Summary: A diatomite-chitosan composite (CS-DE-10%) was prepared through an in-situ selfassembly method for efficient removal of vanadium from wastewater. The composite showed higher removal efficiency compared to diatomite and chitosan alone, attributed to its increased specific surface area and pore volume. The functional groups in the composite also played a role in enhanced removal ability. The adsorption process could be described by the pseudo-second order kinetic model and Freundlich isotherm model, involving physical adsorption, electrostatic interaction, and surface complexation.

Summary: The goal of this study is to use a graphitic carbon nitride (g-C3N4) based composite zinc oxide (ZnO)-barium titanate (BaTiO3) nanoparticles (g-C3N4-ZnO-BaTiO3) prepared from the extract of Olea Europaea leaves as an initiator under ultrasound to treat water containing a tetracycline (TC) antibiotic. The g-C3N4-ZnO-BaTiO3 nanocomposite was analyzed using FTIR, XRD, XPS, SEM, and TEM. Response surface methodology-Box-Behnken design (RSM-BBD) was used to optimize the process parameters. The results showed that g-C3N4-ZnO-BaTiO3 nanocomposite effectively improved the adsorption performance of TC, indicating its potential as an adsorbent for removing antibiotics from water.

Summary: Efficient removal and recovery of thorium from water resources is achieved using magnetically separable Glu@MNPs. The adsorption process follows Langmuir isotherm and pseudo-second-order equation. The high removal efficiency is due to the presence of various functional groups on Glu@MNPs surface. The optimized conditions from the composite design model match well with batch adsorption studies.

Summary: Room temperature ferrimagnetic nanocomposite (alpha-Mn3O4/MnO)@rGO with significant magnetic properties was synthesized by sol-gel method followed by calcination at higher temperature. The formation of phase was confirmed by X-ray diffraction studies, and its morphology was characterized by HR-TEM images. Elemental mapping using HAADF-STEM confirmed the presence of C, O and Mn, which was further supported by FTIR and XPS studies. The nanocomposite exhibited excellent catalytic activity for the degradation of organic dye, methylene blue (MB), through Fenton-type reaction mediated by H2O2, reaching a degradation rate of about 97.6% in 60 minutes at ambient temperature.

Summary: The adsorption properties of ammonia on MXene V2CT2 (T = O, OH and F) monolayer were studied using ab initio calculations. The effects of ammonia concentration and air humidity were particularly focused on. The results showed moderate adsorption strength independent of NH3 coverage, a significant decrease in electronic conductivity, a noticeable reduction in work function, weakened interaction with F-and OH-terminated V2C monolayers, and enhanced stabilization of air humidity on NH3 adsorption. These findings highlight the suitability of vanadium carbide MXene for NH3 gas sensing and capturing at room temperature.

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: This study investigates the effects of different transition metal decorations on B12N12 nanocages on the adsorption properties of nitrosourea drugs using computational methods. The results reveal the presence of weak non-covalent interactions between metals and nanocages, and the interaction between drugs and nanocages plays a significant role in drug adsorption. Compared to free drugs, the adsorption of drugs on nanocages can facilitate electron transfer, reduce energy gaps and chemical hardness, indicating activity at the target site.

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.
