In situ formation, structural, mechanical and in vitro analysis of ZrO2/ZnFe2O4 composite with assorted composition ratios

l-Methionine-Zr complex supported on magnetic ZnFe2O4 as a novel, green, and efficient heterogeneous magnetic nanocatalyst for the synthesis of 1H-tetrazole and polyhydroquinoline derivatives

“…An increase in the binding energy of Fe 2p 3/2 in ZnFe 2 O 4 compared with Fe 2 O 3 is attributed due to the different oxygen environment of Fe 3+ when exposed to Zn 2+ . 59,61 The O 1s and N 1s spectra show a single peak at energies of 487.48 and 530.93 eV, respectively, indicating the identical chemical environments for all N and O atoms. The fact that both oxygen atoms within the carboxylate group have very similar environments suggests that the molecule is bound to the surface as l -methionine, and the OH group has lost the hydrogen atom (Fig.…”

“…7a). 59,60 Fe 2p core level spectra (Fig. 7b) revealed two peaks that are resolved into two doublets at 704.2, 712.3, 724.5, and 740 eV, respectively, and the shakeup satellite at 719 eV authenticated the existence of the Fe 3+ state.…”

Fabrication of Mn1Zn Fe2O4 ferrofluids from natural sand for magnetic sensors and radar absorbing materials

“…ZnFe 2 O 4 nanoparticles show ferrimagnetic behavior at room temperature and antiferromagnetic ordering below 9 K [ 38 ]. Other showed that the ZnFe 2 O 4 nanoparticles have ferrimagnetic behavior at room temperature [ 39 , 40 ]. Interestingly, the ZnFe 2 O 4 ferrofluid sample has a fractal dimension of D ~1, which is interpreted as a chain arrangement resembling a rod.…”

Design, fabrication, mechanical, and in vitro evaluation of 3D printed ZrO2 reinforced polylactide scaffolds through fused deposition modeling

“…The dried gels were ground to fine powders and heat treated at 1300 °C to obtain single phase yttria-stabilized tetragonal ZrO 2 ( t -ZrO 2 ) powders. 37…”
