Corrosion Protection Oxide Scale Formed on Surface of Fe-Ni-M (M = Al, Cr, Cu) Inert Anode for Molten Salt Electrolysis

“…The equilibrium lattice parameters, formation energies, and cohesive energies of the normal and inverse spinel compounds are listed in Table 1 [34][35][36][37][38][39]. To evaluate the structural stability, the formation energy (E form ) and cohesive energy (E coh ) of the spinel compounds were calculated as follows [40]:…”

Excellent microwave absorbing performance of biomass-derived activated carbon decorated with in situ-grown CoFe2O4 nanoparticles

“…Open composite [44][45][46] . The two deconvoluted peaks at 780.8 and 782.8 eV can be assigned to the Co 2+ ions at octahedral and tetrahedral sites 47,48 , respectively. The Fe 2p high resolution spectrum of Fe 2p shown in Fig.…”

“…The two main peaks present at 781.2 and 797 eV are attributed to the Co 2p 3/2 and Co 2p 1/2 orbitals, respectively, and satellite peaks appear at 786.8 (Co 2p 3/2 ) and 803.6 eV (Co 2p 1/2 ), confirming the presence of Co 2+ in the FAC20 composite. [44][45][46] The two deconvoluted peaks at 780.8 and 782.8 eV can be assigned to the Co 2+ ions at the octahedral and tetrahedral sites, 47,48 respectively. The Fe 2p high-resolution spectrum of Fe 2p shown in Fig.…”

Observation of dielectric dispersion and relaxation behavior in Ni2+-substituted cobalt ferrite nanoparticles

“…18 Yadav et al reported that the grain size and cation redistribution are only responsible for the dielectric, electrical, magnetic, impedance and electrical modulus spectroscopic characteristics of synthesized CoFe 2 O 4 spinel ferrite. 19 Thomas et al studied Mg 2+ -substituted cobalt ferrite nanoparticles and stated that the dielectric behavior could be explained by the Maxwell-Wagner interfacial polarization phenomenon. 20 Despite the above considerations, cation distribution, dielectric relaxation and the polarization phenomenon are the admissible facts to correlate the dielectric dispersions of the spinel ferrite.…”
