Summary: A series of new Gemini surfactants were synthesized and characterized, showing good interfacial activity and low CMC values, promising for oil recovery in low permeability reservoirs. Varying the carbon number of the hydrophobic chain can control the surface activity and viscoelastic properties, helping to increase the oil-water interfacial tension and enhance oil recovery efficiency in reservoirs.

Summary: This study systematically explores the influence of alkylbenzene sulfonate Gemini surfactants on the interfacial properties of dodecane/water systems using a dissipative particle dynamics simulation. It is found that increasing the hydrophobic chain length and spacer length can decrease the critical micelle concentration, induce nano-mixing phenomenon, and transform the system from a lamellar interface state to a micelle state.

Summary: This study establishes a combinatorial library composed of 150 molecular weight-defined gemini amphiphiles (GAs) to identify carriers that facilitate robust cytosolic delivery of proteins. The top candidate efficiently translocates a broad spectrum of proteins into the cytosol, primarily through lipid raft-dependent membrane fusion, bypassing the classical endocytic pathway. This study reveals a GA-based small-molecule carrier platform for the direct cytosolic delivery of various types of proteins for therapeutic purposes.

Summary: This study investigates the growth process of lanthanum carbonate nanorods in W/O microemulsions. The initial nucleation dominant growth period forms spherical droplets, which then deviate from spherical shape and evolve into nanorods. The presence of a double bond in the surfactant molecules is responsible for the anisotropic growth. The low water content in the microemulsion inhibits the growth rate of the nanoparticles.

Summary: The clouding development and association of surfactant and antidiabetic drug mixture were studied using different hydrotropes in aqueous solutions. The addition of hydrotropes reduced the cloud point of the surfactant and antidiabetic drug mixture. The critical micelle concentration and extent of ionization of the surfactant and antidiabetic drug mixture were found to be dependent on the hydrotrope contents and temperature changes.

Summary: This study investigates the supramolecular interaction between the surfactant TTAB and the antidiabetic drug MNH in the presence of additives. The critical micelle concentration (CMC) of the mixed system is assessed through conductometric analysis, and the thermodynamic nature of the micellisation process is evaluated by monitoring the effect of temperature change. The estimation of thermodynamic parameters and the determination of the degree of counter ion binding provide insights into the viability of the micellisation process. The study suggests that various supramolecular forces contribute to the aggregation of the TTAB+ MNH system.

Summary: In this study, SmF3 nanoparticles with a hexagonal closed pack structure were synthesized using W/O microemulsions. The crystal structure, composition, purity, and morphology of the nanoparticles were assessed using various techniques. The particle size distribution of the SmF3 nanoparticles was found to be dependent on the water to surfactant mole ratio (W0), with higher W0 resulting in larger particle size distribution. The nanoparticles showed the ability to adsorb phosphate ions from aqueous solution, with smaller nanoparticles exhibiting higher adsorption effectiveness due to their larger surface area.

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.

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.
