Abstract Submitted to the    NANOTUBE'04 Conference:

The possibility of a superconductivity in nanotubes is the one of the most important problems. The nature of a superconductivity is the electron-electron interaction. On the other hand elec-tron-electron interaction is exhibited in electronic transport properties of conductors in normal state so-called interaction effects (IE). IE are connected with the correction to density of states of conduction electrons as a result of quantum interferences of electrons at their diffuse motion in disordered conductors. It is shown that IE correction to X are dominated by quantum correc-tion to magnetic susceptibility X(T) for interaction electrons (interaction effects-IE). The effective interaction between electrons for arc-produced sample of multiwall carbon nanotubes (A-MWNTs) and graphite are repulsion and the electron-electron interaction l_c are estimated to be l_c ~ 0.26 for A-MWNTs and l_c ~ 0.1 for graphite. An additional negative contribution DR(B) to R(B) was found. It is show n that DR(B) at B > 0.7 T for multiwall carbon nanotubes prepared by catalyst method (C-MWNTs) and soot is connected with electron-electron interaction similarly to DR(T) for graphite. In this report we give Report-Review new results in field of superconductivity in ropes of single wall carbon nanotubes and MWNTs
