Research work reports the synthesis method of nanocomposite ZnO/CuO/β-CD and it is characterized by X-ray diffraction UV-vis absorption spectra. Photocatalytic activity measured using organic dye Malachite Green (MG) as model pollutant. Dye degradation follow pseudo first order kinetics. Efficiency photocatalytic process percentage degradation. Rate constant band gap also calculated.

A novel magnetically recoverable Au nanocatalyst was fabricated by spontaneous green synthesis of Au nanoparticles on the surface of gum arabic-modified Fe3O4 nanoparticles. A layer of Au nanoparticles with thickness of about 2 nm was deposited on the surface of gum arabic-modified Fe3O4 nanoparticles, because gum arabic acted as a reducing agent and a stabilizing agent simultaneously. The resu...

This communication reports a nanocatalyst-based electrochemical assay for proteins. Ultrasensitive detection has been achieved by signal amplification combined with noise reduction: the signal is amplified both by the catalytic reduction of p-nitrophenol to p-aminophenol by gold-nanocatalyst labels and by the chemical reduction of p-quinone imine to p-aminophenol by NaBH4; the noise is reduced ...

lighvan cheese is one of the most popular iranian cheeses that always faces to microbial problems due to traditional ways of production. in this study the effect of two types of low density polyethylene-nanocamposite films contains of ag, cuo and zno nanoparticles with different percentage increasing the shelf-life of chesse in 4̊c was investigated. microbial tests of the packed cheeses were don...

The present study reports for the first time the use of a thiol-functionalized graphene oxide nanocatalyst with impressive activity (>10(5)-fold) in dephosphorylation reactions. The innovative and recyclable nanocatalyst has potential in designing artificial enzymes with targeted multifunctionalities and in detoxification of organophosphorus agents.

In this study, we aimed to observe how different operating parameters influenced the photocatalytic degradation of rhodamine B (RhB, cationic dye) and bromophenol Blue (BPB, anionic over ZnO/CuO under visible light irradiation. This further corroborated optimization study employing response surface methodology (RSM) based on central composite design (CCD). The synthesis nanocomposite was carrie...
