Random motion, also known as Brownian motion, is the chaotic, haphazard movement of atoms and molecules.Random motion is a quality of liquid and especially gas molecules as described by the kinetic theory. The botanist Robert Brown first noticed this phenomenon in 1827, and Albert Einstein later ...

In this chapter we present an overview of random walk models for random particle movement. In a biological context, the notion particle refers to any identifiable unit as molecules, biological cells, or organisms. The motion of particles in space can be directed or random , independent or ...
We supposed the main cause for decrease of the reaction rate constant to be decrease of the intracrystalline diffusivity by deposition of organic species. Thus the simulations of a two dimensional lattice model with random movement of molecules were carried out in various proportion of the plug in...
We begin with a description of biological membranes, structures that regulate the movement of material into, out of, and within the functional compartments of a cell. At the core of a membrane is a layer of water-repelling molecules. This layer has the effect of restricting the free ...
We now know that Brownian motion arises from random collisions in which moving liquid molecules give many small pushes to a suspended particle. In 1905 Albert Einstein published this explanation, as well as the first convincing mathematical demonstration of it. Several years later the American ...
According to Devreotes, a key component of a cell's machinery is a crisscrossing network of protein chains that wrap around the inside edge of the cell, giving it shape and structure and inspiring the name "cytoskeleton." To allow movement, this network must build itself up in a given ar...
"Since ellipsoids are longer than they are wide, they experience more water resistance going in one direction than the other," said Yilong Han, a post-doc in Yodh's research group. "These effects are larger in two-dimensions than in three, and the coupling of the rotational movement –- ...
