Abstract:

As one of the important anisotropic particles, ellipsoidal particles have widespread range of applications in biology, chemical engineering and materials. Further research on the diffusion dynamics of ellipsoidal particles not only contributes to our understanding of the diffusion dynamics of anisotropic particles, but also provides theoretical guidance for the design of materials containing anisotropic particles. Therefore, the diffusion dynamics of ellipsoidal particles has been a research focus in the diffusion of particles over 100 years and extensive theoretical, experimental and simulation studies have been conducted. Although significant progress has been made, systemic reviews on this field are rarely published up to now. In this review, we summarize the diffusion dynamics of ellipsoidal particles, including the relationship between size and diffusion properties of ellipsoidal particles under different hydrodynamic boundary conditions and the coupling effect of translational and rotational motion. Furthermore, we analyze the existing problems in this field and discuss the research trends briefly.

Key words: ellipsoidal particle, anisotropy, translational diffusion, rotational diffusion
