Thioether-Linked Single-Molecule Junctions with Coinage Metal Contacts.
Article in Nano letters, 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
The influence of changing electrode material on the electrical and mechanical properties of metal-molecule-metal junctions is relatively poorly understood, yet an improved understanding of these interfaces remains critical to the implementation of such systems as active elements in real-world circuits. Accordingly, here we study single-molecule junctions comprising thioether-linked alkane and oligophenyl wires formed under an inert atmosphere using gold, silver, and copper electrodes. Break junction experiments and computational simulations reveal that the conductance of junctions with different contacts typically decreases in the order gold > silver ≥ copper. Such trends cannot be explained solely from the differences in work function for these metals, which are modulated in junctions by the interface dipole. Transport calculations also expose the influence of electronic coupling to the electrodes, which is strongest for gold. Together, this study charts a coherent path toward a more complete understanding of the role of the electrode in single-molecule devices.
