Nanocoated bacteria attenuate intestinal mucosal inflammation and recover gut barrier integrity by leveraging the immunosuppressive nature of hyaluronic acid and the butyrate-producing ability of Clostridium butyricum. Nanocoated bacteria also alleviate the interstitial inflammation and pathological damage of extraintestinal organs via remodeling microbial metabolites and decreasing microbial translocation.

Enhancing the mechanical performance of these interfaces, particularly their resistance to delamination, is essential to enable extremely lightweight designs and improve energy efficiency. Improving toughness (or increasing energy dissipation during delamination) has traditionally involved modifying materials to navigate the well-known strength-toughness trade-off. However, a more effective strategy involves promoting non-local or extrinsic energy dissipation. This approach encompasses complex degradation phenomena that extend beyond the crack tip, such as long-range bridging, crack fragmentation, and ligament formation. This work explores this innovative strategy within the arena of laminated structures, with a particular focus on fiber-reinforced polymers. This review highlights the substantial potential for improvement by presenting various strategies, from basic principles to proof-of-concept applications. This approach represents a significant design direction for integrating materials and structures, especially relevant in the emerging era of additive manufacturing. However, it also comes with new challenges in predictive modeling of such mechanisms at the structural scale, and here the latest development in this direction is highlighted. Through this perspective, greater durability and performance in advanced structural applications can be achieved.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"64 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673109","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 tackle these challenges, laser powder bed fusion is utilized to fabricate biodegradable Zn-Li porous scaffolds that supress tumors and promote osteogenesis. After the structure design and composition selection, the Zn-0.8Li porous scaffold with Gyroid unit optimally balances the co-release of Zn2+ and Li+ during degradation, resulting in favorable antitumor and osteogenic effects. In vitro, the Zn-0.8Li scaffold significantly inhibits osteosarcoma progression by suppressing tumor cell proliferation, promoting apoptosis, alleviating migration, and simultaneously promotes osteogenic differentiation through the enhanced expression of osteogenic markers. In vivo, the Zn-0.8Li scaffold inhibits the malignant osteosarcoma behavior and facilitates bone regeneration in areas with bone defects. Transcriptomic analysis further reveals that the simultaneous release of Zn2+ and Li+ from the biodegradable Zn-0.8Li scaffold contributes to anti-osteosarcoma activity by downregulating PI3K/Akt signaling pathways.

Traditional methods like electron beam lithography (EBL) and focused ion beam (FIB) milling, however, suffer from low throughput and high costs. In this paper, a scalable and cost-efficient method is introduced for producing multiplexed plasmonic colors by in situ photoreducing AgNPs within microgel architectures with controlled porosity. Utilizing a digital micro-mirror device (DMD)-based flow microlithography system combined with a programmable dithering-mask technique, the high-throughput synthesis of shape or barcoded microparticles is facilitated, along with large-scale, high-resolution images embedded with hidden multiplexed plasmonic colors. This approach allows for a hidden multiplexed plasmonic color code library, significant enhancing the encoding capacity of barcode microparticles from 33 to 303 (a 1000-fold increase). Additionally, quantitative agreement is achieved between chemically encrypted and optically decrypted plasmonic colors using a deep learning classifier. Moreover, the method also supports the production of large scale (>5.6 × 5.6 cm2), high-resolution (>300 dpi) microgel arrays encrypted with multiple plasmonic colors in under 30 min. The multiplexed plasmonic coloration strategy in microgel architectures paves a new way for hidden data storage, secure optical labeling, and anti-counterfeiting technologies.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"2 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678694","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, an important issue related to structural disorder of superlattices at low temperatures has received little attention to date. In this work, it is shown that CsPbBr3 nanocrystal superlattices undergo a reversible order–disorder transition upon cooling to 90 K. The transition consists of the loss of structural coherence, that is, increased nanocrystal misalignment, and contraction of the superlattices, as revealed by temperature-dependent X-ray diffraction, and is ascribed to the solidification of ligands (on the basis of Raman spectroscopy). Introducing shorter amines on the nanocrystal surface allows to mitigate these changes, improve order, and shorten interparticle distance. It is demonstrated that the low temperature phase of the short ligand-capped nanocrystal superlattices is characterized by a strong exciton migration observable in the photoluminescence decay, which is due to the shrinkage of the inter-nanocrystal distance.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"23 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678702","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, an anisotropic resistive switching cell with a planar configuration based on lithiated NbSe3 nanosheets is demonstrated. Benefitting from the highly aligned diffusive channel associated with a quasi-1D van der Waals structure, the memristor patterned along NbSe3 atomic chains presents robust memory switching behavior with superior stability, particularly the low set/reset voltages (0.4 V/−0.36 V) and extremely small standard deviation (0.041 V/0.051 V), among the best compared to state-of-the-art devices. More importantly, unlike traditional resistive switching materials, anisotropic ion migration in NbSe3 crystals leads to a high orientation selectivity in the conductance update.

Here, an ideal malleable large-deformation metamaterial featuring high-stress levels and stability is reported. A performance-oriented multidimensional performance expansion strategy is adopted to obtain the bionic triangular corrugation-based plate lattice (TCPL) metamaterial. Then, the deformation constraint strategy that TCPL is innovatively used as the main topology with lateral expansion and buckling inhibited by the inserted enhancing topology is proposed, thus obtaining the built-in dual-topology enhanced TCPL (ETCPL). The ETCPL is again substantially strengthened in stress uniformity with almost no gradient and mechanical properties with strain energy improved by 51.56%. They are much more robust than typical multicellular materials, with the largest performance enhancement reaching 18 667.19%. In addition, the strength-density performances of both metamaterials significantly exceed the predictions of Gibson–Ashby model up to 75.2% maximum.
