“…This leads to an isotropic distribution of the residual surface charges, generating a uniform stacking of nanoparticles. In addition, it is interesting to note that the presently obtained results show obvious differences with those of the relative report of FeNi 3 nanoparticles preparation with CTAB as template [29]. In that work, the iron-nickel nanochains were formed by an orderly self-assembly process.…”

In this paper, crystalline iron-nickel alloy nanostructures were successfully prepared from two cationic pyridinium derivatives as soft templates in solution. The crystal structure and micrograph of FeNi alloy nanostructures were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy, and the content was confirmed by energy-dispersive spectrometry. The results indicated that the as-prepared nanostructures showed slightly different diameter ranges with the change of cationic pyridinium derivatives on the surface. The experimental data indicated that the adsorption of cationic pyridinium compounds on the surface of particles reduces the surface charge, leading to an isotropic distribution of the residual surface charges. The magnetic behaviours of as-prepared FeNi alloy nanostructures exhibited disparate behaviours, which could be attributed to their grain sizes and distinctive structures. The present work may give some insight into the synthesis and character of new alloy nanomaterials with special nanostructures using new soft templates.

“…Lu et al demonstrated the synthesis of FeNi 3 nanoparticles via a hydrazine reduction method without using any surfactant agent [28]. Interestingly, they have recently reported a simple cetyltrimethylammonium bromide (CTAB)-mediated directed-assembly method for the synthesis of magnetic iron-nickel nanochains in an aqueous solution [29].…”

“…The zeta potential of the colloid dispersed in a water solution depends on the surfactant added. 21 A surfactant molecule is composed of a hydrophilic part with electrical charge and a nonpolar hydrophobic part. When an anionic surfactant SDS is added as in this study, SDS molecules are repulsed from the particle surface by Coulomb force due to their negative hydrophilic part.…”

The effect of anionic and cationic surfactants on the generation of nickel nanoparticles in a liquid-phase plasma was investigated. The size and morphology of nanoparticles generated under different conditions were observed. When no surfactant was added, more and larger particles were generated under a longer plasma treatment time and a higher electrical conductivity of the solution. When an anionic surfactant SDS was added, spherical nickel nanoparticles with various sizes were generated, with no clear evidence for the effect of SDS observed. When a cationic surfactant CTAB was added, very small nanoparticles (≤ 10 nm) could be obtained with a short reaction time. When the reaction time was too long (≥ 60 minutes), larger polygonal or wisker-shaped particles were generated.

“…Li et al [15] developed magnetite particle-chain microwires by coprecipitation method under a magnetic field gradient. Also, Wang et al [16] described a hydrothermal process to prepare chains of Cobalt spheres; and IroneNickel alloy nanochains have been reported by Lu et al [17]. However those synthesis techniques are expensive and the resulting nanoparticles usually present undesired agglomeration and polydispersion in size and shape with the formation of complex structures.…”
