Properties and Structure of Materials - Nano-materials Flashcards
What is nanotechnology?
The study of materials on the
nanoscale.
What is a nanometre?
A nanometre (nm) is a billionth of a metre
(10-9 m).
What are nano-materials?
Nano-materials are materials with nanoscale features that give the material useful and important properties.
Where are nano-materials found?
Nanomaterials can be found in nature, manufactured in the laboratory or engineered from other materials.
What are nanoparticles?
Nanoparticles are particles with diameters of about 1-100 nm.
Are the properties of nanoparticles the same as the material they are made from?
The properties of nanoparticles can be different from the bulk material that they are made from.
Are nanoparticles good or bad?
Nanoparticles can travel through the air, through skin and even though cells, making them both potentially useful and dangerous for humans.
