Study on the Preparation and Optical Properties of Graphene Oxide@FeO Two-Dimensional Magnetically Oriented Nanocomposites.

In this work, graphene oxide@Fe3O4 (GO@Fe3O4) two-dimensional magnetically oriented nanocomposites were prepared through the co-precipitation approach using graphene oxide as the carrier and FeCl3·6H2O and FeSO4·7H2O as iron sources. The samples were characterized and tested by X-ray diffraction, a transmission electron microscope, Fourier-transform infrared spectroscopy, a vibrating-specimen magnetometer, a polarized optical microscope, an optical microscope, etc. The effects of material ratios and reaction conditions on the coating effects of Fe3O4 on the GO surface were investigated.

The combination of starch nanoparticles and Tween 80 results in enhanced emulsion stability.

In this work, we aimed to investigate the effect of the combination of starch nanoparticles (SNPs) and Tween 80 (TW) on the stability of oil-in-water emulsions. The emulsions prepared under different SNPs/TW ratios and different oil fraction values were characterized by means of photography, optical microscopy, laser particle size analysis, rheological measurement, quartz crystal microbalance analysis, and confocal laser scanning microscopy. At an oil fraction value of 0.
