With the proposal by H.E. Stanley and coworkers and the late G.W. Robinson and his coworkers that liquid water exists as two rapidly exchanging microdomains of different densities, the already complex living cell has acquired new levels of complexity. Microdomains are apparently of the order of...

In the framework of SOS models, the dynamics of isolated and pairs of surface steps of monoatomic height is studied, for step–edge diffusion and for evaporation kinetics, using Monte Carlo techniques. In particular, various interesting crossover phenomena are identified. Simulational results...

We consider a region bounded by two conductors held to a constant voltage bias, one of them with an irregular rough shape and the other being a flat one. The irregular profile can be either a curve with a formation rule or the result of a deposition process. The rough shape of the profile...

Some rigorous results are reported which concern the microscopic theory of wetting. A recent new study on a generalized Young's equation for the case of rough and heterogeneous substrates is also described.

Equilibrium wetting phase transitions and critical phenomena are discussed from a phenomenological point of view. The ubiquitous character of the wetting phase transition is illustrated through its occurrence in a variety of condensed matter systems, ranging from classical fluids to...

An amphiphilic Lattice–Boltzmann approach is adopted to model dynamic interfacial tension due to non-ionic surfactant. In the current system, the surfactant adsorption kinetics is diffusion dominated and the interface separates two immiscible fluids. A rotational relaxation time and a...

The width of the diffusion front originated by the random motion of particles under a concentration gradient is evaluated by means of Monte Carlo simulations. It is found that the roughness exponent of the front exhibits a systematic dependence on the sample size that can be rationalized in...

We study the interface of a recently introduced multilayer contact process. In this model the mean value n of the height of its interface depends on time t and on parameter p related with evaporation and deposition of particles (0⩽p⩽1). For p1cpp2c,n reaches finite non trivial values in the...
