... able to generate a tem- perature difference, called the osmotic temperature. This is typically an irre- versible effect because the corresponding entropy production is non-zero as directly seen ... a gradient of concen- tration as evidenced by (3.48) is the Dufour’s effect. It should be observed that the cross-coefficients D T and D F are much smaller than the direct co- efficients like the ... memb...
