“…This indicates that the coated GCN and H-GCN plates have a minimum corrosion rate (1.284 and 0.199 mm/year) than the untreated MS plate (3.215 mm/year). Thus, the above experimental observation con rmed that the hydrothermally exfoliated GCN over the MS plate and GCN showed they improve corrosion resistance in an aqueous NaCl electrolyte [23]. Therefore, hydrothermally exfoliated GCN showed a very minimal corrosion rate and strong electrochemical corrosion resistance (H-GCN) against GCN and MS plates.…”

This article outlines the preparation and exfoliation of graphitic-carbon nitride (GCN) by thermal polymerization technique using urea proceeded by the hydrothermal approach for the application of corrosion resistance in radiators. The prepared sample was characterized by using various methods. X-ray powder diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR) confirmed the purity of GCN, and surface morphology results revealed the formation of spherical-shaped GCN. Herein, graphitic carbon nitride (GCN) was synthesized to enhance its corrosion-resistance performance on mild steel (MS) under a seawater atmosphere. The corrosion behavior of the graphitic-carbon nitride (GCN) synthesized by the hydrothermal method was examined by conducting electrochemical corrosion tests in a 3.5% NaCl medium under three different temperatures. The excellent temperature dependant electro-catalytic activity of the prepared GCN was analyzed. The hydrothermal exfoliation process highly enhances the structural, optical, and electrochemical properties like corrosion resistance and stability of the prepared GCN. This study demonstrates that hydrothermally exfoliated GCN exhibits low corrosion rates and high electrochemical corrosion resistance, which could be a potential candidate for corrosion inhibitors in radiators.

Due to their enhanced antibacterial activity and minimal cytotoxicity, nanocomposite hydrogels have been considered attractive materials for biomedical applications. Maleic acid was used as a crosslinker in the development of methylcellulose/PVP/ZnO nanocomposite hydrogels. FESEM, FTIR, EDX, hemolytic and antioxidant tests were carried out to evaluate the prepared nanocomposites. FESEM and EDX measurements confirmed the presence of ZnO nanoparticles in the polymer matrix. The DLS revealed testing that the particle's maximum diameter is 50.7 nm, confirming the particle size and stability of the biogenic ZnO NPs. ZnO NPs incorporated nanocomposites exhibited excellent biodegradability and enhanced antioxidant activity. MC/PVP/ZnO nanocomposites exhibited a significant zone of inhibition against E. coli and S. aureus bacteria. The results showed that the prepared nanocomposites have high porosity (>80%), swelling properties, and antioxidant activity (>35%). The hemolytic activity test demonstrates that the developed nanocomposites are nontoxic. These findings significantly support the use of these innovative MC/PVP/ZnO bio-nanocomposite dressings for wound healing applications.
