Study on microwave-assisted synthesis of smart responsive magnetic Janus nanocatalysts for enhanced recovery of extra-heavy oil.
Article in Scientific reports, 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
Extra-heavy oil is an important strategic energy resource, but its ultra-high viscosity severely limits efficient production. Conventional thermal recovery and chemical flooding are often associated with high energy consumption, environmental concerns, and limited reservoir adaptability. In this study, an intelligent responsive magnetic Janus nanocatalyst (IRMJN) was developed and coupled with microwave irradiation to enable low-energy and controllable in situ upgrading and oil mobilization. IRMJN features a spatially separated multifunctional architecture, in which Fe₃O₄ serves as the magnetic core for rapid recovery, MoS₂ nanosheets are selectively anchored on one side as catalytic active sites, and graphene quantum dots enhance microwave absorption to generate a synergistic nanoscale hotspot effect. Long-chain alkyl groups grafted onto the magnetic side further impart interfacial orientation capability. Under optimized conditions, the IRMJN-microwave system reduced the viscosity of extra-heavy oil by more than 95% at a bulk temperature of 100 °C, clearly outperforming microwave treatment alone and conventional catalytic systems. Core flooding tests showed an additional oil recovery of more than 18.5% after water flooding. The catalyst also exhibited excellent magnetic recoverability and cycling stability. These results provide a promising strategy for the green and efficient development of extra-heavy oil resources.
