Bending and vibration behavior of functionally graded piezoelectric nanobeams considering dynamic flexoelectric and surface effects.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This paper develops a more comprehensive theoretical model for functionally graded material (FGM) piezoelectric nanobeams. The model incorporates a Winkler-Pasternak linear elastic foundation and fully accounts for the effects of dynamic flexoelectric, surface effects, and higher-order electric fields. The purpose of this study is to investigate the bending behavior and free vibration characteristics of Euler-Bernoulli beam models considering functionally graded materials. The governing equations and boundary conditions are produced using Hamilton's variational principle. The Fourier series expansion approach is used to create the analytical solution for the bending problem. Then the analytical equation for the natural frequencies is obtained using the Navier method. The bending performance, electromechanical coupling characteristics, and normalized natural frequencies of FGM piezoelectric nanobeams are all significantly impacted by higher-order electric fields, gradient index, dynamic flexoelectric effects, surface effects, and the Winkler-Pasternak elastic foundation, according to numerical analysis. For the design and optimization of micro/nano energy harvesters and resonators, this paper offers theoretical insights and references.
