At each time step, update concentrations based on reactions of molecules within a voxel, and diffusion between neighboring voxels based on concentration differences (i.e., the diffusion …

Diffusion equation: How does the concentration change at a given location and in time given that there are fluxes in the system? This is a partial differential equation which in practice is hard to …

Due to random motion, molecules of a high concentration will tend to flow towards a region in space where the concentration is lower. Examples: A dye injected into solution spreading …

Diffusion processes are important in many applications in science and engineering. Diffusion occurs when a system is not in equilibrium and random molecular motion tends to bring …

Diffusion describes the spread of particles (which can also be atoms, molecules) through random motion usually (but not always) from regions of higher concentration to regions of lower …

Common: Difusion is the process by which particles move naturally from regions of high concentration to regions of low concentrations. What is natural? How do they “know” where to …

The processes of diffusion, osmosis, and filtration are responsible for the movement of materials into and out of body cells as well as the exchange of molecules between body fluid …
