“…The other appointed range (b) stretched from 2600cm −1 to 3200 cm −1 and was entailed by oscillation of alkyl and amino groups of the polymer. According to literature two peaks of 580 cm −1 and 3030 cm −1 are absent in purified polyacrylic acid. Therefore an amine bond between polyacrylic acid and octylamine can be suggested.…”

Magnetic properties of colloidal nanoparticles (NPs) depend on various parameters, such as size, size distribution, interparticle distance, shape, condition of synthesis and stabilizing surfactants. Nowadays, those magnetic nanoparticles (MNPs) are preferably produced in hydrophobic organic solvents, while biomedical applications need hydrophilic properties. Thus, a major challenge is the hydrophilization of the particles, while avoiding destabilization and aggregation. Here we present magnetic characteristics of noninteracting, highly crystalline iron oxide NPs in physiological solutions that are coated with modified polyacrylic acid. The magnetic analysis comprised both static and dynamic magnetic behaviour of 4 nm NPs. The NPs have been further characterized by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX).

“…The nanoparticulate surface areas ( S BET ) of the synthesized nanofiber are 51 and 45 m 2 /g, and they were derived from BET analyses at calcination temperatures up to 500 and 600 °C, respectively. Values of S BET for the niobia nanofibers were determined by means of the BET approach …”

“…The strong peaks at 2930 cm −1 represent C−H stretching vibration, while those at 1685 cm −1 could be linked with CO carbonyl bonds. 34 Raman peaks from the C−C bond and CH 2 twisting signals could also be located around 1320 and 1120 cm −1 . 34,35 Vibration signals linked with C−COOH and C−CH 2 stretching are responsible for the peaks at 846 and 1086 cm −1 , respectively; other peaks are indicated on the spectra.…”

In the present study, the corrosion resistance of a new niobium oxide/acrylate hybrid nanocomposite coating doped with niobia nanofibers is investigated. Nanofibers were initially synthesized from niobium(V) chloride precursor in a novel autoclave approach before fabricating the base coating from a two-step process involving the syntheses of acrylate resin via free radical polymerization and niobium oxide gel from niobium ethoxide via a sol–gel technique. Variants of the synthesized nanocomposite coating were incorporated with varying concentrations of niobia nanofibers before spin-coating on Q235 steel substrates to inhibit corrosive electrolytic ion percolation and further enhance corrosion resistance when treated with chloride-enriched corrosive media. The corrosion resistance of these nanocomposite coatings increased with nanofiber content up to an optimum concentration due to the corrosion-inhibiting and protective effects of niobium barrier layers within these coatings. The presence of the niobia nanofibers also promoted improved surface contact angle and toughened mechanical strengths.
