Dissipative Particle Dynamics Simulation

In this work, we investigated the crystal formation of anisotropic nanoparticles, namely Janus particles, at the water-oil interface using the dissipative particle dynamics simulation method. By considering three different interface templates, including planar, droplet, and rod, we observe an increase of the disorder-order transition packing fraction with increasing the curvature radius of the templates. Furthermore, the nanoparticles in the planar template assemble into a hexagonal lattice, while for the two remaining templates they aggregate into colloidsome-like structures.

Insight Into

A dissipative particle dynamics simulation method is used to get insight into molecular-level details of vesicle fusion in this study. For simplicity, the simulation system contains water and amphiphiles. The fusion mechanism is investigated in detail. It is found that the whole fusion process is in well agreement with the “stalk-pore” hypothesis. The dynamics of vesicle fusion is analyzed by monitoring the time evolutions of morphologies.

Dissipative Particle Dynamics Simulation

A dissipative particle dynamics simulation method is used to investigate the vesicle fusion behavior in this study, especially to probe the driving force for vesicle fusion. Based on the former study, the fusion mechanism is investigated from the point of conservative energies. It is found that the total energy is decreasing during vesicle fusion, which is mainly caused by the reduction of conservative energy. Through further exploring the six interaction energies of particle-pairs, it is demonstrated that the energy reduction is attributed to the interaction energy between water and amphiphiles. The pressure variation confirms that vesicle fusion is a process of energy releasing.
