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

Ostwald ripening of nanoparticles, where larger particles grow at the expense of smaller ones, is typically a thermodynamically driven process that is difficult to control. Here, we report contact-dependent, localized galvanic Ostwald ripening, a mechanism that can harness Ostwald ripening of nanoparticles as a programmable tool for nanofabrication. Using DNA origami to precisely control interparticle distances, we show that silver grows homogeneously on gold seeds until nanoparticle electrical contact triggers asymmetric ripening, driven by size-dependent electrochemical potentials. By programming when and where nanoparticles touch, we direct ripening pathways to create designer heterogeneous nanoparticle structures with enhanced plasmonic properties. In this work, we elucidate the origin of heterogeneous silver growth in nanoparticle clusters and establish design principles for engineering asymmetric nanostructures with predetermined morphologies, advancing both fundamental colloidal nanoscience and plasmonic device fabrication.
