A novel polyamine microsphere, prepared from the water-in-oil emulsion of polyethylenimine, was characterized. The investigation of scanning electron microscopy showed that the polyamine microsphere is a regular ball with a smooth surface. The diameter distribution of the microsphere is 0.37-4.29 μm. The isoelectric point of the microsphere is 10.6. The… (More)
A facile method for synthesis of CdS nanoparticles has been described. Monodisperse face-centered cubic CdS NPs could be synthesized in switchable surfactant reverse micelles. The micelles could be broken easily and CdS NPs without a coating of surfactants could be obtained by bubbling N(2) at 65 °C.
