Question

How much larger is a nanowhisker in diameter than an atom

Answer 1

Answer:

Nanoparticles are bits of a material in which all three dimensions of the particle are within the nanoscale: nanotubes have a diameter that's nanosize, but can be several hundred nanometers (nm) long or even longer.

Explanation:

A nanometer is one billionth of a meter (10-9 m). This is roughly ten times the size of an individual atom. For comparison, 10 NM is 1000 times smaller than the diameter of a human hair. How small is that? “If a centimeter is represented by a football field, a nanometer would be the width of a human hair lying on the field,” offers William Hofmeister of the University of Tennessee Space Institute’s Center for Laser Applications.

A cubic centimeter of material, about the size of a sugar cube, has the same surface area of a half a stick of gum. But if you fill that cube with particles that are 1 nanometer in size, the surface area of all those particles is an astonishing 6,000 square meters, nearly the surface area of 3 football fields.Nanofilms or nanoplates have a thickness that’s nanosize, but their other two dimensions can be quite large. These nanoparticles can be designed into structures of a specific size, shape, chemical composition and surface design to create whatever is needed to do the job at hand. They can be suspended in liquid, ground into a powder, embedded into a composite or even added to a gas.

For your Extra Knowledge I want to tell you:

Nanoscience is the study of things that are really really small.
