Here, an injectable carbon dots (CDs)-linked egg white hydrogel was developed, termed TAMs Transform Factory (TTF-L-C), to spatiotemporally manipulate TAMs. The fabricated CDs significantly promoted macrophage migration. Notably, TTF-L-C achieved macrophage spatial enrichment through CDs-induced directional recruitment with molecular Ctnnd1 upregulation. Subsequently, the recruited macrophages were locoregionally reprogrammed within TTF-L-C, as well as blocking the upregulated PD-L1. Finally, through multi-stage regulation at spatial, cellular, and molecular levels, TTF-L-C released immune-activated M1 macrophages to the tumor site as it degraded. Moreover, TTF-L-C promoted dendritic cell (DCs) maturation and further boosted T cell activation, thereby reshaping the tumor-suppressive TME. Through peritumoral injection, TTF-L-C enhanced tumor immunotherapy in both subcutaneous and recurrent 4T1 tumor models with satisfactory biosafety. Therefore, TTF-L-C is proposed to become a safe and powerful platform for various biomedical applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"216 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776011","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, traditional synthesis methods are often associated with high toxicity, energy intensity, and inefficiency. This study introduces an efficient and eco-friendly method for synthesizing glycine via the reductive coupling of oxalic acid and nitrate using a Bi metal catalyst, enhanced by lattice strain from Bi and oxide composites undergoing electrochemical transformation. At an applied potential of −0.76 V versus the reversible hydrogen electrode (RHE), the Bi catalyst achieves an impressive glycine Faradaic efficiency (FE) of 79.1%, yielding a record concentration of 0.17 m, substantially higher than conventional Bi-based systems. Furthermore, the introduction of glycolaldehyde and hydroxylamine as reactants raise the glycine FE to 91.3% with a production rate of 2433.3 µmol h−1 under identical conditions. Electrochemical analysis and theoretical calculations demonstrate that lattice expansion notably boosts glycine synthesis by facilitating NH2OH formation and promoting the efficient reduction of oxime intermediates. These results underscore the significance of lattice engineering in enhancing active site performance and accelerating reaction kinetics, offering a sustainable and efficient alternative to traditional glycine synthesis methods.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"183 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767152","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 solid additive, 1,4-diiodo-2,5-dimethoxybenzene (DIDOB), is developed to improve the photovoltaic performance of OSCs and conduct a comprehensive investigation into its effect on the charge recombination process. As a result, the PM6:L8-BO-X-based binary OSC processed with DIDOB achieves an excellent efficiency of 19.75% with a remarkable fill factor of 81.9%, owing to the optimal fiber network morphology, tighter and ordered molecular packing, as well as the suppression of both bimolecular and geminate recombination. Notably, the DIDOB exhibits broad universality as an additive in other non-fullerene acceptor-based OSCs. Impressively, the D18:PM6:L8-BO-based ternary device processed with DIDOB yielded an excellent efficiency of 20.11% (certified as 20.03%).

Metasurface offers unprecedented control over sensing and wave manipulation, yet a conflict arises in achieving both simultaneously. To solve the problem, a decoupling strategy is proposed to simultaneously realize sensing and wave manipulation using a space-time-coding digital metasurface (STCDM) without integrating any sensors. A space-time-coding matrix is constructed by allocating the reflectivity of all meta- atoms across the space-time dimensions, enabling arbitrary manipulation of EM waves while simultaneously acquiring the sensing information at the incident frequency from metasurface. Excellent accuracy of direction-of-arrival estimation and wave manipulation confirms the decoupling method. An adaptive STCDM system is built up to validate the strategy in wireless communications. The measured results show that the adaptive STCDM enables independent sensing and wireless communications at the same time for targets located at different positions without integrating any sensors. The proposed method may find potential applications in wireless communication, radar, and Internet of Things systems.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"58 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767156","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 chiral crystals showed high sensitivity to the handedness of circularly polarized pump light (gSHG − CD ≈ 9% at 1510 nm). The THG response shows resonance enhancement matching the excitonic absorption. Achiral (Rac-MBA)4Bi2I10 exhibits the maximum THG response (χ(3) = 1.05 × 10⁻¹⁸ m2 V−2).

In this work, hyaluronic acid modified zinc-copper bimetallic peroxides (ZCPO@HA) nanoparticles are synthesized through a one-step symbiotic method by co-hydrolysis of zinc acetate and copper acetate in weakly alkaline solution, followed by modification with sodium hyaluronate. Upon decomposition in the tumor microenvironment, ZCPO@HA nanoparticles can generate a considerable content of hydroxyl radical (·OH) by Fenton-like reaction between Cu2+ and self-compensating hydrogen peroxide, while downregulating the expression of glutathione peroxidase 4 to induce ferroptosis. The abundant release of Cu2+ leads to the aggregation of dihydrolipoamide S-acetyltransferase and the reduction of iron-sulfur cluster proteins, causing cuproptosis. The immunogenic cell death of tumor cells releases abundant damage associated molecular patterns, effectively activating the adaptive immune response. Zn2+ and ·OH cause mitochondrial damage, leading to the release of a substantial amount of mitochondrial DNA. This subsequently activates the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (cGAS-STING) pathway, enhancing the innate immune response.
