What is Nanotechnology in civil engineering?

A nanometer, nanometer is a unit for measuring lengths, are used to measure lengths very short and the amount of 910meter. 

It has many uses in physics and chemistry. A nanometer is a billionth of a meter. This module is used to measure very small lengths which are often the dimensions of corn, symbolized by name or nm. Nano now uses the term significance of the terms of reference for the technical work within this area, which is called nanotechnology, which are often in surface chemistry or semiconductor industry.
