High saturation magnetization superparamagnetic Fe/Ni core/shell microparticles for chromium removal

Low-Temperature Preparation of Superparamagnetic CoFe2O4 Microspheres with High Saturation Magnetization

Based on a low-temperature route, monodispersed CoFe(2)O(4) microspheres (MSs) were fabricated through aggregation of primary nanoparticles. The microstructural and magnetic characteristics of the as-prepared MSs were characterized by X-ray diffraction/photoelectron spectroscopy, scanning/transmitting electron microscopy, and vibrating sample magnetometer. The results indicate that the diameter...

Static and Dynamic Magnetization of Gradient FeNi Alloy Nanowire

FeNi binary nanowires with gradient composition are fabricated by the electrodeposition method. The energy dispersive spec-trometer line-sweep results show that the composition changes gradually along the wire axis. The gradient FeNi nanowires exhibit polycrystalline and crystal twinning at different areas along the nanowire axis, with a textured face-centered cubic structure. The static and dy...

Synthesis of magnetic graphene-Fe3O4 nanocomposites by electrochemical exfoliation method

Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...
