“…14 Ganbold et al 126 As already observed for the viscosities reported by the two groups the data significantly deviate from the measured values reported in the present work. The conductivities deviate by 27% 76 and between 55 and 72% 126 and are therefore not included here for a comparison study. The ionic conductivity can be estimated assuming an uncorrelated contribution of the individual species to the total ionic conductivity using the Nernst-Einstein (NE) equation:…”

The low-viscous tricyanomethanide ([TCM]À )-based ionic liquids (ILs) are gaining increasing interest as attractive fluids for a variety of industrial applications. The thermophysical properties (density, viscosity, surface tension, electrical conductivity and self-diffusion coefficient) of the 1-alkyl-3-methylimidazolium tricyanomethanide [C n mim][TCM] (n = 2, 4 and 6-8) IL series were experimentally measured over the temperature range from 288 to 363 K. Moreover, a classical force field optimized for the imidazolium-based[TCM] À ILs was used to calculate their thermodynamic, structural and transport properties (density, surface tension, self-diffusion coefficients, viscosity) in the temperature range from 300 to 366 K. The predictions were directly compared against the experimental measurements. The effects of anion and alkyl chain length on the structure and thermophysical properties have been evaluated. In cyano-based ILs, the density decreases with increasing molar mass, in contrast to the behavior of the fluorinated anions, being in agreement with the literature. The contribution per -CH 2 -group to the increase of the viscosity presents the following sequence: The experimentally determined self-diffusion coefficients of the cations are in good agreement with the molecular simulation predictions, in which a decrease of the self-diffusion of the cations with increasing alkyl chain length is observed with a simultaneous increase in viscosity and for the longer alkyl lengths the anion becomes more mobile than the cation.

“…As seen, our density measurements agree closely with those of Fröba et al [17] and Królikowski et al [1], but also the agreement with other literature data is within the expanded (k = 2) combined uncertainties of the measurements. The viscosity determinations show generally much greater disparities; here our measurements agree best with those of Domań ska et al [19], while the most recent data of Ganbold et al [18], which can be unfortunately considered less reliable because of unknown water content in their sample, deviate the most. The value of refractive index at T = 298.15 K measured by us for pure [EMIM][TCM] (n D ¼ 1:51227) agrees within experimental uncertainty with those determined by Fröba et al [17] (n D ¼ 1:51217, linearly interpolated between T = (293.15 and 303.15) K) and Neves et al [16] (n D ¼ 1:51236), but the value (n D ¼ 1:5116) interpolated from measurements of Koller et al [14] deviates significantly.…”

“…More exotic substances like ionic liquids can be extensively studied by NMR. In order to more completely understand the dynamics of the medium, a complex approach to the study of dynamics can be attempted . This can include spectroscopy, relaxometry and dNMR as well as non‐NMR measurements such as conductivity and viscosity measurements.…”

NMR diffusion measurements (or dNMR) provide a powerful tool for analysis of solution organization and microgeometry of the environment by probing random molecular motion. Being a very versatile method, dNMR can be applied to a large variety of samples and systems. Here, a brief introduction into dNMR and a summary of recent advances in the field are presented. The research topics include restricted diffusion, anisotropic diffusion, polymer dynamics, solution structuring and dNMR method development. The dNMR studied systems include plants, cells (cell models), liquid crystals, polymer solutions, ionic liquids, supercooled solutions, untreated water, amino acid solutions and more. It is demonstrated how a variety of dNMR methods can be applied to a system to extract the data on particular structures present among, formed by or surrounding the diffusing particles. It is also demonstrated how dNMR methods can be developed to allow probing larger geometries, low sample concentrations and faster processes. Copyright © 2016 John Wiley & Sons, Ltd.
