Nano-architecture of CaO/Ag-chitosan nanocomposite by sol gel process: formation and characterization

“…The operation of metal oxides as an active photocatalytic is significantly improved by their structural compositions and surface defects. This due to that the doping of metal oxides with metal and/or metals raises surface defects, improves optical and electronic properties, and transfers optical absorption into the visible region [13][14][15]. To evolve the metalorganic composites as good platforms for various applications, alkaline metal oxides have been well purposed as organic linkers with metal-organic composites because of their excellent structural, catalytic, and antimicrobial activities.…”

“…CaO nanoparticles are one of the successful nanofiller employed in the fabrication of hybrid nanocomposite arrangements, owing to their homogenous nanoparticles size and sizeable penetration within the polymer layers [32]. The chemical polymerization sol-gel route is the strategic technique for the fabrication of films, nanoparticles, and porous ceramics based on inorganic molecules [11,14,33]. For fabrication of the chitosan nanocomposite with nano-Ca and nano-Ca/Ag ionspromising properties, the nanofillers should offer a small distribution in diameter size and highly dispersed in the chitosan matrix [34].…”

Adjusting the Effects of Cr3+ Doping on Structural, Dielectric, Antimicrobial Properties of Delafossite SrCuO2 Nanoparticle

“…30,35 The decrease in FTIR band width at 856 cm −1 and 1454 cm −1 as the Cr concentration increases can be attributed to the removal of OH and unbounded groups (Sr-OH, Cu-OH, Sr-O-) from the internal arrangement, along with the promotion of structural uniformity facilitated by the Cr-O-. 4,16 Distinctive visible and near-infrared (FT-IR) spectra exhibiting multiple peak maxima within the 500 to 1100 cm −1 range were observed in all samples. The characteristics of these peaks have been attributed to the incorporation of Cr ions into the polycrystalline SrCuO 2 nanostructure.…”

Sol-Gel/Gel Casting Nanoarchitectonics of Hybrid Fe2O3–ZnO/PS-PEG Nanocomposites and Their Optomagnetic Properties

“…The change in XRD peak intensities within the 2θ range 29°-65° and the differences in some XRD peak intensities were mainly attributable to the change in Fe 2 O 3 levels in the PS-PEG-based with increasing ZnO ratio. According to Debye-Scherrer's equation [21], the three predominant XRD peaks at 2θ = 36.53°, 37.76°, and 44° are used to evaluate the crystallite size. The evaluated crystallite size increases from ~ 17 nm (PS-PEG-Fe 2 O 3 ) up to ~ 20.79 nm (PS-PEG-Fe 2 O 3 /ZnO).…”
