    Adsorption study of N (-benzo[d]thiazol-2-yl)-1-(thiophene-2-yl) methanimine at mild steel/aqueous H2SO4 interface
    (Elsevier, 2022) Singh, Ashish Kumar; Singh, Manjeet; Thakur, Sanjeeve; Pani, Balaram; Kaya, Savas; EL Ibrahimi, Brahim; Marzouki, Riadh
    This study reports microwave (MW) assisted synthesis of N (-benzo[d]thiazol-2-yl)-1-(thiophene-2-yl) methanimine (BTTM) in reasonably good yield and purity. The synthesized compound (BTTM) has been characterized by elemental analysis, IR and 1H NMR spectroscopy and examined for its corrosion inhibition activity for mild steel in aqueous H2SO4 medium using gravimetric and different electrochemical methods. The corrosion inhibition study was also performed at different temperatures to understand the effect of temperature on corrosion inhibiting potential of BTTM. The metal protecting ability of BTTM in acid solution was further examined by surface analyses; X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and contact angle measurement. The surface analyses reveal that the BTTM adsorbed on mild steel (MS) surface following ElAwady isotherm. Theoretical studies, viz. molecular orbital analysis and molecular dynamic (MD) modelling were also conducted to understand the inhibition mechanism completely.

    Advancement of corrosion inhibitor system through N-heterocyclic compounds: a review
    (Taylor & Francis Ltd, 2023) Sheetal, Rashika; Batra, Rashika; Singh, Ashish Kumar; Singh, Manjeet; Thakur, Sanjeeve; Pani, Balaram; Kaya, Savas
    Organic compounds containing heteroatoms have been comprehended to exhibit a remarkable tendency towards corrosion mitigation. This corrosion mitigating tendency is enabled by the presence of electron clouds composed of lone pairs, pi-electrons, which allow them to be adsorbed over metallic equivalents. Because of the availability of nitrogen as heteroatoms, these compounds are being extensively used for corrosion diminution. This article looks at a variety of heterocyclic organic compounds like imidazole, triazole, pyridine, pyrazole, quinoline, tetrazole, pyrimidine, purine and pyrrole, having nitrogen as their prime constituent heteroatom for their anti-corrosive properties. The anti-corrosive properties of these nitrogen-based compounds in acidic conditions have been demonstrated using all available experimental techniques such as EIS, PDP and other theoretical investigations such as DFT and MD. Furthermore, the shift in the trend of these compounds inhibitory efficiencies has been noted and underlined here.
