“…5(a)) having a peak height ten times lower than that of the Ag-Al sample, and being red shied in comparison to the solution containing monometallic Ag nanoparticles. It is known that the UV-vis spectra of pure Ni nanoparticles show no peaks at wavelengths >250 nm, 33,34 therefore, the signal observed here has to be attributed to the presence of Ag-Ni nanoparticles. In comparison with Ag nanoparticles for both alloys a shi of the absorption band to longer wavelength of decreased intensity is observed in accordance with reported data.…”

The wet synthesis of mono-disperse Ag, Ag-Ni, and Pd-Ag nanoparticles has been performed employing glycol solutions containing [Ag(NH 3 ) 2 ]+ and a second metal cation Mn + (M ¼ Ag, Na, Al, Ni or Pd) under microwave irradiation in a predominately electric (E-) or a predominately magnetic (H-) field. No specific effects of the microwave E-field and H-field on the rate of product formation have been observed. But the synthesis of Ag-Ni alloy particles in the E-field and the H-field resulted in products with different particle size distribution, thus possibly indicating specific field effects.

“…Depending on the nature of sample/solution, Ni particles generated an absorption edge in the UV-Vis spectral range 374-422 nm, corresponding to the surface plasmon resonance (SPR) band of nanosized Ni particles after reduction generated by Ni (II) ions [22,23]. Optimization studies for reducing agent concentration, surfactant concentration, and pH were carried out to check their effect on the peak shape to further help in the estimation of structure/morphology and size of nanoscale metal particles.…”

The present study describes the synthesis of highly active and ordered structures of nickel nanocatalysts by a facile, green, and economically viable approach. The study reveals efficient catalytic activity for the degradation of a number of toxic organic dyes, such as eosin-B (EB), rose bengal (RB), eriochrome black-T (ECBT), and methylene blue (MB). The stable ordered nickel nanostructure (Ni NSs) arrays were prepared via a modified hydrazine reduction route with unique and controlled morphologies in a lyotropic liquid crystalline medium using a nonionic surfactant (Triton X-100). Characterization and optimization studies for the fabricated Ni NSs involving their surface binding interactions, size, and morphologies were carried out using UV-Vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM).

“…The best compromise might be found in Ni, which presents a QLSPR of 2.71 and a magnetic moment of 0.61 Bohr magnetons. For that reason, the majority of magnetoplasmonic studies with single phase magneto-plasmonic NPs employ this element [56,57], albeit other alternatives has been explored [58]. For example, the magnetoplasmonic response of Ni was recently studied using a meta-surface of Ni nanoantennas in different magneto-plasmonic Kerr Effect geometries [59,60].…”

Magneto-plasmonic nanoparticles have attracted increasing attention from the scientific community due to their promising properties and high applicability. Thanks to the development of new synthesis routes, it has been possible to use this kind of nanostructures in different biomedical applications such as dual imaging, combined treatments or biodetection. However, there is still a lack of biocompatible materials with suitable magneto-plasmonic features to translate all these advances to clinical studies.
