A robotic approach to polymerisation kinetics: a case study on copolymerisation parameter estimation.
Article in Chemical science, 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
Automation and high-throughput (HTP) experimentation are transforming chemistry, yet the high cost of robotic platforms limits accessibility. Pipetting robots such as the Opentrons OT-2 provide a cost-effective, open-source alternative, but their application to radical polymerisation in high throughput formats has been restricted by challenges such as deoxygenation at microlitre scale. Here, we establish a robust workflow for thermal radical polymerisation in a 48-well reactor using the OT-2, supported by custom 3D-printed components for automated NMR sample preparation. This system enables rapid and reproducible data generation while eliminating human bias from experimentation. We demonstrate its utility through the study of copolymerisation kinetics, where inconsistent methods, reporting, and model selection have created significant data gaps for predictive modelling. By combining robotic HTP experimentation with IUPAC-recommended evaluation methodology, we provide standardised datasets for predicting reactivity ratios of six monomer pairs: BMA-BA (
