Abstract Carbon black was often used as a UV stabilizer, due to its ability absorb high-energy ultraviolet radiation. In this study, carbon added PVDF resin, and film with (PVDF/CB composite film) fabricated using precision co-extrusion casting mechanism. The properties of the films were characterized by differential scanning calorimetry (DSC), thermogravimetric analyzer (TGA), field emission e...

Abstract Nickel acetylacetonate of 0.2 M aqueous solution is used to synthesize (NiO) thin films by pulsed spray pyrolysis method onto glass substrates. Structural and morphological properties the deposited were examined using (XRD) (FESEM) techniques. The results revealed that at low substrate temperatures short time, obtained amorphous, whereas higher long time has a cubic phase. Cross-sectio...

Abstract Aluminum oxide (Al 2 O 3 ) nanoparticles are capable of improving the material characteristics if reinforced to soft and low strength material. The major limitation in utilization Al alloy 6061 medium heavy stress applications such as automobile, defense, transportations, aerospace is hardness strength. In order overcome deficiency Al6061, nano-Al Al6061 matrix nanocomposite (AMNC) was...

In this study, zinc oxide nanostructures (ZnO NS) were synthesized using Pyrus pyrifolia fruit extract. Biophysical characterization results confirmed that the materials are crystalline wurtzite ZnO structures. Field emission scanning electron microscopy (FESEM) revealed NS cubical, and sizes range 20–80 nm. Transmission (TEM) XRD a crystal lattice spacing of 0.23 nm (101) plane on NS. UV-Visib...

In this paper, we report the preparation and characterization of both the ZnO nanocrystalline thin films and nanopowder by ultrasonic spray pyrolysis technique. ZnO films were grown on polished Si(1 0 0) and amorphous glass substrates at different deposition temperature range varying from 200 to 500 1C. Both orientation and the size of the crystallites were found to depend on the substrate and ...

OBJECTIVE To investigate the repair potential of CAD/CAM (computer-aided design/computer-aided manufacturing) ceramic and composite blocks using a silane-containing bonding agent with different repair protocols. MATERIALS AND METHODS Twenty-four discs were constructed from CAD/CAM ceramic and composite blocks. The discs were divided into six groups according to surface pre-treatment employed;...

self-assembly of densely packed zno nanorods were grown on porous silicon (ps) substrate by low-temperature chemical bath deposition. the structural and optical properties of the obtained zno nanostructures on ps substrate were systematically studied. the strong and sharp (002) peak compared with other peaks in the x-ray diffraction (xrd) indicated thatzno nanorods formed with superior orientat...
