Diffusion . Diffusion är ett begrepp som i ljudsammanhang betyder ungefär "spridning". En diffusor är en reflekterande yta som inte ger en skarp reflex, utan sprider den återvändande ljudenergin i tiden, så att klangen i rummet ökar utan att färgning och andra bieffekter uppstår. 2019-04-10 · Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Passive diffusion is the movement of molecules across a membrane, such as a cell membrane. The movement does not require energy. In facilitated diffusion, a molecule is transported across a membrane with the help of a carrier protein.

Diffusion coefficient is the proportionality factor D in Fick's law (see Diffusion) by which the mass of a substance dM diffusing in time dt through the surface dF normal to the diffusion direction is proportional to the concentration gradient grad c of this substance: dM = −D grad c dF dt. Hence, physically, the diffusion coefficient implies that the mass of the substance diffuses through a
