Via first-principles calculations, it is demonstrated that an enhanced ferromagnetic superexchange interaction between the d orbital is achieved through a salient overlap onto the molecular frontier orbitals of the Cp ligand, producing a room-temperature TC. The (Cr3As2)2Cp3 clusterphene characterizes an ideal XY ferromagnet and a giant magneto band-structure (GMB) effect.

Here, a direction-decoupled light-emitting metasurface (LEM) is originally demonstrated to display dual-channel independent incoherent-emission images based on guided-PL manipulation. Utilizing the wavevector differences of guided-PL between opposite pumping directions, the LEM is designed to enable selective unidirectional emission, thereby decoupling the directional freedom for PL multiplexing and realizing dual meta-display. Besides, the direction-multiplexed LEM can be integrated simultaneously with pumping-light holography for multi-dimensional meta-display.

Herein, a facile method is presented for fabricating self-supporting anodes and cathodes for quasi-solid-state asymmetric supercapacitors (QASCs) by hydrothermally reacting 2-thiobarbituric acid (TBA) with Fe foam (IF) and Co foam (CF), yielding FeTBA4/FeOOH/IF and Co9S8/CF electrodes, respectively. Due to the perfect match between the two electrodes, the redox-active TBA ligands in FeTBA4, the 2D ultrathin nanosheet structure of FeTBA4/FeOOH/IF, and multiple pairs of reversible redox reactions for suppressing water splitting, the configured Co9S8/CF//FeTBA4/FeOOH/IF QASC device delivers outstanding performance. The device possesses a wide operating voltage window of 1.6 V, leading to a high energy density of 82.64 Wh kg−1 at 486.38 W kg−1 and an equally impressive 35.36 Wh kg−1 at 4595.92 W kg−1. Furthermore, a 98.5% capacitance retention is realized after 10000 charging–discharging cycles. Impressively, density functional theory (DFT) calculations reveal the unique pseudocapacitive reactions on the surface of Co9S8/CF and FeTBA4/FeOOH/IF electrodes. Importantly, this work guides the development of high-energy-density supercapacitors via the matching of electrodes and the use of redox-active complex electrodes.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"11 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673680","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, synthetic hydrogels commonly show formula-dependent mechanical properties to fulfill the requirements of mechanical elasticity, stiffness, toughness, and tearing-resistance for adapting to complex application scenario. Inspired by heterostructures and materials found in nature such as leaves and insect wings, a sequential photopolymerization process combined with site-selective patterning exposure is reported to prepare programmable hydrogels with locally heterogeneous reinforcement skeletons, i.e., interpenetrating double networks. The heterogeneous interface between soft matrices and stiff skeletons is seamlessly interlocked through strong multiple hydrogen bonds induced by phase transition. By harnessing the size, shape, and distribution of the patterned stiff skeletons, a wide range of mechanical properties of hydrogels including modulus (0.32–5.92 MPa), toughness (0.15–18 kJ m−2), dissipated energy (1–100 kJ m−3), impact resistance, and mechanical anisotropy can be readily sculpted within one material system without needing design and optimization of the complex and elusive material formulation on demand.

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.

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}
