The effect of surface morphology and treatment of Fe 3 O 4 nanoparticles on the corrosion resistance of epoxy coating

Developing a Fluorescent Hybrid Nanobiosensor Based on Quantum Dots and Azoreductase Enzyme forMethyl Red Monitoring

“…As it can be seen in this Figure, the FTIR spectra of CdSe/ZnS-OLA showed a sharp peak at 3744 cm -1 , which is related to the stretching vibration of N-H bonds, indicating that the NH 2 -containing ligand was adsorbed on the synthesized QD surface [ 63 ] . The broad absorption peak at about 3200-3600 cm -1 can be assigned to the –OH stretching vibration of physically adsorbed water molecules in CdSe/ZnS and CdSe/ZnS-MPA samples [ 64 ] . The significant reduction of the peak in CdSe/ZnS-OLA sample indicates that the sample has more hydrophobic property than the two other samples.…”

Poly(Caprolactone)‐Poly(N‐Isopropyl Acrylamide)‐Fe3O4 Magnetic Nanofibrous Structure with Stimuli Responsive Drug Release

“…[ 29 ] The characteristic bands of PNIPAAm at 1387, 1653, and 3300 cm −1 are corresponding to CH 2 , NH 2 , and NHOH groups, respectively. [ 30 ] Peaks at 3448 cm −1 indicate FeOH bond [ 31 ] and at 585 cm −1 the absorption bands of FeO in magnetite is detected, [ 32 ] which intensifies at higher concentration of MNP in fiber.…”

A study of the corrosion of stainless steel 304L coated with a 190 nm-thick manganese layer and annealed with nitrogen flux in a 0.4-mole solution of H2SO4 at different temperatures

“…It is well-known that a passive film formed from a mixture of iron and chromium oxides/hydroxide on the electrolyte/electrode interface leads to decrease in the electrode corrosion rate in corrosive media [5]. However, some techniques such as using from corrosion inhibitors [6][7][8][9][10], alloying elements [11][12][13], and organic [14][15][16] or inorganic [17][18][19][20] coatings have been proposed by many researchers to enhance the corrosion resistance in corrosive solutions.…”
