“…Every effort has advantages and disadvantages unique to it. Nevertheless, it has been proven that one of the best and most widely used techniques in aqueous electrolytes is the employment of organic molecules [ 10 , 11 , 12 , 13 ]. Numerous organic compound families, particularly heterocycle ones, are widely used in corrosion prevention [ 14 , 15 , 16 ].…”

Recent studies indicate that surfactants are a relatively new and effective class of corrosion inhibitors that almost entirely meet the criteria for a chemical to be used as an aqueous phase corrosion inhibitor. They possess the ideal hydrophilicity to hydrophobicity ratio, which is crucial for effective interfacial interactions. In this study, a coconut-based non-ionic surfactant, namely, coco monoethanolamide (CMEA), was investigated for corrosion inhibition behaviour against mild steel (MS) in 1 M HCl employing the experimental and computational techniques. The surface morphology was studied employing the scanning electron microscope (SEM), atomic force microscope (AFM), and contact measurements. The critical micelle concentration (CMC) was evaluated to be 0.556 mM and the surface tension corresponding to the CMC was 65.28 mN/m. CMEA manifests the best inhibition efficiency (η%) of 99.01% at 0.6163 mM (at 60 °C). CMEA performs as a mixed-type inhibitor and its adsorption at the MS/1 M HCl interface followed the Langmuir isotherm. The theoretical findings from density functional theory (DFT), Monte Carlo (MC), and molecular dynamics (MD) simulations accorded with the experimental findings. The MC simulation’s assessment of CMEA’s high adsorption energy (−185 Kcal/mol) proved that the CMEA efficiently and spontaneously adsorbs at the interface.

“…On the other hand, chelate ligand 1,10-phenanthroline (phen) acts as an ending-seal function, inhibiting the 2D or 3D extension of Ni(II), thus forming the 1D structures (Scheme S1). Two spatially auxiliary ligands tend to block the H 6 L sites for the optimization of structures and improve the skeleton stability of the MOFs by π–π interactions and supramolecular interplays. − Furthermore, the electrochemical glucose-sensing performance of as-synthesized Ni(II)-MOFs was measured systematically, and the structure–activity relationship was elucidated. At optimal conditions, CTGU-34 exhibits a record response time of less than 0.4 s, which is superior to the reported nonenzymatic electrochemical sensors.…”

“…6 Bismarck Brown Y (BB) dye is widely used in staining of biological tissues and tanning of leather. 7 It goes as waste in the later industries which leads to water pollution. 8 Hence, if the dye could be recovered and profitably used in the synthesis of fluorescent probes, photovoltaic devices and light emitting diodes, it can not only solve the problem of water pollution but also save the cost of designing multifunctional polymers.…”

The present work reports, for the first time, synthesis of dye incorporated o-phenylenediamine (OBB) with a view to obtain a conjugated oligomer with enhanced functionality. The structure was confirmed by IR studies, while the electronic transitions were confirmed by UV visible studies. The dye modified oligomer showed one order higher fluorescence intensity than the pristine Bismarck Brown (BB) dye. Confocal imaging showed red emission which could be utilized in near infra-red imaging. Density functional theory (DFT) studies were carried out to predict the theoretical properties of the oligomers. The energies of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital orbital were computed to explore how the HOMO energies of the reactants initiated the electronic interactions between them. The interaction energies were correlated to conjugation/hyper conjugation stabilization energies of the natural bond orbitals (NBO) via the DFT method using the B3LYP functional with the 6-311G(d) basis set on Gaussian 09 software. Drug binding was evaluated through simulation of interaction energy, (ΔE A–x ) with drugs such as captopril, propranolol, thiazide, and fentanyl. The results predicted that the oligomer could be developed into a fentanyl drug sensor.
