However, high DN solvents can compromise the intrinsic high-voltage stability (>5 V) of conventional electrolytes due to their limited electrochemical stability. In this study, a novel strategy is presented that utilizes the anion's DN for non-destructive regulation of ionic liquids (IL) to achieve advanced electrolytes at 5.3 V. It is demonstrated that introducing high DN salt anions competes with EMIM+ in EMIM-TFSI, forming strong interactions with EMIM and enhancing the stability of the IL electrolyte. The expelled TFSI− ions tend to coordinate with Li+, facilitating the formation of high-quality solid/cathode electrolyte interphases. Consequently, the Li//NCM622 cells with high DN salt anions (LiClO4-IL and LiOTF-IL) show remarkable capacity retention rates of 93.5% and 94.6%, respectively, after 100 cycles over a voltage range of 2.8–4.7 V. Moreover, the Li//NCM622 cells using LiClO4-IL maintain a capacity retention of 81.6% and an average Coulombic efficiency of 99.4% after 350 cycles at 2.8–4.6 V. The proposed DN tuning mechanism is believed to offers new insights for designing high-energy-density LMBs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"14 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867174","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}

It involves the activation of T cells in vitro via artificial antigen presenting cells (aAPCs). However, conventional aAPC systems face limitations such as poor biodegradability, limited cargo capacity, and complex fabrication procedures. In this context, microcapsule systems offer a promising alternative for creating artificial cells, thanks to their distinctive core-shell architecture and straightforward functionalization. Despite their potential, existing microcapsule systems often rely on toxic chemicals or harsh conditions for fabrication. Inspired by how marine organisms use biomolecules to create silica structure, the study develops a universal biomimetic strategy to fabricate silica microcapsules (SMCs) using emulsion templates under benign conditions. These SMCs are loaded with hydrophobic fluorescent dyes for tracking and magnetic nanoparticles for easy separation and manipulation, and they can be surface-modified with antibodies to function as aAPCs. The novel SMC-based aAPC (SMC-aAPC) demonstrates superior T cell activation compared to commercially available Dynabeads.

In this work, a novel composite regulation-enhanced strategy is proposed to prepare a heterogeneous composite catalyst, FeCoNiCuMn@NC/NiFeCe LDH, exhibiting exceptional bifunctional activity. The catalyst achieves a half-wave potential of 0.905 V for the oxygen reduction reaction and a 266 mV overpotential at 10 mA cm−2 for oxygen evolution reactions. Experimental and theoretical analyses reveal that the heterogeneous interface between FeCoNiCuMn@NC and NiFeCe LDH effectively optimizes the electronic structure of materials by shifting the d-band center closer to the Fermi level. This optimization not only enhances the continuous distribution of electronic density but also improves the adsorption and desorption processes of intermediates, thereby effectively overcoming the trade-off between catalyst activity and stability. When applied in rechargeable ZABs, the catalyst demonstrates remarkable cycling stability over 750 h and a peak power density of 268.5 mW·cm−2.

To this end, this work considers the anisotropic nucleation and growth of reversed polarization along the three principal axes of the orthorhombic phase of HfO2 and ZrO2. This approach differs from the earlier theoretical study that assumed homogeneous switching and predicted too high Ec (≈10 MV cm−1), and from the recent theoretical prediction that assumed domain switching but still predicted unrealistically high Ec. Along the b‐direction involving the non‐polar spacer sub‐unit cell layer, the switching barriers (Ess) for nucleation and growth of a reversed domain are similar. In contrast, along the a‐direction, which lacks a non‐polar layer and is previously overlooked, nucleation affects neighboring polar layers, significantly reducing the Es for growth. Switching types along the c‐direction (homogeneous or stepwise) has little effect on the overall Es. These distinct Es characteristics along three directions predict an Ec of 1–2 MV cm−1 for a 10‐nm‐thick (Hf,Zr)O2 film, consistent with experimental results.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"32 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866710","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, an immuno-bioenergy regulated hydrogel (CCE) is reported, which converts apoptotic cells into cytokines that facilitate tissue repair. The CCE consisted of a poly(citrate-curcumin) and erastin cross-linked thermosensitive network, which enhanced efferocytosis in dendritic cells (DCs) by the sustained release of erastin and reinforced the cellular energy metabolism by intracellular release of citrate. With the promoted efferocytosis and increased secretion of anti-inflammatory and pro-reparative cytokines, macrophages are effectively polarized towards M2 phenotype via activation of JAK1/STAT3 pathway, while the damaged function of fibroblasts and endothelial cells under high-glucose conditions is restored. Moreover, the released citrate increased intracellular citrate level, modulating the high glucose-induced energy metabolites disturbances and alleviating mitochondrial dysfunction in endothelial cells. Notably, this combination exhibited a synergistic effect in promoting endothelial cells angiogenesis and immunoregulation ability of macrophages. In a diabetic wound model, CCE hydrogel facilitated the diabetic wounds repair, characterized by a reduced inflammation, enhanced angiogenesis and collagen deposition. These outcomes are attributed to immune microenvironment reconstruction through enhanced efferocytosis-mediated clearance of apoptotic cells and M2 polarization of macrophages.

The proposed sensor is capable of detecting NO2 gas through the charge trapping and detrapping mechanisms of gas molecules. The unique capability to switch between the transient detection and accumulation recognition modes is achieved via the controlled modulation of electrical bias and ultraviolet light. More importantly, the gate-bias adjustment facilitates precise sensitivity control by regulating the device's electrical properties, while the UV exposure promotes efficient desorption of attached gas molecules.

Reactive oxygen species (ROS) generation platforms have been used to combat biofilm-associated infections. However, biofilm microenvironments (BME) such as hypoxia and overexpressed antioxidants restrict the efficacy of ROS-based therapies. To address the problem, this study incorporates calcium peroxide (CaO2) and berberine (BBR) into Fe and Zn containing bimetal metal–organic frameworks (FZ) to construct a composite ROS nanogenerator (CBFZ), which is able to remodel BME and further promotes ROS generation for enhance biofilm eradication. CBFZ degrades to release CaO2, Fe3+, Fe2+, and BBR in biofilm, where CaO2 decomposes into O2 and H2O2 to relieve hypoxia, and Fe3+ consumes glutathione (GSH). Subsequently, the remodeled BME boosts the ROS production of the O2-dependent BBR-mediated photodynamic therapy and H2O2-dependent Fe2+-based chemodynamic therapy, and the depleted GSH minimizes ROS scavenging in the meantime, ultimately maintaining a high level of ROS in biofilm. It is demonstrated that CBFZ can effectively eradicate biofilm by killing the embedded bacteria and dispersing the biofilm matrix. Moreover, CBFZ exhibits an outstanding therapeutic effect in a murine model with subcutaneous biofilm infection. Overall, this work offers a propagable strategy to enhance ROS-based antibiofilm therapy.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"32 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867176","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}
