本工作采用闪速自燃烧技术研究了纳米银铁氧体和纳米铬铁矿（Ag 2Fe 2 O2、Ag 2Cr 2 O 4）的作用。许多物理性能从不同的结构，如晶格参数的阳离子分散，氧参数，跳跃长度，和原子间距离确定的X-射线检查澄清。在抗微生物特性中，向两种样品中添加Ag对两种类型的测试细菌（革兰氏阳性和革兰氏阴性）显示出高功效;然而，它们对白色念珠菌真菌显示出中等效果。两种样品均未出现抗黄曲霉真菌的活性。从磁性角度研究了Ag 2Fe 2 O 4和Ag 2Cr 2 O 4纳米粒子的开关场和高频响应。与Ag 2Fe 2 O 4相比，Ag 2Cr 2 O 4纳米颗粒有望用于高频应用。作为所有先前的分析的结果，本研究的应用促进了Ag 2Fe 2 O 4纳米铁氧体和Ag 2Cr 2 O 4纳米铬铁矿作为抗菌纳米材料用于高频、开关场和生物医学应用。
In this work, the effects of silver nanoferrite and nanochromite (Ag2Fe2O2, Ag2Cr2O4) were studied using the flash auto-combustion technique. Numerous physical properties were clarified from the different structures determined from the x-ray examination such as lattice parameter the cation dispersion, oxygen parameter, hopping length, and interatomic distance. Among antimicrobial properties, Ag addition to both samples showed high efficacy against both types of tested bacteria (gram-positive and gram-negative); however, they showed moderate effect against Candida albicans fungus. No activity appeared against Aspergillus flavus fungus for both samples. The switching field and high-frequency response of Ag2Fe2O4 and Ag2Cr2O4 nanoparticles were studied from the magnetic properties. Ag2Cr2O4 nanoparticles are expected to be used for high-frequency applications more than Ag2Fe2O4 ones. As a result of all previous analyses, the applications of this study promote the use of Ag2Fe2O4 nanoferrite and Ag2Cr2O4 nanochromite for high-frequency, switching field, and biomedical applications as antimicrobial nanomaterials.
