Nano is an advanced technology which in recent years has had numerous applications in different fields such as industry, biotechnology, energy, environment and etc. In this paper, ZnO nanoparticles were synthesized by simple method of precipitation sounds more plausible. ZnSO4 and NH4OH were used as precursors to yield ZnO powders. The synthesized ZnO nanoparticles were characterized by X-ray d...

One-dimensional single crystal incorporating functional nanoparticles of other materials could be an interesting platform for various applications. We studied the encapsulation of nanoparticles into single-crystal ZnO nanorods by exploiting the crystal growth of ZnO in aqueous solution. Two types of nanodiamonds with mean diameters of 10 nm and 40 nm, respectively, and polymer nanobeads with si...

Novel magnetic composite nanoparticles (MCPs) were successfully synthesized by ex situ conjugation of synthesized ZnO nanoparticles (ZnO NPs) and Fe3O4 NPs using trisodium citrate as linker with an aim to retain key properties of both NPs viz. inherent selectivity towards cancerous cell and superparamagnetic nature, respectively, on a single system. Successful characterization of synthesized na...

In this paper, we report deposition of ZnO nanoparticles on stainless steel orthodontic wires by chemical solution method for the first time. The prepared samples were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) coupled with energy dispersive x-ray analysis (EDX), visibleultraviolet diffuse reflectance spectroscopy (DRS) and transmission electron microscope (TEM...

ZnO nanorods decorated with gold nanoparticles of ~20 nm average size were fabricated by microwave-assisted chemical synthesis. For the surface-attached growth of metal nanoparticles, the ZnO nanostructures were first functionalized by sodium citrate and then the metal ions were reduced under microwave heating. While the incorporation of gold nanoparticles at the surface seen to quench both the...

In this study, perfluorinated phosphonic acid modifications were utilized to modify zinc oxide (ZnO) nanoparticles because they create a more stable surface due to the electronegativity of the perfluoro head group. Specifically, 12-pentafluorophenoxydodecylphosphonic acid, 2,3,4,5,6-pentafluorobenzylphosphonic acid, and (1H,1H,2H,2H-perfluorododecyl)phosphonic acid have been used to form thin f...

nanostructured zinc oxide (zno) materials have received considerable interest from scientists due to their remarkable performance in electronics, optics and photonics. zno nanoparticles were synthesized by co-precipitation method. zno nanoparticles were synthesized using zn(no3)3 and k2co3 precursors. the structure of the obtained product was confirmed by the powder x-ray diffraction (xrd) anal...

unsubstituted phthalocyanines of co, fe and mn supported on zinc oxide nanoparticles were prepared and were well characterized with x-ray diffraction (xrd) and scanning electron microscopy (sem). the oxidation of alcohols with tert-butylhydroperoxide (tbhp), in the presence of metallophthalocyanines (mpc) supported on zinc oxide nanoparticles was investigated. these mpc/zno nanocomposites were ...

The performance of hybrid solar cells composed of polymer and ZnO is mainly hindered by the defects of ZnO. Here, we investigate the effects of ZnO nanoparticle surface modification with poly(ethylene oxide) (PEO) on the performance of bulk heterojunction hybrid solar cells based on poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) and ZnO nanoparticles. The reference devic...

ZnO-NPs suspended in distilled water were administered to Wistar rats at dose of 10 mg/ kg body weight through oral gavage for 5 consecutive days. The mean body weight gain in rats given ZnO-NPs was similar to this of control group, so no significant differences in the relative organs weight were observed between the ZnO-NPs treated-rats and control. Moreover, ZnO-NPs-exposed rats showed normal...
