The addition of Na as a promoter to Fe/HAP suppressed the formation of undesirable CH4, further improving the selectivity for light olefins and C5 hydrocarbons. Compared with Fe203, Fe/HAP showed lower CH4 selectivity (15%) and higher Cg" selectivity (45%). Meanwhile, the Fe/HAP -Na ...
The formation and characterization of the nanocomposite were performed by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR) studies. The nanocomposite was found to be very effective in the reduction ...
Thus, tremolite is the likely source of Ca for monticellite formation. These textural relationships and the thermodynamic calculations for paragenesis indicate that monticellite formed by reactions between olivine and aqueous fluids, carrying Ca released from tremolite, that were driven by a local ...
Moreover, the adsorption of uranium resulted in the formation of a monolayer on the surface of Fe2O3 and Hap/Fe2O3 samples. However, the mechanism of the process is complex, meaning that adsorption can be physical as well as chemical. In addition, it should also be emphasized that ...
Mineralization study showed the formation of apatite crystals on the FeSiHAp surface after modified simulated body fluid (m-SBF) incubation. In vitro cell growth on the FeSiHAp surface, the density of cells, the spread and production of calcium nodules on the substrate were seen to be higher...
