WebSep 15, 2024 · These molecules diffuse freely in and out of the cell, along their concentration gradient. Though water is a polar molecule, it can also diffuse through the plasma membrane. Figure 9.7.2: Plasma membranes are primarily made up of phospholipids (orange). The hydrophilic ("water-loving") head and two hydrophobic … Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of … See more Diffusion is of fundamental importance in many disciplines of physics, chemistry, and biology. Some example applications of diffusion: • Sintering to produce solid materials (powder metallurgy, … See more Fundamentally, two types of diffusion are distinguished: • Tracer diffusion and Self-diffusion, which is a spontaneous mixing of molecules taking place in the … See more Collective diffusion is the diffusion of a large number of particles, most often within a solvent. Contrary to brownian motion, which is the diffusion of a single particle, interactions between particles may have to be considered, unless … See more • Diffusion – Transport of dissolved species from the highest to the lowest concentration region • Ambipolar diffusion See more Diffusion is part of the transport phenomena. Of mass transport mechanisms, molecular diffusion is known as a slower one. See more Because chemical diffusion is a net transport process, the system in which it takes place is not an equilibrium system (i.e. it is not at rest yet). Many results in classical thermodynamics are not easily applied to non-equilibrium systems. However, there … See more Transport of material in stagnant fluid or across streamlines of a fluid in a laminar flow occurs by molecular diffusion. Two adjacent compartments separated by a partition, containing … See more

WebJul 29, 2024 · Diffusion is different from other transport processes in that it results in mixing without bulk matter flow. How it works is that molecules in motion from thermal energy randomly move about. Over time, this "random walk" leads to uniform distribution of different particles. In reality, atoms and molecules only appear to move randomly. Most of ...
