“…The corrosion is a natural progression that outcomes into big financial and safety losses of the industrial as well as domestic metallic assets. According to NACE, recent universal yearly cost of corrosion is nearly $ 2.5 trillion USD that contributes around 4.2% of the total GDP (gross domestic product) . In India and South Africa, annual costs of corrosion are around $ 100 billion and $ 9.6 billion USD, respectively.…”

Use of organic compounds containing nitrogen (N), oxygen (O), sulfur (S), and phosphorus (P) heteroatoms in their molecular structures is one of the most effective, economic, and practical corrosion inhibitors. The effectiveness of the heteroatoms toward metallic corrosion inhibition follows the order: P > S > N > O. The metal‐inhibitor interactions involve the charge sharing between the heteroatoms and empty d‐orbitals of the surface metallic atoms; therefore, a heteroatom with lower electronegativity value is more potent to form strong bonding (charge sharing) with metallic surface as compared to more electronegative heteroatom. Literature study reveals that almost all corrosion inhibitors have either one or more heteroatoms in their molecular structures particularly in the form of polar functional groups, which enhance their adsorption tendency on metallic surface. Present review paper features the collection of some major works that have been published on metallic corrosion inhibition containing these P, S, O, and N heteroatoms. Since now, several review articles have been published describing the application of N and O atoms; however, the reviews on use of P and S heteroatoms are scare. Therefore, aim of the present article was to mainly describe the collection of corrosion inhibitors containing S and P heteroatoms.

“…Therefore, corrosion has become worldwide problem for developed as well as developing nations to be considered by educational as well as industrial sectors [1,2]. A study conducted by National Association of Corrosion Engineers (NACE;2002) revealed that in the year 1998, United State annually losses about US $276 billion which equates about 3.1% of total U.S. gross domestic product (GDP) [3,4]. The cost of corrosion in U.S. exceeded more than US $2.2 trillion in the year 2011.…”

Dendrimers as novel class of polymeric corrosion inhibitors: A review

Dendrimers are a new class of highly branched, nano-sized, monodisperse macromolecules that have several fascinating physical and chemical characteristics. They are highly soluble in the polar solvents, contain several surface functionality and high surface area which makes them suitable reagents for industrial and biological applications. Recently, several dendrimers have been investigated as effective corrosion and scale inhibitors for metallic and silica corrosion using experimental and theoretical methods. Generally, dendrimers become effective by forming insoluble metal-dendrimer or silica-dendrimer composite on the surface. Their inhibition performance of dendrimers have been measured using several experimental such as weight loss, electrochemical (EIS and PDP) and surface (EDX, SEM and AFM) as well as computation techniques such as molecular dynamics simulation and DFT based quantum chemical calculations. The interactions between metal surface and dendrimers can be explain through some common parameters such as E HOMO , E LUMO , ∆E, electronegativity (χ), hardness (η), softness (σ), dipole moment (µ) and fraction of electron transfer (∆N). Present book chapter deals with detail description on the corrosion inhibition and anti-scaling behaviours of dendrimers for metals and silica in several electrolytic media.

“…Because of the ease of coordination of thiosemicarbazide with transition metals, they influence the latter's chemical and biological properties. Being more potent than raw thiosemicarbazones, thiosemicarbazide‐based metal complexes have received considerable attention . In this study, a new series of metal complexes were synthesized in both bulk and nano size using green methods, starting from ( E )‐ N′ ‐[( E )‐2‐bromobenzylidene]‐4‐oxo‐4‐(piperidin‐1‐yl)but‐2‐enehydrazide, and their biological activity as anticancer agents was evaluated against human hepatocellular carcinoma (HepG2) and human colorectal carcinoma (HCT‐116) cell lines.…”

A series of new metal complexes were synthesized in both bulk and nano size using green methods, starting with the reaction of (E)-N′-[(E)-2bromobenzylidene]-4-oxo-4-(piperidin-1-yl)but-2-enehydrazide with thiosemicarbazide and different metal halides such as CuI·2H 2 O, CuCl 2 ·2H 2 O, CoCl 2 ·2H 2 O, and ZnCl 2 ·2H 2 O, and metal nitrate such as Ga(NO 3 ) 3 ·2H 2 O.Structures of these metal complexes were confirmed using different spectroscopic methods, elemental analysis, electronic spectra, and microanalytical methods (scanning electron microscopy and transmission electron microscopy) for nano complexes. The distorted octahedral geometry for all complexes was suggested based on magnetic moments and electronic spectral studies. The cytotoxic activity of the compounds was investigated against human hepatocellular carcinoma (HepG2) and human colorectal carcinoma (HCT-116) cell lines. Most tested compounds had higher inhibitory activity than the standard vinblastine drug. Interestingly, the nano-sized Ga(III) complex 11 was the most potent compound against the two tested cell lines, with 50% inhibitory concentration (IC 50 ) of 2.56 μg/mL for HepG2, compared with the reference drug vinblastine (IC 50 15.6 μg/mL), and IC 50 4.64 μg/mL for HCT-116, compared with the standard (IC 50 13.9 μg/mL). The bioassay results helped us identify new potent and selective anticancer agents.
