Self-Assembled Hollow Gyroids with Bicontinuous Mesostructures: A Highly Robust Electrocatalyst Fixation Platform.
Article in Advanced materials (Deerfield Beach, Fla.), 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 electrochemical degradation of Pt/C in commercial proton exchange membrane fuel cells (PEMFCs) is a major challenge that limits their durability and performance. This degradation mainly arises from carbon corrosion, which facilitates the detachment of electrocatalyst particles that are weakly bound to catalyst supports. Herein, unusually robust hollow gyroid morphologies designed for strong electrocatalyst fixation and extensive surface accessibility during oxygen reduction reactions (ORR) are reported. To obtain self-assembled gyroid nanostructures using a poly(styrene-b-2-vinylpyridine) (PS-b-P2VP) block copolymer, a solvent vapour treatment with dimethylformamide, which is highly selective for the P2VP block, is applied. It is discovered that retaining residual solvent in the gyroid-forming P2VP microdomain before carbonization is crucial for forming hollow gyroids with embedded electrocatalysts. These hollow gyroid carbon-Pt (HGC-Pt) nanostructures exhibit a 3.6-fold enhancement in electrochemically active surface area compared to solid gyroid carbon (SGC) counterparts. Based on systematic analyses, this exceptional electrochemical stability is attributed to greatly enhanced surface accessibility derived from the hollow geometry, uniform and robust catalyst embedding, and extensive pyridinic nitrogen doping from the P2VP block.
