Reverse diffusion refers to a situation where the transport of particles (atoms or molecules) in a medium occurs towards regions of lower concentration gradients, opposite to that observed during diffusion. This phenomenon occurs during phase separation and is described by the Cahn–Hilliard equation.Reverse diffusion also refers to when water is forced from an region of lower concentration to high.
Famous quotes containing the word reverse:
“During the late war [the American Revolution] I had an infallible rule for deciding what [Great Britain] would do on every occasion. It was, to consider what they ought to do, and to take the reverse of that as what they would assuredly do, and I can say with truth that I was never deceived.”
—Thomas Jefferson (1743–1826)
