Spin spiral state has recently been shown to induce ferroelectricity in single-layer van der Waals (vdW) material NiI2. However, how this state evolves and can be tuned towards the two-dimensional limit remains unclear. Here, we combine spin-polarized scanning tunneling microscopy, layer-by-layer film growth, and multi-scale theoretical modeling to investigate the spin spirals in NiI2 thin films. As the film thickness increases from 1 to 7 monolayers, we observed a continuous increase of spin-spiral wavelength and a rotation of wavevector from near <math><mtext>[110]</mtext></math> to <math><mrow><mtext>[1</mtext><mover><mrow><mtext>1</mtext></mrow><mrow><mo>¯</mo></mrow></mover><mtext>0]</mtext></mrow></math> direction, which evidences a dimensional crossover primarily driven by enhanced interlayer exchange energy. Moreover, we find that the film wrinkles can cause deflection of the spin spiral wavevector, which is caused by local curvature induced modification of exchange interactions. Our findings establish thickness and local strain as two tuning methods for engineering non-collinear helical magnetism and accompanying electric polarization in vdW multiferroics.</div></div>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":"71 18","pages":"Pages 4665-4672"},"PeriodicalIF":20.7,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148838801","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}

Ultraviolet (UV) ML materials, particularly those operating in the solar-blind region (200-280 nm), offer significant advantages for high-signal-to-noise-ratio outdoor sensing owing to minimal interference from sunlight filtered by the Earth's ozone layer. Recent studies have demonstrated that rare-earth ions (Ce3+, Pr3+, Gd3+, Tm3+, Er3+, and Tb3+) and Bi3+ ions facilitate tunable ML emissions across the UVA to UVC spectral range. Advanced material design strategies such as trap-state modulation, piezo-/tribo-electric coupling, and molecular crystal engineering have been used to develop high-performance UV ML materials with enhanced ML intensity and tunable emission wavelengths. Despite these advances, a comprehensive systematic review focusing specifically on UV ML materials is lacking. This review addresses this critical gap by providing an in-depth analysis of the fundamental mechanisms, rational design principles, and performance optimization strategies for UV ML materials. Furthermore, this paper critically summarizes emerging applications in anti-counterfeiting, environmental sensing, structural monitoring, and UV disinfection. By identifying the current challenges and future research directions, this study aims to serve as a foundational reference for accelerating the development and practical implementation of next-generation UV ML materials.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":20.7,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214922","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}

Metastable defects such as stacking faults offer active sites for accelerating sluggish gas redox reactions, but readily undergo electrochemical stress-induced slip and structural collapse during cycling. Inspired by plant traumatic resinosis, we propose a site-specific self-protection strategy that exploits the intrinsic anisotropy of stacking faults to decouple catalytic reaction planes from orthogonal protective functional planes. On the reaction plane, over-coordinated dislocation sites amplify surface electrostatic potential differences and promote Li2CO3 decomposition via nucleophilic/electrophilic interactions. On the functional plane, selective interactions with sulfur-containing electrolyte components induce in situ reconstruction of a multiphase inorganic-organic amorphous interphase, anchoring stacking faults without blocking catalytic sites. As a Li-CO2 proof of concept, stacking-fault-rich molybdenum boride (MoB) delivers 90.13% average energy efficiency over 2500 h and stable operation at 150 °C for nearly 500 h. This work establishes a self-protection paradigm for stable metastable active structures and provides a universal interface design principle for durable Li-gas batteries.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":20.7,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163332","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}
