“…It has been commonly established that when a peak appears in the RDF graph of a particular atom(s) and the surface between 1 and 3.5 Å, it is a strong indication that chemisorption occurred whereas the presence of physisorption RDF peaks is estimated at greater distances (typically > 3.5 Å) [22,23,25,[31][32][33][34]43].…”

“…The accomplished results from MD and the corresponding RDF analysis validated the well-founded propensity of the inhibitors to adsorb and protect the metal.

“…Figure 4 depicts the HOMO and LUMO OM and ESP of the Pantoprazole medication, and Table 3 lists the most often seen DFT indices. The majority of the HOMO and LUMO densities were localized in the region of the molecule that contained the imidazole moiety.When it comes to Pantoprazole, the HOMO and LUMO were significant due to their ability to interact with the Fe (1 1 0) surface via electron donation and acceptation, respectively[2,7,21,[24][25][26][27][29][30][31]36,[43][44][45].…”

The corrosion behavior of mild steel in a 1 M aqueous sulfuric acid medium in the presence and absence of the drug Pantoprazole was investigated using potentiodynamic polarization and quantum chemical calculations as well as Monte Carlo and molecular dynamic simulations. The potentiodynamic experiments indicated that this molecule, as a result of its adsorption on a mild steel surface, functioned as a mixed inhibitor. The goal of the study was to use theoretical calculations to acquire a better understanding of how inhibition works. The adsorption behavior of the examined compounds on the Fe (1 1 0) surface was calculated using a Monte Carlo simulation. Furthermore, the molecules were studied using density functional theory (DFT), especially the PBE functional, to determine the relationship between the molecular structure and the corrosion inhibition behavior of the chemical under research. The adsorption energies of Pantoprazole (in its three different protonation states) iron were calculated more precisely using molecular mechanics with periodic boundary conditions (PBC). The predicted theoretical parameters were found to be in agreement with the experimental data, which was a considerable help in understanding the corrosion inhibition mechanism displayed by this chemical.

The unique superhydrophobic property of lotus leaf, encouraged researchers to fabricate artificial superhydrophobic surfaces (SHs) adopting different methods. The purpose of this work is to attempt a modest, robust and environmentally safeprocedure to build a superhydrophobic surface on aluminium substrate by wet-chemical grafting. The substrate after few pretreatments like mechanical, chemical etching, anodizing at different current density and at different time duration was immersed in a solution containing sodium hydroxide in deionized water, lauric acid in ethanol. The effect of duration of anodization and sealing on the production of superhydrophobic surface was highlighed. Using Scanning Electron Micrsocopy (SEM) the surface morphology of the bare aluminium substrate and superhydrophobic surface. Using static water contact angle (WCA) measurements the non-wetting property of the as such fabricated superhydrophboic surface was studied and compared with the bare aluminium substrate. The corrosion resistance of the fabricated superhydrophobic surface in 3.5 % NaCl medium was examined by potentiodynamic polarization method and compared with the bare aluminium substrate. The fabricated SHs showsvery good corrosion resistance in comparison with the bare aluminiuim substrate in 3.5 % NaCl medium..
