Possible chemical sensor applications of nonmetallic nanotubes are interesti

junctions caused by interjunction temperature differences) are very sensitiv

I notice that the structure of those organic nanotubes may change during
different PH value. What I am looking at right now is Nano Lett. 2, 887-889,
2002. And the sugar nanotube is made by van der waals interaction that may be
weekley bonded. There isn't quite a few organic nanoTUBEs not nanorod or
something.
My interest is to find some nanotubes that has enough hollow space, let us
say, around 15A, but it is an insulator and stable at least at common chemical
environments.

what you mean? this was a proposed idea in our group that didn't get funding.
then none keep working on it.
The idea came from that nanotube bundle will be bent if you apply electric
voltages at both sides of bundles. This was published at science three years
ago. Then we proposed that if to put nanotube bundle into fluid, the flow will
bent the nanotube bundle and so that change the voltage over the bundle.

作者在文章里直接给出了carbon nanotube的retarded Green's function,见文章方程

没有固体物理基础,只学过一点基础量子力学,对carbon nanotube的特殊性质不熟悉。

But the pore size maybe too small for you.
I am pretty sure that there is quite a few organic nanotubes because
I attended a student seminar, and the student presented several
organic nanotubes and how they assemble ...
If you really need that, I can try to find the person to get the reference.

For the flame synthesis of carbon nanotubes, can the CNT react easily with
oxygen? I noticed that people pass inert gases through the reactor after the
test as the cooling gas in many research. My concern are:
1. I am not clear about the chemical properties of carbon nanotubes, and
neither can I find the related literature.
2. Assuming that it can be oxidized or even burned under the after-tests'
environment with the oxygen, how can it survive during the test where the
exit of oxygen is unavoida
