Nilima Nanotechnologies offers a wide range of nanotechnology based coatings with protective properties for various surfaces. Nanotechnology is the science and technology where dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm play a critical role.One nanometer (nm) is one billionth, or 10-9, of a meter. To put that scale in another context, the comparative size of a nanometer to a meter is the same as that of a marble to the size of the earth. Essentially, this is the engineering of functional systems at the molecular scale. It is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly.
