What is the definition of nanoscale materials?
Nanoscale materials are defined as a set of substances where at least one dimension is less than approximately 100 nanometers.
How small is a nanometer compared to a millimeter?
A nanometer is one millionth of a millimeter, approximately 100,000 times smaller than the diameter of a human hair.
Why are nanomaterials of interest?
Nanomaterials are of interest because at this scale unique optical, magnetic, electrical, and other properties emerge.
What are the four ways to classify nanomaterials?
- Natural or man-made (engineered) 2) Synthetically produced or by-products 3) Organic or inorganic 4) By size; shape; surface properties; or functionalization.
What is the potential of nanomaterials in terms of functionalities?
Nanomaterials have the potential to revolutionize the ways in which materials and products are created and to access a wide range and nature of functionalities.
How are nanomaterials described based on their dimensions?
Nanomaterials are characterized by at least one dimension in the nanometer range.
