Diffusion equations with general nonlocal time and space derivatives
Chung-Sik Sin, Hyong-Chol O, Sang-Mun Kim
In the present study, firstly, based on the continuous time random walk (CTRW) theory, general diffusion equations are derived. The time derivative is taken as the general Caputo-t…
Cauchy problem for general time fractional diffusion equation
Chung-Sik Sin
In the present work, we consider the Cauchy problem for the time fractional diffusion equation involving the general Caputo-type differential operator proposed by Kochubei. First,…
Effect of orientational ordering of water dipoles on stratification of counterions of different size in multicomponent electrolyte solution near charged surface -- a mean field approach
Jun-Sik Sin, Kwang-Il Kim, Chung-Sik Sin
We theoretically studied electric double layer by using the mean-field approach including the non-uniform size effect and the orientational ordering of water dipoles in electrolyte…
Influence of asymmetric depletion of solvents on the electric double layer of charged objects in binary polar solvent mixture
Jun-Sik Sin, Chung-Sik Sin
For binary solvent mixtures composed of ions and two kinds of polar solvents, electric double layer near a charged object is strongly affected by not only the binary solvent compos…
Electric double layer of colloidal particles in salt-free concentrated suspensions including non-uniform size effects and orientational ordering of water dipoles
Jun-Sik Sin, Kwang-Il Kim, Kuk-Chol Ri +3
The response of a suspension under a variety of static or alternating external fields strongly depends on the equilibrium electric double layer that surrounds the colloidal particl…
Effect of solvent polarization on electric double layer of a charged soft surface in an electrolyte solution
Jun-Sik Sin, Nam-Hyok Kim, Chung-Sik Sin
We study the electric double layer near a charged soft surface by using a mean-field approach including non-uniform size effect and solvent polarization. Based on a free energy mod…
