Summary: This study proposes a strategy to directly fuse the functional attributes of small additives into supramolecular polyelectrolyte nanoporous membranes under ambient conditions. The pore size distributions and mechanical properties of the membranes are controlled by tuning the hydrogen bonding interactions between the additives and the polyelectrolyte. The study demonstrates that small dye additives/homo-poly(ionic liquid) solutions can be used as versatile inks to create colorful light emitting films with robust underwater adhesion strength, excellent stretchability, and flexibility on various surfaces.

Summary: This study investigates the effect of C2 methylation on the cohesive interaction of trifluoromethanesulfonate ionic liquids (ILs). The nature of the anion strongly influences the impact of C2 methylation. Strong-coordinating and smaller anions promote hydrogen bonding with the acidic hydrogen at the C2 position, while weak-coordinating and larger anions result in a dominant decrease in liquid entropy due to C2 methylation.

Summary: Poly(oxymethylene) dimethyl ethers (OME) are synthetic fuels with better combustion properties than fossil diesel fuel and can be obtained from renewable resources. However, OME + HVO mixtures split into two liquid phases due to the uptake of small amounts of water, which is unacceptable for use as fuels. Experimental studies were conducted on ternary model systems to investigate the phase behavior, and correlation with UNIFAC was achieved. The results confirm that water uptake causes the phase split and measures to overcome this problem are discussed.

Summary: The electropositivity of carbon atom in CO2 allows it to act as a proton acceptor or electron acceptor in Lewis acid-base interactions with organic chemicals. High-pressure CO2/alcohol solvent systems are vital for supercritical extraction, dehydration of alcohols, and extraction of natural products. Understanding the Lewis acid-base interactions between CO2 and alcohols is crucial for the solvation process under high-pressure conditions and the development of thermodynamic models.

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.
