buy nanoporous materials

Description

 We are conducting a scientific reserarch, and in our project we need a cylindrical nanoporous materials which is about 6cm long, cross sectional radius is about **6mm, the size of pores is less than *0nm. At the same time, we need to make a hole on the surface and insert an electrode in it. Besides, the material must be a kind of insulated materials so that it would not have any effect on our mearsurement.
