There is an urgent demand for a system that incorporates neuromorphic environmental information encoding, synaptic signal processing, and motion control. Taking inspiration from the polychromatic visual system, it is initially employed bulk heterojunction organic photosynapses (BHJ‐OPS) to replicate the functionalities of human‐like visual nerve system. The BHJ‐OPS, utilizing a two‐terminal architecture, exhibits an ultra‐broadband photodetection range (365–1060 nm). For near‐infrared (NIR) perception, an optical energy consumption as low as 0.2 fJ per synaptic event is demonstrated, which is the lowest energy consumption achieved so far with NIR light stimulation. By combining the photovoltaic effect in heterojunctions with electron trapping in the buffer layer, BHJ‐OPS displays bio‐synaptic characteristics such as short‐term and long‐term memory, as well as experiential learning, which endows the synapse array with multispectral color‐discrimination capabilities. Finally, it is implemented miniature insect robots capable of night‐time foraging and predator evasion based on a simulated 26 × 26 memristor network. This demonstrates significant potential for the development of miniature insect robots with self‐regulation and adaptability, particularly in exploration, monitoring, and rescue missions.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"1 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237774","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, a pre-SEI is designed by a potentiostatic controlling electrolyte decomposition method to reduce Li loss for SEI formation and smooth Li deposition/dissolution behavior. When holding the potential at 0.5 V, the electrolyte additive ethoxy-pentafluoro-cyclotriphosphazene (PFPN) and lithium salts simultaneously decompose to form a dense double-layered pre-SEI with high ionic conductivity, enabling fast Li+ transport across the interface and suppressing the following Li loss of building SEI. As a result, a high initial CE (ICE: 95.5%) and stable CE of 98.7% in Li|Cu cells are achieved, which is a 12.7% and 0.7% improvement compared with the counterpart without pre-SEI. Moreover, the cycling life of the assembled AF-SSLMB pouch cell (Cu||LFP) with pre-SEI is prolonged by 5 times, with a capacity retention rate of 44.9% after 100 cycles. This work provides a scalable strategy to reduce Li loss for both building SEI and following the Li plating/stripping process in AF-SSLMBs.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"36 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237974","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, Monodispersed Os-O-Co modules are constructed within a cobalt hydroxide structure via an in situ osmium (Os) single-atom modification strategy to serve as a bifunctional catalyst. The d-p orbital hybridization in the structure shifts the d-band center of Os sites away from the Fermi level, weakening the adsorption energy of reaction intermediates and exhibiting the lowest N─H dehydrogenation energy barrier for HzOR and moderate active hydrogen adsorption energy for hydrogen evolution reaction (HER). When integrated into a membraneless flow cell (MFC), the catalyst demonstrates exceptional performance in HzOR-SWE, requiring only 0.768 V to deliver 1.0 A cm−2 with a remarkable rate of 31.9 moles of hydrogen per kilowatt-hour (kWh). This represents a 70.7% energy saving compared to conventional seawater splitting systems (2.62 V, 7.6 kWh mol−1).

Herein, a new DNA logical processing strategy is explored for selective cell engineering and to develop a feasible technology for precise cell identification. Specifically, this cell identification technology accomplishes logical engineering through the employment of cell surface-confined DNAzyme coordination, which not only enables the labeling of versatile DNA probes at specific cells but also avoids false-positive outputs caused by the neighboring non-target cells. In proof-of-principle studies, this cell identification technology achieves precise magnetic isolation and electrochemical determination of specific cancer cells (i.e., stem cell-like subpopulations in breast cancer). When further applied to tumors taken from mouse models, this technology exhibits accuracy comparable to that of flow cytometry; however, it is simple to operate and offers superior recognition capabilities for revealing multiple biomarkers. More importantly, this cell identification technology can be successfully applied in tumor tissues from breast cancer and lung cancer patients, demonstrating satisfactory practicability. Therefore, this work may provide new insights for the precise identification of cells, especially cancer cells, and is expected to offer technical support for clinical diagnosis and related biomedical research.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"134 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237937","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}

Here, this work develops directly evolved biovesicles as biological clock-modulated nanovaccines (Clock-NVs) to augment circadian clock gene expression and enhance cancer immunotherapy. These biovesicles act as bioreactors, transforming an unfavorable factor, ROS, into a beneficial circadian clock enhancer, oxygen. By targeting HIF-1α-BMAL1 axis, Clock-NVs restore the disrupted circadian rhythm within tumors. Upregulation of the core clock gene, BMAL1, initiates tumor cell death, enhances mitochondrial metabolism and antigen processing in dendritic cells to amplify antitumor immune responses. Clock-NVs effectively inhibit tumor growth, diminish metastasis, and demonstrate robust antitumor activity in a model of chemotherapy-resistant senescent tumors. Notably, Clock-NVs combined with adoptive T cell-based therapies achieve a 60% regression of primary tumors, while their use with anti-PD-L1 results in 100% inhibition of tumor recurrence. This strategy introduces nanovaccines designed to enhance temporal immunotherapy by precisely restoring the suppressed rhythm gene expression within tumors.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"1 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237972","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}
