Nanomaterial

NAN-oh-muh-TEER-ee-uhl /ˈnænoʊməˌtɪəriəl/
nounC2GRE
formalscientifictechnical

A material with at least one dimension in the nanoscale (1-100 nanometers), exhibiting unique properties due to its small size.

The defining characteristic is size at the nanoscale, which often leads to quantum mechanical effects and drastically different properties compared to bulk materials.

The story behind the word. The word 'nanomaterial' is a modern compound, combining the Greek prefix 'nano-' (from 'nanos,' meaning 'dwarf' or 'extremely small') with the Latin-derived word 'material' (from 'materia,' meaning 'matter'). The 'nano' prefix denotes a scale of one billionth (10^-9), so a nanomaterial literally refers to 'dwarf matter' or material at an incredibly tiny scale, where its properties can become extraordinary.

Word relationships

  • nanoparticle: A particle with dimensions in the nanoscale, often a component of a nanomaterial.
  • nanostructure: A structure with dimensions in the nanoscale, often referring to the arrangement rather than the bulk material.
  • bulk material: Material at macroscopic scales, where nanoscale properties are not observed.

Commonly confused with

  • Micro-material: Micro-materials are at the micrometer scale (10^-6 m), larger than nanomaterials (10^-9 m), and generally do not exhibit quantum effects.

Word family

  • nano (prefix): Extremely small; one billionth (10^-9).
  • nanotechnology (noun): The branch of technology that deals with dimensions and tolerances of less than 100 nanometers, especially the manipulation of individual atoms and molecules.

Collocations

  • carbon nanomaterial
  • metallic nanomaterial
  • polymeric nanomaterial
  • nanomaterial synthesis

Example sentences

  • "Researchers are developing new nanomaterials for applications in medicine, electronics, and energy." Discussing advanced materials.
  • "The unique optical properties of this nanomaterial make it ideal for advanced display technologies." Explaining unique properties.
  • "Carbon nanotubes are a well-known type of nanomaterial with exceptional strength and conductivity." From a scientific report.

Memory hook

Think of 'NANO-material' as 'NANO' (tiny) 'MATERIAL' – so small it's like dwarf matter. NANO-material: tiny matter

When not to use

Do not use 'nanomaterial' for any small material; it specifically refers to materials engineered at the 1-100 nm scale.

Fun facts

  • The concept of nanotechnology was first introduced by Richard Feynman in his 1959 lecture 'There's Plenty of Room at the Bottom.'
  • Some everyday products already contain nanomaterials, such as certain sunscreens (zinc oxide nanoparticles) and self-cleaning windows.
