Improved tribological performance of silica glass
Article in RSC advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 research examined the impact of chemical etching on the friction and wear resistance of glass surfaces. Glass samples were etched using deionized water and ammonium bifluoride solution for 1-60 minutes. The surface morphology, roughness, and wettability were analyzed, and reciprocating sliding tests were performed to evaluate the tribological performance of the etched surfaces compared to bare glass. Finite element analysis was used to examine the stress distribution during indentation. The results showed that chemical etching created micro- and nanoscale surface features that significantly reduced the friction coefficients and improved the wear resistance compared to bare glass, with 10-minute etching showing optimal performance. The enhanced tribological behavior resulted from surface texturing, which dispersed the contact stresses, promoted stable lubricating film formation, and reduced direct asperity contact. This demonstrates the potential of chemical etching as an effective surface modification technique for improving the friction performance of glass in industrial applications.
