Dual-Stimuli Chromogenic Membranes for Optical Security: Photochromic and Halochromic Anti-Counterfeiting Applications.
Article in Small (Weinheim an der Bergstrasse, Germany), 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
A dual-stimuli chromogenic platform based on spiropyran-functionalized anodic aluminum oxide (SP-t-AAO) membranes with reversible photochromic and halochromic switching is reported. Surface characterization by electronic images confirms the well-preserved nanoporous morphology, while Energy-dispersive X-ray spectroscopy (EDS) scans reveal uniform grafting to micrometer depths. Grazing incidence X-ray photoelectron spectroscopy (GIXPS) and time-of-flight secondary ion mass Spectrometry (TOF-SIMS) further confirm successful surface chemical modification and pattern fidelity. Orthogonal functionalization is achieved via thiol-yne chemistry and spatially controlled photopatterning using Chinese seasonal-themed photomasks. Upon UV irradiation, the membrane exhibits a pale-to-magenta color change because of spiropyran-merocyanine isomerization; acid exposure further switches the color from magenta to yellow. Both transitions are fully reversible under white light or base treatment. Video analysis reveals rapid halochromic switching kinetics (0.4-4 s), highlighting excellent optical responsiveness. The membrane also demonstrates the chelation toward heavy metal ions such as Cu
