Hi,

Will you be so kind to help me with my studying (it is not a homework) and give me a definition of the following (some of the following) words. There are some sentences, but I need the definition of the words in bold, not of the whole sentence.

It will be very nice if you write also in what field of science the given definition is used.

1) Controlled orientation
2) Heteronanotube
3) decomposition
4) superlattice
5) acceptor...
