“…The azole family, including thiazoles, triazoles and imidazole, has been proposed as corrosion inhibitors for copper, but has been scarcely explored to inhibit steel corrosion. Interestingly, imidazole can be loaded into Y 2 O 3 and used as anti-corrosive pigments in protective epoxy coatings exposed to aggressive environment [ 25 , 26 ]. Thus, this work aims to investigate the effectiveness of the new anti-corrosive pigment based on yttrium oxide (Y 2 O 3 ) loaded with imidazole as a corrosion inhibitor when incorporated into the epoxy formulation for the coating of steel plates.…”

The search for highly effective corrosion protection solutions to avoid degradation of the metallic parts is enabling the development of polymeric organic coatings. Of particular relevance, polymeric nanocomposite coatings, modified with corrosion inhibitors, have been developed to provide enhanced surface protection. In this work, yttrium oxide nanoparticles loaded with corrosion inhibitor (Imidazole), used as additives in the formulation of epoxy for coated on the steel substrate. The loading of Y2O3 with imidazole was confirmed by field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and Brunauer–Emmett–Teller analysis. UV-Vis analysis demonstrated the pH-sensitive behavior of the imidazole that helps in self-release when necessary. Electrochemical impedance spectroscopy (EIS) of the coated samples revealed that the coating modified with Y2O3/IMD provides better corrosion protection compared to coatings containing only Y2O3. XPS analysis validated the presence of an imidazole protective film on the steel substrate that enhanced the corrosion resistance of the coated samples

Molecular dynamics (MD) simulation is a powerful tool to study the molecular level working mechanism of corrosion inhibitors in mitigating corrosion. In the past decades, MD simulation has emerged as an instrument to investigate the interactions at the interface between the inhibitor molecule and the metal surface. Combined with experimental measurement, theoretical examination from MD simulation delivers useful information on the adsorption ability and orientation of the molecule on the surface. It relates the microscopic characteristics to the macroscopic properties which enables researchers to develop high performance inhibitors. Although there has been vast growth in the number of studies that use molecular dynamic evaluation, there is still lack of comprehensive review specifically for corrosion inhibition of organic inhibitors on ferrous metal in acidic solution. Much uncertainty still exists on the approaches and steps in performing MD simulation for corrosion system. This paper reviews the basic principle of MD simulation along with methods, selection of parameters, expected result such as adsorption energy, binding energy and inhibitor orientation, and recent publications in corrosion inhibition studies.

[5][6], antifungal [7][8], anti-inflammatory [9][10], antiviral [11][12], anti-parasitic [13][14], anticancer [10][11][12][13][14][15], antihistamine [16][17]and enzyme inhibition [15][16][17][18]. As demonstrated in Table 1, Imidazole and its derivatives are employed in a variety of medical applications.…”

AZO complexes synthesized by binding metal ions as Mn(II), Co(II), Ni(II) and Cu(II), with the ligand (L) [ethyl 4-((E)-(5-oxo-1-(((1E,2E)-3-phenylallylidene)amino)-2-thioxo-2,5-dihydro-1H-imidazol-4-yl)diazenyl)benzoate] was prepared from three steps ,first step preparation Schiff base product of condensation reaction by reaction Thiosemicarbazide with cinnamaldeyde, second step preparation the Imidazole ring close by reaction ligand 1 with chloroethylacetate, finally preparation Azo ligand(Diazanium compound) by reaction ligand 2 with benzocain. Characterized the ligands and complexes in their solid state using the elemental micro analysis (C.H.N.S), flame atomic absorption. UV-vis spectroscopy, FT-IR, magnetic susceptibility measurements, Mass spectrum, 1H-NMR spectra and electrical molar conductivity. These techniques produced comparable results with those obtained for the solid complexes. From the data of all techniques, octahedral geometry was proposed for Mn(II), Co(II), Ni(II) and Cu(II) complexes.
