DOI: 10.1016/j.jmmm.2017.06.021
Abstract: Abstract Nanoparticles cobalt ferrite, vacancies defective through vanadium substitution for iron, were synthesized by a sol-gel method. Two systems CoFe2-xVxO4 (0.0 ≤ x ≤ 0.25) and CoFe2-1.67xVxO4 (x = 0.1, 0.2) were prepared. The crystal structure, microstructure and magnetic properties were… read more here.

DOI: 10.1590/0001-3765201720160519
Abstract: This study covers the evaluation of the structure and the capacity in adsorbing orthophosphate ions of kaolinites collected from sampling sites in Manaus (Brazil). The kaolinites were obtained using physical fractioning (sieving/siphoning) techniques and chemical… read more here.
