Plant extracts used as corrosion inhibitor for mild steel usually degrade as the temperature increases above room temperature. In this study, we used (cashew leaf) extract to synthesize silver nanoparticles for improving mild steel's inhibition stability under salinized conditions. Cashew leaves were used as a reducing agent to synthesise silver nanoparticles.

MnO/ZnO-AlO-CeO catalyst was synthesized through a solid-state process from a 3% Mn-doped Zn-(Al/Ce) layered double hydroxide structure. Detailed structural and optical characterization using XRD, FTIR, UV-visible DRS, and TEM was conducted. By investigating clofibric acid (CA) degradation in aqueous solution, MnO/ZnO-AlO-CeO photocatalytic activity was evaluated.

Graphene-based materials have been widely studied in the field of supercapacitors. However, their electrochemical properties and applications are still restricted by the susceptibility of graphene-based materials to curling and agglomeration during production. This study introduces a facile method for synthesizing reduced graphene oxide (rGO) nanosheets and activated carbon based on olive stones (OS) with polyaniline (PAni) surface decoration for the development of supercapacitors.

Article Synopsis
  • Almond shell-based biocarbon is an effective and inexpensive adsorbent for removing malachite green dye, characterized using FT-IR, DRX, and BET techniques, revealing a surface area of 120.21 m²/g.
  • The adsorption studies indicate that the process fits the Langmuir isotherm and pseudo-second-order kinetic model, achieving a maximum capacity of 166.66 mg/g at specific conditions (adsorbent mass of 0.1 g, dye concentration of 600 mg/L, and temperature of 25 °C).
  • The positive ∆H value (12.19 J/mol) indicates that the adsorption process is endothermic, and the D-opt
