Numerical multiphysics modelling of Wick-Boiling in a crud with porosity variations to determine local Nickel Ferrite depositions within crud due to deep bed filtration
… while moving away from the walls. Local Nickel Ferrite absorption within the crud is estimated using this model and results obtained from Particle Assembly/Constrained Expansion (PACE) models. The rate of absorption of these particles is hugely affected by the non-uniformity of the porous …

Chemical vapor deposition of thin film materials for electronic and magnetic applications
… has been utilized for epitaxial growth of nickel ferrite (NiFe2O4), lithium ferrite (LiFe5O8) and barium titanate (BaTiO3) films on various lattice match substrates. For the deposition of nickel ferrite, anhydrous Ni(acac)2 and Fe(acac)3 (acac = acetylacetonate) are used as precursor …

A study of solute transport of radiolysis products in crud and its effects on crud growth on PWR fuel pin
… deposits in the form of the non-stoichiometric nickel-ferrite (FexNi3-xO4) have been observed on the Zircaloy cladding surface exposed to the subcooled boiling length of the fuel rods. The thermal processes in this layer, which result in the holdup of boron (10B and 11B), cause a larger than …

Solar thermochemical conversion of CO2 into fuels using Ni-Ferrite driven redox reactions: Thermodynamic efficiency analysis
… study examines the thermodynamic performance of nickel ferrite (NiFe2O4) as a redox material in solar thermochemical CO₂ splitting processes. To evaluate how different factors influence the efficiency of this process, a detailed thermodynamic model was created. This model looks at how variations …

Anisotropic behaviour of magneto-electric coupling in multiferroic composites
… of the direct magnetoelectric effect in textured nickel ferrite/lead zirconate titanate strain mediated bilayer composites has been studied. The magnetic layers of these samples have been crystallographically textured in planes of the form {100}, {110} and {111}. In this study, it is shown that …

Cobalt core-shell nanoparticles as precursors for cobalt-based Fischer-Tropsch synthesis catalysts
… phase and/or geometric effects. In this study, nickel ferrite (NiFe2O4) and zinc ferrite (ZnFe2O4) were chosen as core materials around which a cobalt (II, III) oxide (Co3O4) shell was grown. These ferrites were chosen due to their structural similarity to Co3O4 as this was expected to allow an …

Magnetoelectric laminated composites and devices
… materials, such as Terfenol-D or nickel ferrite. The experimental results show that Metglas based ME laminates have giant ME voltage coefficients and small required DC magnetic biases. Besides, the laminates have a good directional dependence of the magnetic field: it can only …

Complex oxides of the system Cu-Ni-Fe-O: synthesis parameters, phase formation and properties
… are the solid solutions CuxNi1-xFe2O4, the ferrites occurring in the phase triangle Cu0.5Ni0.5Fe2O4 -Cu0.9Fe2.1O4 - Cu0.5Fe2.5O4 and some copper-nickel oxide solid solutions. Three synthesis routes have been used, namely (i) the preparation and the thermal decomposition of freeze-dried …
