1. FTIR, 1H, and 13C NMR spectroscopy were used to determine the structure and compositions of the copolymers. Figure 1 Schematic representation for the synthesis of Poly (STY-co-AMPS) copolymer. Full size image Nanofluids preparation The synthesis and characterisation of ZnO NPs were described ...
The structural analysis is carried out using X-ray diffraction (XRD) graph which reveals both cubic (NiO) and hexagonal (ZnO) phases. Chemical bonding, morphology, elemental composition and optical properties of prepared nanocomposites are investigated by Fourier Transform Infrared (FTIR) Spectroscopy,...
Fig. 4. FTIR of ZnO with latex of Euphorbia Jatropa as fuel. 3.4. Scanning electron microscopy (SEM)–EDS Fig. 5 shows SEM images with EDS graph and histogram of ZnO nanoparticles. From the SEM images it was observed that the particles were well shaped. Most of the particles were hexago...
The FTIR spectra of ZnO NPs showed distinct peaks in the regions 3403.50, 1648.45, 1384.63, and 834.32 cm−1. The peaks have confirmed the presence of C = C–H, C = C (stretch), C–H (bend), and C = C (stretch) respectively in ZnO NPs (Fig.6) as they were sy...
The PDI value of 0.475 refers to the variation in nanoparticle size which may be attributed to the presence of some aggregation that appeared in the TEM graph. Fig. 1 Biosynthesis and characterization of ZnO-NPs; (A) Visual observation of ZnO-NPs formation and UV; (B) TEM (C) FTIR; (...
A graph of Peak potential (Ep) against log ʋ was found to have a linear relation Ep=0.05489 log ʋ+ 1.0114; r2=0.9955), and even the heterogeneous constant k0 has been determined from Ep vs. log ʋ plot’s intercept and which was found to be 3.2322 × 103 s−1. The ...
Signifies the characters of the myco-fabricated ZnO/MnO nanocomposite (A): FTIR spectroscopy for an endophytic extract ofClonostachys roseastrain EG99 (black pattern) and a mycofabricated ZnO/MnO nanocomposite (red pattern), (B): TGA and DTA analysis, (C): particle size distribution, and (D)...
FTIRDFTThe ecological friendly and readily biodegradable amino acid based surfactant, aspartic di-dodecyl ester hydrochloride acid (ADH) and its ZnO-NPs derivative was synthesized and tested as corrosion inhibitor for metal in acidic medium. The synthesized surfactant was characterized by experimental and...
The hybrid nature of the films was studied using the FTIR characterization method before and after annealing. The FTIR spectrum of the hybrid film between 400 and 4000 cm− 1 indicated the characteristics of the ZnO–Polymer nanostructured hybrid film which was prepared with PVA (Fig. 3A). Th...
The complexation between ZnO/TiO2 NPs and the polymer matrix could also influence the FTIR spectra. PVA/PEO composite exhibits transmittance bands at 2876 cm-1, which are associated with –CH2 asymmetric stretching and –CH asymmetric stretching, and 1471 cm−1, which have been related to C-...
