Multifractal nature of heterogeneous dynamics and structures in glass forming ionic liquids

Communication: Probing the existence of partially arrested states in ionic liquids

“…10,[13][14][15][16][17][18][19][20][21] Many researchers have previously observed a slower diffusion of the smaller anions in RTIL, either by experiments 21 or by molecular dynamics (MD) simulations. 10,[13][14][15][16][17][18][19][20] The most common explanation appeals to the dynamics along the direction of the carbon located between the two nitrogens in the imidazolium ring with a marginal dependence on the anion. 22,23 However, the present work offers an alternative explanation for this observation on RTIL, one that is supported by an analysis of the simulation results in light of the SCGLE theoretical predictions.…”
