Insight is given on the type of ion-pairs that could be formed in EC/DMC by Li-salts LiTDI, LiFSI and LiPF₆.

The anisotropy of the solvent self-diffusion coefficient within suspensions of nanoparticles is measured by ${}^1\mathrm{H}$ nuclear magnetic resonance with pulsed field gradient and used as a new procedure to detect nematic ordering. The potentiality of this method is illustrated using aqueous clay dispersions whose nematic ordering was already detected by ${}^{23}\mathrm{Na}$ quadrupolar splitting.

¹H NMR pulsed gradient spin echo attenuation and water density profile analysis by magnetic resonance imaging are both used to determine the mobility of water molecules confined within a porous network of compacted kaolinite clay sample (total porosity of ∼50%). These two complementary experimental procedures efficiently probe molecular diffusion within time scales varying between milliseconds and few hours, filling the gap between the time scale of diffusion dynamics measured by traditional quasi elastic neutron scattering and through-diffusion methods. Furthermore, magnetic resonance imaging is a nondestructive investigation tool that is able to assess the effect of the local structure on the macroscopic mobility of the diffusing probe.
