Globally, researchers have devoted consistent efforts to producing excellent coating properties since plays an essential role in enhancing electrochemical performance and surface quality. In this study, TiO2 nanoparticles varying concentrations of 0.5, 1, 2, 3 wt.% were added into the acrylic-epoxy polymeric matrix with 90:10 (90A:10E) ratio incorporated 1 graphene, fabricate graphene/TiO2 -based nanocomposite systems. Furthermore, composites investigated by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), ultraviolet-visible (UV-Vis) spectroscopy, water contact angle (WCA) measurements, cross-hatch test (CHT), respectively. Moreover, field emission scanning electron microscope (FESEM) impedance (EIS) tests conducted investigate dispersibility anticorrosion mechanism coatings. The EIS was observed determining breakpoint frequencies over a period 90 days. results revealed that successfully decorated on graphene chemical bonds, which resulted coatings exhibiting better within matrix. WCA increased along achieving highest CA 120.85° for TiO2. Excellent dispersion uniform distribution polymer shown up 2 inclusion. Among systems, throughout immersion time, (1:1) system exhibited best high modulus values (Z0.01 Hz), exceeding 1010 Ω cm2.

Zinc has been demonstrated to boost immune response during SAR-CoV-2 infection, where it prevents coronavirus multiplication. Clinical investigations have testified its beneficial effects on respiratory health and deficiency may reduce function. A highly sensitive detection of Zn(II) ion via differential pulse voltammetry (DPV) utilizing an environmentally friendly modified screen-printed carbon electrode (SPCE) electrochemically reduced graphene oxide (ErGO) embedded with carboxylated-8-carboxamidoquinoline (CACQ) as chelating ligand. The green CACQ/ErGO-modified SPCE was characterized by spectroscopy techniques, such Fourier-transform infrared (FTIR) spectroscopy, Raman field-emission scanning electron microscopy energy dispersive X-ray (FESEM-EDX). electrode-solution interface studied electrochemical cyclic (CV) DPV methods. CACQ-modified wrinkled ErGO conferred a large surface-to-volume ratio multiple binding sites resulting in greater opportunity for dative covalent events coordination chemistry, considerably accelerated the transfer rate at surface. sensor quick time (60 s), broad linear range [1 pM-1 μM ion], limit (LOD) 0.53 pM, 35 days storage period (≥80% initial retained), good reproducibility [relative standard deviation (RSD) = 3.4%], repeatability (RSD 4.4%). developed applied determine concentration dietary supplement samples, results were agreement those obtained from inductively coupled plasma-mass spectrometry (ICP-MS).
