Two-dimensional colloidal fluids exhibiting pattern formation.

Segregation in the Desiccated Sessile Drops of the Biological Fluids∗

The priority in the investigation of the dehydration self-organization phenomenon in biological fluids belongs to Prof. E. G. Rapis. While seeming simple, the effect turned out to be extremely complicated and to involve a number of interrelated processes of different nature. The biological fluids are complex colloidal systems. Even the slightest variation in the composition of a liquid leads to...

Title Dynamical pattern formation in two-dimensional fluids and Landau pole bifurcation

Local-heterogeneous responses and transient dynamics of cage breaking and formation in colloidal fluids.

Quantifying the interactions in dense colloidal fluids requires a properly designed order parameter. We present a modified bond-orientational order parameter, ψ̄6, to avoid problems of the original definition of bond-orientational order parameter. The original bond-orientational order parameter can change discontinuously in time but our modified order parameter is free from the discontinuity and...

Nearest pattern interaction and global pattern formation

We studied the effect of nearest pattern interaction on a global pattern formation in a two-dimensional space, where patterns are to grow initially from a noise in the presence of a periodic supply of energy. Although our approach is general, we found that this study is relevant in particular to the pattern formation on a periodically vibrated granular layer, as it gives a unified perspective o...

Numerical study of pattern formation following a convective instability in non-Boussinesq fluids.

1 We present a numerical study of a model of pattern formation following a con-vective instability in a non-Boussinesq fluid. It is shown that many of the features observed in convection experiments conducted on CO 2 gas can be reproduced by using a generalized two-dimensional Swift-Hohenberg equation. The formation of hexagonal patterns, rolls and spirals is studied, as well as the transitions...
