The worddiffusioncomes from the Latindiffusionem,diffusio, meaning “a pouring forth”. Diffusion in Physics, Chemistry, and Biology Diffusion in physicsis the movement of particles from an area of higher concentration to an area of lower concentration as driven by thermal energy.(1)This definition...
If there were no differences in concentration, meaning the salt was somehow added to the water evenly, then it would already be spread out in equilibrium, and no diffusion would occur. If the water were too cold, the water molecules would not be moving rapidly, and thus diffusion would ...
The name "passive-mediated transport" gives an important insight into the nature of this process: it is a passive form of transportation, meaning that it uses no energy. In active transportation, chemical energy is expended to move a substance against a concentration gradient. Despite the necessit...

Still, there exists a convenient stochastic representation of this diffusion which provides another layer of physical meaning and facilitates numerical simulations. In the mathematically impressive series of works Antoine Lejay derived such a representation for a system with one barrier56–58 which ...
