The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding image overlap in the presented figures. Specifically:

Fig. 1 TEM images appear to contain multiple highly similar areas.

Fig. 8 a4 and b1 appear to contain an overlapping area.

Fig. 9 d4 image appears to contain two highly similar areas.

The authors have stated that the images in Fig. 1 originated from the same source image. They have also provided raw data to address these concerns; however, the same similarities were found in the raw data files by the publisher. The Editor-in-Chief therefore no longer has confidence in the presented data.

None of the authors agree to this retraction.
