The effect of a dimethyl sulfoxide (DMSO) additive on the gelling behavior of a layered silicate has been investigated by means of a systematic combination of experimental and computational approaches. Langmuir-Blodgett monolayers of Laponite at the air-water interface show an isotropic structure with the layers forming a pseudo-hexagonal packing in the absence of DMSO. When DMSO is added to the subphase, the layers stack together to form a lamellar structure with the sheets strongly tilted with respect to the water/air interface. A DMSO molecule intercalates between two adjacent layers in such a way that the sulfoxide groups of the intercalant align at both sides of the lamella. The X-ray reflectivity (XRR) profile shows that the lamellar structure extends up to about 3 nm in depth from the interface in the absence of DMSO, while in the presence of DMSO the lamellar structure has a thickness of only about 2 nm. Small-angle X-ray scattering (SAXS) measurements performed on the Langmuir-Blodgett films show that the lamellar packing of the layers leads to a decrease of the in-plane structure of the material, more particularly in the direction perpendicular to the water/air interface. Molecular dynamics (MD) simulations of the Laponite/DMSO systems in the liquid-crystalline state confirm that DMSO molecules penetrate between two adjacent layers, as suggested by the XRR measurements, and form hydrogen bonds between the sulfoxide moieties of the DMSO molecules and the silanol groups of the Laponite layers. MD simulations show that the Laponite lamellar stacking is very stable at high temperatures, where the system is only slightly perturbed by the presence of DMSO.Q: How to convert an array of numeric strings into a single string of strings in PHP?
