Despite the latter processes, there is no major loss of the phonon mode intensity in the superionic state, and there is no strong correlation between the phonon spectra and the increased diffusion … WebPhospholipids undergo hop diffusion Fujiwara et al. 1073 warranting the use of single gold particle tracking to study DOPE movement in a time window of 100 ms. …
Webenced the hop length, hop height, and hop duration, suggesting that the near-surface 3D diffusion was not simply Brownian. As shown in Fig. 4(a), for the more repulsive FS and NH2-50% surfaces, the distributions of hop length (i.e., the lateral distance between successive surface encounters during flights) exhibited a heavy tail
