Visualizing lattice dynamics, which is typically done using time-resolved X-ray and electron diffraction techniques, yields information about the physical processes involved. However, the detection of atomic motion of an amplitude much less than a picometre has remained challenging. For this purpose, we suggest exploiting the acoustic pulse generated by a spatially localized ultrafast process in the surrounding volume. Its optical detection in a material possessing a narrow polariton resonance provides superior sensitivity. In the validating experiment, we detect the acoustic pulse generated by a 100 attometre thermal expansion of a 100 nanometre metallic film heated with a temperature increase of 0.2 kelvin by a femtosecond optical pulse. Even though the generated acoustic pulse carries dynamical strain with a magnitude of only 10−9, being injected into the polaritonic layer, it can be confidently detected through transient reflectivity.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"28 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979747","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}

Although extensively studied in inorganic materials, their potential in organic-based systems remains largely unexplored. Here we demonstrate highly mobile hot carriers in crystalline two-dimensional conjugated coordination polymer Cu3BHT (BHT, benzenehexathiol) films. Leveraging a suite of ultrafast spectroscopic and imaging techniques, we map the microscopic charge transport landscape in Cu3BHT films following non-equilibrium photoexcitation across temporal, spatial and frequency domains, revealing two distinct high-mobility transport regimes. In the non-equilibrium regime, hot carriers achieve an ultrahigh mobility of ~2,000 cm2 V–1 s–1, traversing grain boundaries up to ~300 nm within a picosecond. In the quasi-equilibrium regime, free carriers exhibit Drude-type, band-like transport with a remarkable mobility of ~400 cm2 V–1 s–1 and an intrinsic diffusion length exceeding 1 μm. These findings position two-dimensional conjugated coordination polymers as versatile platforms for advancing organic-based hot carrier applications.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"121 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940674","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}

Nonetheless, how such structures resist mechanical stimuli that prompt cell–cell rupture is still not fully understood. Here we challenge the conventional views on cell–cell adhesion stability, highlighting the importance of viscous dissipation at the cellular level. Using microdevices to measure the rupture energy of cell–cell junctions and synthetic cadherins to discriminate cadherin binding energy from downstream cytoskeletal regulation, we demonstrate that the balance between cortical tension and cell shape recovery time determines a transition from ductile to brittle fracture in cell–cell contact. These findings suggest that junction toughness, defined as the junction disruption energy, is a more accurate measure of junctional stability, challenging the current emphasis on bond energy and tension. Overall, our results highlight the role and the regulation of energy dissipation through the cytoskeleton during junction deformation for epithelial integrity.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"44 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933406","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}

These interactions occur at subatomic scales and a comprehensive understanding of such phenomena relies on characterization techniques capable of probing the spin and orbital moments at atomic resolution. Although electron energy loss magnetic chiral dichroism has previously enabled the detection of magnetic moments at atomic scales, it was limited to a chromatic-aberration-corrected transmission electron microscope. Although possible, the detection of atomic-scale electron energy loss magnetic chiral dichroism in a scanning transmission electron microscope remains elusive due to challenges associated with convergent beam setups. Here we demonstrate the detection of atomic-scale electron energy loss magnetic chiral dichroism signals in a probe-corrected scanning transmission electron microscope. We not only determine the orbital-to-spin moments ratio for individual atomic planes of an iron crystal but also reveal its local variations at subatomic scales. These findings open the possibility of resolving magnetism down to the orbital level in future studies.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"26 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933407","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}

Given the limited capacity of neurons to regenerate, effective treatments for TBI are lacking. Neural stem cells (NSCs) can differentiate into fully functioning neurons and thus hold promise for TBI treatment. Nonetheless, NSC differentiation and proliferation are slow and inefficient. Studies have shown that piezoelectric stimulation is capable of promoting the differentiation and proliferation of NSCs. Here, we describe barium titanate–reduced graphene oxide (BTO/rGO) hybrid piezoelectric nanostickers that promote NSC proliferation and differentiation. These hybrid nanostickers attach to NSC membranes, serving as long-term generators of piezoelectric potentials upon ultrasound stimulation. BTO/rGO nanostickers promote rapid neuronal differentiation and maturation by activating the voltage-gated calcium channel/Ca2+/calmodulin-dependent protein kinase II/cAMP response element-binding protein pathways. Transplantation of NSCs with BTO/rGO nanostickers into the injured brain region of rats with TBI substantially repairs brain tissue and effectively restores physiological functions after 28 d following 5-min ultrasound irradiation every 2 d. These results demonstrate the potential of the combination of NSCs and BTO/rGO nanostickers for TBI treatment.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"56 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910017","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 double-moiré potentials generated by superposing three atomic crystals create a unique class of tunable quasiperiodic structures that alter the symmetry and spatial distribution of the electronic wavefunctions. By using scanning tunnelling microscopy and scanning tunnelling spectroscopy to study twisted bilayer graphene on hexagonal boron nitride, we unveil a moiré phase diagram defined by the lattice constants of the two moiré lattices (graphene-on-graphene and graphene-on-hexagonal boron nitride), comprising both commensurate periodic and incommensurate quasiperiodic crystals. Remarkably, the 1:1 commensurate crystals, which should theoretically exist at only one point on this phase diagram, are observed over a wide range, demonstrating an unexpected self-alignment mechanism. The incommensurate crystals include quasicrystals, which are quasiperiodic and feature a Bravais-forbidden dodecagonal symmetry, and intercrystals, which are also quasiperiodic but lack forbidden symmetries. This rich variety of tunable double-moiré structures offers a synthetic platform for exploring the unique electronic properties of quasiperiodic crystals, which are rarely found in nature.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"15 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910019","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}
