Correction for ‘The effect of wall depletion and hydrodynamic interactions on stress-gradient-induced polymer migration’ by Hossein Rezvantalab et al., Soft Matter, 2016, 12, 5883–5897.


We noticed, after publication of the paper, that the product of the first-order concentration and first-order migration flux was inadvertently left out of the second-order convection–diffusion equation used in calculating the second-order contribution to the concentration field, c(2); the correct expression is
 
Dc(2),i,i + vic(1),i + (c(0)[J with combining tilde]m(2)i),i + (c(2)[J with combining tilde]m(0)i),i + (c(1)[J with combining tilde]m(1)i),i = 0 (3.14)
with the last term on the left-hand side giving the additional second order contribution. Note that this is simply a typo in writing the expression in the main text, while all the analysis and the results reported for second-order expansion are based on the correct perturbation including the c(1)[J with combining tilde]m(1)i term.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
