9. There exist a great number of special terms formed with the prefixe nano-:

 

Ex. nanoparticle	- a particle with dimensions less than 100 nanometres;
nanowire	- a nanoscale rod made of semiconducting material, used in miniature
	transistors and some laser applications;
nanodot	- a microscopic cluster of several hundred nickel atoms that can be used to
	store extremely large amounts of data in a computer chip.
