In this work, we report a new wax-assisted exfoliation and transfer method that enables the fabrication of MnBi2Te4 heterostructures with both surfaces encapsulated by AlOx. This strategy strongly enhances the transport performances of the topological quantum phases in MnBi2Te4 flakes, which is attributed to the enhancement of magnetism by the AlOx layer. We observe the robust axion insulator state in even-layer device with wide zero Hall plateau and high longitudinal resistivity, and the quantum anomalous Hall effect in odd-layer device with large hysteresis and sharp plateau transition.

However, Chang’e mission samples reveal a lack of KREEP signatures in the sources of mare basalt erupted ∼2.8 and 2.0 billion years ago, raising questions about its contribution to late-stage volcanism. Here, we present geochemical and geochronological analyses of the lunar basaltic meteorite NWA 16286, which crystallized 2201 ± 13 million years ago, representing the youngest known lunar meteorite. Its mantle source shows a high 238U/204Pb ratio (∼2000) and a low εNd(t) value (–4.3), indicating strong KREEP enrichment and extending the duration of KREEP-related magmatism by ∼800 million years. Compiled isotopic data from lunar basalts reveal three volcanic episodes, each characterized by progressively increasing 238U/204Pb and decreasing εNd, suggesting episodic mantle convection. We propose that episodic sluggish mantle overturn or plume-driven upwelling triggered initial decompression melting, followed by increasing incorporation of KREEP components into basalt sources during each episode of younger mare volcanism.</div></div>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":"70 19","pages":"Pages 3265-3271"},"PeriodicalIF":21.1,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This limitation is particularly acute for spatiotemporal vortex beams, where diffraction distorts the beam profile and splits topological charges. While spatiotemporal coupling engineering has enabled diffraction-free (or propagation-invariant) wave packet propagation, achieving stable vortex propagation remains a significant challenge due to inherent constraints of regular wave dispersion. Here, we overcome this challenge by tailoring the wave system's dispersion to achieve both propagation-invariant behavior and stable vortex structures. We present the first experimental demonstration of propagation-invariant spatiotemporal vortex beams that maintain their spatiotemporal profiles and topological charges over extended propagation distances. The ability of these wave packets to stably carry diverse topological charges without splitting or deformation provides critical insights into spatiotemporal vortex dynamics and unlocks new possibilities for applications across optics, acoustics, and beyond.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145318000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We come up with an innovative dual-waste co-recycling strategy that simultaneously achieves high-value reutilization of low-cost spent lithium manganese oxide (LMO) cathodes and efficient depolymerization of diverse polyester wastes. Crucially, the lithium-deficient nature of spent LMO drives partial Mn3+-to-Mn4+ conversion within Mn-O octahedral units, which not only reinforces adsorption and activation of polyester molecules, but also heightens. To be more specific, degraded LMO exhibits 17.5-fold higher activity than pristine counterparts in glycolysis. In comparison with conventional methods, techno-economic analysis confirms the strategy's economic viability, while lifecycle assessment reveals a 98.2 % reduction in greenhouse gas emissions and a 98.5 % decrease in fossil resource consumption. This work establishes a sustainable pathway for upcycling both LIBs and plastic waste, offering a scalable blueprint for advancing circular economy paradigms.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
