  Primary mechanism governed the emerge of near-room-temperature
superconductivity in superhydrides is widely accepted to be the electron-phonon
interaction. If so, the temperature dependent resistance, R(T), in these
materials should be obey the Bloch-Gr\"uneisen equation, where the power-law
exponent, p, should be equal to exact integer value of p=5. From other hand,
there is a well-established theoretical result that the pure electron-magnon
interaction should be manifested by p=3, and p=2 is the value for pure
electron-electron interaction. Here we analysed the temperature dependent
resistance, R(T), for high-entropy alloy (ScZrNb)0.65[RhPd]0.35 and
highly-compressed boron and superhydrides H3S, LaHx, PrH9 and BaH12. In result,
we showed that high-entropy alloy (ScZrNb)0.65[RhPd]0.35 exhibited pure
electron-phonon mediated superconductor with p = 4.9. Unexpectedly we revealed
that all studied superhydrides exhibit 1.8 < p < 3.2. This implies that it is
unlikely that the electron-phonon interaction is the primary mechanism for the
Cooper pairs formation in highly-compressed superhydrides and alternative
pairing mechanisms, for instance, the electron-magnon, the electron-polaron,
the electron-electron or other, should be considered as the origin for the
emerge of near-room-temperature superconductivity in these compounds.
