Here, a simple strategy is introduced that utilizes charge repulsion between graphene oxide (GO) and engineered bacteria to induce liquid crystal formation, enabling their layer-by-layer self-assembly on a polyethersulfone membrane. The interlayer pressure flattens the bacteria, removing interlayer water and forming a densely packed structure. This compression decreases the spacing between functional groups, leading to a robust hydrogen bonding network and a significant enhancement in mechanical properties (12.42 times tensile strength increase). Notably, the pressure preserves the activity of the super uranyl-binding protein of engineered bacteria, which selectively coordinates with uranyl (UO22+) through high-affinity coordination bonds, enabling recognition and sieving of target ions. The membrane demonstrates near 100% rejection of UO22+, K/U, and V/U selectivity of ≈140 and ≈40, respectively, while maintaining long-term stability. This strategy provides a versatile platform for the precise design of high-performance membranes, advancing the field of molecular transport in energy and environmental applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"28 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401641","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}

Unlike luminescent HPs with band-edge emission, trivalent rare-earth (RE) ions typically emit low-energy light through intra-4f optical transitions, characterized by narrow emission spectra and long emission lifetimes. When fused, the cooperative interactions between HPs and REs endow the resulting binary composites not only with optoelectronic properties inherited from their parent materials but also introduce new attributes unattainable by either component alone. This review begins with the fundamental optoelectronic characteristics of HPs and REs, followed by a particular focus on the impact of REs on the electronic structures of HPs and the associated energy transfer processes. The advanced synthesis methods utilized to prepare HPs, RE-doped compounds, and their binary composites are overviewed. Furthermore, potential applications are summarized across diverse domains, including high-fidelity anticounterfeiting, bioimaging, LEDs, photovoltaics, photodetection, and photocatalysis, and conclude with remaining challenges and future research prospects.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"62 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401645","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}

Herein, two novel trimetallic MAu18Cd3 (M = Pd/Pt) NCs that are derived from M-doped Au25 templates of MAu24 are reported, in which the central doping of M atom and the surface-motif doping of Cd atoms are concurrently achieved. Compared to the original templates, Cd-induced surface engineering enhances the rigidity of the structural framework and enlarges the HOMO-LUMO gaps of the MAu18Cd3, significantly improving photoluminescent efficiency by suppressing nonradiative relaxation. The critical role of the central M (Pd/Pt) dopant in photoluminescence, which regulates the rate of radiative decay of excited-state electrons, has also been substantiated. More notably, the doped case of PtAu18Cd3 exhibits excellent photoinitiation activity in 3D two-photon printing with a high resolution of ≈140 nm, which may be attributed to the prolonged excited state. Overall, this work provides a generalized routine for the precise synthesis of multi-metal NCs with concurrent enhancements in photoluminescence and photoinitiation activity, which is expected to stimulate further research for the design and preparation of multi-functional, multi-metal NCs.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"29 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401640","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, non‐destructive, real‐time monitoring is lacking, as traditional methods are often costly, destructive, and low‐throughput. In this article, a non‐destructive chemical tomographic strategy is presented for decoding cyto‐proteo‐genomics of organoid using volatile signaling molecules, hereby, Volatile Organic Compounds (VOCs), to indicate metabolic activity and development of organoids. Combining a hierarchical design of graphene‐based sensor arrays with AI‐driven analysis, this method maps VOC spatiotemporal distribution and generate detailed digital profiles of organoid morphology and proteo‐genomic features. Lens‐ and label‐free, it avoids phototoxicity, distortion, and environmental disruption. Results from testing organoids with the reported chemical tomography approach demonstrate effective differentiation between cyto‐proteo‐genomic profiles of normal and diseased states, particularly during dynamic transitions such as epithelial‐mesenchymal transition (EMT). Additionally, the reported approach identifies key VOC‐related biochemical pathways, metabolic markers, and pathways associated with cancerous transformations such as aromatic acid degradation and lipid metabolism. This real‐time, non‐destructive approach captures subtle genetic and structural variations with high sensitivity and specificity, providing a robust platform for multi‐omics integration and advancing cancer biomarker discovery.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"208 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143393204","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}

While the working mechanisms of high‐volatility single‐ring additives have been well studied, the influence of low‐volatility fused‐ring VSAs on molecular aggregations and exciton/carrier dynamics remains still unclear. Herein, 3,6‐dibromothieno[3,2‐b]thiophene (3,6TTBr) is selected as a representative low‐volatility fused‐ring VSA to elucidate its working mechanism. Via the theoretical and experimental joint investigation, it is found that rigid and planar 3,6TTBr molecules adsorb onto the terminal units of L8‐BO (acceptor), inducing loose space for adjacent molecules. The low‐volatility 3,6TTBr thus favors the L8‐BO center‐terminal packing with a larger interfragment distance, which relieves the L8‐BO over‐aggregation and induces the ordered packing. Consequently, the 3,6TTBr treatment reduces aggregation‐caused quenching, enhancing the photoluminescence quantum yield and exciton lifetime of L8‐BO film. The combination of the above properties with the reduced trap density and improved carrier transport in the 3,6TTBr‐treated devices contributed to PCE of 20.1%. To validate the broad applicability of the findings, 1,5‐dibromonaphthalene (1,5‐BN), another low‐volatility fused‐ring solid, is explored. The devices with 1,5‐BN achieved an impressive PCE of 20.5%, verifying the validity of the low‐volatility fused‐ring VSA strategy for boosting OSC performances.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"160 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143393207","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}

Herein, the ordered PtCo intermetallic is reported with a Pt‐rich shell loaded on a highly graphitized carbon carrier (O‐PtCo@GCoNC) prepared by an impregnation annealing strategy. Systematic X‐ray spectroscopic, operando electrochemical techniques and theoretical calculations reveal that thanks to the synergistic interaction of the core–shell PtCo intermetallic structure with a tailor‐made Pt electronic configuration and highly graphitized carbon, O‐PtCo@GCoNC exhibits significantly enhanced activity and stability toward ORR. Crucially, O‐PtCo@GCoNC delivers a much‐enhanced mass activity of 0.83 A mgPt−1 at 0.9 V versus reversible hydrogen electrode (RHE) in 0.1 m HClO4, which only drops by 26.5% after 70 000 cycles (0.6–1.0 V vs RHE), and 10.8% after 10 000 cycles (1.0–1.5 V vs RHE), apparently overmatching Pt/C (0.19 A mgPt−1, 73.7%, and 63.1%).

The co‐delivery of melanoma‐associated peptide antigens by the nanoconjugate platform induced significant effector immune responses in a mouse melanoma model. The nanoconjugate platform synergized with a PD‐1 inhibitor to revert the immunosuppressive melanoma tumor microenvironment by improving cytotoxic T‐cell infiltration, which prompted a superior anti‐tumor effect with prolonged overall survival without acute organ toxicity.
