Capillarity-induced fold localization in film-substrate systems.
Article in Interface focus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Surface instability and elastocapillarity represent critical phenomena in biological and engineered systems. In this study, we investigate capillarity-induced fold localization in film-substrate systems through experiments and finite element simulations. Upon water droplet deposition, globally ordered wrinkles transform into localized folds. The fold morphology and dimensions depend on the aspect ratio of initial wrinkles. Our results demonstrate that high-aspect-ratio wrinkles facilitate spontaneous formation of closed channels beneath the surface upon fold emergence. Additionally, the morphological transition between wrinkles and folds exhibits reversible control through applied strain adjustment. These findings enable technological applications such as the creation of fold nanochannels and graphene oxide folding. This work establishes a fundamental framework for understanding the interplay between surface instability and elastocapillarity, which represents a crucial mechanism in biological and engineered systems while providing design principles for functional surfaces and devices.
