0.01 to 10 Nanometers: The Fascinating World of Nanoscale
Introduction
The nanoscale, which spans from 0.01 to 10 nanometers (nm), is a fascinating realm where the rules of the macro world no longer apply. At this scale, materials exhibit unique properties that are not seen in their bulk forms. In this article, we will delve into the world of 0.01 to 10 nanometers, exploring the properties and applications of materials at this scale.
The Nanoscale: A Brief Overview
A nanometer is one billionth of a meter. To put this into perspective, the diameter of a human hair is approximately 80,000 nm. The nanoscale is a region where the properties of materials are influenced by their size, shape, and surface chemistry. At this scale, materials can exhibit enhanced mechanical, thermal, electrical, and optical properties.
