (Ga) nanoribbons as well as microbundles of metal nanotubes from the surface of a ternary compound Cr2GaC.

For details please refer to the right columns or click the buttons on the top of this page.

Thanks.

   Biography

After a joint degree program between the Chinese Academy of Sciences (CAS) and The University of Vienna (Universitaet Wien), I have gained my Ph. D in 1992, after 3 years study at the Institute of Metal Research (IMR), CAS and one year at The University of Vienna. Shortly after appointed a research associate at the IMR, CAS, I was invited to the University of Vienna for  postdoctoral research at the beginning of 1993. In the summer of 1994, I was invited to Toyohashi University of Technology, Toyohashi, Japan, where I spent 2 and a half years for postdoctoral study under the financial support for the Daiko Fundation and the Japan Society for the Promotion of Science (JSPS).

In 1997 I joined the Tohoku National Industrial Research Institute, which was reorganized to be the present  National Institute of Advanced Industrial Science and Technology in 2001. At the beginning of 2004, our group moved from the AIST-Tohoku (Sendai) to the present AIST-Chubu (Nagoya). Shortly after the moving, I went on my sabbatical stay at Drexel University for one year.
