Nanomaterials are defined as materials with at least one external dimension ranging from 1 to 100 nanometers. They can occur naturally, result from combustion reactions, or be intentionally engineered for specific applications. The physical and chemical properties of nanomaterials often differ from those of their bulk counterparts. Widely employed across various industries, from healthcare and cosmetics to environmental conservation and air purification, nanomaterials offer the capability to design materials with precise functions.
Nanotechnology, a field of study and research, is dedicated to creating entities on the scale of atoms and molecules, including materials and devices. The scale, measured in nanometers is approximately ten times the diameter of a hydrogen atom. Nanotechnology holds promise for enhancing energy efficiency, contributing to environmental cleanup, and addressing significant health challenges.
