This scalable nanomanufacturing technique harnesses high-temperature/pressure plasmas to drive phase transitions, converting PBA nanocubes into N-doped carbon nanosheets embedded with ultrafine magnetic nanoalloys. Unlike conventional exfoliation method, LSPT2D enables chemical phase engineering, preserving structural integrity while imparting exceptional properties. Prussene exhibits a high saturation magnetization (108.3 emu/g) and enhanced conductivity due to its conductive carbon matrix. Demonstrating transformative electromagnetic wave absorption, it achieves a reflection loss of −51.7 dB and a 5.87 GHz effective bandwidth across GHz–THz frequencies, surpassing state-of-the-art absorbers. These attributes position Prussene as a breakthrough for stealth technologies and ultrahigh-frequency communications. This work establishes a scalable paradigm for synthesizing chemically modified 2D materials, unlocking applications in catalysis, energy storage, and multifunctional nanoelectronics. Prussene’s innovation lies in its synthesis-process-property triad, heralding a new era in high-performance nanomaterials.","PeriodicalId":388,"journal":{"name":"Matter","volume":"23 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their instability in moisture hinders practical use, highlighting the need for an atomic-scale understanding of their degradation mechanism. Here, we uncover water-induced degradation pathways of perovskite nanocrystals using in situ liquid-phase transmission electron microscopy, revealing a distinctive dissolution process driven by ion solvation. The dissolution rates vary according to crystallographic direction, influenced by the surface polarity of different crystal facets, leading to a shape transformation from nanocubes to nanospheres. These observations are further supported by in situ X-ray scattering analysis. Notably, surface passivation of perovskite nanocrystals with halide ion pair ligands provides effective edge passivation, alters the degradation trajectories by preserving their cubic shape during the initial stages, and significantly reduces the overall degradation rate. This study offers critical insights into the water-induced degradation mechanisms of perovskite nanocrystals, potentially guiding strategies to enhance their stability.","PeriodicalId":388,"journal":{"name":"Matter","volume":"60 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of I atom inhibits the O–O bond breakage for enhancing the selectivity of 2e– ORR from 56.5% to 87.0%, thus promoting the continuous natural sunlight-driven photosynthesis of H2O2 directly from water and air, showing a high SCC efficiency of 1.88% and the operational stability of over 200 h.

However, the spectrally engineered RCC’s thermal regulation behavior relies heavily on clear weather, limiting the development of its adaptive thermal management performance and high cooling power. Inspired by the skin’s thermo-regulation, we report a bionic skin meta-gel coating (BSMC) with an adaptive spectrum and moisture modulation capability through hierarchical structure design and localized molecular confinement engineering. Autonomous thermal regulation and high cooling power are attained for the BSMC. Compared to conventional RCC, the BSMC achieves superior cooling performance (a reduction of 4°C) at high temperatures. Conversely, the BSMC can heat a space via photo-thermal effect at low temperatures. Moreover, the BSMC addresses heat accumulation in thermal camouflage nets. According to calculations, the BSMC improves cooling power by 233 W/m2 and significantly decreases global CO2 emissions by 1.9 billion tons/year. The BSMC solves the bottleneck of RCCs and promotes global low-carbon development.","PeriodicalId":388,"journal":{"name":"Matter","volume":"8 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143678119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the synthesis of aggregation-induced electrochemiluminescence (AI-ECL) luminophores with high quantum efficiency requires complicated procedures, a supramolecular strategy is proposed for constructing multicomponent nanoaggregates with co-emissive ECL. Aggregation-induced emission (AIE) active tetraphenylethylene (TPE) was used as a molecular matrix to disperse the aggregation-caused quenching (ACQ) luminophores with high quantum efficiency, boron dipyrromethene (BDP), and rhodamine B (RhB). Co-emissions of both molecular matrix and doped luminophores were achieved. The synergistic effects of the supramolecular interactions for enhancement of emission efficiency were confirmed by spectral measurement and molecular dynamic simulation. Small nanoaggregates with higher ECL efficiency were prepared on microfluidic chips and were used as nanolabels for sensitive ECL immunoassays.","PeriodicalId":388,"journal":{"name":"Matter","volume":"126 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
