Summary: This study investigated the potential interactions between the antibiotic ceftriaxone sodium (CTS) and the surfactant triton X-100 (TX-100) in the presence and absence of various sodium based electrolytes and hydrotropic salts. The results showed that the hydrophilic interaction was significant when sodium salicylate (NaSal) was used, but not significant when sodium benzoate (NaBenz) was used. Thermodynamic variables were calculated to evaluate the nature of the interactions, and the findings may have important implications for pharmaceutical formulations and understanding drug-surfactant interactions.

Summary: In this study, the addition of Triton X-100 was found to enhance laccase production in Shiraia spp. S9 mycelium culture and facilitate the biodegradation of the micropollutant triclosan. The surfactant induced the release of reactive oxygen species, increased membrane permeability, and upregulated laccase-related gene expression, resulting in a 108-fold increase in laccase production. After 2 days of culture, the degradation and adsorption rate of triclosan reached 80.71% and 10.21%, respectively, and triclosan was almost completely removed (99.88%) from the water phase through a combination of biodegradation and cloud point extraction.

Summary: This study evaluates the impact of n-alcohols on the Cloud Point of nonionic surfactant Triton X-114 at variable concentrations. The results show that the presence of lower alcohols improves the Cloud Point temperature, while higher alcohols bring it down, with variations depending on concentration. The stability of micellar accumulation is also discussed using foaming ability and foam stability data. The study demonstrates that the clouding phenomenon of Triton X114 is an exothermic and non-spontaneous process, and the thermodynamic parameters of the clouding process have been assessed.

Summary: All-atom molecular dynamics simulations were used to investigate the structural properties of micelles formed by the non-ionic surfactant Triton X-114. The solubilisation of two nonsteroidal anti-inflammatory drugs (NSAIDs), ibuprofen and indomethacin, was also studied to understand its effect on the micelle structure. The results showed that solubilising drug molecules caused the micelle shape to become elongated and the drug molecules took orientations within the core of the micelle to remain hydrated. The aggregation of indomethacin led to destabilisation of the micelle, while the ibuprofen-loaded micelle remained stable.

Summary: The cloud point measurement and UV-visible spectroscopic techniques were used to investigate the phase separation, assembly formation, and thermodynamic properties of the Triton X-100 (TX-100) + promethazine hydrochloride (PMH) drug mixed system. The impact of monohydroxy alcohols on the clouding development of the TX-100 + drug mixed system was also demonstrated. The critical micelle concentration of the TX-100 + PMH mixture increased with temperature. The obtained free energy values revealed the non-spontaneity of clouding and spontaneous aggregation of the TX-100 + PMH mixture. The micellization of the TX-100 + PMH mixed system was accompanied by hydrophobic interaction.

Summary: This study reports the effect of adenosine and temperature on the micellization of a cationic gemini surfactant. The results show that the addition of adenosine increases the critical micelle concentration (CMC), and increasing temperature also leads to an increase in CMC. The evaluated energetics indicate lower stability of the surfactant solution in the presence of adenosine. Further analysis confirms that there is no chemical reaction during the interaction between the gemini surfactant and adenosine.

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.
