Co2 Critical pointTHE invention of Light Microscope enables people  to  observe the "tiny world" and found out "bacteria" at that time. With the further development , SEM (Scanning Electron  Microscope) enhances our ability to observe the Micro-world even more. The biggest advantages of SEM are  high resolution  and DOF (Depth of Field), which can provide high quality images.

This project is to reveal the " small world" on various surfaces via SEM. Let us have an interesting trip about those "dirty world".
