Immobilization of bacterial S-layer proteins from Caulobacter crescentus on iron oxide-based nanocomposite: Synthesis and spectroscopic characterization of zincite-coated Fe2O3 nanoparticles

Cobalt ferrite nano-composite coated on glass by Doctor Blade method for photo-catalytic degradation of an azo textile dye Reactive Red 4: XRD, FESEM and DRS investigations

“…The application of nano-size photo-catalysts in degradation of organic pollutants in aqueous environment has concerned much interest due to their large surface area [6][7][8][9][10][11]. Semiconductor nano-particles have attracted many interests for their interesting properties and applications in photocatalysis [12][13][14][15]. Among semiconductor nanoparticles, zinc oxide and titania with wide band gaps are widely used as photocatalyst [16,17].…”

Functional biocompatible magnetite–cellulose nanocomposite fibrous networks: Characterization by fourier transformed infrared spectroscopy, X-ray powder diffraction and field emission scanning electron microscopy analysis

“…The peaks of Fe3O4 in the XRD pattern of nanocomposite confirm existence of the nanoparticles in the amino cellulose matrix. Therefore, magnetic Fe 3 O 4 nanoparticles were successfully synthesized in the micropores of the cellulose [38][39][40][41][42]. The mean crystallite size of the synthesized magnetic Fe 3 O 4 nanoparticles was determined to be 28 nm, as calculated according to the width of the (4 4 0) XRD peak at half height, using the Scherer's equation, (0.9k)/(b cos h), by measuring the line broadening of main intensity peak, where k is the wavelength of Cu Ka radiation, b is the full width at half-maximum, and h is the Brag's angle [43].…”

Diphenylalanine peptide nanotubes self‐assembled on functionalized metal surfaces for potential application in drug‐eluting stent

“…Field emission scanning electron microscope micrographs were taken using a FE‐SEM, Hitachi, and model S‐4160 . IR absorption spectra of selected samples were obtained using KBr disks on a FTIR 6300 . Size distribution of the assembled nanostructures in solution was analyzed by DLS using Malvern Zetasizer Nano ZS.…”

“…44,45 IR absorption spectra of selected samples were obtained using KBr disks on a FTIR 6300. 46,47 Size distribution of the assembled nanostructures in solution was analyzed by DLS using Malvern Zetasizer Nano ZS. The experiment was carried out using a 633 nm laser at 258C.…”
