A model for the formation of labyrinthine patterns by thin domains of magnetic fluids is described. The dynamics is derived variationally from an energy functional which reflects a competition between surface tension and long-range magnetic interactions. A detailed linear stability analysis for cir
A nonlinear convective instability in a layer of magnetic fluid is investigated in the presence of an applied magnetic field and temperature gradient. The stability of steady state patterns resulting from the convective instability is discussed using bifurcation theory. Rolls are found to be stable
## Abstract The fabrication of flexible surfaces with a combination of ultrahydrophobic and hydrophilic properties at alternating locations by UV NIL is reported. A new method for master fabrication based on nanoimprinting combined with photolithography is described. The master is used for a double
The wetting of glass surfaces by magnetic fluids ferrofluids is treated theoretically as a wall-induced orientational nematic ordering. The nematic coherence length of the surface stabilized ordered phase is assumed to be about a few magnetic grain sizes. In this framework the surface order paramete
