“…According to the authors' knowledge, no previous study has been conducted on the elastic properties of Ag 0.5 Cr 2.5 O 4 nanochromite. It is reported from our previous work that silver chromite with the chemical formula Ag 2 Cr 2 O 4 nanoparticles with the ratio of Ag/Cr ion (1:1) at room temperature is stronger than Ag 2 Fe 2 O 4 nanoparticles with the ratio of Ag/Fe ion (1:1) [20]. Also, when comparing silver chromite with different chemical formulas AgCrO 2 with the ratio of Ag/Cr ion (1:1) at room temperature gave high strength than AgFeO 2 with the ratio of Ag/Fe ion (1:1) [21].…”

“…The authors also studied the mechanical properties of the investigated material with increasing temperature. Thus, the authors study the mechanical properties of silver chromite by increasing the chromite concentration (Cr 2.5 ) at the expense of decreasing silver ion concentration (Ag 0.5 ) with the ratio of Ag/Cr ion (1:5) compared with previous work (Ag 2 Cr 2 O 4 and AgCrO 2 ) with the ratio of Ag/Cr (1:1) [20,21]. Moreover, the authors studied the effect of the investigated samples with various temperatures, and they found that by increasing the annealing temperature, the elasticity of the nanosample increased.…”

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.

“…The atomic force microscopy (AFM) images of Ag 0.5 Fe 2.5 O 4 and Ag 2 Fe 2 O 4 nanoparticles are shown in figures 3(a)-(d). The morphology is agglomerated owing to the lack of surfactant throughout the manufacture [27][28][29][30]. Figures 4(a)-(d) depicts the investigated samples' average particle size and surface roughness, and table 1 lists their values.…”

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.

“…Diamagnetic silver nanoparticles (Ag) are more effective in the nanoscale range and are known for their antiviral, anticancer, and antibacterial activities [7][8][9][10][11]. They are also used in water purification, biosensing, and optoelectronics devices [12][13][14]. Moreover, it is reported that the strongest magnetic material in the transition metal oxides is magnetite [15].…”

Different magnetic materials of spinel copper and cobalt nanoferrites added to silver–magnetite nanoparticles were fabricated by a facile, low cost, and rapid auto-combustion method to form a nanocomposite. X-ray diffraction patterns and atomic force microscopy were studied for the investigated samples and confirmed their nanosize range. Adding cobalt nanoferrite to silver–magnetite (CoAF) yielded a more pronounced effect in the magnetic measurements than adding copper nanoferrite (CuAF). This result was attributed to the much higher coercivity Hc and saturation magnetization Ms (5.7-fold and 2.8-fold, respectively) of CoAF than CuAF; accordingly, the CoAF nanocomposite can be applied to a permanent magnet. Next, the operating frequencies of the nanocomposites were calculated from the magnetic measurements. The CoAF and CuAF nanocomposites were applicable in the microwave super-high-frequency C-band and the microwave super-high-frequency S-band, respectively. Both nanocomposites were ineffective against the tested fungi but showed strong antimicrobial activities against the tested Gram-positive and Gram-negative bacteria. Thus, CoAF and CuAF nanocomposites are potential antibacterial nanomaterials for biomedical applications.
