On the contrary, the layer-by-layer (LBL) structure gives a p-i-n separation where the donor is close to the transparent electrode while the acceptor is close to the reflective electrode, which shows to be an ideal structure for OSCs. In this work, volatile solid additives 2,5-dibromoprazine (DBP) and 2-bromine-5-iodopyrazine (BIP) are introduced to regulate the morphology of LBL active layers. Comprehensive morphology analysis reveals that DBP and BIP can promote stronger molecular packing and crystallinity of the acceptor BTP-eC9, resulting in higher charge mobility, more efficient charge separation, and suppressed bimolecular recombination to significantly improve device filling factor (FF), especially in LBL devices. Consequently, by combining layer-by-layer engineering and solid additive BIP, an outstanding power conversion efficiency (PCE) of 19.63% based on the PM1/BTP-eC9 is achieved and further applied to the PM1/BTP-eC9:eC9-2Cl ternary system, the PCE exceeded 20%. The results provide comprehensive insights into the synergistic effect of LBL engineering and additives for high-performance organic photovoltaics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"7 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867114","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}

ISPVA improves the linearity and symmetry of resistive switching, enabling accurate representation of up to 6‐bit states and ensuring precise transitions between low and high resistance states. Additionally, ISPVA ensures consistent current states across different layers, thereby improving electrical response uniformity and enhancing the performance of multilayer structures for high‐density applications. These improvements provide a stable memory window and guarantee the device's endurance for up to 1000 cycles. This study further demonstrates the implementation of various synaptic memory functions, including spike‐time‐dependent plasticity (STDP), spike‐number‐dependent plasticity (SNDP), spike‐amplitude‐dependent plasticity (SADP), spike‐duration‐dependent plasticity (SDDP), and spike‐rate‐dependent plasticity (SRDP). The findings also demonstrate that nociceptive and Pavlovian characteristics can be achieved for on‐receptor computing and associative learning. By integrating ISPVA and advanced fabrication techniques, VRRAM devices can effectively address challenges such as device‐to‐device variability and stochastic properties, thereby establishing a new benchmark for next‐generation computing and memory technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"53 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866661","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 HS‐PD hydrogel utilizes the oxidizing properties of pyrogallol to modulate its electroconductivity (ΔR decreased by ≈78.1%) and mechanophysical properties under normoxic conditions while enabling naked‐eye detection via visible color changes. Moreover, in vitro mechanophysical and electrical changes are evidenced by an increase in stretchability and compression modulus, alongside reduced electrical resistivity under normoxic conditions, as confirmed using C2C12 and 3T3‐L1 cell models. Additionally, in vitro gene expression analysis shows significant downregulation of SOD2, Hif‐1α, and MuRF‐1 genes associated with muscle degradation, indicating enhanced ROS scavenging and potential oxygen normalization in ischemic regions.

However, hetero-structured fillers are usually disorderly distributed in the polymer matrix, hindering the further improvement of the efficiency of constructing thermal conduction pathways in polymer composites. This work proposes a new strategy to graft polymethyl methacrylate molecular brushes on the surfaces of fluorinated graphene@carbon nanotube (FG@CNT) hetero-structured thermally conductive fillers by atom transfer radical polymerization. FG@CNT is orderly arranged and presents the liquid crystalline state (LC-(FG@CNT), which is then introduced into the liquid crystalline polyimide (LC-PI) matrix with high intrinsic thermally conductivity to fabricate LC-(FG@CNT)/LC-PI thermally conductive composite films. The in-plane and through-plane thermal conductivities (λ∥, λ⊥) of 15 wt.% LC-(FG@CNT)/LC-PI films reach 5.66 and 0.76 W·m−1·K−1, respectively, which are 168.2% and 137.5% higher than those of the LC-PI films (λ∥ = 2.11 W·m−1·K−1, λ⊥ = 0.32 W·m−1·K−1), also significantly higher than those of 15 wt.% FG@CNT/LC-PI composite films (λ∥ = 4.72 W·m−1·K−1, λ⊥ = 0.74 W·m−1·K−1).

However, their energy density remains limited due to the lower electrode capacitance and narrower voltage window of conventional symmetrical micro-supercapacitors (SMSCs). In this study, a novel strategy is presented to maximize the energy density of MnO2-based SMSCs by modulating their electrode polarity and redox activity. Specifically, the non-lattice oxygen concentration in MnO2 is focused on tuning to introduce additional redox-active sites, thus improving charge storage capacity and energy density. Using operando electrochemical quartz crystal microbalance (EQCM) analysis reveals a multi-step redox mechanism involving lattice water-assisted transformations and non-lattice oxygen pathways, providing unprecedented insights into MnO2’s electrochemical behavior in alkaline electrolytes. The engineered symmetric MnO2 MSCs achieve an outstanding energy density of 33.63 µW h cm−2 at a power density of 1.12 mW cm−2, retaining full performance under mechanical deformation. The alkaline electrolyte further inhibits disproportionation reaction, preserving active material integrity and cycling durability.
