In the 106th session sponsored by China Distinguished Materials Scientists Forum, Tian Yongjun, Academician of Chinese Academy of Sciences, was invited to give an academic report entitled "the hardening and toughening of diamond" in the lecture hall of University of Science and Technology Beijing on the afternoon of June 1st. Present at the lecture were Yang Renshu, President of University of Science and Technology Beijing (USTB), Wang Luning, Vice President of University of Science and Technology Beijing, leaders of many units under the Department of Material Science and Engineering (DMSE) of the USTB, as well as nearly 300 teachers and students. The academic report was presided over by Professor Qiao Lijie from Institute of Advanced Materials and Technology.

Before the forum, Vice President Wang Luning briefed the keynote speaker——Academician Tian Yongjun, who was awarded by President Yang Renshu a commemorative forum plaque for Chinese masters.

In bursts of enthusiastic applause, Academician Tian Yongjun focused his introduction on diamond, the hardest material in nature, in his systematic and in-depth report on the hardening mechanism of covalent materials, extra-hard nano twin diamond, the toughening mechanism of covalent materials, highly tough nano twin diamond composites, and future development prospects and opportunities. According to Academician Tian Yongjun, both academia and industry have always been striving to synthesize high-performance super-hard materials that are harder and tougher than natural diamonds. He also highlighted his studies in the synthesis of nano twinning in high temperature and under high pressure, and elaborated the technical difficulty and experimental results. He forecast that nano twin diamond composites would be very likely to be used in deep-sea drilling in the future.

The speech was concluded in warm applause from the students. The teachers and students said that the wonderful scientific research and sharing of Academician Tian enabled them to understand the current research and development of nano diamond, and to harbor the expectation of the possible future technological changes of nano twin diamond. We believe that due to today's lecture, more teachers and students will be inspired by Academician Tian's spirit to be bold to rise to challenges and make explorations.
