Soap films at equilibrium are modeled, rather than as surfaces, regions of small total volume through the introduction a capillarity problem with homotopic spanning condition. This point view introduces length scale in classical Plateau's problem, which is turn recovered vanishing limit. approximation area minimizing hypersurfaces leads to an energy based selection principle for points physical...

The diffusion driven by the gradient of chemical potential (by Fick/Darcy law) in deforming continua at large strains is formulated reference configuration with both law and capillarity (i.e. concentration gradient) term considered actual configurations time. Static situations are analysed direct method. Evolution (dynamical) problems treated Faedo-Galerkin method, ...

A straightforward method is presented to produce catalyst particle-filled carbon nanotubes. Based on capillarity and surface tension, a simple strategy was developed to selectively fill carbon nanotubes with Fe, Co, and Ni species using a two-step method consisting of impregnation and selective washing. By chosing the impregnation and washing solution properly, metal particles are produced excl...
