Hydroxyl chemistry regulation of cellulose biopolymers for aqueous zinc battery binders.
Article in Nature communications, 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
Aqueous batteries offer inherent safety and low cost, but the inherently fixed physicochemical functionality and poor interfacial compatibility of existing binders limit their ability to boost positive electrode performance. Here we present a hydroxyl-chemistry regulation strategy that transforms cellulose, an abundant biopolymer on Earth, into a high-affinity, interfacially compatible binder that stabilizes high-capacity, shuttling-prone positive electrodes. By selectively opening the rigid cellulose ring structure within its molecular chains, we enhance dipole polarity, chain flexibility, and intermolecular hydrogen-bond density, thereby increasing functional-group accessibility and interfacial adhesion. These molecular-level modifications drive the formation of a dense nanofibrous network that conformally encapsulates active particles and anchors polyiodides, accelerating redox kinetics and reinforcing electrode stability. Iodine positive electrode incorporating the engineered binder deliver a reversible capacity of 150.9 mAh g
