A novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. The nanocomposite was prepared using a domestic microwave oven. The prepared nanocomposites have been characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and UV- visible spectroscopy. The crystalline properties...

Vitamin B₉ or folic acid is an important food supplement with wide clinical applications. Due to its importance and its side effects in pregnant women, fast determination of this vitamin is very important. In this study we present a new fast and sensitive voltammetric sensor for the analysis of trace levels of vitamin B₉ using a carbon paste electrode (CPE) modified with 1,3-dipropylimidazolium...

A Fe3O4@ZnO/C nanocomposite with a core-shell structure was synthesized using the co-precipitation method. To prevent aggregation of Fe3O4 magnetic particles, polyethylene glycol (PEG) added. The X-ray diffractometer (XRD) results confirmed formation and ZnO phases, having cubic crystal system hexagonal system. Carbon in had no effect on Fe3O4@ZnO. Images from transmission electron microscopy (...

Background and Objective: Due to the water shortages and the presence of industrial pollutants in water resources, wastewater treatment, especially colored wastewater, is essential. The aim of this study was to treat wastewater containing Methylene Blue dye using activated carbon nanocomposite/zinc oxide nanoparticles (ZnO/AC) obtained from canola oil waste by green method. Materials and Metho...

In the present work, metallic oxide–organic material hybrid nanocomposites (Poly vinyl pyrrolidone- zinc oxide, PVP-ZnO) have been synthesized using sol-gel method. Nanostructural properties of aforementioned materials were studied by scanning electron microscope (SEM) and X-ray diffraction techniques. Williamson equation was used to estimate lattice strain in the PVP-ZnO nanocomposite. The dom...
