Recent experiments(Ouriemi & Vlahovska,2014)show intriguing surface patterns when a uniform electric field is applied to a droplet covered with colloidal particles.Depending on the particle properties and the electrical field intensity,particles organize into an equatorial belt,pole-to-pole chains,or dynamic vortices.Here we present simulations of the collective particle dynamics,which account for electrohydrodynamic flow and dipole-dipole interactions.Our results provide insight into the various particle assembles observed in the experiments.

在酸性电解液中,金属Ru有较高的氧还原催化活性,但其表面容易被氧化而降低催化活性.为了改善金属Ru的催化性能,利用机械合金化法制备的Ru-M(M=Fe,Mo,W,Sn)[1,2]等催化剂,电催化活性和稳定性均比金属Ru高.为了改进催化剂的制备工艺,本文以Ru3(CO)12和Mo(CO)6为前驱体,在1,6-己二醇溶剂中采用回流法合成了Ru-Mo催化剂.Ru-Mo催化剂以Rux簇为主相,同时形成无定

氧还原反应(ORR)是燃料电池、金属空气电池等的阴极反应，研究高效ORR催化剂及ORR过程具有重要意义。目前，贵金属Pt仍然是ORR活性最高的催化剂，然而Pt资源有限，价格高昂，亟需寻找Pt替代催化剂。在各种非Pt催化剂中，氧化钴对ORR具有较高的活性。鉴于氧化钴价态丰富，表面结构复杂，文献中较少涉及氧化钴粒径、晶相、表面结构等对ORR活性影响的研究。本工作在实现氧化钴纳米粒子粒径、晶相控制的基础
