On demand controlling of cavitation bubble collapse and jet formation through a free and rigid boundary arrangement.
Article in Ultrasonics sonochemistry, 2025. 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
Cavitation bubbles during their collapse may form fast microscopic jet flows directed either towards a rigid boundary or away from a free surface. Here, we demonstrate experimentally that the jetting direction of a cavitation bubble near the opening of a partially liquid-filled capillary can be controlled by a non-dimensional stand-off distance, which is a function of the bubble position, capillary radius, and liquid filling. The bubble radial dynamics in the experiments are reproduced with a modified Rayleigh equation, and the full flow field is simulated with the compressible Volume-of-Fluid method. Particularly interesting cases are the neutral collapses that show either spherical symmetric flows where the partially liquid-filled capillary becomes hydrodynamically invisible to the cavitation bubble, or a torus bubble upon minimum volume, which demonstrates shock wave amplification and is similar to the one observed near a rigid boundary.
