Diffusion of spherical particles in microcavities.
The diffusive motion of a colloidal particle trapped inside a small cavity filled with fluid is reduced by hydrodynamic interactions with the confining walls. In this work, we study these wall effects on a spherical particle entrapped in a closed cylinder. We calculate the diffusion coefficient along the radial, azimuthal, and axial direction for different particle positions. At all locations t...
متن کاملSingle-file diffusion of macroscopic charged particles.
In this paper, we study a macroscopic system of electrically interacting metallic beads organized as a sequence along an annulus. A random mechanical shaking mimics the thermal excitation. We exhibit non-Fickian diffusion (single-file diffusion) at large time. We measure the mobility of the particles and compare it to theoretical expectations. We show that our system cannot be accurately descri...
متن کاملDiffusion of Spherical Polystyrene Particles through a
This project involved the study of Brownian motion of polystyrene microspheres in the presence of gravity and a one-dimensional sinusoidal optical potential generated by the interference of two laser beams. An exponential relationship was observed between applied laser power and particle residence time of individual interference fringes. Increasing laser power also revealed a wider distribution...
متن کاملArnold Diffusion of Charged Particles in ABC Magnetic Fields
We prove the existence of diffusing solutions in the motion of a charged particle in the presence of ABCmagnetic fields. The equations of motion are modeled by a 3DOF Hamiltonian system depending on two parameters. For small values of these parameters, we obtain a normally hyperbolic invariantmanifold andwe apply the so-called geometric methods for a priori unstable systems developed by A. Dels...
متن کاملAnisotropic diffusion of spherical particles in closely confining microchannels.
We present here the measurement of the diffusivity of spherical particles closely confined by narrow microchannels. Our experiments yield a two-dimensional map of the position-dependent diffusion coefficients parallel and perpendicular to the channel axis with a resolution down to 129 nm. The diffusivity was measured simultaneously in the channel interior, the bulk reservoirs, as well as the ch...
