The status of Brownian motion in electron microscopy is surveyed. Diffusion effects in solids are manifest, particularly at higher temperatures, while the more rapid processes of surface diffusion can now be observed with unprecedented resolution in scanned probe microscopy. Large, thermally-excited ...
For Brownian motion at sufficiently long times it is sufficient to use the overdamped Langevin equation without the inertia term, to quantitatively describe the particle motion. In other words, the long time limit of the full Langevin equation including the Newton term mẍ(t) coincides with ...

The velocity \( u_x \) is dependent on time, hence, under a periodic motion of the upper plane of Fig. 1, an acoustic wave is generated in the fluid. A time and space dependent velocity field can be associated with the acoustic wave propagating in the medium which can influence rigid...
Owing to their complex morphology and surface, disordered nanoporous media possess a rich diffusion landscape leading to specific transport phenomena. The unique diffusion mechanisms in such solids stem from restricted pore relocation and ill-defined sur
