Author instructions
A Graphical Abstract should allow readers to quickly gain an understanding of the main take-home message of the paper and is intended to encourage browsing, promote interdisciplinary scholarship, and help readers identify more quickly which papers are most relevant to their research interests.
Authors must provide an image that clearly represents the work described in the paper. A key figure from the original paper, summarising the content can also be submitted as a graphical abstract.
Graphical Abstracts should be submitted as a separate file in EES by selecting “Graphical Abstracts" from the drop-down list when uploading files.

Specifications:
A Graphical Abstract should be a one-image file and should visualize one process or make one point clear. For ease of browsing, the Graphical Abstract should have a clear start and end, preferably "reading" from top to bottom or left to right. Try to reduce distracting and cluttering elements as much as possible.
