Tribological behaviors of stator rubber with hexagonal micro-texture and enclosed groove of bionic honeycomb structure.
Article in iScience, 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
The model of hydrodynamic lubrication in the flow field was developed by coupling of hexagonal micro-texture and enclosed groove with a bionic honeycomb structure. The lubrication performance and friction characteristics of the friction pair between the stator and rotor of a screw pump were evaluated on the simulated and experimental results of high acrylonitrile rubber. As the groove depth increased, the cavitation effect and increasing vortex energy losses weakened the friction reduction and wear resistance. An additional bucket-shaped vortex flow was formed beneath the original vortex in the double wedge-shaped overlapping groove, while a new dustpan-shaped divergent flow was formed in the single wedge-shaped boundary groove. Tiny erosion pits were present at the outer edges of the groove bottom after immersion. Slight wear marks were observed on the rubber surface, with fatigue peeling in the texture chamfers, thereby deepening wear marks in some parts of the extended texture region.
