Summary: This study evaluated the efficiency of Malatya clay (MC) in removing Ni(II) ions from aqueous solutions. The optimal conditions for adsorption included an initial Ni(II) ion concentration of 5 mg/L, a contact duration of 360 min, and a pH of 6.27. Surface characteristics of MC were examined using various techniques, revealing its effectiveness in chemical adsorption. Thermodynamic studies showed that the adsorption of Ni(II) on MC is spontaneous and endothermic. MC has demonstrated to be a cost-effective and environmentally-friendly alternative for Ni(II) ion removal, without the need for chemical treatment.

Summary: This article reviews the removal of nickel (Ni2+) ions from wastewater. Adsorption is the most commonly used method, with nanoparticles, bacterial biomass, and activated carbon from agricultural waste being the preferred adsorbents. Bacterial biomass and activated carbon exhibited high efficiency and renewable biomass sources for Ni2+ ion removal. The biosorption capacity of Ni2+ ions by bacterial biomass ranged from 5.7 to 556 mg/g, while activated carbon ranged from 5.8 to 150 mg/g. Nanocomposite adsorbents may have a biosorption capacity of up to 400 mg/g. Selective biomass adsorbents, such as tolerant bacterial cells biomass, are needed for the elimination of nickel ions.

Summary: A kinetic study of glycerol hydrodeoxygenation (HDO) on NiMo2C/Al2O3 and Al2O3 catalysts, prepared by sol-gel technique, was conducted at high glycerol concentration (95wt%) in a batch reactor, from 250 degrees C to 285 degrees C. The catalysts' structural and surface properties were characterized, and it was found that impregnation of alumina with Ni and Mo followed by carburization increased crystallite sizes and reduced total acidity. The reactions followed a zeroth order model and had no diffusion limitation. The main products were propanediols, ethylene glycol, long-chain molecules, as well as methane, ethane, and propane.

Summary: In this study, iterative and non-iterative methods were used to evaluate the performance of adsorption filters for binary mixtures of volatile organic compounds. The non-iterative method accurately predicted the removal efficiency of toluene and limonene mixture, while showing systematic deviation for the toluene and methyl ethyl ketone mixture. The iterative method, which considered lateral interaction between the adsorbates, correctly predicted the breakthrough of the filter for the non-ideal mixture. Comparative modeling confirmed the negligible significance of gas-phase diffusion and the applicability of different mass transfer approximations.

Summary: A simple synthesis method was used to prepare mesoporous alumina nanorods, which exhibited a high adsorption capacity for the anti-cancer medication DOX. The adsorption behavior of DOX on the alumina nanorods was evaluated under different conditions, and the Langmuir adsorption model was found to fit the data well. The adsorption kinetics followed a pseudo-second-order model, and the adsorption process was endothermic and spontaneous. The alumina nanorods also showed good adsorption performance for DOX in real water samples and could be used for wastewater treatment.

Summary: The solidification of AgCo, AgNi, and AgCu nanodroplets in the size range of 2-8 nm was studied using molecular dynamics simulations. Despite the surface segregation of Ag in the bulk solid, the simulations revealed clear differences in the solidification pathways. AgCo and AgNi separate in the liquid phase and solidify close to equilibrium, while AgCu remains in a kinetically trapped state and solidifies in one step. An analytical model was used to rationalize these differences and analyze the size dependence of solidification temperatures.

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.
