TOPIC
▸　Micro-Nano Tribology Opened Up by MEMS Technology 

❝　Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion. The history of humanity's struggle with friction goes back to ancient Egypt. If you carefully watch the mural that transporting a huge stone statue drawn at the era, you can find a man pouring oil at the tip of a sled to reduce friction. Amazingly, we still do not understand why friction occurs and why wear occur very well, even in the 21st century. Friction is difficult to study because the contact area is normally hidden from view. Thus, the problem with this research field is that R&D is done without direct evidence, e.g., "We try to find out why friction occurs without observing what happens at the contact area" or "We sell lubricants that happen to be high performance without observing how they work". To address those problems, I fabricate a micro-machine (MEMS: Micro Electro Mechanical System), and put it into TEM (Transmission Electron Microscope). That's how I successfully obtained the important physical parameters. In the lecture, I will show some of my cutting-edge research results about the surface science. Additionally, I will explain what else you need to work on besides conducting experiments.　❞
