Using density functional theory, we demonstrate for the first time that rhombohedral GeTe (r-GeTe) possesses an ultrahigh negative piezoelectric strain coefficient (d33) of -70.87 pC/N, surpassing all previously reported negative piezoelectric materials. This phenomenon arises from the \"quasi-layered\" structure of r-GeTe, comprising alternating strong and weak bonds, which induces a pronounced negative internal-strain contribution and an exceptionally low elastic constant. We further extend our investigation to other IV-VI rhombohedral materials, identifying GeS, GeSe, and SiTe as promising candidates for ultrahigh negative piezoelectricity. In contrast to prior reports, where negative piezoelectricity stems from a negative clamped-ion term that dominates a small positive internal-strain contribution, our findings propose a new material design strategy for large negative piezoelectricity by introducing a significantly negative internal strain, along with the negative clamped-ion term.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":"3630-3636"},"PeriodicalIF":9.6,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143456280","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 outermost dense layer formed during high-temperature thermal chemical vapor deposition (CVD) severely blocks water transport and steam escape. In this work, a technique of femtosecond laser opening hierarchical lamination (FLOHL) enabling hierarchical micro-nano hybrid scissoring of graphene is presented for its structural and performance upgrades. FLOHL not only allows noncontact rapidly hierarchical opening of the blocked layer but also enables opening lamination of close thin-wall graphene into suspended sheets, while maintaining a robust connection with the framework facilitating stable repetitive use for water evaporation. After FLOHL, solar absorption, heat localization, and interfacial wetting are all dramatically enhanced, increasing water evaporation rates from 1.58/1.56 to 1.79/1.77 kg m–2 h–1 for two prototypes under 1 sun irradiation and conversion efficiency from ∼80% to ∼90%, making them better than many solar evaporators built with graphene and its derivatives, including laser-induced graphene.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"22 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143561079","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, depletion of chemically active residues over cross-linking presents a significant challenge to the ability of the resulting bioassemblies to be further engineered and/or maintain specific biological functions. Here, we report a platform approach to cross-link natural proteins via the otherwise chemically inactive residues. This method exploits noncovalent and selective binding of molecularly engineered cucurbit[7]uril macrocycle to aromatic residues that endows the parent protein with additional unique handles for cross-linking. Various proteins are amenable to this approach, yielding bioassemblies with mechanical strength and thermal and enzymatic stability comparable to or exceeding counterparts prepared by some \"gold-standard\" chemical cross-linkers. This macrocycle-assisted platform approach offers a new paradigm for fabricating valuable bioassemblies that overcome the intrinsic limitations of existing methodologies.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":"3489-3496"},"PeriodicalIF":9.6,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447423","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 annealing the sputtered anode-electrolyte assembly with the La0.6Sr0.4Co0.2Fe0.8O3−δ cathode in a single step at 1000 °C, full cells feature heterostructure ceramic multilayers; NiO-GDC nanocomposites with heterointerfaces are in situ constructed, while the multilayer electrolytes are fully dense. The electrochemical performance is significantly enhanced by the insertion of the NiO-GDC nanocomposite anode and the optimization of the film configuration, achieving a peak power density of 2.72 W cm–2 at 800 °C.

In systems with broken inversion symmetry, strong spin–orbit coupling induces relativistic electron interactions such as the Rashba–Edelstein effect (REE). Initially proposed in two-dimensional magnets, applying the REE theory to real three-dimensional systems poses challenges, necessitating experimental validation. In this study, we empirically ascertained an REE-induced intrinsic and extrinsic fundamental unity between two distinct and dissimilar phenomena, namely, charge-to-spin conversion and chiral-spin alignment. Atomically thin quasi-two-dimensional ferromagnetic materials were used to observe such universal unity by examining the thickness dependences of the Heisenberg exchange interaction, the Dzyaloshinskii–Moriya interaction, and spin–orbit torques. The results revealed a correlation that is highly consistent with the underlying theoretical REE model. These findings not only highlight the role of REE in fundamental physics but also illuminate the intricate impact of interfacial effects on magnetic materials.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"2 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546981","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 recently synthesized fluorinated two-layer diamond film (F-diamane) offers an opportunity to enhance photon extraction due to the proximity of color centers to the surface. In this study, we explored three promising defects (BV, SiV, and NV) in F-diamane using density functional theory to assess their potential for single-photon emission. The results show that F-diamane has an ideal electronic structure with a wide band gap, free from inter-band gap states and surface magnetic spins. Additionally, the SiV and NV defects have lower formation energies than those in bulk diamond, suggesting that these defects can be more easily synthesized in F-diamane. Furthermore, the SiV– and NV– centers exhibit optical activity in the visible spectrum with high radiative recombination rates. These findings highlight F-diamane as a promising platform for next-generation quantum emitters and qubits, advancing quantum information processing.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"130 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538580","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}
