Nanomaterials

Nanomaterials

Nanomaterials (pronunciation: /ˈnænoʊməˌtɪəriəlz/) are materials with structural components smaller than 100 nanometers. They are often classified into nanoparticles, nanotubes, nanorods, nanowires, nanosheets, and nanoplates.

Etymology

The term "nanomaterials" is derived from the Greek word "nanos", meaning dwarf, and the English word "material", which refers to the substance or substances out of which a thing is or can be made.

Types of Nanomaterials

• Nanoparticles: These are materials that are between 1 and 100 nanometers in size. They are often used in medicine, physics, and chemistry due to their unique properties.

• Nanotubes: These are cylindrical nanostructures with a diameter of a few nanometers. They are often used in electronics, optics, and other fields of materials science.

• Nanorods: These are rod-shaped structures with diameters typically under 100 nanometers. They are often used in optoelectronics, solar cells, and catalysis.

• Nanowires: These are wires with a diameter on the order of a few nanometers. They are often used in nanotechnology, physics, and materials science.

• Nanosheets: These are two-dimensional materials with a thickness of a few nanometers. They are often used in electronics, optics, and catalysis.

• Nanoplates: These are plate-like nanostructures with a thickness of a few nanometers. They are often used in optics, electronics, and catalysis.

Related Terms

• Nanotechnology: The manipulation of matter on an atomic, molecular, and supramolecular scale.

• Nanoscale: A length scale of 1–100 nanometers.

• Nanoscience: The study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales.

• Nanomedicine: The medical application of nanotechnology.
