Shape-anisotropic particles at curved fluid interfaces and role of Laplace pressure: A computational study

- Diffuse interface field approach is adopted to model multi-liquid colloidal system.
- Gibbs-Duhem-type formalism is developed to treat heterogeneous Laplace pressure.
- Isolated anisotropic particles do not disturb uniform curvature of liquid interface.
- Interacting particles alter shape and local curvature of liquid interface.
- Morphology and stability of Pickering emulsion droplets depend on Laplace pressure.
