Two corrections in the above manuscript should be noted:
The estimated velocity value O(10−3 m s−1) reported in line 2 of page 390 was not measured directly. A discussion about a revised theoretical estimate of the velocity is provided in the Supporting Information. The value of the electrical conductivity reported in the Section 2.1 is not accurate, as established using a new and more precise measurement setup. The detailed repercussions of these corrections are clearly discussed in the Supporting Information.
