Mandrel Diameter Is a Dominating Parameter for Fiber Alignment Control in Rotating Mandrel Electrospinning Systems.
Article in Journal of applied polymer science, 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
Aligned nano- and microscale polymer electrospun scaffolds are advantageous for 3D in vitro models of fibrous aligned tissues. A common approach to induce alignment of electrospun polymer fibers is collection on a cylindrical mandrel rotating at high speed. Historically, rotational speed has been considered the major driver in tuning fiber alignment. The comprehensive impact of variable mandrel diameter on fiber alignment in comparison to rotational speed has been minimally investigated. Therefore, this study aimed to investigate the role of mandrel diameter on fiber alignment, fiber volume fraction, and fiber diameter under controlled modulation of common processing parameters. Analysis was performed using scanning electron microscopy (SEM) and the DiameterJ and OrientationJ plugins in ImageJ. Linear regression analysis showed mandrel diameter to be the dominant factor influencing fiber diameter, fiber fraction, and fiber alignment of all samples. These findings suggest that fiber alignment can be more finely and consistently tuned by increasing mandrel diameter rather than increasing rotational speed. This work offers a guide for collecting highly aligned electrospun fibers at low rotational speeds using a rotating mandrel collector for use as tissue engineering scaffolds.
