on a sort of similar note, those of you with an interest in nano-tube technology may be interested in a recent publication in the respected Chemical Communications journal:
Dachi et al, Chem. Commun., 2007, 1733 "Electrochemical synthesis of metal and semimetal nanotube–nanowire heterojunctions and their electronic transport properties"
http://www.rsc.org/Publishing/Journals/CC/article.asp?doi=b614147aand everyone else on the TEF will be interested in their abbreviation of "Copper Nano-Tube" especially since Cu is the chemical symbol for copper. For those of you that don't have access to the paper, here is one of the figures from it.
http://www.rsc.org/ejga/CC/2007/b614147a-ga.gifThe paper repeats the above abbreviation in almost every line, with such gems as "formation of CuNTs depends on gold spattering", "CuNTs have an outer diameter of about 80 nm". I've heard of mouse's ears before, but thats ridiculous !
