Preparation and characterizations of SiO2-coated nanoparticles of Mn0.4Zn0.6Fe2O4

Micro-structural investigations and paramagnetic susceptibilities of zinc oxide, europium oxide and their nanocomposite

“…The details of co-precipitation method were described in our earlier papers [43][44][45][46]. The precursor materials for the preparation of the batch-I sample were zinc nitrate hexahydrate (Zn(NO 3 ) 2 Á 6H 2 O), triethanolamine (TEA) and HNO 3 .…”

XRD, HRTEM, magnetic and Mössbauer studies on chemically prepared Fe3+-doped nanoparticles of cerium oxide

“…The stirring is continued for about 2 h at about 50 1C. Finally, the precipitated particles are dried at 60 1C for 24 h. The details of sol-gel preparation is reported in our earlier papers [22,23]. The as-dried samples are annealed in air at various temperatures from 300 to 1000 1C to obtain the samples with different particle sizes.…”

Comparison of surface effects in SiO2 coated and uncoated nickel ferrite nanoparticles

“…Sol-gel, co-precipitation, inert gas condensation, microemulsion, etc., are commonly used methods to coat nanoparticles for surface modification [13][14][15]. Among them, sol-gel process is a simple chemical method, which has been extensively used for the coating of different nanoparticles with SiO 2 layer [6,12,16]. Magnetic properties of the nanoparticles can also be influenced by preparation technique, preparation conditions, interparticle interactions, particle shape and particle size [17].…”
