a nanocomposite of polyaniline (pani) with natural clinoptilolite (clino) was prepared by chemical oxidative polymerization of anilinium cations in the presence of clinoptilolite dispersion. the pani/clino nanocomposite was characterized using ftir, xrd and sem techniques as well as electrical conductivity measurement using four point probe technique. cyclic voltammetry analysis was used to inv...

BACKGROUND This article reports the authors' development of nanofillers and a resulting nanocomposite. They measured the nanocomposite's properties in vitro in comparison with those of several existing composites (hybrids, microhybrids and microfill). METHODS The authors developed two types of nanofillers: nanomeric particles and nanoclusters. They used optimal combinations of these nanofille...

Nanocomposite of NiAl2O4/SiO2 (NAS) was prepared through insitu solgel reaction, in which NiAl2O4 nanocrystals were dispersed in the silica glassy matrix. The prepared dried NAS gel, at 338 K, was heat treated to different temperature and identified the temperature range (1083 – 1163 K) of the nanocomposite formation through XRD patterns. From XRD patterns, crystallite size of NiAl2O4 particles...

This paper demonstrates an acetylene gas sensor based on an Ag-decorated tin dioxide/reduced graphene oxide (Ag-SnO₂/rGO) nanocomposite film, prepared by layer-by-layer (LbL) self-assembly technology. The as-prepared Ag-SnO₂/rGO nanocomposite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectrum. The acetylene...

In the current work, a novel combustion method is demonstrated for the direct synthesis of nanocomposite materials. Specifically doped tin dioxide (SnO2) powders were selected for the demonstration studies due to the key role SnO2 plays in semiconductor gas sensors and the strong sensitivity of doped SnO2 to nanocomposite properties. The synthesis approach combines solid and gas-phase precursor...

Ni-Fe/Si3N4 nanocomposite coatings with various ratio of Si3N4 to Na-saccharine were prepared by electrodeposition technique. The effect of Si3N4 nanoparticulates in the Ni-Fe nanocomposite coatings was investigated in relation to the ratio of Si3N4 to Na-saccharine in the plating bath. X-ray diffraction analysis showed that the Ni-Fe nanocomposite coating has face center cubic structure (FCC)....

A novel nanocomposite based on poly(N-octadecyl-2-ethynylpyridinium bromide) (PNOEtPyBr) and Mg(0.04)Nb(1.66)O5 nanosheets is synthesized by the method of exfoliation-reflocculation. The XRD data of the nanocomposite indicates the formation of Mg(0.04)Nb(1.66)O5 nanosheets/PNOEtPyBr nanostructure with an interlayer expansion of 4.6 nm along a direction perpendicular to the Mg(0.04)Nb(1.66)O5 na...

A new and inexpensive lignocellulose/montmorillonite (LNC/MMT) nanocomposite was prepared by a chemical intercalation of LNC into MMT and was subsequently investigated as an adsorbent in batch systems for the adsorption-desorption of Ni(II) ions in an aqueous solution. The optimum conditions for the Ni(II) ion adsorption capacity of the LNC/MMT nanocomposite were studied in detail by varying pa...
