Understanding and Controlling the Colloidal Stability of CdSe Nanoplatelets by Solvation Force Engineering.
Article in Journal of the American Chemical Society, 2025. 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
The interaction and steric stability of colloidal nanocrystals are determined by the interplay of various contributions, including van der Waals, dipole-dipole, and solvation forces. Recent simulations have unveiled that the solvation force dictates the colloidal stability of two-dimensional nanomaterials with no experimental validation. Here, we introduce optical-pump THz-probe spectroscopy (OPTP) as a novel approach to track the colloidal aggregation of two-dimensional nanoplatelets. We show that far below the saturation concentration previously determined by scattering methods, OPTP can already report nanoscale aggregations by sensitively probing the short-range free carrier photoconductivity arising from internanoplatelet electronic coupling. Combining the OPTP and molecular dynamics simulations allows us to (1) confirm that increasing the nanoplatelet base facet area results in enhanced solvation force and thus aggregation tendency, and (2) demonstrate that the attraction between the nanoplatelets increases with their chain length for
