Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. Everett Rogers, a professor of communication studies, popularized the theory in his book Diffusion of Innovations; the book was first published in 1962, and is now in its fifth edition (2003). Diffusion . Diffusion är ett begrepp som i ljudsammanhang betyder ungefär "spridning".

The process of rapid random movement of the particles of a liquid or gas which eventually form a uniform mixture. 2. [ dĭ-fu´zhun] 1. the state or process of being widely spread. 2. the spontaneous mixing of the molecules or ions of two or more substances resulting from random thermal motion; its rate is proportional to the concentrations of the substances and it increases with the temperature.

diffusion In the process of diffusion of a single solute, a concentration of molecules on one side of a membrane will move through a membrane until there is 2008-10-1 · 1 Chapter 5 Chapter 5: Diffusion Diffusion: the movement of particles in a solid from an area of high concentration to an area of low concentration, resulting in the uniform distribution of the substance Diffusion is process which is NOT due to the action of a force, but a result of the random movements of atoms (statistical problem)1. Diffusivity and 2 Fick’s laws Gas - Gas - Diffusion: Diffusion in dilute gases is in some ways more complex, or at least more subtle, than either viscosity or thermal conductivity. First, a mixture is necessarily involved, inasmuch as a gas diffusing through itself makes no sense physically unless the molecules are in some way distinguishable from one another. Second, diffusion measurements are rather sensitive to the 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 1 The spreading of something more widely. ‘the diffusion of Duchamp’s thought and art’ Diffusion An Artfully-Crafted Photography Annual (Est. 2009) Diffusion is an independent, reader-supported annual that highlights and celebrates artfully crafted photographic artwork including, but not limited to, handcrafted, alternative process, mixed media, installation, photo as object, avant-garde, experimental, etc.

2021-1-8 · The diffusion of innovations theory is a hypothesis outlining how new technological and other advancements spread throughout societies and cultures, from introduction to wider-adoption.

2019-4-10 · Diffusion is the tendency of molecules to spread out in order to occupy an available space. Gasses and molecules in a liquid have a tendency to diffuse from a more concentrated environment to a less concentrated environment.
