  • Nanoparticles tend to aggregate due to the van der Waals force, and the separation and purification of these nanoparticles are difficult in nanometer scale.In this study, we focus on the separation of two SiO2 nanoparticles attracted by van der Waals force.Assuming them as being stiffness particles in air and applying ultrasonic vibration to one of them, we analyzed and calculated the interaction and distance between the two SiO2 nanoparticles.It is found that the ratio of diameters, the amplitude, the period and the average energy density of the ultrasonic have different effects on their separation.
