Herein, we propose a programmable Marangoni motor (PM-motor) to propel centimeter-scale S-aquabots with high maneuverability and adaptability. Lightweight, compact, flexible hybrid electronics are used to precisely release ethanol to achieve controllable propulsion, smart sensing, and wireless communication functions. The PM-motor utilizes the surface tension gradient generated by the ethanol, which is released from leaf-inspired veins and improves fuel efficiency by 3.5 times when compared with traditional Marangoni effect-propelled robots. As a result, the device’s endurance is up to ∼226 s for a navigation distance of ∼5 m with just 1.2 mL ethanol. Benefiting from the leaf-like shape and negligible noise production, the S-aquabots can also blend well with their surroundings. Autonomous response capability is demonstrated by guiding an S-aquabot with laser spots to complete a butterfly-shaped trajectory. Equipped with a mini-camera or digital sensors, untethered S-aquabots deployed on an outdoor pool can capture real-time videos or monitor long-term environmental conditions. This work is beneficial for inspiring insightful design strategies to develop S-aquabots with high practical potential.</div></div>","PeriodicalId":100489,"journal":{"name":"eScience","volume":"5 3","pages":"Article 100335"},"PeriodicalIF":42.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This theoretical study unveils the underlying mechanism of facet-dependent thermodynamic properties in mixed-cation perovskites. The results demonstrate that the (100) facet has higher thermal conductivity than the (110) and (111) facets.

Consequently, we achieve an inverted PSC with an excellent efficiency of 25.12%, accompanied by a significantly reduced temperature coefficient and better long-term stability: a conservation rate exceeding 90% after aging at 85 °C and exposure to persistent light irradiation for 1100 h.
