“…From this figure, it is observed that the coated steel exhibits a much greater radius of curvature than the uncoated steel, which indicates a noticeable increase in the corrosion resistance. The efficiency of the coating was calculated using Equation (1), where % ef is the coating efficiency, SS and SR the corrosion resistance of the steel and the coated steel, respectively, [ 24 , 25 , 26 , 27 ], finding an increase of 92.91% in the corrosion resistance, as shown in Table 3 .

In this work, the production of a novel methodology for the application of natural corrosion inhibitors on steel, using an autoclave is presented. Tests were carried out using Artemisia vulgaris. The inhibitor was produced with a simple soxhlet extraction process using 15 g of Artemisia vulgaris and 260 mL of Ether. Once the inhibitor was produced, the steel was immersed in it, to form a coating that protects the material against corrosion. Thermogravimetry analyzes (TGA) were performed on the inhibitor, to determine the degradation temperature; it was observed that, at 321 °C, the loss of organic mass begins. After applying the inhibitor to the steel, the Fourier Transform Infrared Spectroscopy (FTIR) technique was used to determine the vibrational bands and the difference between the spectra for the steels before and after the coating was applied. For the evaluation of the method efficiency, Electrochemical Impedance Spectroscopy (EIS) and polarization resistance tests were performed, where Nyquist diagrams and Tafel curves were obtained, for steels with and without treatment. In this case, an increase of 93% in the corrosion resistance, and an 88% decrease in the corrosion rate were observed, proving that this methodology can be used to protect steel against corrosion and extend the steel’s useful life.

“…Theoretically, another important to characterize the chemical reactivity on an inhibitor is the energy gap (ΔE gap ). Energy gap shows the capability of inhibitor to be an effective corrosion inhibitor or not [ 72 , 73 ]. It was found that when the ΔE gap decreases, the adsorption efficiency between the metal surface and the inhibitors increases, because the energy to remove an electron from the HOMO must be lower [ 17 , 18 , 74 ].…”

The corrosion inhibition performance of Hexa (3-methoxy propan-1,2 diol) cyclotriphosphazene (HMC) on carbon steel in 3% NaCl solution was investigated by weight loss (WL), potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS) measurements, Density functional theory (DFT) and Monte Carlo (MC) simulation. The corrosion inhibition efficiency at optimum concentration (10−3M) is 99% of HMC at 298 K. The corrosion inhibition efficiency at 10−3 M decreases with increase in temperature. The adsorption of HMC on the surface of carbon steel obeyed Langmuir isotherm. Potentiodynamic polarization study confirmed that inhibitor anodic-type. DFT and Monte Carlo (MC) simulations based computational approaches were under taken to support the experimental findings. DFT studies revealed that HMC interact with metallic surface through donor-acceptor interactions in which the anionic parts act as electron donor (HOMO) and cationic parts behaved as electron acceptor (LUMO). The MC simulations study showed that studied HMC adsorb spontaneously on Fe (110) surface.

“…The higher the band gap energy, the more UV light is absorbed. The band gap energy of QC was 3.98 eV, corresponding to the wavelength of 311 nm (Afia et al, 2016). Since the photon energies of UV-A and UV-B are 3.10-3.94 eV and 3.94-4.43 eV, respectively (Afia et al, 2016), QC could possibly absorb both UV-A and UV-B.…”

Article InfoA novel, bifunctional nanocomposite methylcellulose (MC) film was developed with antioxidant and ultraviolet (UV)-shielding properties. Quercetin (QC) nanoparticles (NPs) with an average size of approximately 60 nm were generated using a rapid expansion process. Quantification of the total phenolic content (TPC) was performed, followed by three assays-2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, 2,2'-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical cation decolorization and ferric reducing antioxidant power (FRAP)-to investigate the antioxidant effectiveness of the QC-NPs. The QC-NPs had a TPC value of 1,619.59 μg gallic acid equivalents/ mg and high antioxidant activities. The QC-impregnated MC films with all treatments (impregnated with ethanol (QC-EtOH)-, nanoparticles (QC-NPs) or water (QC-H 2 O-MC) with concentrations of 0.1-0.5% w/w) were fabricated using the solution casting technique and characterized. The addition of QC into the MC films was substantiated using Fourier transform infrared spectroscopy. Impregnation of the QC-NPs into the MC film demonstrated that the QC-NPs augmented the antioxidant activities of QC and substantially improved the UV-shielding property of the MC film.
