Summary: The increasing energy consumption has led to a rise in sulfur emissions, causing economic and health issues, as well as impacting the efficiency of diesel engine emission control systems. To combat this, research is being conducted on various desulfurization technologies, including conventional methods like hydrodesulfurization and alternative processes such as adsorptive, extractive, oxidative, and bio-desulfurization. Factors such as DES selection, extraction temperature, extraction time, DES regeneration, and multistage extractions play a crucial role in the desulfurization efficiency, with deep eutectic solvents showing promise as a less toxic and more efficient alternative for extractive desulfurization.

Summary: A new concept of green solvents called superlong supercooling solvents (SSSs) is proposed, which are metastable liquid solvents that can be used at temperatures around or slightly higher than room temperature before condensing after a superlong time. SSSs can serve as green alternatives to water, supercritical fluids, ionic liquids, and deep eutectic solvents (DESs).

Summary: In this study, a fast, cheap, and eco-friendly method for amine group protection was developed. It involves the formation of amide bonds using choline chloride as a hydrogen bond acceptor and the starting amine as a hydrogen bond donor through the generation of in situ amine-based deep eutectic solvents. This novel approach avoids the use of toxic solvents, making it a sustainable alternative to classic amine protection procedures.

Summary: The study explores the properties of concentrated ionic fluids and distinguishes them from concentrated aqueous brines. It demonstrates a continuous relationship between molar conductivity and fluidity, regardless of cation, charge density, or ionic radius. The diffusion coefficients of specific metal chlorides in various ionic fluids show a linear correlation with fluidity. By adjusting chloride and water activity, selective etching of mixed metal waste streams can be achieved.

Summary: Low toxicity is a crucial property for the sustainable use of polyethylene glycol-based deep eutectic solvents (PEG-based DESs) in various fields. However, the specific toxicity of PEG-based DESs has not been reported, and guidelines for reducing toxicity need to be explored. This study evaluated the cytotoxicity of several PEG-based DESs against lung cancer cells (A549) and proposed strategies for minimizing toxicity, such as adjusting mole ratio, hydrogen-bonding donor, hydrogen-bonding acceptor, components numbers, and solvent concentration. The results showed that DESs are more toxic than their individual components, generally following the toxicity order of the individual components, except for the hydrogen-bonding donor. This research offers potential approaches for reducing the toxicity of DESs in sustainable and green chemistry.

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.
