Nd-doped CuO/ZnO and ZnO/CuO heterojunctions for simultaneous UV blocking and malachite green detoxification.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
A novel two-step wet-chemical synthesis produced neodymium-doped core/shell heterojunctions, Copper(II) oxide (neodymium)/Zinc oxide(CuO(Nd)/ZnO and Zinc oxide (neodymium)/Copper(II) oxide ZnO(Nd)/CuO), with tunable optoelectronic and photocatalytic properties. Structural characterization via x-ray diffraction (XRD) and transmission electron microscopy (TEM) reveals uniform crystallite sizes (6.3-31.4 nanometers- nm) and distinct morphologies: hexagonal for CuO(Nd)/ZnO and spherical for ZnO(Nd)/CuO. Incorporating neodymium induced lattice strain (7.8-10.2 × 10⁻⁴) and increased Urbach energies (5.0-15.3 millielectron volts-meV), enhancing defect states. Tauc analysis demonstrated bandgap narrowing to 2.49-3.17 eV for ZnO and 1.49-1.55 eV for CuO. ZnO(Nd)/CuO achieved a remarkable 94.6% degradation of malachite green (MG) under cost-effective 500 W (W) white light irradiation. This significantly surpasses the performance of undoped systems (by 5%) and generally exceeds that reported for other nanocomposites (≤ 90%) in the literature. Conversely, CuO(Nd)/ZnO exhibited 89.04% ultraviolet blocking efficiency at 280-315 nm (UV-B), outperforming polymethyl methacrylate (PMMA) with ZnO quantum dots (50-60%) and ZnO nanoparticles with polylactic acid composite films (15-75%). These enhancements stem from neodymium(III) (Nd³)-mediated trap states, optimized band alignment, and charge separation at the heterojunction interface. Integrating rare-earth doping with core/shell architecture provides a scalable route for high-performance photocatalytic and ultraviolet-protective materials.
