1 · What the graph read from it

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.

2 · The registry

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

Switchable control of adhesion is an important feature of many desired applications such as robotic manipulation, medical adhesives, and scalable microassembly. We present the study of the switchable dry adhesion of a shape memory polymer surface comprising nanotips which is based on not only overcoming but also exploiting the adhesion paradox, i.e., controlling surface roughness via the shape memory effect. Here, densely packed sharp nanotips causing an initial high surface roughness are flattened upon heating, pressing and cooling to provide a low surface roughness leading to a strong adhesion. However, the flattened nanotips restore their original shape upon reheating to cause a high surface roughness back resulting in a weak adhesion with the adhesion switchability of more than three orders of magnitude. These switchable adhesion capabilities are demonstrated in a variety of applications ranging from macro-scale robotic pick-and-place and fabric adhesives to deterministic micro-scale device-grade silicon platelet transfer and microLED assembly.
