Negative diﬀusivity and uphill diﬀusion, that contrast with Fick’s laws, however which can occur in multicomponent and single systems. In this paper, authors present studied results about the dynamics of the uphill diﬀusion in ternary and single system. Results have shown that: i) in ternary systems, the dynamics of negative diﬀusivity is high concentration eﬀect and the combina-tion of coupled diﬀusion eﬀect with high concentration eﬀect is the dynamics of uphill diﬀusion; ii) in single systems, the diﬀerence of temperatures in two areas that is the dynamics of negative diﬀusivity and uphill diﬀusion. Keywords: Dynamics of uphill diﬀusion; dynamics of negative diﬀusivity.
Key words: Dynamics of uphill diffusion; / dynamics of negative diffusivity.
