In this paper, lead free (K0.48,Na0.52)NbO3 (KNN(48-52)) piezoelectric ceramics were made by conventional solid state sintering process. Additives of nano ZnO (n-ZnO), nano CuO (n-CuO) and nano SnO2 (n-SnO2) were used in order to decrease the sintering temperature, as well as modifying the dielectric, piezoelectric and ferroelectric propert...

In the present paper, a gamma alumina (?-Al2O3) loaded zinc oxide (ZnO) nano-catalyst (ZnO/?-Al2O3) has been synthesized and used to accelerate removal of sulfur compounds from light gas oil by oxidative desulfurization (ODS) process. The nano-catalysts have characterized atomic force microscopy (AFM) Brunauer-Emmett-Teller (BET). ODS process conducted in batch reactor at various reaction tempe...

We were successful in growing a dense Cu film on Al2O3 substrates at room temperature using an aerosol deposition (AD) method. The characteristics of Cu films were investigated through electrical resistivity and X-ray photoelectron spectroscopy (XPS). The resistivity of Cu films was low (9.2-12.5 μΩ cm), but it was five to seven times higher than that of bulk copper. The deterioration of the re...

The photocatalytic process over semiconducting oxide surfaces has attracted worldwide attention as a potentially efficient, environmentally friendly, and low-cost method for wastewater treatment. This study presents straightforward, inexpensive, rapid route the synthesis of nickel (NiO) its composites with zinc (NiO/ZnO) copper (NiO/CuO) nanoparticles through chemical precipitation using cappin...

Open wound ulcer treatment remains a great challenge in care management especially involving multi drug resistant (MDR) pathogen. Currently, lack of effectiveness commercially available dressing material is one the primary factors delaying healing. Therefore, transformation plain Chitosan (Cs) to antibacterial polymer nanocomposite with embedment Quercetin-ZnO/CuO biocide through green synthesi...

Aim: To investigate the effect of different types nanoparticles on compressive strength (CS) and diametral tensile (DTS) type IV dental stones. Materials methods: A total 100 specimens were made from mould for all five groups. Four commercially available (aluminium oxide (Al2O3), silicon dioxide (SiO2), zinc (ZnO), zirconium (ZrO2)) used in this study a concentration 10%. CS DTS tests performed...

Abstract Growth of bionanotechnology requires functional materials, which can lower the costs and be modified to specific reaction. Conjugations nanoparticles enzymes form efficient products multi-material enzyme-nanocomplexes, controlled from synthesis application provide predicted results. Multimetallic nanooxides ZnO–CuO, ZnO–MnO, ZnO–MnO–CuO were obtained by precipitation method with sonica...

X-ray diffraction techniques have been applied to characterize the Au-catalysed growth of aligned ZnO nanowire arrays on an AlGaN/AlN/Al2O3 substrate. The orientation relationships between the AlN layer, AlGaN layer, ZnO nanowires and Au particles were determined using x-ray texture analysis. Two orientations of the Au nanoparticles, related by a 30◦ rotation about the sample normal, were obser...

Vertically aligned single crystalline ZnO nanorod arrays, approximately 3 μm in length and 50-450 nm in diameter are grown by a simple solution approach on a Zn foil substrate. CdS and CdSe colloidal quantum dots are assembled onto ZnO nanorods array using water-soluble nanocrystals capped as-synthesized with a short-chain bifuncional linker thioglycolic acid. The solar cells co-sensitized with...
