Corrosion Inhibition Performances of Imidazole Derivatives-Based New Ionic Liquids on Carbon Steel in Brackish Water

In this study, imidazole derivative-based new ionic liquids were investigated as corrosion inhibitors. These new ionic liquids (ILs) are 1,3-dipropyl-2-(2-propoxyphenyl)-4,5-diphenylimidazole iodide (IL1) and 1,3-dibutyl-2-(2-butoxyphenyl)-4,5-diphenylimidazole iodide (IL2). The corrosion inhibition effects of two new ILs were observed on carbon steel in brackish water media (1% NaCl solution). Carbon steel coupons were exposed to 1% NaCl solution with various concentrations of ILs. Corrosion inhibition effects were tested by the electrochemical impedance spectroscopy (EIS) method and the Tafel method at various temperatures ranging from 25 degrees C to 55 degrees C. The results showed that ILs have potential as corrosion inhibitors and the adsorption mechanisms of IL1 and IL2 on carbon steel surfaces were also determined, which followed the Langmuir adsorption isotherm model. Acquisition of increment G(ads) values of IL1 and IL2 were -35.04 and -34.04 kJ/mol, respectively. The thermodynamic data of the ILs show that semi-chemical and or physical adsorptions occurred on carbon steel surfaces.

Crystallization Processes through Self-assembled Materials Dependent on the Substituents of Tetrapodal Adamantanes

Three tetrapodal tetraaryladamantanes bearing imidazole derivatives exhibit unique self-assembly and crystallization behaviors, including hollow spherical aggregation, a morphological change by fusion events, and phase transition into crystals. In crystals, the packing and arrangements of tetrapodal adamantanes are subject to the substituents of imidazole derivatives in the molecules.

Influence of functionalised multiwalled carbon nanotubes with imidazole derivative and thiosemicarbazide on MKN45 and SW742 cancer cells

Carboxylated multiwall carbon nanotubes (MWCNT-COOH) were first modified by an imidazole derivative, 2-amino-1-methyl-5-(3,4,5-trimethoxybenzylidene)-1H-imidazol-4(5H)-one, to form a MWCNT-Im and then by thiosemicarbazide to produce MWCNT-Py. All products were characterised by Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscope, energy dispersive X-ray spectroscopy, solubility test, thermogravimetric analysis, derivative thermogravimetric and cellular investigations. These functionalisations have been chosen due to active sites of C=C and carbonyl groups in MWCNT-Im and NH2 and sulphur groups in MWCNT-Py, which might be used as functional materials in future. Toxicity of these samples was evaluated with human gastric (MKN45) and colon (SW742) cancer cells, and the killed cell numbers were measured by reduction in living cells with 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) after 48 h of cell culture experiments. Cellular investigations showed high toxicity of modified MWCNTs on the gastric cancer cells compared to colon cells. In addition, MWCNT-Py sample indicated the highest toxicity for both cancer cells compared to other samples.

Induction of CYPIA by the N-imidazole derivative, 1-benzylimidazole

Xenobiotics can induce cytochrome P4501A (CYP1A) by ligand binding to the aryl hydrocarbon receptor (AhR). Typical AhR ligands are polycyclic aromatic compounds with planar molecular conformation. The present work investigated the ability of the N-imidazole derivative, 1-benzylimidazole (BIM), to induce CYP1A in rainbow trout hepatocytes. Benzylimidazole increased hepatocellular CYP1A catalytic activity (determined as 7-ethoxyresorufin-O-deethylase [EROD] activity) and CYP1A mRNA in a concentration-dependent way. Computational studies on the molecular structure of BIM indicated that the energetically most stable BIM conformer has the imidazole ring and the phenyl ring in different planes, i.e., does not take a planar conformation. This property of BIM does not agree with the structural requirements of a typical AhR ligand. In line with this observation, we found that the AhR antagonist, alpha-naphthoflavone (alphaNF), was not able to inhibit BIM induction of EROD activity and CYP1A mRNA, although it inhibited the induction of CYP1A by the prototypic AhR ligand, alpha-naphthoflavone (betaNF). The results suggest that transcriptional activation of CYP1A by the N-imidazole derivative, BIM, is not mediated through direct ligand binding to the AhR.

Copper corrosion inhibitors in near neutral media

The efficiency of nontoxic imidazole derivatives as copper corrosion inhibitors in sodium chloride solutions was studied by electrochemical polarization methods (Tafel extrapolation and polarization resistance method) and weight-loss measurements. Results obtained during this study show that inhibitors with higher molecular weight, especially those with a phenyl ring, have better inhibiting properties. The values of free energy of adsorption, as calculated from Freundlich isotherm, indicate that investigated imidazole derivatives physisorbe on the copper surface. (C) 2002 Elsevier Science Ltd.
