Developing general methods to design altermagnets, particularly in a low dimension, is highly desirable. Here, we propose that breaking the spatial inversion symmetry of crystals can produce altermagnetism in antiferromagnetic monolayers. By applying Janus structurization to two-dimensional (2D) FeSe-type monolayers, 41 polar altermagnets were successfully identified through first-principles calculations, confirming the feasibility of our proposed approach. Furthermore, via systematic screening, we obtained 29 altermagnets with significant spin splitting (>0.5 eV) and high Néel temperatures (above liquid nitrogen temperature). Moreover, using 2D Mn2PSe as an example, we revealed the mechanism of how polarity drives the transformation of antiferromagnets into altermagnets and demonstrated its anisotropic spin current generation and notable spin Hall effect. This work paves a way for realizing high-performance and multifunctional nanoaltermagnets.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"35 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144146118","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}

To address this, we designed an artificial solid–electrolyte interphase (SEI) by grafting a fast Na+ ion conductor, Na5GdSi4O12, with oxygen vacancies (NGSO-Vo), onto a glass fiber (GF) separator. This unique structure combines fast Na+ conduction (8.55 mS cm–1) with anion immobilization, achieving a high Na+ transference number (0.9) in a conventional NaClO4/PC electrolyte. The NGSO-Vo-modified GF exhibits exceptional mechanical stability, effectively suppressing dendrite growth. As a result, Na||Na symmetric cells achieve an ultrahigh current density (30 mA cm–2) and long-term cycling (1500 h at 20 mA cm–2). Moreover, Na3V2(PO4)2F3||Na pouch cells with high mass loading (24 mg cm–2) demonstrate a record stability (4000 h).

After topical application, this nanomedicine bearing vascular endothelial growth factor (VEGF) and tumor necrosis factor alpha (TNF-α) aptamers crosses the stratum corneum and enters the deep layers of psoriatic site, from which it specifically inhibits VEGF-mediated keratinocyte proliferation and TNF-α-mediated inflammatory responses simultaneously. More importantly, the circular aptamers further promote the nuclease resistance, targeted recognition, and transdermal effect of the nanomedicine, as compared to their linear counterparts. These improved synergistic actions effectively prevent and cure psoriasis of mice induced by imiquimod.

While extensive correlations exist between structure and spectroscopy in molecular isocyanide–metal systems, interactions of isocyanide with crystalline metallic surfaces, where ligands often bind in various geometries, remain underexplored. Conventional vibrational spectroscopies such as infrared and Raman spectroscopies lack the molecular-scale resolution to distinguish this binding inhomogeneity. In contrast, inelastic electron tunneling spectroscopy with scanning tunneling microscopy (STM-IETS) directly visualizes ligand adsorption geometries and their vibrational signatures. Using STM-IETS, we investigate a metal-adsorbed m-terphenyl isocyanide ligand and find that the adsorption geometry on Cu(100) induces a significant shift in isocyanide stretching frequency, more prominent than replacing Cu(100) with Ag(111). Density functional theory confirms that this shift arises from atomic-scale variations in coordination environments. This study elucidates how precise binding influences the vibrational fingerprints of isocyanide ligands, an often-overlooked factor in understanding the isocyanide–metal interplay.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"45 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137197","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, achieving multimode tunability remains challenging and requires further efforts. This paper presents an on-site tunable twisted bilayer photonic crystal (TBPhC) composed of two ultrathin silicon nitride photonic crystal films stacked into moiré patterns, each only 50 nm thick. These ultrathin photonic crystals support guided-mode resonances and form an optical resonator through interlayer coupling, simultaneously generating twist-tunable moiré chiral resonances. Notably, compared to hundred-nanometer scale counterparts, this deep-subwavelength photonic crystal thickness enhances near-field coupling, enabling the tuning of multiple resonant modes at micron-level spacing, thus allowing for more flexible manipulation. Experimental results demonstrate that this ultrathin resonant configuration enables active control of resonant chiroptical responses by adjusting the interlayer distance and twist angle, thereby modulating the polarization state of light at the telecom region and opening new possibilities for dynamic polarization control in advanced optical devices.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"26 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137042","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}

By employing aberration-corrected transmission electron microscopy, we directly visualize the atomic structures of GBs in halide perovskites, uncovering the emergence of flexoelectricity and associated polarization-induced shift-currents. We demonstrate that a large strain gradient at 52° GBs induces significant flexoelectric polarization. This flexoelectricity is observed across GBs with different compositions and misorientation angles. First-principles calculations confirm that such flexoelectric polarization can enhance the photovoltaic effect, resulting in a shift-current of ∼15 μA V-2.
