In this study, the main attempt is devoted to investigating the microstructure and electronic properties of AlCrOxN1 - x films in a wide range of oxygen concentrations from 0 to 1. These oxynitride films were deposited by pulsed DC magnetron sputtering fro ...
A technique to perform two-wavelengths digital holographic microscopy (DHM) measurements with a single hologram acquisition is presented. The vertical measurement range without phase ambiguity is extended to the micron-range, thanks to the resulting synthe ...
Oxynitride thin films, a novel class of mixed anionic solid structures, have gained an intense interest during recent years related to the unique interplay of oxygen (O) and nitrogen (N) with metals in the material structure. This matter can result in spec ...
This study investigates and models the grinding process of single crystal sapphire. Five parameters: the wheel speed, the feed speed, the vertical feed, the ultrasonic assistance and the crystallographic direction were considered via a design of experiment ...
Polycrystalline ruby (alpha-Al2O3:Cr3+), a widely used pressure calibrant in high-pressure experiments, was compressed to 68.1 GPa at room temperature under non-hydrostatic conditions in a diamond anvil cell. Angle-dispersive X-ray diffraction experiments ...
The biogeochemical alteration of an Mg-Fe orthopyroxene, reacted for 70 yr under and conditions in a desert environment, was Studied by transmission electron microscopy. For this purpose, an electron transparent cross-section of the interface between a sin ...
Using X-ray diffraction with synchrotron radiation, we have studied the pressure changes induced by laser heating on samples compressed in a diamond-anvil cell. The method has been to compare experimentally observed phase transitions of Mg2SiO4 and SiO2 po ...
Mixed aluminum-chromium oxide coatings in the form of (Al,Cr)(2)O-3 solid solutions have attracted extensive research interest during the past years due to their successful use for challenging wear applications and the comparative ease of their moderate-te ...
The influence of oxygen content on the properties of cathodic arc-deposited AlCr(OxN1-x) coatings has been studied. All samples were prepared in a nitrogen-rich mixture of N-2 and O-2 at 550 degrees C using lateral rotating arc cathodes (LARC) technology t ...
