The isoplethal sections CaAl2O4–MgO and CaAl4O7–MgO of the Al2O3–MgO–CaO ternary system have been experimentally established at 1 bar total pressure and air of normal humidity. The sections obtained provide new data and information that are in disagreement with thermodynamic evaluations and optimizations of the Al2O3–MgO–CaO ternary system published to date. These differences arise mainly from ...

The recent discovery of perpendicular magnetic anisotropy (PMA) at the CoFeB/MgO interface has accelerated the development of next generation high-density non-volatile memories by utilizing perpendicular magnetic tunnel junctions (p-MTJs). However, the insufficient interfacial PMA in the typical Ta/CoFeB/MgO system will not only complicate the p-MTJ optimization, but also limit the device densi...

Transparent conducting oxides (TCO) offer the uncommon functional combination of being both transparent and electrically conductive. For this reason, study is concerned with preparation triple heterojunction consisting magnesium oxide, alumina, ITO using a pulsed laser deposition method intensity 3 J. Alumina bulk pellets in propanol were irradiated (Nd:YAG) at wavelength 1064 nm. Laser ablatio...

The chemical nature of the different interfaces and possible segregation effects are studied in fully epitaxial Fe/MgO/Fe s001d oriented heterostructures fabricated by combined sputtering plus laser ablation deposition techniques. Auger electron spectroscopy depth profiling experiments showed that the interfaces of the MgO spacer with the Fe layers are different, the inner MgO/Fe being spatiall...

Polymer composite of heat cure acrylic (PMMA) matrix reinforced with different weight nanoparticles Hydroxyapatite and Magnesium Oxide (1, 5 10% wt.) were prepared by hand molding technique. The oxide synthesized Simple Chemical Method (Co-precipitation). structure morphology properties MgO examined X-ray diffraction (XRD), Field Emission Scanning electron microscopy (FESEM) EDX. Lattice consta...

objective(s): so far, extensive research has been conducted on the preparation and characterization of nano ceramics based on ca-si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (ma). the aim of this study was the preparation of akermanite nano powder by mechanical activation method and bioact...
