A microstructure deformation of indium oxide (In2O3) nanoparticles by an in situ thermal radiation treatment in nitrous oxide plasma was investigated. The In2O3 nanoparticles were completely transformed into nanostructured In2O3 films upon 10 min of treatment time. The treated In2O3 nanoparticle sample showed improvement in crystallinity while maintaining a large surface area of nanostructure m...

SiNx and SiCxNy coatings were fabricated with high power impulse magnetron sputtering (HiPIMS). The coatings microstructure, growth pattern, surface morphology, composition, and bonding structure were investigated by AFM, SEM, GIXRD, TEM, EDS as well as XPS, and related to the deposition parameters target powers and substrate temperature. Crosssections of SiCxNy coatings showed either dense and...

Through changing the argon pressure, CaB6 films with different crystallographic orientation and morphology on glass substrates were prepared by direct current (DC) magnetron sputtering method. The film textures, crystallite sizes, composition and morphology were investigated by a spectrum of characterizing techniques in terms of X-ray diffraction (XRD), field emission scanning electron microsco...

In this study, thin layers of titanium nitride (TiN) were deposited on H13 steel substrates at different duty cycles and temperature of 520 ˚C using plasma assisted chemical vapor deposition (PACVD). Uniaxial residual stress was calculated by X-ray diffraction (XRD) and Sin2 Ψ method. Then the residual stress of the samples were measured by Grazing Incidence X-ray Diffraction (GIXRD) method and...

Ion beam modification to effect ion beam mixing without changing morphology was investigated as a means to improve the electrochemical performance of Ge thin film electrodes for rechargeable Li batteries. As a result of a minimum tenfold increase in the strength of adhesion of the Ge film to the current collector (substrate), the ion beam-mixed electrodes exhibited stable specific capacities of...

Using an endoscopic approach, small intraoral bone chambers, which are routinely obtained during tooth extraction and implantation, provide visual in vivo access to internal bone structures. The aim of the present paper is to present a new method to quantify bone microstructure and vascularisation in vivo. Ten extraction sockets and 6 implant sites in 14 patients (6 men / 8 women) were examined...

The microstructure and morphology of solid-oxide fuel-cell electrodes are very complex but important because they strongly affect the electrical performance of the cell. In this work the high-resolution X-ray nanotomography technique is applied to reconstruct the three-dimensional microstructure of a (La(0.8)Sr(0.2))(0.95)MnO(3) yttria-stabilized zirconia composite cathode. Some key microstruct...

Microstructure plays an essential role in determining the properties of crystalline materials. A widely used method to influence microstructure is the addition of nucleating agents. Observations on films formed from clay-polymer blends indicate that particulate additives, in addition to serving as nucleating agents, may also perturb crystal growth, leading to the formation of irregular dendriti...

Abstract This paper investigates the dissimilar friction stir lap welding of AA2198 and AA7075 sheets. The influence processing parameters, namely speed tool rotational on joint features, microstructure, mechanical properties were studied by implementing a full factorial design experiments. Axial transversal forces continuously measured during process using sensed fixture aiming at correlation ...
