Here, a metal-free carbonaceous material—that is, biomass substrate 5-hydroxymethylfurfural-derived graphene-like nitrogen doped porous carbon sheet (GNPCH)—and its application as a new catalyst for electrochemical FDCA synthesis is presented. The study scrutinized the catalytic principles, demonstrated the surprising robustness, and explored the origin of the high efficiency of GNPCH catalyzed electro-synthesis of FDCA. Initially, facial pyrolysis of 5-hydroxymethylfurfural and urea forms ultrathin GNPCH with rich micropores and defects. By employing GNPCH-900 catalyst, stable, continuous operation of >400 h with both FDCA yields and Faraday efficiencies >90% is achieved; those values not only represent the best metal-free catalyst and that are comparable to those of the state-of-the-art metal-based counterparts, but also showcase one of the longest-running electrochemical FDCA synthesis reactions. A series of electrochemical measurements, in situ characterization, and density functional theory calculations indicate that the origin of the high efficiency is mainly from the pyridinic-N-related active sites and clarify the reaction pathway. These findings suggest that the GNPCH catalyst will be a potential alternative to the metal-based catalysts in electrochemical biomass valorization.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418014","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, the extensive use of fluorides poses severe environmental concerns. In this study, a novel strategy is proposed to construct a Li3N/Li2O heterostructure via the in situ decomposition of lithium perchlorate (LiClO4) and lithium nitrate (LiNO3), replacing the role of LiF in the SEI. This unique heterostructure combines excellent lithium-ion transport capability with robust electronic insulation properties, effectively preventing electron tunneling phenomena. When paired with the NCM811 cathode, the Li||NCM811 full cell exhibits exceptional electrochemical performance, including outstanding charge–discharge capabilities under extreme temperatures. At 60 °C and 1C conditions, the battery retains 82.11% of its capacity after 500 cycles; at 25 °C and 1C, it maintains a capacity retention rate of 80.61% after 800 cycles. Furthermore, under practical application conditions (100 µm lithium anode, N/P ratio of 3.09, and a 1.5 Ah pouch cell), the fluorine-free lithium metal battery (LMB) retains 77.93% capacity after 100 cycles, demonstrating the superiority and practical value of this strategy.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"23 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401217","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}

Donor–acceptor conjugated polymers hold particular appeal for SF and photovoltaic applications, yet such type SF materials remain largely unexplored, and the previously reported systems are usually beset by low triplet energy and short multiexciton (ME) lifetime impeding their practical applications. In this work, a donor-π-acceptor design strategy is presented and successfully develop a new practical polymer SF system. The comprehensive spectroscopic analyses clearly validate that such a molecular design enables the polymer system to hold suitable triplet energy of 1.0–1.1 eV and long ME lifetime of ≈600 ps and implement ultrafast and quantitative ME generation in both dilute solution and solid aggregates. These merits, along with the good processability and excellent stability, make such polymer systems particularly well-suited for SF-based light harvesting applications. These results highlight the practical polymer SF system and feasible design guidelines, which can not only pave the way to the discovery of rare polymer SF materials but also lay the foundation for the further implementation of highly efficient SF-based photovoltaic devices.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"82 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401218","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}

Achieving this actuation requires precise mesogen alignment before crosslinking. Magnetic field alignment offers an advantage over other techniques as it enables volumetric mesogen alignment. However, magnetic alignment has to be performed in the state where mesogens exhibit anisotropic diamagnetic properties suitable for alignment, typically in the nematic phase. Therefore, it is difficult to obtain a stable nematic liquid crystalline mixture before crosslinking, while preventing mesogen recrystallization. To address this challenge, a method using a magnetic field assisted thio-Michael polyaddition followed by the photo-crosslinking of liquid crystal oligomers (LCOs) is presented. This process is straightforward and allows the synthesis of magnetically aligned high molecular weight LCOs, which maintain a nematic phase before crosslinking. By applying different magnetic field orientations during the polyaddition, three distinct LCE networks are synthesized, each demonstrating unique reversible deformation behaviors, including radial contraction and expansion, thickness contraction, and bending. The potential of this approach is further demonstrated with LCE-based four-leaf clovers exhibiting selective and reversible large-angle bending deformation, despite the high thickness of the material. This simple approach should help researchers in various fields looking for a practical and versatile method for designing robust LCE actuators.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"16 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401223","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}

Insufficient available data is the first one, which is exacerbated by a large amount of censored information, thereby obstructing the effective employment of this data for accurate predictions. Second, lung cancer patient survival data often exhibit complex temporal feature associations, suggesting patient-specific traits on survival outcomes. To address these issues, the dataset are augmented by integrating semi-supervised learning, which allows for more effective use of the event data and mitigates overfitting issues. Subsequently, a Transformer-based predictive model is developed, trained by assorted survival time groups, intending to expand the comprehension of data feature associations. The accuracy of the proposed model is meticulously assessed using a variety of validation metrics, including the Time-dependent C-statistic, Integrated Brier Score (IBS), the Time-dependent receiver operating characteristic (ROC) curves, and survival curves. These rigorous evaluations offer an intricate insight into the model's performance across different time intervals and event occurrences, thus obtaining a holistic comprehension of the model's precision. The experimental findings convincingly demonstrate the superiority of the proposed framework compared to state-of-the-art methods.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"66 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401215","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}
