Summary: Interfacial tension (IFT) and wettability are important factors in determining oil/water distributions and hydrocarbon production in reservoirs. This study investigates the effects of ionic liquids (ILs) on IFT and wettability in sandstone reservoirs. The results show that ILs can lower alkane-water IFT and influence the interaction between oil droplets and the quartz surface. Molecular dynamic simulations indicate that ILs can reduce the interaction energy between octane droplets and the quartz surface. These findings have promising applications in enhanced oil recovery and oil contamination removal.

Summary: The proton activity at the electrified interface plays a crucial role in the kinetics of proton-coupled electron transfer reactions. By using a library of protic ionic liquids on platinum and gold interfaces, researchers have successfully enhanced the oxygen reduction reaction activity by up to fivefold, showing a volcano-shaped dependence on the pK(a) of the ionic liquid. This enhancement is attributed to strengthened hydrogen bonds between ORR products and ionic liquids with similar pK(a)s, leading to favorable PCET kinetics.

Summary: In this study, the extract of the Passiflora plant was used as a natural surfactant for enhanced oil recovery. The optimal critical micelle concentration (CMC) was found to be 4 wt%, which resulted in a minimum interfacial tension (IFT) of 13 mN/m and a contact angle (CA) of 55 degrees on the surface of the carbonate rock. The surfactant solution enabled an additional 7.5% original oil in place (OOIP) to be extracted from the rock plug.

Summary: By utilizing STM breaking junction and shell-isolated nanoparticle-enhanced Raman spectroscopy, researchers investigated the electron transport and adsorption geometries of 4,4'-bipyridine on Au(111). The surface modification with ionic liquids containing specific cations was found to influence the adsorption configurations of the molecules and their single-molecule conductance, with water addition resulting in significant changes. The dihedral angle between the adsorbed pyridyl ring and the surface was observed to decrease with increasing surface electronic density, enhancing electron donation from the surface to the pyridyl ring.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: In this study, the selective oxidation of aromatic aldehydes was investigated using Ru(VI) as a catalyst and hexacyanoferrate (III) as a cooxidant in an alkaline medium. The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

Summary: This paper reports on the synthesis, structural characterization, spectral and nonlinear-optical properties of glass nanocomposites made of glass forming ionic liquid crystals and nanoparticles. The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
