Photoacoustic monitoring of freezing-induced loading and freeze-casting processes.
Article in Biomedical optics express, 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
Both freezing-induced loading (FIL) and freeze-casting (FC) are used for nano- and microstructured materials fabrication, including core-shell structures, shells, porous materials, as well as ceramics. The crystallization front velocity is a critical parameter for these techniques because it defines the period of lamellar structure during FC and FIL. Here, we show that the photoacoustic method allows us not only to detect the phase transition but also to measure the instantaneous velocity of the crystallization front and track ice crystal position during the crystallization of the sample. Moreover, we demonstrate the possibility of detecting a first-order phase transition in pure water using photoacoustics. Thus, the obtained results give the opportunity for in situ monitoring of the freezing-induced loading as well as the freeze-casting to optimize the parameters of nano- and microstructured materials.
