The role of viscosity on polymer ink transport in dip-pen nanolithography.
Article in Chemical science, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Understanding how ink transfers to a surface in dip-pen nanolithography (DPN) is crucial for designing new ink materials and developing the processes to pattern them. Herein, we investigate the transport of block copolymer inks with varying viscosities, from an atomic force microscope (AFM) tip to a substrate. The size of the patterned block copolymer features was determined to increase with dwell time and decrease with ink viscosity. A mass transfer model is proposed to describe this behaviour, which is fundamentally different from small molecule transport mechanisms due to entanglement of the polymeric chains. The fundamental understanding developed here provides mechanistic insight into the transport of large polymer molecules, and highlights the importance of ink viscosity in controlling the DPN process. Given the ubiquity of polymeric materials in semiconducting nanofabrication, organic electronics, and bioengineering applications, this study could provide an avenue for DPN to expand its role in these fields.
