The purpose of this study is to register the 3D image from computed tomography (CT) and magnetic resonance (MR) and therefore to integrate the information of hard and soft tissue. The slices with maximum areas detected from both 3D data sets were used as the corresponding slices to calculate the parameters of scale, rotation and translation for 3D data(More)
Considering recent applications of electrophoresis conduced in nanoscaled devices, where particle-particle interaction can play a role, we studied for the first time the electrophoresis of two rigid spheres along their center line, taking account of the hydrodynamic, electric, and van der Waals interactions between them. Under the conditions of constant(More)
The electrical potentials of two identical planar, cylindrical, and spherical particles immersed in a salt-free dispersion are solved analytically by a perturbation approach for the case of constant surface charge density. The system under consideration simulates, for example, micelles, where the ionic species in the liquid phase come mainly from the(More)
We derived analytical expressions for the pH-regulated electroosmotic flow in a microchannel for arbitrary level of surface potential and type of electrolyte solution; previous results are almost always based on the conditions of low, constant surface potential, which are inaccurate and unrealistic. In addition, an analytical expression for the dependence(More)
A perturbation solution based on the curvature of the surface of a particle is derived for the electrical potential of two planar, cylindrical, and spherical colloidal particles immersed in a salt-free medium. Compared with the available results in the literature, the present approach improves both the accuracy and the applicable range in the level of the(More)
Adopting a Brinkman fluid model, we analyzed the electrophoresis of a charged-regulated, bi-functional particle containing both acidic and basic functional groups in a gel solution. Both the long-range hydrodynamic effect arising from the liquid drag and the short-range steric effect from particle-polymer interaction are considered. The type of particle(More)
