Abstract Spinel ferrite nanoparticles (NPs), have received a lot of attention in medical applications. Therefore, facile synthesis NPs numerous shapes and sizes using the citrate autocombustion technique was utilized this article. A series with general formula MeFe 2 O 4 [Me = nickle (Ni), calcium (Ca), strontium (Sr)] are synthesized varying average ionic radii cation disorder on A-site. The s...

(Bi0.5Na0.5)0.94Ba0.06TiO3 dense ceramics were obtained from autocombustion sol-gel synthesized nanopowders and sintered at 1050 ◦C for 1–2 h for the study of the electromechanical anisotropy. Measurement of the complex impedance spectrum was carried out on thin ceramic disks, thickness-poled, as a function of the temperature from 16 ◦C up to the vanishing of the electromechanical resonances at...

ZnAlFe1−xSmxO4 (x = 0, 0.02, 0.04, 0.06, 0.08) spinel ferrites were successfully obtained for the first time via a sol–gel autocombustion technique using citric acid as combustion/chelating agent. These materials then employed photocatalysts degradation of Evans Blue, considered herein model organic pollutant. The XRD and FTIR analysis confirmed achievement pure ferrite structures all materials...

In this work, the impact of nonstoichiometric substitution Fe3+ cations by Ni2+ ones on structural and magnetic properties Co0.5Ni0.5+xFe2−xO4 nanoferrites (0.0 ≤ x 0.4) synthesized citric autocombustion method has been investigated. The single cubic phase for samples sintered at 600 °C was verified XRD patterns FTIR spectra. crystallite size microstrain were deduced using Williamson-Hall metho...

In this study, strontium hexaferrite nanoparticles synthesized by sol–gel autocombustion method and the effect of high annealing temperature on produced nanoparticle have been studied. Powders were annealed at 1,000 1,300°C. Structural properties powders analyzed X-ray diffraction (XRD). Hexagonal structure shape SrFe12O19 from field-emission scanning electron microscope transmission figures. F...

This study is the first attempt to large-scale energy-efficient production of nanomagnetic Ni/NiO composites by using autocombustion based on leaves or extract corchorus olitorius. The as synthesized product can be characterized XRD, SEM, TEM and EDX techniques. results confirm that materials consisted entirely well crystalline Ni NiO phases. crystallinity both enhanced increasing amount Howeve...

In this study, nickel oxide–Y2O3-doped ZrO2 (NiO-YSZ) composite powder as an anode material was synthesized using a cost-effective combustion method for high-temperature solid oxide fuel cell (SOFC). Further, the effects of sintering temperatures (1200, 1300, and 1400 °C) were studied its properties in relation to SOFC performance. The prepared sintered NiO-YSZ materials characterized their sur...

The detailed structural, magnetic, and cryogenic magneto-caloric properties of chromium-substituted gadolinium iron garnet (Gd 3 Fe 5- x Cr O 12 ) nanocrystalline powders were studied using the facile autocombustion method a calcination temperature 1100 °C. X-ray diffraction pattern showed that all samples single-phase with cubic Ia3 d symmetry. field-dependent magnetization data Gd revealed fe...
