Cracks in a colloidal film formed by evaporation induced drying can be controlled by changing drying conditions. We show, for the first time that the crack morphologies in colloidal films are dependent on shape of constituting particles apart from the microstructure and particle assembly. In order to investigate the particle shape effect on crack patterns, monodispered spherical and ellipsoidal...

We study numerically two-dimensional nanoparticles with a non-regular shape and demonstrate that these particles can support many more plasmon resonances than a particle with a regular shape (e.g. an ellipse). The electric field distributions associated with these different resonances are investigated in detail in the context of near-field microscopy. Depending on the particle shape, extremely ...

The effects of particle shape on settling behavior sand particles under the influence gravity in an initially quiescent water environment have been studied by a two-dimensional high-resolution numerical experiment. method is based immersed boundary method. accuracy code well demonstrated against experimental data fluttering rectangular plate. either elliptical or size about 1 mm, and aspect rat...
