Water Chestnut Stem-Derived Biochar Supported AgNPs/AC-CTS-PVA Composite Gel for Wastewater Treatment and Potent Antibacterial Performance
Abstract: In the present study, green and efficient Ag-NPs functionalized activated carbon/chitosan-polyvinyl alcohol (AgNPs/AC-CTS-PVA) composite gel was successfully synthesized using water chestnut stem-derived biochar for wastewater treatment and antibacterial applications. The composite was characterized by FTIR, XRD, SEM-EDX, and TGA analyses, confirming the successful incorporation of crystalline Ag nanoparticles within the polymeric matrix and improved thermal stability. The material was tested regarding the removal of the dye of methylene blue (MB) …

CFD Analysis of Double Diffusion Rotating Flow in a Cylindrical Annular MHD Braking System with Joules Heating and Dufour Effects
Abstract: The present study has investigated Joules parameter significance on an axisymmetric whirling flow within a cylindrical annulus, specifically focusing on an MHD braking system. The cylindrical annulus braking system is packed lithium lid liquid (Pr = 0.015), aspect ratio = 2, and imposed to an axial heat and magnetic field. In this study, the modified MAC pressure correction method has been used to solve the mixed convection flow with double …

Photochemical Detoxification of Arsenic- and Mercury-Contaminated Soils: Geochemical Mechanisms and Pathways
Abstract: This study evaluates the geochemical aspects of soil detoxification in areas contaminated with arsenic (As) and mercury (Hg), emphasizing sustainable strategies for improving soil health and ensuring safe crop production. The research provides an ecological and toxicological assessment of regional soils and classifies them base on the concentration and mobility of toxic elements. Although the current levels of As and Hg do not yet present a critical risk to agricultural …

Synthesis and Evaluation of MgO-Supported Activated Carbon for Carbon dioxide Capture
Abstract: Carbon dioxide (CO₂) capture has emerged as a critical strategy for mitigating greenhouse gas emissions and addressing global climate change. In this study, a series of MgO-supported activated carbon adsorbents containing 2, 4, 6, 8, and 10 wt% MgO were successfully synthesized using the impregnation method to evaluate their CO₂ adsorption performance. The structural, chemical, and surface properties of the prepared materials were characterized using powder X-ray diffraction (PXRD), Fourier-transform …
