• model both describe dissipation in terms of the excitations of the phonon modes of a linear harmonic chain. Therefore, the two models agree that no resonant energy transfer can occur for very large speed, and friction drops to 0, as at the right side of Figure 6. However, the frictional features

• sidewall with π-conjugated organic compounds [9][10][11][12]. Considering sensors, particular attention has to be paid to the PL enhancement in aqueous media, like the complexation and resonant energy transfer (RET) from cyanine dyes to the SWNTs covered by anionic surfactants in water [12]. However, a

The interaction is evidenced by new optical features in the range of the intrinsic excitation of the dye because of resonant energy transfer from the dye to the SWNTs. In the mixtures of DOB-719 with SWNTs, a new

Due to the insulating SiO2 shell the gold core can only transfer the plasmonic energy to the Cu2O shell by resonant energy transfer and the electron–hole pairs generated by the
