High frequency conductivity of hot electrons in carbon nanotubes

We give a multiple-cycle quantum interference model and obtain magnetoresistance (MR) expression in the framework of the weak localization. The MR expression based upon finite phase-breaking length Lφ can explain well several experimental results about distinct negative magnetoresistance of carbon nanotubes. The higher-order oscillation peaks with magnetic flux exist in the MR can also be explained by our model. And a new method to measure the phase-breaking length Lφ of the single-wall carbon nanotubes has been proposed.

The composition of silicate paint developed for rehabilitation of buildings and structures and including white Portland cement, binder based on sodium liquid glass and complex additive with nanodispersed additives does not require the use of traditional silication. Modifying the composition of coating with multi-walled carbon nanotubes has provided a coating with a shielding effect weakening high-frequency man-made electromagnetic radiation. Moreover, the use of carbon nanotubes has provided the increase of density of the coating structure, improved the physical and technical characteristics of cement and silica coating and ensured the durability of the repair coating 3,5 times compared to its analogues.
