A PDMS review figure as a hierarchy example

Read the hierarchy before copying the outline

The PDMS gas-separation-membrane archive provides a visual example of categories arranged around a common topic. A membrane layer, a modification strategy and an application answer different questions. Keep these levels separate rather than presenting them as interchangeable wedges.

What the case does not establish

This note analyzes layout, not membrane performance. It does not add experimental values or claim that SCI Artisan's editor produced the original artwork. Preserve the scientific paper, project attribution and image-use conditions in the original project archive.

Apply the structural check through the online review-figure workflow, or scope a commissioned illustration.
