Summary: A reusable fixed-state thin film photocatalyst has been developed, exhibiting excellent photocatalytic activity and the ability to effectively eliminate bacteria. The high electron transfer rate of NaTaO3, combined with the surface plasmon resonance behavior of AgNPs, enhances the photocatalytic activity of the AgNPs-NaTaO3 film. The thin film can degrade 82.5% of methylene blue within 50 minutes and has a 1.33-fold improvement in photocatalytic activity compared to pure NaTaO3. In addition, it can almost completely eradicate Staphylococcus aureus and Escherichia coli through the generation of reactive oxygen species and synergistic release of Ag+.

Summary: In this study, the author suggests doping commercial titanium oxide nanoparticles with graphene and silver nanoparticles to enhance their properties. Structural results show that the diffraction angles change as the crystal size increases after doping. Morphological results demonstrate the presence of nanostructures like clusters of spherical nanoparticles. Incorporation of graphene and silver nanoparticles into the matrix leads to increased absorption and decreased energy gap. The inhibitory action results indicate significant inhibition of Staphylococcus aureus growth and slight inhibition of Escherichia coli growth, attributed to the sample's charge and its effect on attractive and repulsive forces. This work represents a promising advancement in improving metal oxide properties.

Summary: The present study aims to prepare novel quinoa biosorbent (QB), acid activated QB (QB/Acid), and its nanocomposite with magnetic nanoparticles (QB/MNPs) for batch scale Cr removal from contaminated water. The Cr adsorption capacity of QB, QB/Acid, and QB/MNPs was evaluated under different conditions. QB/MNPs exhibited the highest Cr adsorption capacity, and the kinetics data best fitted the pseudo-second order model. QB/MNPs showed excellent reusability with minimal leaching of Fe. The comparison with QB/Acid demonstrated the better potential of QB/MNPs for Cr sequestration.

Summary: In this research, surface-modified nano zerovalent copper (nZVC) was successfully synthesized using a borohydride reduction method in solvents such as ethanol (ETOH), ethylene glycol (EG), and tween80 (T80). The as-synthesized material was thoroughly characterized for its morphological surface and crystal structural properties, and it was found that EG provided the best synthesis environment for nZVC. The catalytic efficiency of nZVC/EG was investigated, and it was enhanced by the inclusion of peroxymonosulphate (PMS) in the absence of light. The degradation products and pathways of CBZ were determined, and the ecotoxicity analysis of the degradation products was explored.

Summary: This article evaluates the successful application of selected advanced oxidation processes (AOPs) - cavitation and photocatalysis - in wastewater treatment for the degradation of Rhodamine dyes. The study discusses reactor configuration, process parameters, and the effects of oxidants addition (hydrogen peroxide, ozone, persulfates) on degradation effectiveness as well as the degradation mechanisms. The best technologies achieve 100% degradation within 10-30 minutes. Rhodamine B is effectively degraded under highly acidic conditions (pH 2), while Rhodamine 6G requires basic conditions (pH 10). Hydrogen peroxide and ozone are the most effective oxidants. Ecological Structure Activity Relationships (ECOSAR) revealed acute toxicities of the intermediates and byproducts of the Rh dye.

Summary: In this study, nitrogen-doped titanium dioxide (N-TiO2) nanoparticles were prepared using a modified sol-gel method, and their optical, structural, and morphological properties were characterized using state-of-the-art techniques. The results showed that nitrogen doping increased the surface area and decreased the bandgap energy of TiO2 nanoparticles, leading to enhanced photocatalytic activity and hydrogen production. This suggests that the visible/N-TiO2 photocatalytic system has economic viability and environmental sustainability.

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.

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.

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.

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.
