Colloidal perovskite oxide nanocrystals have attracted a great deal of interest owing to the ability to tune physical properties by virtue of the nanoscale, and generate thin film structures under mild chemical conditions, relying on self-assembly or heterogeneous mixing. This is particularly true for ferroelectric/dielectric perovskite oxide materials, for which device applications cover piezo...

In this work, growth and assembly of the micro polyhedral zinc oxide was performed using airbubble assisted Triton X100, as a templating agent. In absence of air bubbling in the reactionsystem the nano plate zinc oxide was synthesized. The prepared samples were characterized by Xraydiffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-Visspectrop...

Objective(s): Nowadays, tendency to use green materials can reduce environmental pollution and plastic waste. Poly (lactic Acid) PLA is one of the natural biodegradable polymers mainly used in the production of bioplastics for packaging which is made of non-toxic compounds and is easily biodegradable. In this research, the effect of 1, 3 and 5% nanocomposite zinc oxide on the morphological, mec...

Silicon nanocrystals embedded in SiO2 were isolated with a selective etching procedure, and the isolated nanocrystals’ excitonic emission energy was studied during controlled oxidation. Nanocrystals having initial diameters, d0, of ,2.9–3.4 nm showed a photoluminescence sPLd blueshift upon oxidatively induced size reduction, as expected from models of quantum confinement. Oxidation of smaller S...

Zinc deficiency is a global nutritional disorder affecting majority of healthy people rather than those suffering from chronic diseases, affects about one third of people around the world and thereby causing clinical manifestations. This work represents new modality to increase the intestinal absorptivity and bioavailability of zinc from the diet by replacing traditional bulk form by zinc nanop...

In this work, zinc ferrite magnetic and zinc ferrite-graphene oxide nanocomposite were synthesized through a facile hydrothermal method and dye removal capability as an adsorbent were studied. Fourier transform infrared spectroscopy FT-IR, X-ray diffraction XRD and scanning electron microscopy SEM were used to characterize the synthesized nanocomposite. The UV-Vis results showed that the additi...

Zinc oxide (ZnO) has emerged as a leading material for microand optoelectronic applications. Although the fabrication of ZnO, from nanocrystals to bulk single crystals, is well established, a major roadblock for fabricating optoelectronic devices is the lack of reliable p-type doping. The presence of compensating donors inhibits the growth of p-type ZnO. In this paper, studies pertaining to the...
