Room temperature co-precipitation of nanocrystalline CeO2 and Ce0.8Gd0.2O1.9-delta powder
(Elsevier B.V., 2007-04-01)
This paper describes a simple method to co-precipitate CeO2 and Ce0.8Gd0.2O1.9-delta with ammonium hydroxide from solvents such as: water, ethylene glycol, ethyl alcohol and isopropyl alcohol. Characterization by Raman ...
Templated CaCO3 Crystallization by Submicrometer and Nanosized Fibers
Electrospun submicrometer-sized poly(e-caprolactone) (PCL) meshes and nanosized multiwalled carbon nanotubes (MWCNTs) were used as a template for preparing porous and interconnected inorganic organic hybrid materials ...
Deposition and photo-induced electrical resistivity of dip-coated NiO thin films from a precipitation process
Thin films of the semiconductor NiO are deposited using a straightforward combination of simple and versatile techniques: the co-precipitation in aqueous media along with the dip- coating process. The obtained material is ...
Simple and novel strategies to achieve shape and size control of magnetite nanoparticles intended for biomedical applications
(Elsevier Science, 2016-09-05)
Monodisperse magnetite nanoparticles (MNPs) with controlled sizes and shapes were prepared. The synthesis was carried out by traditional and inverted co-precipitation method with some modifications such as presence of ...
