Summary: Diffusion dialysis is a promising method for the recovery of titania waste acid due to its low energy consumption and ease of operation. However, the current commercial anion exchange membranes (AEMs) suffer from low acid permeability coefficient and high cost. Therefore, the development of high-performance AEMs is crucial for the successful recovery of titania waste acid.

Summary: N-methyl pyrrolidone (NMP) is a critical solvent for the production of polyaramids, but its reprotoxicity and pending REACH restrictions call for a benign alternative. A mixture of N-butyl pyrrolidone (NBP) and the ionic liquid [C(8)MIm][Cl] is proposed as a promising candidate to replace NMP, offering a green approach to polyaramid synthesis.

Summary: N-Methyl-2-pyrrolidone is a toxic solvent commonly used in the synthesis of polyurethane dispersions, but due to strict regulations on its use, green alternatives are necessary. Dihydrolevoglucosenone and gamma valerolactone have shown comparable performance to NMP as cosolvents in the synthesis and film forming process of PUD.

Summary: Composite polymeric membranes with enhanced anti-fouling properties and antimicrobial activities were prepared using the phase inversion technique with poly (ether-ether-sulfone) (PEES)/polyethylene glycol and n-ZnO. The addition of PEG and n-ZnO increased the surface hydrophilicity and anti-fouling properties of the membranes, leading to improved permeate flux and antibacterial capabilities. The fabricated membrane also showed significant rejection of metal ions and proteins, making it suitable for water purification.

Summary: By changing the preparation and pretreatment conditions, the properties of Nafion membranes can be optimized. In this study, a Nafion-NMP membrane with higher conductivity and comparable hydrogen permeability was obtained by casting from a Nafion dispersion in N-methyl-2-pyrrolidone. The increase in conductivity is attributed to the optimization of the Nafion-NMP microstructure, which improves the connectivity of the pores and channels system. This leads to an increased capacity of the membrane electrode assembly compared to a commercial Nafion (R) 212 membrane.

Summary: This study investigates the biodegradation of N-methyl pyrrolidone (NMP) in activated sludge and identifies the factors that enhance its degradation. It finds that prolonged acclimation of biomass with NMP improves NMP biodegradation, and specific bacteria isolated from the acclimated biomass can significantly accelerate NMP degradation in activated sludge. Additionally, the study identifies monomethylamine as a key intermediate that limits the mineralization of NMP and demonstrates that enhancing its removal can expedite NMP biodegradation.

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.

This study examined the influence of SBS content and molecular structure on viscosity and compatibility. The results showed that the viscosity contribution of SBS is determined by its molecular structure and phase morphology.

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.
