Supercapacitors other energy storage devices have been tungstate metal oxide because its high electrical conductivity as well low manufacturing costs. This article...

Cobalt oxide (Co3O4) nanorods were prepared by a simple co-precipitation method using ethanol solution of cobalt nitrate as precursor and cetyl trimethylammonium bromide (CTAB) as surfactant. Morphological properties of the nanoparticles were characterized. XRD measurement exhibited the structure of Co3O4 nanocrystals for annealed samples. The SEM ima...

Gd2O3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. First, Gd(OH)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (PC) mode. The deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. The electrodeposited precursor was the...

Abstract High quality recording of neuronal activities and electrical stimulation require neurotechnical implants with appropriate electrode material. Iridium oxide (IrOx) is an excellent choice material due to its biocompatibility, low electrochemical impedance, superior charge injection capacity, corrosion resistance, longevity, stability. Plasma enhanced atomic layer deposition (PE-ALD) a su...

ZnO nanoparticles have been prepared by a simple method in a short period of time. In this synthetic method, the sample was obtained using Zn(CH3COO)2·2H2O and a new template of hexamine salt. Their crystalline structure and morphology were studied by XRD and SEM. The optical properties of the sample were studied by UV–visible spectroscopy. The absorption spectr...

Hydrothermal synthesis of nickel-chitosan hybrid  has  been accomplished using Ni(CH3COO)2,4H2O, chitosan and water as starting material, template and solvent respectively, followed by calcination at 800 and 900˚C to provide nanoporous NiO800  and NiO900. The solid products were characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption, scanning electron microscopy (SEM) and Four...

RATIONALE Nitric oxide formation is deficient in airways of patients with cystic fibrosis (CF). Since nitric oxide has bronchodilatory effects, nitric oxide deficiency may contribute to airway obstruction in CF. OBJECTIVES We reasoned that inhalation of l-arginine, the precursor of enzymatic nitric oxide formation, could improve airway nitric oxide formation and pulmonary function in patients...

Zirconium oxide has found extensive applications in various industries becauseof its excellent properties such as high strength; high-temperature resistance;extraordinary wearing resistance; ionic conductivity; and corrosion resistance. Also, someProperties like high melting point, high mechanical and thermal strength, high dielectricconstant and low conductivity have in...

Here preparation of high surface area activated reduced graphene oxide (arGO) oxidized into a 3D analogue defect-rich GO (dGO) is reported. Surface oxidation arGO results in carbon to oxygen ratio C/O = 3.3, similar the state while preserving BET about 880 m2 g?1. Analysis shows abundance functional groups which converts hydrophobic precursor hydrophilic material. High carbons provide whole for...
