This paper describes the synthesis of paramegnetic iron-containing hydroxyapatite nanoparticles and their increased Cu(2+) sorbent capacity when using Ca(2+) complexes soluble bioorganic substrates from urban wastes as precursors. A thorough characterization particles by TEM, XRD, FTIR spectroscopy, specific surface area, TGA, XPS, DLS indicates that loss crystallinity, a higher an oxygen content, formation iron phases strongly enhance adsorption hydroxyapatite-based materials. However,...

There has been a growing interest in applying nanoparticles for enhanced oil recovery. Within this context, there is need to understand the influence of factors involved formulation nanoparticle based emulsions over their properties. In contribution, functionalized SiO2 two different sizes were synthesized and used as surfactants with model oils: squalane vacuum gas oil. Factorial experiments made analyze effects particle size, water content, emulsification energy, non-additive (second third...

Janus nanoparticles have applications in many fields. Particularly, the oil industry is interested applying them for enhanced recovery. Within this context, there a need to understand influence of factors involved formulation crude type emulsions over their properties and rheological behavior. In contribution, spherical SiO 2 two different sizes were synthesized used as surfactants aqueous with model oils: namely, squalane vacuum gas oil. Factorial experiments designed made analyze effects...
