Surface Functionality Influences pH- and Solvent-Dependent Colloidal Stability of Cellulose Nanocrystals.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cellulose nanocrystals (CNCs) are promising sustainable nanomaterials for a wide range of applications. Yet, limitations remain in understanding their dispersion behavior in organic solvents and across pH conditions, especially after surface modification. In this work, CNCs were surface-functionalized with carboxy, amino, or vinyl groups and thoroughly characterized. Dispersion behavior was evaluated using dynamic light scattering, including measurements of hydrodynamic diameter and ζ-potential in water solutions at various pH levels and across different solvents. Colloidal stability strongly depends on surface functionality and solvent characteristics. A correlation with Kamlet-Abboud-Taft parameters was identified, linking dispersion behavior to solvent polarity and hydrogen-bonding ability, in relation to the pKa of the surface groups. These findings provide a semiquantitative framework for designing novel materials with CNC dispersions across diverse media.
