Photocatalyses such as hydrogen generation from water splitting or degrading organic contaminant on photocatalysts under solar light is promising in solving current energy and environmental issues. Bismuth ferrite (BiFeO 3 ) is a newly emerging photocatalytic material in parallel with the widely used TiO 2 -based materials, and the narrow band gap (2.1-2.7 eV) of BiFeO 3 -based materials (BFO) ...

We investigate, using density functional theory, how the interaction between ferroelectric polarization and chemical structure of (001) surfaces bismuth ferrite influences surface properties reactivity this material. A precise understanding ofthe behavior ferroelectrics is necessary for their use in science applications such as catalysis well incorporation microelectronic devices. Using a model...

Composite films based on dispersions of bismuth ferrite (BiFeO3) in polyvinylidene fluoride (PVDF) matrixes were prepared the presence multiwalled-carbon-nanotubes (MWCNT), using xanthan gum (XG) as dispersant. Films by spin coating and characterized infrared spectroscopy (FTIR) electronic microscopy (SEM). SEM images showed that samples containing MWCNT XG presented a uniform morphology with h...

The reverse co-precipitation method was used for synthesis of the pure phase multiferroic BiFeO3 (BFO) nanoparticles. Influence of different pH values on the microstructure and magnetic properties of the BFO nanopowders was investigated. Thermogravimetric-differential thermal analysis (TG-DTA) technique indicated that the optimal temperature for calcination is 550°C. The phase formation and the...

We compute the bulk photovoltaic effect (BPVE) in BiFeO(3) using first-principles shift current theory, finding good agreement with experimental results. Furthermore, we reconcile apparently contradictory observations: by examining the contributions of all photovoltaic response tensor components and accounting for the geometry and ferroelectric domain structure of the experimental system, we ex...

Theoretical analysis has been carried out to establish the heat transport phenomenon of six different ferromagnetic MnZnFe2O4-C2H6O2 (manganese zinc ferrite-ethylene glycol), NiZnFe2O4-C2H6O2 (Nickel zinc ferrite-ethylene glycol), Fe2O4-C2H6O2 (magnetite ferrite-ethylene glycol), NiZnFe2O4-H2O (Nickel zinc ferrite-water), MnZnFe2O4-H2O (manganese zinc ferrite-water), and Fe2O4-H2O (magnetite fe...

The concept of a cyclotron-resonance maser (CRM) with a ferrite loading incorporated in its waveguide is proposed. The CRM interaction occurs between the rotating electron beam and the em wave propagating along a longitudinally magnetized ferrite medium. The ferrite anisotropic permeability resembles the CRM susceptibility in many aspects, and particularly in their similar response to the axial...
