Summary: Areca residue biochar prepared by pyrolysis and modified with NaOH showed improved adsorption properties for eliminating methylene blue from water. The adsorption process followed Langmuir isotherm model and quasi-secondary kinetic model, with higher adsorption capacity compared to the unmodified biochar. The adsorption mechanism involved multiple mechanisms such as electrostatic gravitational force, pore filling, hydrogen bonding, and pi-pi bonding. NaOH modification enhanced the surface properties and functional group structures of the biochar, making it a favorable adsorbent material for methylene blue removal in water.

Summary: This study investigates the effect of surface modifiers on the catalytic properties and degradation efficiency of a polymeric matrix (CuO/PVA) using three different surfactants: cationic (CTAB), anionic (SLS), and non-ionic (T80). The results show that surface modification significantly enhances the degradation ability of the polymeric CuO, with CTAB-assisted CuO exhibiting a 29% higher degradation rate compared to its unmodified counterpart. The surface characteristics of the catalyst, including particle size, band gap, and morphology, also play a crucial role in the degradation process.

Summary: Complex fumed nanooxides SiO2/Al2O3, SiO2/TiO2, and Al2O3 /SiO2/TiO2 were studied and found that the interior and surface contents of alumina in SA and AST are nonmonotonic functions of total Al2O3 content, while the titania in ST and AST is not affected. This is due to the difference in precursor reactivity of Al2Cl6 and SiCl4 vapor compared to TiCl4 and SiCl4 vapor. Additionally, titania tends to form cores while silica forms NPNP shells.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
