Summary: Surfactants are widely used in various industries such as household cleaning, personal care, and cosmetics. However, most of the surfactants currently in use are derived from fossil fuels and are environmentally unfriendly and toxic. Therefore, there is a need for greener alternatives. The determination of the critical micelle concentration of surfactants is crucial for their development as analytical tools and commercial materials. A fast and cost-effective method using dried drop coffee ring image analysis is proposed for determining the surfactant critical micelle concentration.

Summary: The study investigated the binding of ferulic acid (FA) with sodium deoxycholate (NaDC) using fluorescence and absorption measurements. The presence of FA was found to favor the micellization of NaDC, leading to changes in absorption and fluorescence spectra as NaDC molecules transition from monomers to primary and secondary micelles. The interaction between FA and NaDC involved hydrophobic binding, hydrogen bonding, and unique structural characteristics of bile salt.

Summary: The efficacy of drugs is often challenged by issues such as premature degradation, low solubility, side effects, and rapid clearance from the circulatory system. Surfactants play a pivotal role in solubilizing a wide variety of drug molecules through micellization in physiologically relevant fluids. They offer advantages over conventional liposomes and phospholipid-based formulations, including higher micellar stability, ease of formation, and lower maintenance expenses. This review critically analyzes the interactions between loaded drugs and surfactants in micellar delivery systems, highlighting the need for a better understanding of these interactions.

Summary: By utilizing a micelle-like structure with a hydrophobic outer layer to protect ionic interactions, the ionically crosslinked elastomers are able to maintain self-healing and long-term stability in aqueous, acidic, and basic environments. These elastomers exhibit superior tensile strength and strain at break compared to existing waterproof self-healing elastomers, making them suitable for applications such as strain sensors and dielectric actuators in harsh environments. This design strategy of hydrophobic protection for dynamic interactions can be extended to other self-healing materials.

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.
