“…An additional advantage of these magnetic materials concerns their use in hazardous conditions, such as encountered in irradiated zones. Magnetic particles are usually composed of a magnetic core to ensure a strong magnetic response and a polymeric shell to provide favorable functional groups for sorption applications [ 13 , 14 , 15 , 16 , 17 ]. Alternatively, the magnetic core can be directly decorated with reactive groups through spacer arms [ 18 ].…”

Cysteine-functionalized chitosan magnetic nano-based particles were synthesized for the sorption of light and heavy rare earth (RE) metal ions (La(III), Nd(III) and Yb(III)). The structural, surface, and magnetic properties of nano-sized sorbent were investigated by elemental analysis, FTIR, XRD, TEM and VSM (vibrating sample magnetometry). Experimental data show that the pseudo second-order rate equation fits the kinetic profiles well, while sorption isotherms are described by the Langmuir model. Thermodynamic constants (ΔG°, ΔH°) demonstrate the spontaneous and endothermic nature of sorption. Yb(III) (heavy RE) was selectively sorbed while light RE metal ions La(III) and Nd(III) were concentrated/enriched in the solution. Cationic species RE(III) in aqueous solution can be adsorbed by the combination of chelating and anion-exchange mechanisms. The sorbent can be efficiently regenerated using acidified thiourea.

“…There are numerous magnetic materials, in which the Fe 3 O 4 is of great interest due to its non-toxic characteristic, low cost and strong magnetic response. At present, there are many methods for the synthesis of Fe 3 O 4 such as co-precipitation method [28][29], solution casting technique [30], template method [31] and so on [32]. In this work, we reported a kind of recyclable, environmentally friendly and highly selective oil-absorbent materials based on core-shell structure for removing oils from water surface.…”

“…Various kinds of nanofillers, such as carbon nanostructures [ 1 ], metallic [ 2 ], and semiconducting nanoparticles [ 3 ], are selected to incorporate into polymer matrices for creating functional nanocomposites with hybrid properties. In particular, magneto-polymer nanocomposites have attracted a great attention due to their multifunctionality for a variety of applications, ease of processability and potential for large-scale manufacturing [ 4 , 5 , 6 , 7 , 8 ].…”

We report on the fabrication of desired magneto-photonic devices by a low one-photon absorption (LOPA) direct laser writing (DLW) technique on a photocurable nanocomposite consisting of magnetite (normalFe3normalO4) nanoparticles and a commercial SU-8 photoresist. The magnetic nanocomposite was synthesized by mixing normalFe3normalO4 nanoparticles with different kinds of SU-8 photoresists. We demonstrated that the degree of dispersion of normalFe3normalO4 nanoparticles in the nanocomposite depended on the concentration of normalFe3normalO4 nanoparticles, the viscosity of SU-8 resist, and the mixing time. By tuning these parameters, the most homogeneous magnetic nanocomposite was obtained with a concentration of about 2 wt % of normalFe3normalO4 nanoparticles in SU-8 2005 photoresist for the mixing time of 20 days. The LOPA-based DLW technique was employed to fabricate on demand various magneto-photonic submicrometer structures, which are similar to those obtained without normalFe3normalO4 nanoparticles. The magneto-photonic 2D and 3D structures with sizes as small as 150 nm were created. We demonstrated the strong magnetic field responses of the magneto-photonic nanostructures and their use as micro-actuators when immersed in a liquid solution.
