“…The magnetic properties of the investigated samples have been illustrated in detail in previous studies. [33][34][35][36] It can be seen that AgFeO 2 delafossite had a strong switching field distribution more than 9fold that of AgCrO 2 delafossite. This may be due to the strong magnetic interaction of the AgFeO 2 cations.…”

“…Moreover, flash autocombustion used to prepare AgFeO 2 and AgCrO 2 delafossite is simple and low-cost, which can have potential applications in electromagnetic composites. [29][30][31][32] In addition, the characterization of the investigated samples has been discussed in detail in previous literature [33][34][35][36] to assure their formation. Finally, the novelty of the present work is the illustration of the elastic properties estimated from FTIR analysis, as well as the optical properties of AgFeO 2 and AgCrO 2 delafossite.…”

Nanometric AgFeO2 and AgCrO2 delafossite were easily prepared by the flash auto-combustion method. The two main bands estimated from FTIR (Fourier-transform infrared) analysis were the tetrahedral A-site (573 cm−1 for AgFeO2, 630 cm−1 for AgCrO2) and the octahedral B-site (484 cm−1 for AgFeO2, 595 cm−1 for AgCrO2). This study is mainly focused on the elastic properties evaluated from the FTIR analysis and showed that AgCrO2 delafossite is more elastic than AgFeO2 delafossite. The elastic properties can be explained by studying the longitudinal and transverse velocities. Owing to the optical properties results, AgCrO2 delafossite is a promising material to be applied in optical devices. However, AgFeO2 delafossite is a promising material in magnetic applications because it showed a large switching field distribution by 9-fold more than that of AgCrO2 delafossite. Moreover, high-frequency applications were calculated from the magnetic analysis and showed that both samples could be applied in ultra-high microwave applications.

“…The physical, structural, and magnetic properties of most of the investigated nanometric delafossite were reported in previous literatures in details [25,27,28,[32][33][34]. Crystallite and particle sizes were obtained by using field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) ( Table 7).…”

“…Doping silver nanoparticles to form important compounds that can be applied in many fields as magnetic targeting, separators, cancer diagnosis, antimicrobial activities, water treatment, and biomedical applications [19][20][21][22][23][24][25][26][27]. The combination of the monovalent silver nanoparticles and the trivalent chromium, iron, or aluminum ions has many applications, especially as antimicrobial compounds [28][29][30][31][32][33][34][35][36]. From previous studies AgFeO 2 , AgAlO 2 , and AgCrO 2 nanometric delafossite showed interesting physical properties that can be applied as antimicrobial compounds [37][38][39].…”

Antibiotics and other antimicrobial compounds are the backbone of clinical medicine. Antimicrobial resistance can cause serious diseases to man. Nanotechnology can improve therapeutic potential of medicinal molecules and related agents. Widespread application of antibiotics and other antimicrobial compounds led to development of multidrug-resistant microbes, so there is need to develop novel therapeutic agents. Novel synthesized nanometric delafossite was assayed against two Gram-positive bacteria (Staphylococcus aureus and Micrococcus luteus), two Gram-negative bacteria (Escherichia coli and Klebsiella pneumoniae), four opportunistic fungi (Aspergillus flavus, A. fumigatus, A. niger, and Fusarium solani), and four Candida species (C. albicans, C. parapsilosis, C. krusei, and C. tropicalis) using diffusion assay method. The minimum inhibitory concentration (MIC) of the novel synthesized nanometric delafossite was determined using the dilution method. The assayed compounds showed different degrees of antifungal and antibacterial activities, depending on the annealing temperature of preparation of these compounds. Compounds prepared at room temperature showed greater antimicrobial activities than those prepared at higher temperatures. The antimicrobial activity depends also on the susceptibility of the test microbe.

“…The photocatalysis process is currently being highly studied because it is a simple process to be applied, a compound used in this process is titanium dioxide (TiO 2 ), which is a semiconductor non-toxic, low cost and stable, its energy GAP to the anatase phase is in the range of 3.2 eV, thus an energy range that corresponds to UV light. [13][14] To improve the efficiency and application of the TiO2 photocatalytic it is attractive that the semiconductor is distributed in polymeric nanofibers to increase its surface area. The most common technique for producing polymeric nanofibers is electrospinning, but because of its use of high electric fields, it becomes a dangerous and expensive method [15][16] .…”

This study attempted to produce polymeric microfibers with low-cost and photocatalytic properties, making it possible to remedy two modern problems, plastic disposal and irregular effluent disposal, for which we used the solution blows pinning (SBS) technique to produce recycled polystyrene (PS) microfibers (recycled waste from transparent barrel pen), the use of the SBS also has good mobility for the benefit of fibers, allowing the fibers to be produced directly under the surface where intend to be used, through the SEM was found the ideal concentration to produce uniform microfibers. With the minor average diameter, FTIR analysis of the fibers showed peak characteristics of PS, demonstrating that most of the transparent barrel pen is composed of PS. The as-prepared fibers of recycled PS were incorporated into their polymer solution with a TiO2 Degussa P25 concentration of 10% (w/w) concerning the polymer mass. For the study of photocatalytic activity, the dye Rhodamine B was used as an indicator. Excellent photocatalytic activity, XRD pattern of PS and PS/TiO2-10% fibers showed PS and TiO2 in two phases, anatase and rutile.
