“…Visual observation of the montmorillonite clay with Atto 550 NHS ester revealed that addition of this dye decreased viscosity and increased fluidity. The latter was related to decrease of surface tension of montmorillonite clay due to addition of DMSO which surface tension is significantly lower than that of water (71.9 and 42.3 mN.m −1 (at 303.2 K) for water and DMSO, respectively) 22 . Due to the increased fluidity (fast particle movement), the confocal LSM measurements was performed without rubber gasket, covering the clay by glass cover that reduce thickness of the sample (~ 300 µm).…”

Cryogenic electron microscopy became a powerful tool to study biological objects. For non-biological objects (solutions, gels, dispersions, clays), the polemic about interpretation of cryogenic microscopy results is still in progress splitting on two contradictive trends: considering structure as a near-real state of the sample or as freezing artefacts. In this study, a microstructure of a range of stable aqueous solutions and dispersions (agar, kaolin, montmorillonite, nanoparticles) was investigated by means of cryo-SEM and confocal LSM in order to compare cryo-fixed and unfrozen structures. Noticed correlation between these two methods for studied systems (agar, kaolin, montmorillonite, NPs) allowed to state that ordered microstructure is an inherent feature of these systems. Some inconsistencies in microstructure dimensions were discussed and prescribed to the differences in the bulk and interface layers. Supposedly, NaCl solutions also possess dynamic (femtosecond level) microstructure of neat water clusters and solvated Na+ and Cl- ions that may have an impact on electrolyte abnormal properties.

We present the extension of our all-atom force field BILFF (Bio-polymers in Ionic Liquids Force Field) to the co-solvent dimethyl sulfoxide (DMSO). BILFF already includes force field parameters for several imidazolium- and triazolium-based ionic liquids, water, and the bio-molecule cellulose. DMSO is known to increase the cellulose solubility of [EMIm][OAc] when applied as an additive. Our focus is on a correct reproduction of the hydrogen bonds in the ternary system of [EMIm]$$^+$$ + , [OAc]$$^-$$ - , water and DMSO compared to ab initio molecular dynamics simulations. For this purpose, the results from force field MD simulations such as radial and distance–angle distribution functions are compared with the reference AIMD simulation. Based on this, the force field parameters (starting from OPLS–AA) are iteratively adjusted. Four systems, pure and aqueous DMSO as well as DMSO in pure and aqueous [EMIm][OAc], are considered and additionally compared to DMSO-free [EMIm][OAc] systems. A very good agreement with respect to the microstructure of the quantum chemical reference simulations as well as to experimental data such as density, diffusion coefficients, enthalpy of vaporization, compressibility and thermal expansion coefficients can be observed over a wide temperature range. BILFF thus enables accurate simulations of larger systems of solvated cellulose in (aqueous) [EMIm][OAc] and the co-solvent DMSO.
