Reusable Lignin-Derived Free-Standing Carbon Nanofiber Sulfur Hosts
Article in Global challenges (Hoboken, NJ), 2026. 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
As an abundant bio-based resource, lignin can be converted to functional carbon materials, thereby providing a sustainable pathway toward free-standing sulfur cathode design. However, rational carbonization engineering remains essential for optimizing sulfur utilization and polysulfide conversion behavior in lithium-sulfur batteries. In this work, lignin valorization and free-standing electrode design are integrated through electrospinning-assisted fabrication of nanofibers, followed by high temperature carbonization to produce flexible and reusable sulfur hosts. The interconnected fibrous architecture facilitates homogeneous sulfur distribution, while promoting polysulfide confinement and electrochemical stability under high sulfur loading and lean electrolyte. At a sulfur loading of 3.3 mg cm
