Surface Contamination in Small Systems

Surface Contamination in Small Systems

The ratio of the volume to the surface area of a surface has length dimension and is a representative of the system’s length scale. Length scale [m]= Volume [m3] / Surface area [m2] For systems in micro and nano scales this ratio is 10-6 and 10-9 m, respectively. This simple calculation shows the importance of […]

Lab safty from the view point of the undergraduate student, Min

Storing            There are three types of chemicals in the lab I was working; organic solvent, inorganic acid and organic acid.

How different is my world from the island country of Lilliput?

 From my childhood, I know the island country of Lilliput in which the tiny people of Galliver story are living is different from my world from different aspects. Now after several years working in the area of micro and nano sciences I can understand all great differences between these two worlds much better. I can […]
