Preparation of Cobalt Oxide/Zinc Oxide Nanocomposite
Cobalt Oxide/ Zinc Oxide nanocomposite was synthesized by dropwise addition ofCo(NO)3.6H2O and Zn(NO3)2.4H2O solutions to KOH solution at different temperatures followed bycalcination at 300ºC for 4 h. The morphology and structure of nanoparticles and the influence oftemperature on particle size were studied using scanning electron microscopy (SEM) and X-RayDiffraction (XRD). Minimum particle s...
متن کاملZinc oxide and gallium doped zinc oxide nanowires for optoelectronics
Zinc oxide (ZnO) nanostructures are become an important matter of study since they can be used in nanoscale optoelectronics for applications such as memory storage, logic circuits, solid-state gas-, bioor light-sensors, solar cells, field effect transistors, field effect displays, and short wavelength light emitting diodes. ZnO is a semiconductor with a direct and wide band-gap around 3.4 eV, a...
متن کاملHydrogen loading of oxide powder particles: a transmission IR study for the case of zinc oxide.
Many hydrogenation reactions are catalyzed by metal oxides. A particularly important case is the synthesis of methanol from syngas (H2, CO, CO2). Although presently mainly ZnO-supported Cu particles are used in the technical process, ZnO alone is also active as a catalyst for this process. According to the standard model the sources for the hydrogen species in the hydrogenation reactions are hy...
متن کاملThe Effect of Zinc Oxide Scallop-Shell Powder and Complications After Coronary Angiography
Introduction: Coronary angiography is often associated with complications such as hemorrhage and hematoma that should be considered and be minimized. Objective: This study aimed to determine the effect of Zinc oxide scallop-shell powder as a topical hemostatic agent (composed mainly of calcium) on complications after coronary angiography. These complications include hemostasis time, low back p...
متن کاملZinc oxide quantum rods.
Nanoscale zinc oxide (ZnO) rods of diameters close to the Bohr-exciton radius ( approximately 2 nm) can be prepared from a simple acetate precursor, resulting in ligand-capped rods of ZnO, highly dispersible in nonpolar solvents. Zinc oxide, ZnO, is a wide band-gap semiconductor with applications in blue/ultraviolet (UV) optoelectronic devices and piezoelectric devices. We observe self-assembly...
