Oriented attachment has created a great debate about the description of crystal growth throughout the last decade. This aggregation-based model has successfully described biomineralization processes as well as forms of inorganic crystal growth, which could not be explained by classical crystal growth theory. Understanding the nanoparticle growth is essential since physical properties, such as t...

In the present work, thermochemical water splitting with siliconized silicon carbide (SiSiC) honeycombs coated with a zinc ferrite redox material was investigated. The small scale coated monoliths were tested in a laboratory test-rig and characterized by X-ray diffractometry (XRD) and Scanning Electron Microscopy (SEM) with corresponding micro analysis after testing in order to characterize the...

Magnetic nanoparticle composite with a cobalt ferrite (CoFe2O4, (CF)) core and an apatite (Ap) coating was synthesized using a biomineralization process in which a modified simulated body fluid (1.5SBF) solution is the source of the calcium phosphate for the apatite formation. The core-shell structure formed after the citric acid-stabilized cobalt ferrite (CFCA) particles were incubated in the ...

Cobalt manganese ferrite nanoparticles have application potential in the biomedical field, however there is limited information concerning the biological response. The aim of this work was to investigate the cytotoxic potential of cobalt-manganese ferrite nanoparticles in canine mastocytoma tumor cells (C2) and adipose-derived mesenchymal stromal stem cells (ASCs) cultured under a static magnet...

Magnetic permeability data of cobalt ferrite and carbonyl iron suspensions are discussed. Using an induction method, the relative differential permeability, mr;dif ; was measured as a function of the internal magnetic field for different volume fractions of the solid phase. In the case of cobalt ferrite suspensions, the mr;dif H curve was obtained for a first increasing ramp of magnetic field (...

The dynamic behavior of magnetic colloidal particles in suspension is investigated. The particles of the core–shell colloid consist of a cobalt ferrite core embedded in a silica shell and are stabilized by surface charges. As the suspension is strongly opaque to visible light, it can not be probed by dynamic light scattering techniques as a result of strong multiple scattering as well as absorp...

Due to their potential in numerous interdisciplinary fields, such as drug delivery, hyperthermia, and magnetic resonance imaging, nanoparticles have attracted widespread attention. In this study, cobalt ferrite are synthesized with varying amounts of iron ions, cytocompatibility is evaluated before after surface modification amino-silane (AEPTMS). Characterization the performed using scanning e...

Iron cobaltite powders CoxFe3ÿxO4 (1rxr2.46) were synthesized with compositions in between the cobalt ferrite CoFe2O4 and Co2.46Fe0.54O4. The cationic distribution of pure spinel phases was determined by Mössbauer spectroscopy: as Co content increases in the spinel oxide, Co cations replace Fe cations in the octahedral sites and Co cations migrate from octahedral to tetrahedral sites. Saturatio...

Nickel-substituted cobalt ferrite–reduced graphene oxide (NCF-RGO) composite was synthesized using a facile one-pot chemical coprecipitation method. The addition of (GO) leads to the decrease in size NCF nanoparticles (< 10 nm) present nanocomposite, which plays role controlling their magnetic and dielectric properties. Nickel with lower ionic radius compared cobalt, its substitution along inco...

The temperature variation of magnetic anisotropy and coercive field of magnetoelastic manganese-substituted cobalt ferrites CoMnxFe2−xO4 with 0 x 0.6 was investigated. Major magnetic hysteresis loops were measured for each sample at temperatures over the range 10–400 K, using a superconducting quantum interference device magnetometer. The high-field regimes of the hysteresis loops were modeled ...
