A cotton-like ZnO/SnO2 nanocomposite was grown by the carbothermal evaporation of a mixture of ZnO and SnO2 powders at 1100oC by the vapour-liquidsolid process, in which the Sn particles produced by the reduction of SnO2 act as the catalyst. Field-emission scanning electron microscope images suggest that the composites are made of microfibre-nanowire junction arrays. The structure is formed due...

Pectin-ZnO nanocomposite was prepared in the aqueous solution condition at room temperature. The Fourier transform infrared, X-ray diffraction, and transmission electron microscope (TEM) measurements confirmed the nanoscaled structure of pectin-ZnO composite. According to the TEM observation, the average composite granules size was about 150 nm and the embedded ZnO nanoparticles were uniform wi...

ZnO/ PEG Nanocomposite material is synthesized by laser ablation of pure Zn target in the mix solution of PEG and of water in different compositions. Synthesized Nanocomposite materials are characterized by using UV-visible absorption, Transmission electron microscope (TEM) and Photoluminescence (PL) spectroscopic techniques. TEM investigation illustrates synthesis of few 2-5 nm quantum dots wi...

Strawberries have a very short post-harvest life mostly due to their relatively high water content, intense metabolic activity and susceptibility to microbial rot. Antimicrobial low-density polyethylene nanocomposite films containing ZnO nanoparticles at different mass fractions were prepared by melt mixing and followed by compression moulding using a hot press machine. Fresh strawberries were ...

The Cu/ZnO nanocomposite films have been synthesized by cathodic electrodeposition and characterized using X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), photoluminescence (PL) and field emission microscope (FEM). The XRD pattern shows a set of well defined diffraction peaks, which could be indexed to the wurtzite hexagonal phase of ZnO. ...

Zinc oxide (ZnO) nanorods decorated with gold (Au) nanoparticles have been synthesized and used to fabricate dye-sensitized solar cells (DSSC). The picosecond-resolved, time-correlated single-photon-count (TCSPC) spectroscopy technique was used to explore the charge-transfer mechanism in the ZnO/Au-nanocomposite DSSC. Due to the formation of the Schottky barrier at the ZnO/Au interface and the ...

In this research, firstly polyaniline-zinc oxide (PANI-ZnO) nanocomposite was successfully synthesized by chemical polymerization of aniline in the presence of ZnO nanoparticles and then, 5%, 10% and 15% solutions of PANI–ZnO nanocomposites were mixed with a solution of polystyrene (PS) in tetrahydrofurane (THF) and PANI-PS-ZnO nanocomposites were obtained. The prepared nanocomposites were used...

We report the characterization of mixed oxides nanocomposite nanofibers of (1 - x) ZnO-(x)SnO2 (x ≤ 0.45) synthesized by electrospinning technique. The diameter of calcined nanofibers depends on Sn content. Other phases like SnO, ZnSnO3, and Zn2SnO4 were absent. Photoluminescence studies show that there is a change in the blue/violet luminescence confirming the presence of Sn in Zn-rich composi...
