NanoparticlesExpanded graphiteSolution-free routeEnergy storage and conversionA novel Fe3O4-NPs/EG composite was prepared by a facile solution-free route.The solution-free strategy was effective to avoid restacks of the nanosheets of EG.Fe3O4-NPs with dimension <5nm were homogeneously anchored on...
The Fe 3O 4–chitosan nanoparticles with core-shell structure have been prepared by crosslinking method. Oleic acid modified Fe 3O 4 nanoparticles were firstly prepared by co-precipitation then chitosan was added to coat on the surface of the Fe 3O 4 nanoparticles by physical absorption. The ...
Surface modification of the nanoparticles of transient metals oxides (especially Fe) is essential to distribute them evenly in target solution. Moreover, in medical applications of magnetite nanoparticles, surface modification of Fe3O4nanoparticles is crucial in making them biocompatible20, so different ...

The microwave absorption properties of the octahedral Fe3O4 and gamma-Fe2O3 nanoparticles were measured in the frequency range of 2-18 GHz. A minimum reflection loss of -28 dB was observed at 8.6 GHz for octahedral Fe3O4 nanoparticles....
Fourier transform infrared (FT-IR) spectra confirmed that the YVO 4:Eu 3+ had been successfully deposited on the surface of Fe 3O 4 nanoparticles. Photoluminescence (PL) spectra indicated that the nanocomposites displayed a strong red characteristic emission of Eu 3+. Magnetic measurements showed ...
A fast and controllable synthesis method for superparamagnetic magnetite nanoparticles (Fe3O4 NPs) was developed in Fe(III)-triethanolamine (TEA) solution. The phase structure, morphology and particle size of the as-synthesized samples were characterized by X-ray diffraction (XRD) and transmission el...
