Mechanically Robust Photo-responsive Liquid Crystal Elastomers.
Article in ACS omega, 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
Photoresponsive liquid crystal elastomers (LCEs) are promising for applications in soft robotics and smart devices owing to their precise controllability and excellent stability. However, their practical utility is often hampered by limitations such as notably inferior mechanical properties, a single shape memory effect, and inadequate recyclability. To address these challenges, we developed a photoresponsive liquid crystal-polyurethane interpenetrating polymer network (IPN-0.75) that exhibits outstanding mechanical performance, including an ultrahigh tensile stress of 44 MPa and a fracture strain of 1699%. The material also demonstrated excellent recyclability, retaining 93% of its original tensile strength after five recycling cycles. Moreover, IPN-0.75 shows remarkable photostability with a consistent response time (∼8 s) and a maximum bending angle (∼85°) over 10 actuation cycles. By integration of a triple shape memory effect and overcoming the mechanical weaknesses of conventional LCEs, this work opens up new possibilities for advanced applications in adaptive and sustainable soft actuators.
