Simulation of self-assembly in an evaporating droplet of colloidal solution by dissipative particle dynamics

- Dissipative particle dynamics (DPD) is adapted to self-assembly in evaporating drop.
- DPD allows investigating in a detail the ordering of colloids in evaporating droplet.
- We take in account particle adhesion, wetting, and roughness of substrate, etc.
- Coffee ring effect is a result of compensative flow, low roughness and adhesion.
- Domains can be formed as result of interparticle repulsion and capillary compression.
