Graphene offers an ideal building block, but multiscale defects such as disordered stacking and voids prevent macroscopic assemblies from realizing its intrinsic properties. Here we show that ultrahigh-ratio draw spinning, enabled by the polymer-like viscoelasticity of two-dimensional sheets in viscous solvents, produces graphene fibres with a tensile strength of 5.9 GPa, a Young modulus of 963 GPa, a thermal conductivity of up to 1,720 W m−1 K−1 and an electrical conductivity of 1.3 MS m−1. A high-ratio draw spinning up to 11, combined with high-temperature annealing, efficiently removes defects and produces densely packed, highly ordered graphene fibres. These properties surpass most existing strong and thermally conductive fibres. This work provides a versatile route for assembling two-dimensional materials into high-performance macroscopic structures and expands opportunities for multifunctional materials. Polymer-like viscoelasticity of two-dimensional graphene oxide in viscous solvents enables ultrahigh-ratio drawing during fibre spinning, which achieves macroscopic graphene fibres with a compelling combination of high mechanical strength, thermal conductivity and electrical conductivity.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"25 10","pages":"1732-1740"},"PeriodicalIF":38.0,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148851156","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, the issues of void formation and dendrite growth both remain unsolved. Here we demonstrate that void formation is controlled by the product of lithium full stripping areal capacity and applied current density, which we define as the void suppression capability (VSC). The VSC is enhanced by increasing self-diffusivity and initial lithium atom concentration. Using a Mg-1 wt% La inoculant in molten lithium (LiMgLa) to refine grains, lithium self-diffusivity and VSC are enhanced, resulting in an increase in the critical current density/capacity from 1.2 mA cm-2/0.6 mAh cm-2 for the LiMg anode to 2.2 mA cm-2/1.1 mAh cm-2 for the LiMgLa anode. The LiMgLa anodes enable stable lithium plating/stripping for over 1,200 h at 0.7 mA cm-2 at room temperature. Phase-field modelling shows that the interfacial overpotential will be higher than the critical overpotential of the electrolyte when the stripped capacity is larger than 70% of the full depletion capacity, leading to dendrite growth and cell failure. Our observations offer a route to the design of all-solid-state lithium metal batteries with high powers and energy densities.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148830886","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, how they crystallize remains poorly understood because early nuclei are small, transient and chemically complex. Here we advance atomic electron tomography to determine the three-dimensional atomic structures and local chemical order of 8,160 high- and medium-entropy alloy nuclei. We find that nucleation proceeds through gradient ordering, in which structural order is highest at the core, decreases smoothly towards the boundary and is coupled to local chemical order. Most nuclei coalesce with nearly aligned crystal lattices, whereas a minority form twin boundaries. We develop the gradient nucleation pathways model, which generalizes classical nucleation theory by incorporating spatially varying structural order within each nucleus. The model captures diffuse, partially ordered nuclei, recovers classical nucleation theory in the sharp-interface limit and reveals multiple intermediate states. These results provide an atomistic framework for understanding crystal nucleation and growth across a broad range of materials.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148818921","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}

Here we demonstrate the robust electrical reading and deterministic switching of perpendicular altermagnetic order by designing a Dirac semimetal/altermagnet heterostructure of PtTe2/CrSb. This engineered interface enables anomalous Hall read-out via the altermagnetic proximity effect and delivers efficient spin-orbit torque for manipulating the epitaxial perpendicular Néel vector in CrSb. These findings substantially broaden the functional scope of altermagnetic heterostructures and pave the way for scalable altermagnetic memory.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148813631","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}

Here we show that the chelating ligand 1,10-phenanthroline acts as an organic flux that lowers the glass transition temperature of selected MOFs and induces ligand exchange during melting, thereby enabling control over local coordination and global topology in MOF glasses. In Co2+-based systems, phenanthroline coordinates to the metal nodes, increases the coordination number and reduces network connectivity by forming terminal ligands. This coordination sphere engineering affords a level of structural control not readily achievable in conventional inorganic or organic glasses. Crucially, the lower processing temperature suppresses thermal decomposition, enabling the synthesis of Co2+-based MOF glasses free of magnetic impurities. These glasses exhibit antiferromagnetic coupling and represent unique examples of magnetic MOF glasses formed by melt quenching. Finally, we extend the strategy to otherwise non-meltable carboxylate-based MOFs, establishing flux-mediated ligand exchange as a versatile route to hybrid glasses with tailored connectivity and properties.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148813657","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}

In this Review, we present the current understanding of the ultrafast response of spins in antiferromagnets to ultrashort laser stimuli. We progressively transition from equilibrium to ultrafast out-of-equilibrium dynamics, highlighting fundamental pillars that make the ultrafast magnetic response in antiferromagnets qualitatively distinct, compared with that in ferromagnets. Throughout this Review, we demonstrate how ultrashort laser excitation serves as a powerful tool for investigating and controlling antiferromagnets, providing access to coherent terahertz spin dynamics, dissipation mechanisms, nonlinear interactions and magnetic switching on ultrafast timescales. This unique combination of rich fundamental physics and advanced control capabilities positions antiferromagnets as both a fascinating subject of basic research and a promising platform for next-generation ultrafast and low-dissipation spintronic technologies. This Review presents a symmetry-based classification of antiferromagnetism and discusses the progress and challenges in detecting, exciting and probing the dynamics of antiferromagnets.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"25 9","pages":"1519-1532"},"PeriodicalIF":38.0,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148795932","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}
