Diffusion - Wikipedia Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration Diffusion is driven by a gradient in Gibbs free energy or chemical potential It is possible to diffuse "uphill" from a region of lower concentration to a region of higher concentration, as in spinodal decomposition
Diffusion - Definition, Examples and Types | Biology Dictionary Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration The material that diffuses could be a solid, liquid or gas

Diffusion and Osmosis - Biology LibreTexts The goal of this tutorial is for you to be able to describe the movement of molecules in the processes of diffusion and osmosis
DIFFUSION Definition Meaning - Merriam-Webster The meaning of DIFFUSION is the state of being spread out or transmitted especially by contact : the action of diffusing How to use diffusion in a sentence
Molecular diffusion - Wikipedia Diffusion from a microscopic and macroscopic point of view Initially, there are solute molecules on the left side of a barrier (purple line) and none on the right The barrier is removed, and the solute diffuses to fill the whole container Top: A single molecule moves around randomly Middle: With more molecules, there is a clear trend where the solute fills the container more and more
Ficks laws of diffusion - Wikipedia In 1855, physiologist Adolf Fick first reported [2] his now well-known laws governing the transport of mass through diffusive means Fick's work was inspired by the earlier experiments of Thomas Graham, which fell short of proposing the fundamental laws for which Fick would become famous Fick's law is analogous to the relationships discovered at the same epoch by other eminent scientists
