Origin of the effective mobility in non-linear active micro-rheology
I. Santamaría-Holek, A. Pérez-Madrid
The distinction between the damping coefficient and the effective non-linear mobility of driven particles in active micro-rheology of supercooled liquids is explained in terms of i…
Pattern formation from consistent dynamical closures of uniaxial nematic liquid crystals
Humberto Hijar, Diego Marquina de Hoyos, Ivan Santamaria-Holek
Pattern formation in uniaxial polymeric liquid crystals is studied for different dynamic closure approximations. Using the principles of mesoscopic non-equilibrium thermodynamics i…
The rheology of concentrated suspensions of arbitrarily-shaped particles
I. Santamaria-Holek, Carlos I. Mendoza
We propose an improved effective-medium theory to obtain the concentration dependence of the viscosity of particle suspensions at arbitrary volume fractions. Our methodology can be…
Improved viscosity-concentration equation for emulsions of nearly spherical droplets
Carlos I. Mendoza, I. Santamaria-Holek
We propose an improved viscosity model accounting for experiments of emulsions of two immiscible liquids at arbitrary volume fractions and low shear rates. The model is based on a…
Protein motors induced enhanced diffusion in intracellular transport
I. Santamaria-Holek, M. H. Vainstein, J. M. Rubi +1
Diffusion of transported particles in the intracellular medium is described by means of a generalized diffusion equation containing forces due to the cytoskeleton network and to th…
The rheology of hard sphere suspensions at arbitrary volume fractions: An improved differential viscosity model
Carlos I. Mendoza, Ivan Santamaria-Holek
We propose a simple and general model accounting for the dependence of the viscosity of a hard sphere suspension at arbitrary volume fractions. The model constitutes a continuum-me…
Finite-size effects in intracellular microrheology
I. Santamaria-Holek, J. M. Rubi
We propose a model to explain finite-size effects in intracellular microrheology observed in experiments. The constrained dynamics of the particles in the intracellular medium, tre…
