The study focuses on exploring the impact of variations in kaolinite surface characteristics on rheological manifestations by employing parallel pore models incorporating diverse kaolinite surface configurations. Equilibrium molecular dynamics (EMD) and nonequilibrium molecular dynamics (NEMD) simulations were conducted to investigate the physical properties of kaolinite under zero shear conditions and various shear rates, respectively. The wettability of different surfaces of kaolinite leads to a regular distribution of water molecules, affecting the pore spacing after EMD equilibrium, resulting in differences in water molecule self-diffusion coefficient and viscosity, exhibiting a small pore effect. In the simulation, the interaction between two parallel kaolin particles was determined to weaken with increasing separation distance. Non equilibrium molecular dynamics (NEMD) simulations were used to analyze the migration of water molecules under shear in different pore types. The viscosity of water molecules is affected by shear rate and separation distance and decreases to varying degrees as they increase. Finally, the yield stress of kaolinite particles was calculated using the Bingham model.

The hydration behavior of each of bicyclic solutes under study was discussed in comparison with that for the related chiral dimethyldiethylglycoluril (<em>trans</em>-DMDEGU, being the tranquilizer <em>albicar</em>) using the results of previously performed calorimetric experiments. It is established that the temperature-dependent balance of hydrophilic and hydrophobic forces in the process of a solute hydration is determined not only by the number of bulkier alkyl substituents in the molecule of the racemic tetraalkylated glycoluril-derivative, but also by the stereochemical peculiarities of their <em>N</em>-locations.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"437 ","pages":"Article 128564"},"PeriodicalIF":5.2,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145154158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
