In Vitro behavior of mechanically activated nanosized Si-Mg-doped fluorapatite

Synthesis and in vitro antibacterial study of dihydropyrano[3,2-c]chromene derivatives by nano fluoro apatite doped with Mg and Si as a cooperative catalyst

One of the important Multi-component reaction (MCRs) is the synthesis of dihydropyrano chromene derivatives by one-pot reaction. In this research, an inexpensive and effective one pot three component procedure with good yields for the synthesis of dihydro pyrano chromenes is reported. In this method, the synthesis of pyrano chromene derivatives was followed by using 4-hydroxycoumarin, malononit...

HPHT Diamond Crystallization in the Mg-Si-C System: Effect of Mg/Si Composition

Crystallization of diamond in the Mg-Si-C system has been studied at 7.5 GPa and 1800 ◦C with the Mg-Si compositions spanning the range from Mg-C to Si-C end-systems. It is found that as Si content of the system increases from 0 to 2 wt %, the degree of the graphite-to-diamond conversion increases from about 50 to 100% and remains at about this level up to 20 wt % Si. A further increase in Si c...

Mechanically Activated Combustion Synthesis of B4C-TiB2 Nanocomposite Powder

Boron carbide is one of the hardest materials. The combustion method was used to synthesize B4C-TiB2 nanocomposite powder in a B2O3-Mg-TiO2-C system. An experimental study of the formation of B4C–TiB2 nanoparticles was conducted in the thermal explosion mode. A mixture of B2O3:TiO2:Mg:C at a molecular ratio of 3:1:12:1 was chosen to obtain the B4C–TiB2. This powder mixture was milled for differ...

In Vitro Degradation Behavior of Ternary Mg-Zn-Se and Mg-Zn-Cu Alloys as Biomaterials.

In this study, the corrosion behavior of Mg-Zn-Se and Mg-Zn-Cu alloys was investigated to evaluate their corrosion behavior related to use as implantable biomaterials. The corrosion behavior of these alloys and a commercially available Mg-Zn alloy were examined using static solution electrochemical testing, dynamic solution gravimetric testing, ion leaching testing, and microscopic evaluation. ...

Mg-Free Precursors for the Synthesis of Pure Phase Si-Doped α-Ca3(PO4)2

On this paper, methods to obtain Mg-free reagents for synthesizing pure phase Sistabilized α-TCP were established. The Mg contents of synthesized reagents were considerably lower than those in commercially available reactants. Pure Si-doped (2.5 at.-% of P by Si substitution) α-TCP was obtained by solid state reaction from synthetic reagents at temperature as low as 1200°C. When commercial reag...
