Summary: Pyrolysis temperature has a significant impact on the properties of biochar, which in turn affects the adsorption of heavy metal ions. Comparing biochars from the pyrolysis of maize straw and wheat straw, it was found that the biochar produced at 400 degrees C from maize straw showed the best physical and chemical properties, as well as a higher adsorption rate and capacity. The adsorption mechanisms involve surface precipitation of carbonates and phosphates, as well as complexation with oxygenated functional groups and delocalized pi electrons.

Summary: The main sources of heavy metal pollution are industrial wastewater and waste residues, which have serious detrimental effects on water and soil environments as well as human health. In this study, a gel adsorbent (AA-SW-AMPS) was prepared using microwave-assisted chemical cross-linking with fir sawdust as the raw material, following the principle of waste utilization. The microstructure, reaction mechanism, and water absorption performance of AA-SW-AMPS were investigated using SEM, FTIR, XRD, and swelling dynamic experiments. The results showed that AA-SW-AMPS had a porous structure with a specific surface area of 240.75 cm²/g, enabling excellent sorption of heavy metals.

Summary: The galvanic reaction between graphene quantum dot (GQD)-stabilized silver nanoparticles (AgNP)-modified glassy carbon (GC) surface and Hg(II) leads to the complete dissolution of AgNPs within 15 minutes and the subsequent growth of Hg(0) as a flower on the GQD surface. This unique anti-amalgamation reaction is caused by direct deposition of Hg(0) by available oxygen functional groups and strong adsorption on the GQD graphene surface, followed by subsequent growth of Hg(0) as a flower due to the galvanic reaction between AgNPs and Hg(II).

Summary: Carbon porous materials obtained through KOH activation were found to be effective adsorbents for the removal of methylene blue (MB) from dye-containing wastewater. The pore size distribution of the materials played a crucial role in the adsorption of MB, and materials with an average pore diameter of 3.5 nm showed high MB adsorption capacity. Mathematical processing of experimental data using kinetic and diffusion models as well as adsorption equilibrium isotherm models provided comprehensive understanding of the adsorption mechanisms. The results of this study suggest that the porous carbon materials have great potential for the treatment of dye-containing wastewater.

Summary: In this study, cellulose nanowhiskers (CNW)/chitosan nanocomposite films were synthesized using deep eutectic solvents (DES) to change the chemical structures. The incorporation of CNW into chitosan films resulted in sharper and stronger peaks, as well as an infusion of more amide elements. The mechanical properties of the nanocomposite films, including tensile strength (TS), Young's modulus (YM), and elongation at break, were enhanced with CNW filler, although YM and TS decreased due to the hygroscopic nature of the films. DES, as a green solvent, has the potential to replace ionic liquids in materials synthesis while reducing the environmental impact of chemical production.

Summary: Water is a major source of human diseases due to contamination with bacteria and other pathogenic microorganisms. This review focuses on microbial hazards in water and wastewater, and the use of sonochemical reactors (SCRs) combined with advanced oxidation processes (AOPs) for disinfection. Various types of cavitation reactors, including acoustic cavitation reactors (ACRs) and hydrodynamic cavitation reactors (HCRs), have been employed for the treatment of contaminated waters. Bacterial degradation is primarily caused by thinning of microbial membranes, local warming, and free radical generation due to cavitation. The mechanisms and effects of cavitation in the disinfection process are still poorly understood.

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 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.
