Tuning dipolar magnetic interactions by controlling individual silica coating of iron oxide nanoparticles

Non-Supported Nickel-Based Coral Sponge-Like Porous Magnetic Alloys for Catalytic Production of Syngas and Carbon Bio-Nanofilaments via a Biogas Decomposition Approach

“…Bimetallic alloys have been synthesized using various physical and chemical techniques, including sol–gel [21], hydrothermal [22], pyrolysis [23], sonochemical [24], radiolysis [25], microwave combustion [26], microemulsion [27], impregnation [28], and precipitation [29]. However, investigation of the synthesis of bimetallic magnetic alloys is still attractive to researchers [30,31,32,33].…”

Hybrid magneto-luminescent iron oxide nanocubes functionalized with europium complexes: synthesis, hemolytic properties and protein corona formation

“…Likely, this occur due to the surface step of ligand exchanging, which may in turn destabilize the colloid and cause agglomeration of the particles due to their magnetic nature. 44 The surface functionalization of IONCs@SiO 2 nanoparticles was performed through covalently anchoring with the thenoyltrifluoroacetone-propyl-triethoxysilane moiety to give IONCs@SiO 2 -TTA. This is provided a platform to add the Eu 3+ ion to the NPs surface via metal-ligand interaction, leading to formation of IONCs@SiO 2 -TTA-Eu.…”

“…Thus, the functionalization of the surface with SiO 2 allows dispersion of the compounds in aqueous media, avoids aggregation, improves colloidal stability, decreases toxicity and increases the biocompatibility of the resulting nanomaterials. [42][43][44] The hemolytic assay is a simple, fast and robust in vitro bioassay to screening the biocompatibility/toxicity of nanomaterials. This bioassay is considered an useful tool to probe the influence of nanomaterial surface chemistry on red blood cells (RBCs), because the cell membrane disruption is easily detected by free hemoglobin released from RBCs (hemolysis) following the interaction with nanomaterials.…”

Dipolar interactions among magnetite nanoparticles for magnetic hyperthermia: a rate-equation approach

“…The existence of a finite cut-off length of dipole-dipole interaction in nanoparticle assemblies has been inferred from numerical simulations [95,96,43] and measurements [97,98]. In particular, it has been suggested that the effect of interactions is quickly reduced with increasing interparticle distance and becomes almost negligible for separations exceeding about three particle diameters.…”
