Studying spin-mediated thermal transport is crucial for spin caloritronics, enabling efficient heat dissipation in microelectronics and advanced thermoelectric applications. However, designing quantum materials with controllable spin transport is challenging. Here, highly textured spin-chain compound Ca2CuO3 is synthesized using a solvent-cast cold pressing technique, aligning 2D nanostructures with spin chains perpendicular to the pressing direction. The sample exhibits high thermal conductivity anisotropy and an excellent room-temperature thermal conductivity of 12 ± 0.7 W m−1 K−1, surpassing all polycrystalline quantum magnets. Such a high value is attributed to the significant spin-mediated thermal conductivity of 10 ± 1 W m−1 K−1, the highest reported among all polycrystalline quantum materials. Analysis through a 1D kinetic model suggests that near room-temperature, spinon thermal transport is dominated by coupling with high-frequency phonons, while extrinsic spinon-defect scattering is negligible. Additionally, this method is used to prepare textured La2CuO4, exhibiting highly anisotropic magnon thermal transport and demonstrating its broad applicability. A distinct role of defect scattering in spin-mediated thermal transport is observed in two spin systems. These findings open new avenues for designing quantum materials with controlled spin transport for thermal management and energy conversion.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"157 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673674","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 study commences by outlining the shared mechanism by which F and I enhance solid-state lithium metal batteries' electrochemical performance. In particular, F and I can considerably improve ion transport capacity through chemical means such as intermolecular interactions and halogenation reactions. Furthermore, the utilization of F and I significantly enhances the stability of the electrolyte/electrode interface via physical strategies, encompassing doping techniques, the application of surface coatings, and the fabrication of synthetic intermediate layers. Subsequently, the characteristics of F and I used in Li-based batteries are elaborated in detail, focusing on the fact that F can provide additional energy density as an anode material but by different mechanisms. Additionally, I can considerably activate dead lithium at the negative electrode, and F can act as a new carrier. Finally, a rational concept of the synergistic effect of F and I is proposed and the feasibility of F–I bihalide solid electrolytes is explored.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"57 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673710","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 catalytic efficiency, however, is significantly constrained by the insufficient piezoresponse of sonosensitizers at low-intensity ultrasound (LIU) accompanied poor separation efficiency of charges, resulting in unsatisfactory sterilization. To address the dilemma, a piezocatalytic bio-heterojunction (P-bioHJ) consisting of BiOI and few-layered Mxene is constructed for rapid antibacterial. The engineered P-bioHJ not merely possesses a relatively narrow-bandgap for responding to the sonoluminescence emitted by the sonocavitation effect, but rather induces the interfacial polarization and the generation of oxygen vacancies to facilitate the effective separation of carriers, leading to a burst of radicals for rapid sterilization. Transcriptomic analysis reveals that P-bioHJ instigates sterilization by interfering with bacterial electron transport chain, disrupting both metabolism and energy synthesis. In vitro experiments indicate excellent cytocompatibility of P-bioHJ. Furthermore, in vivo assays demonstrate that P-bioHJ exhibits outstanding antimicrobial properties in a cutaneous infection model with LIU, and promotes angiogenesis and osteogenesis in an infectious bone defect model by decorating with naringin. As envisaged, this work offers valuable insight to augment piezocatalytic therapy by harnessing sonocavitation effect, advancing the remediation of infected tissue regeneration.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"18 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142670716","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}

Molecular hydrides are usually stable under moderate pressure, but the underlying metallization mechanism remains elusive. Here, the important role of chemical interactions in governing the structures and properties of molecular hydrides is demonstrated. A new mechanism is proposed for obtaining high-temperature and even room-temperature superconductivity in molecular hydrides and report that the ternary hydride NaKH12 hosts Tc values up to 245 K at moderate pressure of 60 GPa. Both the excellent stability and superconductivity of NaKH12 originate from the fact that the localized electrons in the interstitial region of the metal lattice occupying the crystal orbitals well matched with the hydrogen lattice and forming chemical templates to assist the assembly of H2 units. These localized electrons weaken the H─H covalent bonds and improve the charge connectivity between the H2 units, ensuring the strong coupling between electrons and hydrogen-dominated optical phonons. The theory provides a key perspective for understanding the superconductivity of molecular hydrides with various structural motifs, opening the door to obtaining high-temperature superconductors from molecular hydrides at moderate pressures.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"31 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665345","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 clinical prospect has not been fully realized due to the scarcity of efficient sonosensitizers. Herein, for the first time a novel Os-doped Au-tri(pyridin-4-yl) amine coordination structure (Os@Au-TPA)-based sonosensitizer is originally designed and synthesized for sono-immunotherapy of breast-metastasized tumors. Impressively, Os@Au-TPA shows much higher US-mediated 1O2-producing activity than Au-TPA as well as the other traditional sonosensitizers, for example, ≈41.6 folds to ce6, 19.5 times to Protoporphyrin IX (PpIX), 12.0 to Indocyanine Green (ICG), and 11.1 to Iron phthalocyanine (Pc(Fe)). The Os@Au-TPA can not only generate abundant ROS upon US irradiation to implement sonodynamic therapy (SDT), stimulating cell apoptosis and further immunogenic cell death, but can also generate O2 to alleviate hypoxia to promote the polarization of M2 to M1 macrophages to enhance tumor immunogenicity. As a result, when combined with PD-L1 antibody, it remodels the immunosuppressive tumor microenvironment, achieves concurrent sonodynamic-triggered immune activation, and eradicates both the original and distant-metastasized tumors efficiently. This work not only provides a new strategy to construct potent sonosensitizers from pyridine-metal coordination structures but also proves that sonosensitizers with high performance are crucial in boosting cancer sono-immunotherapy.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"99 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665387","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 study, a polydentate ligand-regulated dual-surface stress management strategy for perovskite (PVK) is introduced to eliminate tensile strain and interface defects via multidentate anchoring. 3-amino-5-bromopicolinaldehyde (BD) is employed on the lower surface of PVK, while its −CO, −NH2, and pyridine functional groups facilitate the bridging of SnO2 with PVK, alleviating tensile stress and lowering interfacial energy barriers. For the upper surface, the bis−SO2, pyridine, and bis−CF3 functional groups of N-(5-Chloro-2-pyridyl) bis(trifluoromethanesulfonimide) (FC) are utilized to increase the ion migration energy barrier through anchoring, which effectively diminishes tensile stress and defects. Besides, −CF3 also constructs a hydrophobic barrier on the upper surface. Notably, tensile stress successfully transforms into compressive stress based on the dual-surface stress regulation, significantly improving the framework stability of PVK. Consequently, the devices treated with BD and FC achieve an elevated open-circuit voltage of 1.24 V and PCE of 24.70%.
