  ABSTRACT: The aggregates in sodium dedecylsulphate (SDS)/dimethylbenzene/water systems have been investigated using dissipative particles dynamic (DPD) simulation method. Through analyzing three-dimensional structures of aggregates, three simulated results are found. One is the phase separation, which is clearly observed by water density and the aggregates in the simulated cell; another is the water morphology in reverse micelle, which can be found through the isodensity slice of water including bound water, trapped water and bulky water; the third is about the water/oil interface, i. e., ionic surfactant molecules, SDS, prefer to exist in the interface between water and oil phase at the low concentration.

  ABSTRACT: Nanostructure SiO<SUB>2</SUB> was prepared from mealies corns. The micron phytoliths were obtained after treatment with mixed acids, using the phytolith samples as raw materials, nano-silica was obtained through calcining at certain temperature after boiling in the nitric solution. And its structure was characterized by X-ray diffraction (XRD), optical microscope, transmission electron microscope (TEM), scanning electron microscope (SEM), energy dispersive spectroscope (EDS) and Infrared Spectroscope (IR). The results show that the phytoliths are all dumbbellª²type in cornstalks and leaves in the micro level; however they are located along or against vertically the lignose, respectively. The nanoª²silica with diameter of 103nm is obtained through calcination after boiling in HNO<SUB>3</SUB> solution, and the nano SiO<SUB>2</SUB> crosslink in higher temperature.
