“…Figure 4b displays the saturation magnetization, remanent magnetization (M r ), and coercivity (H c ) values measured for Ag/Fe particles at 14.61 emu/g, 1.01 emu/g, and 65.35 Oe, respectively. In the case of Ag/Fe NPs, our measured values are consistent with those found in the literature [54][55][56][57]. Particles with such magnetic characteristics have a magnetic response and may be readily isolated or grouped with the help of an external magnetic field [58].…”

Magneto-plasmonic Ag/Ni and Ag/Fe nanoparticles (NPs) were synthesized in this work using the environmentally safe and contaminant-free dual-pulsed Q-switched Nd:YAG 1064 nm laser ablation method. The optical and magnetic characteristics of synthesized nanomaterials were investigated using a vibrating sample magnetometer and an ultraviolet-visible absorption spectrometer. According to transmission electron microscopy (TEM), the shape of Ag/Ni and Ag/Fe NPs seems to be spherical, with mean diameters of 7.3 nm and 11.5 nm, respectively. X-ray diffraction (XRD) was used in order to investigate and describe the phase structures of the synthesized nanomaterials. The synthesized NPs reached maximum temperatures such as 48.9, 60, 63.4, 70, 75, and 79 °C for Ag/Ni nanofluid and 52, 56, 60, 68, 71, and 72 °C for Ag/Fe nanofluid when these nanofluids were subjected to an NIR 808 nm laser with operating powers of 1.24, 1.76, 2.36, 2.91, 3.5, and 4 W, respectively. Because of the plasmonic hyperthermia properties of nanoparticles, nanofluids display higher temperature profiles than pure water. According to these findings, plasmonic nanoparticles based on silver might be used to treat hyperthermia.

“…This would be beneficial both environmentally and economically, as less material would be necessarily dispersed into water sources in order to remove contamination, and less raw material would be needed to perform contaminant removal. A similar observation may be made for the catalytic nanomaterials reported that could serve to degrade contaminants either singly or in the presence of oxidizing agents such as hydrogen peroxide [37] and oxygen [105] or reducing agents such as borohydride [139,141]. 2We see an increasing usage of biological materials, both processed and unprocessed, in the generation of novel nanocomposite materials.…”

“…The addition of magnetic nanoparticles aids this application as recovery and reuse can be facilitated. The formation of hollow porous Fe 3 O 4 microspheres (average size, 200 nm) to which silver nanoparticles were grafted was reported by Zhang et al [141] who used a hydrothermal method after the reduction of silver nitrate by sodium borohydride or tri sodium citrate. These nanocomposites were examined for the catalytic reduction of p-nitroaniline and were found to promote near complete reduction in less than 10 min in an excess of borohydride with a first-order rate constant of 0.45 min −1 , a value that compares well to the literature.…”

Water resources are of extreme importance for both human society and the environment. However, human activity has increasingly resulted in the contamination of these resources with a wide range of materials that can prevent their use. Nanomaterials provide a possible means to reduce this contamination, but their removal from water after use may be difficult. The addition of a magnetic character to nanomaterials makes their retrieval after use much easier. The following review comprises a short survey of the most recent reports in this field. It comprises five sections, an introduction into the theme, reports on single magnetic nanoparticles, magnetic nanocomposites containing two of more nanomaterials, magnetic nanocomposites containing material of a biologic origin and finally, observations about the reported research with a view to future developments. This review should provide a snapshot of developments in what is a vibrant and fast-moving area of research.
