In this study, a low-temperature synthetic approach was developed for the fabrication of calcium hydroxyapatite (CHAp) coatings on titanium substrate. The substrates were first coated with CaCO3 by spin-coating technique using sol–gel chemistry approach, and obtained product transformed into CHAp during dissolution–precipitation reaction. phase purity structural morphological features evaluated...

Barium stannate titanate (BaTi0.89Sn0.11O3, BTS11) is one of the reported lead-free materials that exhibit high dielectric and piezoelectric properties near ambient temperature. In this work, BTS11 powders were elaborated via a soft chemistry method at very low temperatures using two synthesized approaches combining sol-gel hydrothermal processes. first approach, effect barium precursor on puri...

A challenge to the simulation of Fischer–Tropsch reaction system is lack reliable kinetic models which correctly account for deviations from ideal polymerisation behaviour. The current trend in literature attribute these effects only. This ignores that reactions synthesis contain many aspects an equilibrium-controlled process. arises since rate chain growth much faster than monomer formation CO...

In this scientific research work we report a novel method to synthesis Co3O4 nanoparticles via calcinations of cobalt hydroxide which can be conveniently prepared by the Co(NO3 )2.6H2O with different reactants. In order to study the effect of calcination temperature on structure and morphology of the nanoparticles, the calcinations take place at various temperatures (at 300°C, 500°C and 700°C)....
