CHEMISTRY GLOSSARY Brownian motion Braunovo gibanje Brownian motion is the continuous random movement of small particles suspended in a fluid, which arise from collisions with the fluid molecules. First observed by the British botanist R. Brown (1773-1858) when studying pollen particles. The effect ...

The motion of the particles is produced by an alternating magnetic field applied perpendicular to the surface of the container. The mean square displacement of the particles is measured for a range of low concentrations and it is found that following an appropriate scaling of length and time, ...
Scaled Brownian motion with α > 0. The overdamped SBM Langevin equation with time dependent diffusion coefficient D (t) tα−1 and α > 0 is typically used as the definition of SBM54–58, dx (t) = 2D(t) ×ζ (t). dt Here we consider the time dependent ...

Definition of the SubjectThe thermodynamics of small systems describes energy exchange processes between a system and its environment in the low energy range ofa few \( { k_{\mathrm{B}}T } \) whereBrownian fluctuations are dominant [1]. The main goal of this discipline is to identify the ...
The brownian motion is a sort of meeting point of several aspects of abstract mathematics, theoretical physics and real-world applications. We present first an heuristic description of it due to Einstein’s genius, and then we provide a rigorous definition, taking the opportunity to introduce ...
extended to a much broader class of fluid/solid couples. However, such generalization must be performed with caution as there are a number of limitations which can lead to departure from the simple intermittent Brownian motion at the heart of our approach. Depending on the nature of the ...
The limit [Math Processing Error]ω0=0 represents translational (free) Brownian motion. The earlier work (Hakim and Ambegaokar in Phys Rev A 32:423, 1985) concluded that the so defined limit transition is prohibited for spectral densities with [Math Processing Error]s<2. In the present ...
