Question

Is the diffusion coefficient time-dependent?

Answer 1

In general, the standard diffusion coefficient defined by Fick's law, and the corresponding diffusion equation cannot describe the nonlinear time dependence of the MSD, and there is no simple comparable propagator for anomalous diffusion, although many sophisticated approaches have been introduced to model anomalous ..

Answer 2

Heya....

See the answer =====

Ques,, Is diffusion coefficient time dependent ??

Ans --

• The coefficient diffusion is defined by the Fick's law and the corresponding diffusion equation describe non linear time dependency of MSD...

• There is no simple comparable prolongate for anomalous diffusion ...

So yes...It is somewhat time dependable...

Thank you
