Influence of the permittivity between fillers and binders on the properties of upside-down composites for recycling purposes.
Article in Materials advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Upside-down composites have recently advanced towards recycling piezoceramics. However, the recycled piezoceramics retain only about 10-30% of the pristine piezoelectric properties. To date, there has been no systematic study on the origin of this limitation and on potential routes for improving these recycled materials. This work addresses this issue by combining empirical and modelling evidence. The phenomenon of the influence of disparate permittivity between the fillers and binders is explained by fitting experimental parameters from sets of lead-based and lead-free upside-down composite samples into the Lichtenecker and Yamada models. Results suggest that for high filler contents, the biasing field permeation caused by the binders that leads to lower piezoelectric properties can be experimentally confirmed and correctly modelled. For lower filler contents, the models significantly deviate from the experimental data due to the distinctive shaping method. This issue indicates the necessity of developing a new theoretical methodology for upside-down composites.
