Unique properties of carbon and noncarbon nanotubes in reality stem from their nanosize and cylindrical form making them the quantum nanocylinders, in which all the electronic, hypersonic, and electromagnetic waves belonging to the gallery of whispering modes was shown jointly to circulate. Low attenuation and high frequency are the peculiar features of these waves that is capable to enhance strongly the electron-phonon, electron-photon, and phonon-photon interactions. IR and Raman spectra of single-walled BN nanotubes were calculated by ab-initio RHF/6G-31 method. Ordered arrays of nanotubes and nanotubular crystals was shown to form the ideal media for: 1) the room-temperature superconductivity (V.V. Pokropivny. Int.J.Nanotechnology. 1, 77 (2004)); 2) the novel physical phenomenon, the photo-acousto-electronic super-resonance (V.V. Pokropivny. Mat.Sci. & Eng. C. 25, 771 (2005)); 3) the new piezo-acousto-electric transducer of hypersound in extremely high-frequency tera-hertz range (V.V. Pokropivny, et al. Physica E: Low Dim. Struct. 37, 283 (2007)). Physical background of these phenomena was surveyed.
