After publication of the original article , it came to the publishers’ attention that the author’s corrections provided at the proofing stage had been misinterpreted.
Firstly, Mingliang Xu should not have appeared in the author list. It was agreed between the authors that Dr Xu should have been removed from the authorship prior to publication, but the change requested at proofing was misconstrued as transferring the corresponding author role to Yongjie Liu. The post-publication removal of Dr Xu has been approved and the correct authorship of the article is published in this erratum. The original article has also been corrected.
In addition, updated versions Figs. 3, 5 and 6 were provided by the author during proofing, but this correction was overlooked. The correct versions of these Figures are now present in the original article, and also published in this erratum.
