On the afternoon of May 28th, 2018, Professor Dae-Eun Kim, from the School of Mechanical Engineering, Yonsei University in South Korea, visited the School of Mechanical Engineering and gave a report  on Understanding of Friction and Wear at the Micro-scale, he shared the contents of his research on wear characteristics of micro-scale systems (such as AFM tip, Silicon bushing, thin gold wire) and on Nano-lubricant for micro-scale devices (such as Micro-ball bearing application and MEMS application) to the students and peers who participated in this report meeting. To express that challenges in reduction of friction and wear continue to expand, he began his speech with the introduction of certain tribological issues where in precision mechanical components, friction and wear led to energy loss and failure, and where in extreme operating conditions, MEMS vacumm High temperature, liquid lubricants cannot be used.

Followed were a report on Tribology of Two-Dimensional Materials, giving by Professor Ma Tianbao, and a report on the Resolution Comprehensive System for in-situ Detection of Friction Energy Dissipation, giving by Professor Liu Dameng, Department of Mechanical Engineering in Tsinghua University.

Students had active communication with the presenters in the Q&A sessions of this reports meeting.
