In this study, we hypothesized that diacerein-loaded β-cyclodextrin-based nanosponge could be developed for their clinical applications in diabetes management. Here, diphenyl carbonate (DPC) was used as a crosslinker, while the formulation was optimized using the QbD approach as per industrial requirements. The final optimized formulation had a particle size, zeta potential, polydispersity index, percentage yield, entrapment efficiency, and drug loading in the range of 336.6 ± 5.3 nm, −22.4 ± 1.3 mV, 0.21 ± 0.03, 65.31 ± 3.8%, 87.18 ± 4.1%, and 29.06 ± 3.4%, respectively. Additionally, a solubilization efficiency study revealed that DCN solubility was increased by about 9.9-fold. The SEM images showed the spongy-porous structure of the nanosponge. FTIR, PXRD, and DSC studies confirmed suitable incorporation of diacerein in the nanosponge. <em>In vitro</em> release studies demonstrated sustained drug release up to 24 h.

However, conventional surfactants often lose effectiveness under harsh reservoir conditions. Ionic liquids, with tunable molecular structures, represent a promising alternative, though the role of specific functional groups on interfacial behavior remains insufficiently understood. This study investigates the effect of hydroxyl functionalization in imidazolium-based ionic liquids on solid–oil–brine interactions relevant to enhanced oil recovery. Two hydroxylated (IL 2, IL4) and two non-hydroxylated (IL1, IL3) ionic liquids were systematically evaluated using contact angle and IFT measurements, zeta potential analysis, ATR-FTIR spectroscopy, and core-scale spontaneous imbibition tests. Hydroxylated ionic liquids consistently outperformed their non-hydroxylated counterparts. On aged mica, IL1 reduced the contact angle from 60.44° (Blank) to 44.19° while IL2 reduced the contact angle to 37.3°, reduced IFT to ∼15.6 mN/m under high salinity, and produced more negative zeta potentials (down to −15.73 ± 3.55 mV), reflecting enhanced adsorption and electrostatic stabilization. FTIR confirmed enhanced IL–crude oil hydrogen bonding. Core-scale imbibition tests in Berea sandstone validated these results, with the hydroxylated ILs achieving &gt;63% recovery versus &lt;40% for non-hydroxylated ILs and ∼ 10% for brine.

Due to its outstanding properties, such as one-dimensional (1D) fibrous morphology, porosity, high aspect ratio, and large surface area, sepiolite possesses advantage of displaying a stronger electric field response and improved dispersion stability. Its unique crystal structure and strong secondary interactions among fibers lead sepiolite to be tightly packed as bundles of fibrous nanostructures. However, adequate disaggregation of sepiolite bundles into individual fibers is required to utilize the properties of sepiolite at a high level. In this study, various processes, including purification, lyophilization, and mechanical grinding, were applied to raw sepiolite to ensure the disaggregation of sepiolite fibers and improve porosity through a simple physical process, prior to preparing sepiolite-based ER fluids. The structural, morphological, dielectric, and dispersion stability properties of treated sepiolite samples were characterized by various techniques. The effects of the applied processes on the ER performance of the sepiolite dispersions prepared in polydimethylsiloxane were investigated via steady and oscillatory shear tests. The strongest yield stress (400 Pa at 2.5 kV/mm), excellent dispersion stability (97 % at the end of 25 days), and faster and stronger interfacial polarization were achieved in purified and following lyophilized sepiolite dispersion with 10 wt% particle concentration, while the mechanical grinding process caused adverse effects on the ER response, dispersion stability, and dielectric properties of sepiolite dispersion. Such basic physical approaches can be considered to achieve improved ER performance in future studies on 1D nanostructure-based ER fluids.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"446 ","pages":"Article 129297"},"PeriodicalIF":5.2,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146035963","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}

In this work, we investigated the structural properties and LC organization of Ln(III) complexes with substituted β-diketones and Lewis bases using density functional theory, machine learning models, and molecular dynamics simulations. Ten Ln(III) complexes with several ions (La, Nd, Sm, Eu, Gd, Tb, Ho, Er, Yb, Lu) were simulated to study correlations between their structural properties and LC behavior. For the first time, machine learning models were employed to enhance molecular dynamics simulations of LC Ln(III) complexes, and the computational results were compared with experimental data. This complex approach demonstrates that the ionic radius of Ln(III) primarily controls the thermodynamic parameters and temperatures of phase transitions, whereas the ligand environment and geometric anisotropy determine the emergence of LC properties. Additionally, the Voronoi-Dirichlet polyhedral approach was applied to analyze the first coordination sphere and intermolecular interaction forces. The volumes and radii of these polyhedra were found to correlate with LC phase transition parameters. The developed computational protocol provides a robust predictive tool for the multiscale simulation of complex structures and polyatomic systems for materials science, the rational design and discovery of novel lanthanide-based functional materials with controlled supramolecular organization, the next-generation luminescent materials for displays, sensors, lasers and other optoelectronic devices.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"446 ","pages":"Article 129239"},"PeriodicalIF":5.2,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145950417","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}

The HDES prepared in this work were based on DL-menthol (MENT) as the hydrogen bond acceptor (HBA), combined with various carboxylic acids as hydrogen bond donors (HBDs), including acetic acid (AcA), decanoic acid (DCA), and dodecanoic acid (DDCA). Fourier Transform Infrared Spectroscopy analysis (FTIR) confirmed the formation of eutectic mixtures through characteristic shifts and broadening of O<img>H and C<img>O bands, as well as the disruption of carboxylic acid dimers. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TG/DTG) revealed that most mixtures formed eutectic systems with melting points lower than those of their individual components. However, the thermal behavior was complex, often exhibiting multiple crystallization or melting peaks. It suggests the formation of off-composition mixtures, polymorphic structures, or stable supercooled liquids depending on the specific molar ratio. After two years, the MENT: DCA and MENT: DDCA mixtures remained stable, with no significant changes observed in their FTIR spectra. In contrast, the MENT: AcA mixture exhibited significant spectral changes, indicating a weakening of intermolecular interactions. Evolved gas analysis (EGA) validated this by identifying the formation of menthyl acetate, indicating a slow esterification reaction over time.
