The Editors have retracted this article [1] because:

• The top left panel of Figure 1a appears to be the same as Figure 1(ii) of [2].

• The bottom right panel of Figure 1a appears to be the same as Figure 1(iv) of [2].

The scanning electron microscopy data reported in this article are therefore unreliable. Mohammed Maniruzzaman, Ali Nokhodchi and Matthew Lam agree with this retraction. Carlos Molina has not responded to any correspondence from the Editors/publisher about this retraction.
