1.自驱动胶体体系的自组织(Self-organization in self-propelled colloids)

   自驱动胶体单元彼此独立地从环境或外场中获取能量以维持运动。在稳定能量输入的驱动下，自驱动胶体体系远离热力学平衡态，随机涨落被不断放大，最终导致系统失稳。失稳后的系统不断演化，直到形成稳定的非平衡结构。这种非平衡自组织过程在自然界是一种非常普遍的现象。从生物胚胎的发育到雪花(冰晶)的形成，从云层斑图的出现到星系螺旋结构的涌现，自然界各个尺度上都存在丰富多彩的非平衡自组织现象。自驱动胶体体系的自组织为我们了解非平衡自组织的微观动力学过程提供了窗口，为发展可控非平衡结构提供了一种实验手段。

 研究内容：

•时-空斑图的涌现 (Emergence of spatiotemporal patterns)

•集体运动的空间结构化 (Structured collective motions)

•活性晶体 (Active crystals)

2.活性体系自组织的调控(Self-organization in active matters)

  研究内容：

• 细菌集体行为的控制 （Controlled collective motions of bacteria)

• 细胞内生物过程的控制 (Controlled cellular processes)

3.胶体自组装(Colloidal self-assembly)

  研究内容：

• 多分散胶体体系的结晶 (Crystallization in polydisperse colloids)

• 晶体缺陷的扩散和相互作用 (Diffusion and reaction of crystal defects)

• 晶核的形成与生长 ( Nucleation of crystal nuclei)
