RISBiosynthesis of Superparamagnetic iron oxide nanoparticles (SPIONs) by Bacillus safensis MN18 isolated from the Caspian Sea
Introduction: Superparamagnetic iron oxide nanoparticles due to their unique features, are one of the mostly used nanoparticles in the fields of biotechnology and medicine. The aim of this study was to facile biosynthesis ...
Effect of alumina percentage on size and superparamagnetic properties of Ni-Al2O3 nanocomposite synthesized by solution combustion
This paper investigates a method to achieve a close to superparamagnetic behavior in Ni-Al2O3 nanocomposite synthesized by solution combustion. The starting materials used are nickel and aluminum nitrates, as oxidizers, ...
Stability and magnetization of Fe3O4/water nanofluid preparation characteristics using Taguchi method
scattering methods (DLS) distribution and transmission electron microscopy (TEM) images are applied in nanoparticle size
investigation. Two-step preparation method is used to prepare the ferrofluid samples. Zeta potential and vibrating sample
magnetometer (VSM...
Synthesis, characterization and first application of keggin-type heteropoly acids supported on silica coated NiFe2O4 as novel magnetically catalysts for the synthesis of tetrahydropyridines
characterized by several methods (FT-IR, SEM, TEM,
VSM, XRD, BET and ICP-AES), and the catalytic activities of these new and magnetic catalysts in synthesis of tetrahydropyridine derivatives have been investigated. These new catalysts showed that they can...
