Effect of Sm and Ni co-doping on optical and electrical properties of lead magnesate niobate titanate ceramics.
Article in PloS one, 2026. 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 ability to manipulate the bandgap while maintaining strong ferroelectricity in perovskite oxides offers numerous functional advantages, including multimodal energy harvesting/sensing, current modulation, dual-source actuation, electric-free poling, and enhanced bulk photovoltaic effect. However, bandgap engineering of Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) - renowned for its outstanding piezoelectric properties - via Ni2+ doping remains unexplored, despite its prior success in alkaline niobates. This study provides a comprehensive characterization of the structure-property relationships in Sm/Ni co-doped PMN-PT ceramics, especially for their optoelectrical properties. The results show that Ni2+ doping behaves differently than in alkaline niobates. Nevertheless, Sm/Ni co-doping effectively tunes the phase transition, photoconductivity, charge carrier trapping, and optical absorption while retaining reasonable piezoelectric energy harvesting performance. Overall, this work offers insights into the role of Ni2+ in the band structure of Sm-PMN-PT perovskite and pyrochlore phases.
