Summary: The study found that adding 0.10 g of remediation material HA/WV with a mass ratio of 1:1 to agricultural land surface soil contaminated with 300 mg Pb2+ can achieve a reduction ratio of available Pb in soil by 61.4%. The addition of wood vinegar can increase the reduction ratio of available Pb by at least 14.7% compared to without wood vinegar. The dominant mechanisms responsible for Pb(II) sorption are adsorption interaction and electrostatic attraction between Pb(II) and oxygen-containing functional groups on HA/WV, with wood vinegar further enhancing these interactions.

Summary: Organic ligand-based sustainable composite hybrid material (CMHs) was synthesized for the sensitive and selective adsorption of Lu(III) from waste samples. The adsorption of Lu(III) was influenced by solution pH, with slightly acidic conditions chosen for optimal separation and adsorption. Other metal ions did not interfere with Lu(III) adsorption due to the high affinity of Lu(III) to CMHs. The CMHs exhibited a high adsorption capacity and the adsorbed Lu(III) ions were easily eluted for regeneration.

Summary: This paper proposes a triple broadband metamaterial absorber by using a composite hybrid structure of graphene and gold patch embedded in silica. The absorber achieves polarization-insensitive triple-broadband terahertz absorption by combining the advantages of gold and graphene. Simulation results demonstrate that the absorber exhibits three broadband absorptions for both TE and TM waves, with a total bandwidth exceeding 4.42 THz. The proposed metamaterial absorber is polarization insensitive and maintains a strong absorption efficacy at incident angles of less than 40°.

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.
