Summary: In this study, the efficiency of carbon quantum dots (CQDs) as photocatalysts is improved by fine-tuning the surface chemistry through selectively substituting surface carbonyl group (C=O) with phenylhydrazine (PH). The modified CQDs-PH show enhanced light absorption and separation of photogenerated electron-hole pairs, leading to boosted generation of reactive oxygen species (ROS) via peroxymonosulfate (PMS) activation. Theoretical calculations demonstrate spatial separation of electrons and holes on CQDs due to the spontaneous surface polarization induced by PH functionalization. This research provides a feasible approach to enhance the photocatalytic activity of CQDs for sustainable water decontamination.

Summary: Molecular modelling and simulation were used to investigate the removal of amoxicillin (AMX) from water using iron nanoparticles (Fe3O4-NPs). The optimal conditions for adsorption were determined. The results showed that AMX molecules have high chemical potential and electrophilicity index, making them reactive. The adsorption of AMX onto Fe3O4-NPs was highly efficient under optimal conditions of pH 3, dosage of 0.5 g/L, AMX concentration of 60 mg/L, and a contact time of 60 min. Langmuir isotherm and pseudo-second-order kinetics provided the best fit to the adsorption data.

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 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.
