Experimental, theoretical modeling and optimization of inhibition efficiency of pigeon pea leaf extract as anti-corrosion agent of mild steel in acid environment

Optimization of chicken nail extracts as corrosion inhibitor on mild steel in 2M H2SO4

“…This concern has led to new initiate with the aim of reducing the impact of corrosion. Although, Manikandan et al., 2015, Anadebe et al. (2019) and Stefania et al.…”

“…The corrosion inhibitory effects of various plant extracts had been reported with promising inhibitory efficiency. Some of these plants are: Katemfe (Olawale et al, 2018a, Olawale et al, 2018b); Cashew waste (Olawale et al., 2015); Bamboo (Li et al., 2012, 2014); Gentiana olivieri (Evrim et al., 2016); Melon and Groundnut peels (Ita et al., 2016); Pawpaw leaves (Omotiowa and Onukwuli, 2017); Bitter kola leaf (Anadebea et al., 2018); Ocimum gratissium (Udunwa et al., 2017); Thevetia Peruvianna (Fouda et al., 2016); Mango extract (Onukwuli and Omotioma, 2016); phyllantus amarus extract (Okafor et al., 2008) Vernonia amygdalina (Loto et al., 2013), Katemfe fruit leaves (Olawale et al, 2018a, Olawale et al, 2018b) Almond fruit extract (Olawale et al, 2018a, Olawale et al, 2018b) Waterlemon (Odewunmi et al., 2015) Bitter leave root (Awe et al., 2015); Extract of Murraya koenigii Leaves (Quraishi et al., 2010); Gnetum Africana leaves (Nnanna et al., 2013); Gentiana olivieri extract (Evrim et al., 2016); Sida acuta (Umeron et al.,2016); Origanum majorana Extracts (Challouf et al., 2016) Nauclea latifolia (Uwah et al., 2013); Slavia aucheri mesatlantica (Znini et al.,2012); Pigeon pea leaf (Anadebe et al.,2019). The inhibiting activity of these plant/animal extracts is as a result of the phytochemical/physiochemical compositions such as tannins, alkanoids and amino acids.…”

Experimental, Statistical Modelling and Molecular Dynamics Simulation Concept of Sapium ellipticum Leaf Extract as Corrosion Inhibitor for Carbon Steel in Acid Environment

“…Considering the difference in E corr between the unprotected and the protected medium SE is regarded as a mixed-type inhibitor. [30][31][32][33] In conclusion, the trend of inhibition in Table 5 is due to intermolecular relationship between the protonated SE molecules and valence electrons on the Fe surface.…”

Electrochemical-kinetics, MD-simulation and multi-input single-output (MISO) modeling using adaptive neuro-fuzzy inference system (ANFIS) prediction for dexamethasone drug as eco-friendly corrosion inhibitor for mild steel in 2 M HCl electrolyte

“…This work shows that the inhibited partial reaction of mild steel is due to the adsorption of the film layer on the metal surface. This is due to the nature of the studied heterocyclic compounds which shield the metal from further dissolution [27] . In general, Q ads negative values imply that Dexamethasone molecules' surface attachment was exothermic and spontaneous.…”

“…Modeling, simulation and solving complex nonlinear problems is one of the breakthrough applications of artificial intelligence like fuzzy inference programs, ASPEN HYSIS, artificial neural network (ANN), Genetic algorithm (GA) and RSM models. Some well-respected scientists with similar research interest have used different soft computing and modeling techniques and positive results were generated [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , although the application of ANFIS is very scarce in this area. Thus, multi objective interest in this current research is to examine the interfacial adsorption and active sites of Dexamethasone drug at atomic and molecular rates using MD simulation concept, secondly for the first time, to use ANFIS model to predict the inhibition efficiency and to test the model application to pin point nonlinear complex interaction between independent variable and expected response.…”
