“…The downfield shift of this signal is due to the intramolecular hydrogen bonding between OH and N atom of the quinoline ring. The signals appearing at 9.1, 9.01, 8.45 and 7.80 ppm are assigned to all the aromatic protons of the quinoline ring . The signals assigned to NH 2 and NH imino protons appear at 6.8 and 2.5 ppm, respectively.…”

A new azo dye ligand of sulfaguanidine with 5-nitro-8-hydroxyquinoline and its Mn(II), Ni(II), Co(II) and Cu(II) complexes were synthesized and characterized using elemental analysis, inductively coupled plasma, molar conductance, X-ray powder diffraction, thermogravimetric analysis, magnetic moment measurements, and infrared, 1 H NMR, electron impact mass and UV-visible spectral studies. The spectral studies and analytical data revealed that the azo dye ligand acts as a monobasic bidentate ligand via deprotonated OH and nitrogen atom of the azo group. The data support the mononuclear formulation of all complexes, except Cu(II) complex that has a binuclear formulation with a 1:2 metal to ligand ratio. The complexes have tetrahedral structure except Ni(II) which has octahedral geometry. The molar conductance data reveal that all the metal complexes are non-electrolytic in nature The average particle size of the ligand and its Mn(II), Ni(II), Co(II) and Cu(II) complexes is 0.12-0.91 nm. The effect of these compounds for improvement of chemical durability of silicate glass in 0.1 M HCl was studied. Window and soda-lime silica glass were taken as samples for the durability experiments. The inhibition efficiency of the ligand and its complexes for corrosion of glass surfaces after dissolution experiments was evaluated quantitatively using the specific weight loss method and qualitatively using scanning electron microscopy. The inhibition efficiencies of the tested compounds follow the order Co(II) complex > Mn(II) complex > Ni(II) complex > H 3 L > Cu(II) complex. The chemical durability improvement is 88.12-56.25% and 87.99-51.96% for window and soda-lime silica glass, respectively.

“…This behavior means that the film obtained acts as a barrier to the corrosion process that clearly proves the formation of the film. [25][26][27][28][29][30] When SS316L is immersed in AS containing DGlucose the blank system Rt value is 491375ohm cm 2 and Cdl value is 3.6354x10 -9 F/cm 2 . The concentration of 150ppm of D-Glucose the Rt value is increasedfrom491375 to641109 ohmcm 2 and the Cdl value decreased from 3.6354x10 -9 to 2.1481x10 -9 F/cm 2 .When compared to the blank value the 150ppm of Rtand Cdl values are high.…”

In the oral environment, orthodontic appliances are exposed to potentially damaging Physical and chemical agents which may cause metallic corrosion. The study reveals that there is a strong dependence of the corrosion resistance of SS316L on the concentration of D-Glucose in the electrolyte medium. The corrosion behavior of experimental Stainless steel 316L alloy has been carried under artificial saliva (AS) condition in presence of D-Glucose. Corrosion resistance and ability to form protective oxide scales are evaluated and compared with polarization study and AC impedance spectra. The SS316L orthodontic alloy so better corrosion resistance in all experimental condition than other alloys. This agrees with the results obtained potentiodynamic polarization curves and AC impedance spectra.

“…The spectrum showed signals at 9.16, 9.12, and 8.55 ppm, which are assigned to the OH, NH, and CH═N protons, respectively. The downfield shift of the OH group is due to intramolecular hydrogen bonding between OH and N‐atom of the quinoline ring . A total of 11 aromatic protons of quinoline, phenyl, and pyrimidine rings were observed in the region of 9.00–6.56 ppm.…”

A new azo dye ligand of sulfadiazine with 5‐nitro‐8‐hydroxyquinoline (H2L) and its Cu(II), Mn(II), Co(II), and Ni(II) complexes have been synthesized and characterized using CHN, 1H NMR, EI‐mass, inductive coupled plasma, molar conductance, IR, thermogravimetric analysis, magnetic moment measurements, and UV–vis spectra. On the basis of spectral studies and analytical data, the azo dye acts as a monobasic bidentate ligand coordinating to the metal ions via deprotonated OH and azo nitrogen atom. The spectral data showed that the synthesized complexes have octahedral geometry. The application of the obtained chelates in the oxidative decomposition of three different textile dyes (i.e., AB92, AB40, and AB129) in the presence of H2O2 as an oxidant has been studied. The obtained results indicated that the reactivity of catalysts toward the decolorization of AB40 showed the following order: Cu complex > Ni complex > Co complex > Mn complex; the reactions obey the first‐order reaction mechanism, and the rate constants were determined.
