Corrosion Inhibition Behavior of Different Chain Lengths Pyridine Ionic Liquid for N80 Steel in Hydrochloric Acid Solution
Published 2021-06-01“…In order to obtain ionic liquid inhibitors with lower concentration and higher efficiency than idazolines, the corrosion inhibition behaviors of N80 steel in hydrochloric acid solution with different concentrations of Pyridine ionic liquids including B4MePyBr, O4MePyBr and dimethyl sulfate pyridinium quaternary ammonium salt corrosion inhibitor were studied by using weight loss experiments, electrochemical tests, scanning electron microscope(SEM)and atomic force microscope(AFM).The weight loss experiments indicated that the corrosion inhibition efficiency was improved as the concentration of the three kinds of inhibitors increased.Under the conditions of 25 ℃ and 10 mmol/L of O4MePyBr, the corrosion inhibition efficiency could increase to more than 90%, and the maximum efficiency order of them was O4MePyBr > B4MePyBr > dimethyl sulfate pyridine quaternary ammonium salt.Based on electrochemical tests, all of three inhibitors belonged to the mixed-type corrosion inhibitors.From surface morphology analysis, the inhibitor could be effectively adsorbed on the surface of carbon steel, and the adsorption layer was very dense.Besides, the adsorption of three inhibitors the carbon steel surface followed the Langmuir isotherm.…”

Published 2025-03-01“…We constructed SCNs based on cortical thickness data and analyzed the changes in global and regional network measures of PHN patients and herpes zoster (HZ) patients, and get hubs of each group.Results: (1) PHN patients with a disease duration > 6 months had reduced global efficiency (P=0.035) and increased characteristic shortest path length (P=0.028). (2) Nodal efficiency of the right pars opercularis was greater in both HZ and PHN patients with a disease duration of 1 to 3 months (P< 0.001); in PHN patients with a disease duration > 6 months, the nodal degree of the left pars triangularis and nodal efficiency of the right middle temporal gyrus were greater (P< 0.001). (3) The right supramarginal gyrus was the common hub of healthy controls (HCs) and HZ patients, the right pars opercularis was the common hub of HZ patients and PHN patients with a disease duration of 1 to 3 months, and the bilateral superior frontal gyrus was the common hub of HZ patients and PHN patients with a disease duration > 6 months.Conclusion: There have changes in SCN indices in PHN patients with different disease durations. …”
