“…[21][22][23][24][25][26][27][28][29] Researchers have developed a wide range of nanocomposite materials by incorporating cobalt nanoferrite with other materials for a wide range of uses. 20 However, to the best of the authors' knowledge, this is the first time a nanocomposite of CoLa nanoferrite has been prepared with hematite. Here, nanoparticles of lanthanum, cobalt, and hematite were used to make the nanocomposite material because of their unique properties, especially their magnetic properties.…”

“…Incorporating nanocomposite materials into industry may resolve various difficulties, including biological and nonbiological challenges, as well as electronics and vehicle issues. 20 Nanocomposites are composites in which one phase has a nanoscale morphology, such as nanoparticles or nanotubes. 20 They are multiphasic because they contain multiple phases, and at least one of these phases should have a size between 10 nm and 100 nm.…”

A novel nanocomposite consisting of 0.3 cobalt lanthanum nanoferrite/0.7 lanthanum perovskite–hematite nanoparticles (CoLa/LaH) and lanthanum perovskite–hematite nanoparticles (LaH) was synthesized using a simple method. The crystallite size was determined by the X-ray diffraction (XRD) pattern, and the particle size was determined using atomic force microscopy (AFM) to demonstrate that the nano-samples had sizes within the nanoscale range. Fourier transform infrared analysis was utilized to ensure that the nano-samples were formed. By adding CoLa nanoferrite to the LaH nanoparticles, an improvement in magnetic measurements was observed. The saturation magnetization of the CoLa/LaH nanocomposite was 1.1-fold larger than that of LaH. Also, the CoLa/LaH coercivity was 1.7-fold higher than in LaH. Furthermore, the CoLa/LaH nanocomposite displayed a higher operating high frequency of 8.9 GHz, which could be used in an X-band super-high microwave frequency, than the LaH nanoparticles. The LaH nanoparticles, on the other hand, demonstrated a high operating frequency of 8.2 GHz, which could be used in the C-band super-high microwave frequency. No activity was observed for the investigated samples against the tested microorganisms, which was unexpected behavior. Therefore, the investigated nano-samples are interesting for being applied in magnetic targeting and separators, in particular the CoLa/LaH nanocomposite.

When the studied material was added to the tested microorganisms, the cell membrane of the bacteria was disrupted [39][40][41][42][43][44][45][46][47] due to the presence of toxic silver and chromium ions. Adding Ag 0.5 Cr 2.5 O 4 nanoparticles, on the other hand, had no impact on fungal germs.…”

In this work, Ag0.5Cr2.5O4 nanochromite is fabricated utilizing a simple process (flash technique) at various annealing temperatures (room and 900 °C). The particle sizes of the materials under study were shown to be in the nanoscale range by atomic force microscopy (AFM) and field emission scanning electron microscopy (FESEM). Fourier transform infrared (FTIR) analysis was performed to verify the fabrication of the examined nanosamples and evaluate the bands behavior. The tetrahedral A-site (622.9 cm−1 for room temperature, 630.6 cm−1 for 900 °C) and the octahedral B-site (557.3 cm−1 for room temperature, 563.1 cm−1 for 900 °C) were the two prominent bands measured by FTIR analysis. The elastic characteristics of Ag0.5Cr2.5O4 nanoparticles were examined using FTIR measurements, revealing that the interatomic bonding of the atoms at 900 °C is higher than at room temperature. In addition, the elastic characteristics may be understood by analyzing the transverse and longitudinal velocities. Both Gram-positive and Gram-negative bacteria were effectively inhibited by the samples evaluated for antibacterial properties; however, neither sample showed any antifungal activity. Therefore, it is highly suggested that the investigated samples could be used in different applications, particularly biological ones.

“…They are rapidly applied in industry, biological, and medical studies due to their low toxicity to the human body [11][12][13]. Moreover, Ag NPs have been more prevalent in various fabrics, keyboards, wound dressings, and biomedical equipment [14][15][16]. Because nanoscale metallic particles are unique in their ability to significantly alter biological, chemical, and physical properties due to the high ratio of surface/volume, these nanoparticles have been used for various applications [5,17,18].…”

Novel ratios of silver iron nanoparticles with the chemical formulas Ag2Fe2O4 with Ag/Fe ratio = 1/1 and Ag0.5Fe2.5O4 with Ag/Fe ratio = 1/5 were successfully synthesized using a flash auto-combustion technique at 400 oC. Structural properties were studied using XRD (X-ray diffraction), AFM (Atomic Force Microscopy), FESEM (Field Emission Scanning Electron Microscopy), and FTIR (Fourier transform infrared) analyses. The nanosize range determined from XRD analysis lies in 56.6-71.1 nm for Ag0.5Fe2.5O4 and Ag2Fe2O4 nanoparticles. The morphology was analyzed using AFM and FESEM to confirm that the particle size of both samples was spherical and nanosized with agglomeration. Fourier transform infrared (FTIR) analysis was performed to confirm nano-samples' formation. Both samples were measured using a vibrating sample magnetometer to study their magnetism. By increasing the concentration of iron ions, the saturation magnetization (Ms) increased 5-fold for Ag0.5Fe2.5O4 nanoparticles compared with Ag2Fe2O4 nanoparticles. Moreover, there is a relation between saturation magnetization and antimicrobial activity, in which high (Ms) gives high antibacterial activity. Thus, Ag0.5Fe2.5O4 had a high (Ms) and high efficacy against the tested bacteria. However, Ag2Fe2O4 showed high activity against Candida albicans. Moreover, a high-frequency application was measured from the magnetic measurements, showing that both samples could be applied at a very high frequency (VHF) in the radio wave range. Finally, both samples could be antibacterial materials, particularly Ag0.5Fe2.5O4 nanoparticles. However, Ag2Fe2O4 nanoparticles are strongly recommended for antifungal activity against Candida albicans.
