Summary: In this study, the development of single and mixed micelles of anionic surfactant (sodium dodecyl sulfate, SDS) and cationic surfactant (cetylpyridinium chloride, CPC) in propranolol hydrochloride (PPH) drug medium was investigated. The critical micelle concentration (CMC) and degree of ionization (g) were determined from conductivity measurements. The study found that a single CMC was achieved for both pure and mixed surfactant micellization. The CMC and g values were influenced by drug concentrations, mole fractions of surfactant mixture, and temperature. The micelle formation was delayed by PPH drug, and the CMC values decreased with increasing temperature. The interactions between the surfactants were found to be synergistic, and hydrophobic interactions were the main type of interaction. The study also revealed the formation of stable mixed micelles and measured various parameters related to the micellar system. The knowledge gained from this analysis could be utilized to improve pharmaceutical formulations and drug delivery carriers.

Summary: The formation of mixed micelle of tetradecyltrimethylammonium bromide (TTAB) and cetyltrimethylammonium bromide (CTAB) mixture in the presence of ceftriaxone sodium trihydrate (CTS) drug at different concentrations was studied. The results showed that the critical micelle concentration (CMC) of the mixed TTAB + CTAB system was between that of pure TTAB and CTAB. At higher mole fraction of CTAB, the CMC of the TTAB + CTAB mixture deviated from the ideal CMC, indicating stronger interaction between TTAB and CTAB.

Summary: A synthesis procedure and aggregation properties of a homologous series of isothiuronium surfactants have been comprehensively characterized in this study. The increase in alkyl tail length from 10 to 16 carbon atoms leads to a decrease in critical micelle concentration and aggregation numbers, while also affecting solubilization capacity and antimicrobial properties. These findings suggest potential applications in the fabrication of soft nanocontainers for hydrophobic guests with biological functionality.

Summary: This study thoroughly examined the interaction of an antidepressant drug and a non-ionic surfactant mixture in different solvents, revealing nonideal behavior and attractive/synergistic interactions between the components. The presence of NaCl in the system increased synergism, while the presence of urea decreased it. Thermodynamic parameters showed that micellization was entropically spontaneous in water systems, with salt increasing spontaneity and urea decreasing it. UV-Visible studies confirmed the interaction between the drug and surfactant in aqueous systems.

Summary: Solvent-free 0-carotene high loaded microcapsules were fabricated using the wet-milling technique and a complex stabilizer composed of OSA-starch and TS. The addition sequence and mass ratio of both stabilizers were found to affect the particle size distribution, micromorphology, redispersibility, and in vitro digestion of the microcapsules. The biopolymer-surfactant complex inhibited the expansion of the microcapsules, and the dents on the capsule surface facilitated moisture infiltration during rehydration. The composition of the wall materials further influenced the bioaccessibility of 0-carotene during simulated digestion.

Summary: The study assessed the potential of nanocomposite membranes (NCMs) made of sodium alginate and embedded with synthesized zeolitic imidazole framework-8 (ZIF-8) as fillers for separating gaseous mixtures generated by methane reforming. ZIF-8 crystals were synthesized through hydrothermal synthesis, with sizes ranging from 50 to 70 nm. NCMs with 15% filler loading (synthesized ZIF-8) outperformed neat polymer membranes in terms of H-2 permeability and selectivity, achieving a purity of up to 95%. However, NCMs did not perform better than neat polymer membranes in separating gas mixtures. The combination of ZIF-8 and sodium alginate as fillers is a new and worth investigating.

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: 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.
