Impedancemetry methods have been used to measure the temperature dependence of the electrical conductivity of nanoparticles using the example of poorly studied vanadium pentoxide synthesized in porous glass nanochannels. The estimates of the band gap and the values of the specific electrical conductivity of nanoparticles of the semiconducting phase V2O5 are given. The reasons for the narrowing of the band gap of V2O5 localized in glass nanopores are discussed on the basis of the concept of lone electron pairs and the processes of charge transfer.

The temperature dependences of the dielectric spectra of Ag2S nanocrystallites synthesized inside the channels of nanoporous glasses NPG-17 with an average diameter of filamentous pores of 17 nm are studied. The macroscopic mechanism for the occurrence of the frequency dependence of the electrical response of a nanoporous structure NPG+Ag2S is proposed. Formation of the model of mechanism is based superionic phase transition in Ag2S nanocrystallites fixed inside the channels of nanoporous glass is discussed.
