HAAlumina nanocomposite is biocompatible and has desirable mechanical and physical properties. Less cost, simple synthesis method, and fast production are the added advantages of this nanocomposite. Thus HA coatings on the surface of alumina substrates are used to combine excellent bioactivity of HA with superior mechanical properties of the alumina substrates. One of the elements associated wi...

Oxide nanoparticles can exhibit unique physical and chemical properties due to their limited size and a high density of corner or edge surface sites. In this study, MgO nanoparticle was synthesized using Mg(CH3COO)2 and hexamethylenetetramine as starting materials. The structure and optical properties of these particles are investigated by using X-ray diffraction (XRD), sc...

In this study, the effect of preparation route of magnetic graphene oxide (mGO) on Reactive Black 5 (RB5) adsorption was investigated. The synthesis of mGO was achieved both with (i) impregnation method (mGOi nanoparticles), and (ii) co-precipitation (mGOp nanoparticles). After synthesis, the full characterization with various techniques (SEM, FTIR, XRD, DTA, DTG, VSM) was achieved revealing ma...

Mg–Cu alloy nanoparticles were in situ prepared by a physical vapor condensation method (arc discharge) in a mixture of argon and hydrogen. Four crystalline phases, Mg, Mg2Cu, MgCu2 and MgO, were formed simultaneously during the arc-discharge evaporation. Detailed experiments revealed that nanostructured hydrogen-active phases of Mg2Cu and Mg exhibit enhanced hydrogen absorption kinetics possib...

In this study, we describe the growth of carbon nanotubes on commercial iron nanoparticles without carbon shell (Fe (nm), size 2O3 and Fe* (nm)/MgO) was carried out by mixing commercial Fe* nanoparticles (as catalyst) with Al2O3 and MgO powders (as supports)by using ball-milling method. The results show in spite of the fact that ball-milling process can have neg...

Quantum antidots are subnanometer scale vacancy clusters, the localized electronic structure of which can significantly alter the properties of a nanomaterial. We use positron spectroscopy to study vacancy clusters generated during the formation of gold nanoparticles via ion implantation in an MgO matrix. We observed that quantum antidots are associated with the nanoparticle surfaces after anne...

We report on in situ studies of the vibrational properties of Si nanoparticles and ultrathin layers grown by dc magnetron sputtering in ultrahigh vacuum on amorphous MgO and Ag buffer layers. The average thickness of the Si layers ranged from monolayer coverage up to 200 Å. Transmission electron microscopy has been used to determine size and shape of the Si nanoparticles. Changes in the phonon ...

A study of the magneto-optical MO spectral response of Co nanoparticles embedded in MgO as a function of their size and concentration in the spectral range from 1.4 to 4.3 eV is presented. The nanoparticle layers were obtained by sputtering at different deposition temperatures. Transmission electron microscopy measurements show that the nanoparticles have a complex structure which consists of a...
