conclusions: the results showed that silver nanoparticles have an antimicrobial effect against intramacrophage b. abortus 544. results: the well diffusion agar study showed that silver nanoparticles have an antimicrobial effect on b. abortus 544. the mic and mbc of silver nanoparticles against b. abortus 544 were; 6 ppm and 8 ppm, respectively. the silver nanoparticles showed antibacterial effe...
Synthesis of YSZ nanopowder by alkoxide sol-gel method, through two different hydrolysis routes, one under careful control by using acetyacetone as ligand, and the other through basic hydrolysis, was investigated. The synthesized powders were characterized by various analytical techniques such as, XRD, STA, PSA, BET, SEM, and TEM. The results showed that, the YSZ powders prepared through the ba...
Owing to its applicability in refractory ceramic synthesis, nanoelectronics, optoelectronic and sensing devices, superconducting products, magnesium oxide (MgO) is recognized be an important material. However, it has a relatively low dielectric constant compared other metal semiconductors, which restricts the range of bandgap limits applicability. Therefore, this study, we propose verify method...
Using a pulsed electron beam evaporation in vacuum mesoporous nanopowder CaF 2 with specific surface area up to 60.5 m /g were produced. The effect of annealing different media on the evolution magnetic and texture properties nanoparticles has been studied. For first time, medium magnetization nanopowders was discovered. Keywords: nanopowders, calcium fluoride, ferromagnetism, evaporation.
