Summary: The discovery of new non-toxic metal complexes with biological activity is an active area of research. Two Cu+2 complexes with new ligands were synthesized and characterized by X-ray crystallography. Both complexes showed in vitro biological activities, with complex C2 being more active. The complexes exhibited distorted square pyramidal square-planar geometries and were characterized by FT-IR and UV-Vis spectroscopy. The antibacterial activity of the complexes against four Gram-positive and two Gram-negative bacteria was determined using the microdilution method, and cytotoxicity studies were carried out on tumor cell lines and a normal cell line. Flow cytometric assessment of apoptosis induced by the complexes was also performed.

Summary: Tellurium nanoneedles were synthesized as a new antibacterial candidate with both chemical and physical effects on bacteria. They had strong affinity to bacterial cell membranes and promoted the generation of reactive oxygen species (ROS), resulting in excellent antibacterial effects against Staphylococcus aureus and Escherichia coli. The needle-like morphology also physically damaged bacterial cell membranes, while being inert and biocompatible in mammalian cells. In addition, the antibacterial activity was maintained even after long-term dispersion in a phosphate buffered saline solution.

Summary: Complexes of the immunosuppressive drug azathioprine with various metal ions were synthesized and characterized through spectroscopic and thermal studies. The coordination of azathioprine to the metal ions was confirmed by infrared spectroscopy, while the absence of changes in a specific range suggested that the ether group may not be involved in the binding. Thermal analysis showed that the complexes decomposed in multiple steps, leading to the formation of metal oxides.

Summary: This research reports the formation of a new adsorbent, activated bentonite with cinnamic acid, which demonstrates high efficiency in removing dyes from wastewater. The study compares the adsorption efficiency of the activated bentonite with unmodified bentonite using methyl orange and rhodamine-B as target dyes. Characterization techniques such as XRD, FTIR, and SEM were employed to analyze the activated bentonite. The results suggest that acid activation with cinnamic acid increases the surface area of the bentonite, enhancing its adsorption efficiency.

Summary: Eight polymer-metal complexes were synthesized through complexation of divalent Mn(II), Ni(II), Co(II), and Cu(II) metal ions with modified polystyrene-alt-(maleic anhydride) (PSMAP and PSMAM) ligands. The structures of the complexes were characterized using magnetic moment susceptibility, conductance measurements, FT-IR spectroscopy, UV-VIS, TGA, and SEM. The complexes exhibited non-electrolytic behavior based on conductance measurements, and the polymer ligands acted as neutral bidentate NO ligands. The complexes showed octahedral geometry based on their electronic spectra and magnetic properties, and were more thermally stable than the ligands. SEM and TEM provided information on the surface structure and particle size of the complexes.

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.

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.
