Imaging molecular structures and interactions by enhanced confinement effect in electron microscopy.
Article in Nature communications, 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
Atomic imaging of molecules and intermolecular interactions are of great significance for a deeper understanding of the basic physics and chemistry in various applications, but it is still challenging in electron microscopy due to their thermal mobility and beam sensitivity. Confinement effect and low-dose imaging method may efficiently help us achieve stable high-resolution resolving of molecules and their interactions. Here, we propose a general strategy to image the confined molecules and evaluate the strengths of host-guest interactions in three material systems by low-dose electron microscopy. Then, we change the guest molecules to analyze how each kind of interaction strength influences the imaging quality of these molecules by using a same parameter, the aspect ratios of imaged molecular projections. In the material systems of perovskites (ionic) and zeolites with adsorbed molecules (van der Waals), we can obtain a clear image of molecular configurations by enhancing host-guest interactions. Even in metal organic framework (coordination) system, the atomic structures and bonds of aromatics can be achieved. These results provide a general description on the relation between molecular images and interactions, making it possible to study more molecular behaviors in wide applications by real-space imaging.
