However, present LMBs still mainly rely on conventional lithium-ion batteries (LIBs) cathodes (e.g., LiFePO4 and LiNi1/3Mn1/3Co1/3O2) with limited reversible capacity (≈150 to ≈190 mAh g-1 cathode), necessitating the paradigm to achieve a new host with abundant Li+ accommodation sites. Herein, it is proposed a high-capacity amorphizing iron molybdate cathode a-Fe2(MoO4)3 (a-FMO), which can reversibly unlock Fe3+/Fe2+ and Mo6+/Mo4+ redox insertion reactions in the metastable structure. Different from its parent crystal and stoichiometric oxides mixtures, a-FMO, with its inherent metastable structure, can not only augment the lithium storage capacities with fully activated redox centers, but also attenuate the lattice confinements for Li+ ion migration. Consequently, the in-situ generated a-FMO electrode exhibited a notable reversible capacity of 254 mAh g-1 with stable cycling over 500 cycles. It endowed a specific energy density of 597 Wh kg-1 and all-climate adaptability over 60 to -40 °C benefited from the amorphizing nature, as well as negligible capacity degradation when cycling at -30 °C. The identification of local structure evolutions and multiple-redox activations in amorphizing materials broadens the scope for designing high-energy-density cathodes.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"5 1","pages":"e07840"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669529","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}

Solution processing enables the formation of electronically active percolated networks by leveraging van der Waals (vdW) interactions between individual 2D nanosheets. While effective vdW interactions are expected to minimize potential energy barriers and contact resistances between nanosheets, undesired residues from material synthesis or device fabrication processes may remain at the interface. In particular, the ideal solvent candidates for optimizing the stability of 2D dispersions are typically difficult to remove due to their high boiling points and exhibit environmental toxicity. Additionally, conventional patterning processes require multiple solvents, which can disrupt vdW interfaces and degrade device performance. To address these challenges, a comprehensive process that combines 2D dispersion preparation with a cross-linker-based direct photopatterning technique is developed using an eco-friendly green solvent. To enable this process, the stability of 2D nanomaterials and ultraviolet light-sensitive cross-linkers is thoroughly analyzed using Hansen solubility parameters. The developed process successfully enables the preparation of stable dispersions of cross-linkers and 2D nanomaterials, including graphene, molybdenum disulfide, tungsten diselenide, and hafnium disulfide, which can then be assembled via vdW interactions to create large-scale functional electronic devices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"22 1","pages":"e05917"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669603","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}

This study presents an innate immunity-guided, macrophage (MΦ)-homing nanoplatform that enables oral delivery of theranostic agents to PDAC lesions by harnessing the migratory behavior of endogenous MΦ toward tumor-derived immune cues. The nanoplatform integrates a βGlus-R848 prodrug-constructed by conjugating β-glucans (βGlus) with the immunomodulator resiquimod (R848) via a reactive oxygen species (ROS)-responsive thioketal linker-and Ag2Te quantum dots (QDs) for near-infrared II (NIR-II) imaging, forming βGlus-R848/Ag2Te nanoparticles (NPs). Upon oral administration, βGlus facilitates the selective uptake of NPs by intestinal MΦ (βGlus-R848/Ag2Te NPs@MΦ), which subsequently migrate to the tumor microenvironment (TME). There, elevated ROS levels trigger the release of R848, reprogramming tumor-associated MΦ from an immunosuppressive M2 to an immunoactive M1 phenotype. This immune activation remodels the stroma, enhances T cell infiltration, and transforms the TME into an immunoactive state, thereby improving therapeutic outcomes. Concurrently, Ag2Te QDs enable deep-tissue NIR-II imaging for real-time visualization of PDAC progression, liver metastasis, and treatment response. Guided by innate immune signals, this MΦ-homing theranostic platform offers a promising strategy to overcome current challenges in PDAC treatment by integrating targeted immunotherapy with noninvasive, real-time disease monitoring.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"26 1","pages":"e07607"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669519","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 design principle of nature-inspired particles originates from the unique chemical and topological characteristics of natural prototypes including biomolecules (proteins and nucleic acids), subcellular particles (virus, extracellular vesicles (EVs), bacteria, and platelet), cells (erythrocyte, sperm cell, immune cell, and pollen), creatures (urchin and hedgehog), and minerals (zeolites). Various preparation methods have been developed to replicate the intricate features of these prototypes. These nature-inspired particles have demonstrated effectiveness in bioanalytical applications, such as i) adsorption, separation, and removal of biological molecules, ii) interaction, recognition, and capture of biological particles, iii) biological sensing, and iv) biological imaging.

This study focuses on Li3PS4-xLiBH4 (LPSBH), a sulfide-based SE with an argyrodite structure, synthesized by mechanical milling. Although LPSBH is known for its high ionic conductivity, its mechanical properties are not thoroughly examined. Here, the deformability of LPSBH is evaluated by demonstrating that it can be formed at low pressures to achieve high relative density. A quantitative evaluation of the AM-SE interfacial contact using symmetric cells demonstrates the formation of a good AM-SE interfacial contact within the electrode layer. A 13 mAh-class laminated cell with LPSBH stacked onto the negative electrode achieves 6C charging at 25 °C under a low stacked pressure of 5 MPa, along with significant cycle stability, which retains ≈70% capacity after 1000 cycles under 1C/1C conditions.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"94 1","pages":"e07963"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669527","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 overcome these bottlenecks, the volume expansion resistance and electrogenic Na+ transport functions of common rain frog (Breviceps adspersus) epidermis are introduced into the design philosophy of stress buffers for SiOx electrodes. Thereupon, a mechanically robust, piezoelectric (MP) stress buffer layer comprised of ferroelectric tetragonal BaTiO3 nanoparticles and a novel homopolymer (PCM) binder of cyanoethyl carbamate-containing methacrylate is developed. It is demonstrated that MP stress buffer layer with superior mechanical properties effectively inhibits excessive volume expansion and stabilizes the solid electrolyte interface along with much suppressed electrolyte decomposition. Meanwhile, MP stress buffer layer helps expedite the dealloying reaction kinetics of SiOx electrodes in half-cells, mainly owing to the generation of a stress-induced built-in electric field within MP stress buffer layer, conducive to improving battery rate performance. As a result, unprecedented cycling and rate performance can be realized in coin and home-made soft package cells with SiOx and SiOx/graphite composite electrodes.
