“…For the ZFO spinel ferrite sample used in this work, there were two peaks, υ 1 = 551.06 cm −1 and υ 2 = 433.67 cm −1 . These peaks are fundamental and confirm the successful formation of the cubic spinel phase in the ZFO sample [ 30 , 31 , 32 ]. The positions of the vibrational bands are listed in Table 1 .…”

Cancers are a major challenge to health worldwide. Spinel ferrites have attracted attention due to their broad theranostic applications. This study aimed at investigating the antimicrobial, antibiofilm, and anticancer activities of ebselen (Eb) and cerium-nanoparticles (Ce-NPs) in the form of ZnCexFe2−XO4 on human breast and colon cancer cell lines. Bioassays of the cytotoxic concentrations of Eb and ZnCexFe2−XO4, oxidative stress and inflammatory milieu, autophagy, apoptosis, related signalling effectors, the distribution of cells through the cell-cycle phases, and the percentage of cells with apoptosis were evaluated in cancer cell lines. Additionally, the antimicrobial and antibiofilm potential have been investigated against different pathogenic microbes. The ZOI, and MIC results indicated that ZnCexFe2−XO4; X = 0.06 specimen reduced the activity of a wide range of bacteria and unicellular fungi at low concentration including P. aeruginosa (9.5 mm; 6.250 µg/mL), S. aureus (13.2 mm; 0.390 µg/mL), and Candida albicans (13.5 mm; 0.195 µg/mL). Reaction mechanism determination indicated that after ZnCexFe2−xO4; X = 0.06 treatment, morphological differences in S. aureus were apparent with complete lysis of bacterial cells, a concomitant decrease in the viable number, and the growth of biofilm was inhibited. The combination of Eb with ZFO or ZnCexFe2−XO4 with γ-radiation exposure showed marked anti-proliferative efficacy in both cell lines, through modulating the oxidant/antioxidant machinery imbalance, restoring the fine-tuning of redox status, and promoting an anti-inflammatory milieu to prevent cancer progression, which may be a valuable therapeutic approach to cancer therapy and as a promising antimicrobial agent to reduce the pathogenic potential of the invading microbes.

“…The ionic radius of Cr (0.64 Α ° ) is smaller than Mn (0.70 A ° ). Moreover, the lattice parameters of LiCr x Mn 1−x PO 4 (x = 0.00, 0.03, 0.06, 0.1) lie in range of LiMnPO 4 46 and LiCrPO 4, 47 and also the cell parameters decrease with chromium content signifying that the lattice parameters of LiCr x Mn 1−x PO 4 follow the Vegard's law 45,48 . Although, from Figure 4A,B, the lattice parameters seemed to be constant and that somehow display the linearity of Vegard's law, however, the contraction of ionic radii can be clearly witnessed from D avg thereby with increasing the Cr concentration, the lattice contracted.…”

Summary Lithium manganese phosphate (LiMnPO4) and a series of chromium‐doped lithium manganese phosphate with variation in Cr content LiCrxMn1−xPO4 (x = 0.03, 0.06, 0.1) were prepared via conventional sol‐gel method and their dielectric properties have been explored as a function of frequency. The structure and morphology were investigated by X‐ray diffraction technique (XRD), Fourier transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. The influence of frequency upon electrical conductivity as well as di‐electric properties of the as‐synthesized LiCrxMn1−xPO4 materials have been analyzed by dielectric parameters and AC conductivity using impedance analyzer. It was observed that dielectric constant increased with frequency at lower chromium concentration while at higher chromium contents, the dielectric constant was decreased with increasing frequency. Hence, the composition with highest Cr content (ie, x = 0.1) is proved as best material for various applications owing to its lowest AC‐conductivity and lowest dielectric loss. Therefore, it is revealed that chromium doping is quite advantageous for performance of LiMnPO4 in device applications as Cr doped LiMnPO4 unveiled improved dielectric loss.

This work reports the detailed structural characterization of Zn 2+ ion-substituted cobalt ferrite nanoparticles (CFO NPs; Co 1−x Zn x Fe 2 O 4 ; x = 0.00, 0.25, 0.50, and 0.75), prepared using a facile sol-gel method. It correlates structural changes with magnetic and dielectric properties. The as-synthesized samples were investigated by X-ray diffraction (XRD) analysis, BET surface area analyzer, energy-dispersive X-ray (EDX), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), Mössbauer spectroscopy, and impedance analyzer. The pristine sample (CFO) comprised of NPs with 25 nm size, which decreased up to 11 nm upon the formation of Zn 0.75 Co 0.25 Fe 2 O 4 . The N 2 adsorption-desorption isotherm of the prepared Zn 0.5 Co 0.5 Fe 2 O 4 sample confirmed the presence of a mesoporous structure. SEM images revealed that all prepared samples exhibited porous surface with honeycomb-like structures. The cationic distribution was described by Mössbauer spectra. The increment of Zn ions in the prepared samples resulted in sharp reduction of saturation magnetization and remanence values. The normal dielectric dispersion behavior was recorded and can be ascribed to the Maxwell-Wagner type polarization. Besides, the dielectric parameters varied by increasing Zn content in CFO NPs. This may be ascribed to O 2 vacancies and Fe 3+ ions in A-and B-sites. Dielectric studies revealed that, content of Zn ions beyond x = 0.25 was sufficient to reduce both dielectric constant and loss at low frequencies.
