Nonetheless, the distinctive characteristic is attainable only with PDs crafted via the polar crystallographic axis direction. This constraint directly results in the reported SC-based photopyroelectric PDs being uniaxial, thus elevating the intricacy and expense in manufacturing devices. Herein, a multi-axis SC-driven broadband PD is realized, employing the ferro-pyro-phototronic (FPP) effect in a biaxial ferroelectric EA4Pb3Cl10 (1, EA = ethylamine). In detail, the pyroelectric coefficients of 1 along the c- and b-axis are ≈ 2.6 × 10−3 and ≈ 3.5 × 10−3 µC cm−2 K−1, respectively, comparable to those of conventional pyroelectric materials like PVDF (≈ 2.7 × 10−3 µC cm−2 K−1). Importantly, this device surpasses its inherent optical bandgap to allow for a broad response from UV (UV, 266 nm) to near-infrared (NIR, 980 nm) wavelengths along both axes at zero bias. Such advancement signifies a major progress in the realm of SC-based multidirectional photopyroelectric detection, complete with broadband response.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"12 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857462","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}

MiR-455-3p has been identified as a promising therapeutic candidate to maintain cartilage homeostasis. However, clinical application of free miR-455-3p is limited by rapid degradation, poor targeting efficiency, and off-target effects. To overcome these limitations, an injectable nanocomposite hydrogel-based miRNA delivery system consisting of a cartilage affinity nanocarrier (CANC) encapsulated within a PCL-b-PEG-b-PCL hydrogel is developed. The CANC is formulated using 50% PEGylated G5 PAMAM dendrimers to load miR-455-3p and is further modified with chondrocyte-affinity peptides (CAP) and minimal “self” peptides (MSP) to enhance cartilage targeting and evade macrophage uptake. In vitro studies demonstrated that it exhibited excellent stability, low cytotoxicity, superior cartilage penetration and chondrocyte targeting. Moreover, in vivo experiments in miR-455-3p knockout mice and a destabilization of the medial meniscus (DMM) induced KOA model confirmed that the sustained release and targeted delivery of miR-455-3p effectively rescued cartilage degeneration and prevent KOA progression. Notably, the nanocomposite hydrogel demonstrated high biocompatibility without observed cytotoxicity in major organs. This study highlights the therapeutic potential of the nanocomposite hydrogel miRNA delivery system in promoting cartilage regeneration and presents a promising approach for the development of disease-modifying osteoarthritis drugs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"15 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857463","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 CdS-protected CsPbX3:Mn (X = Cl, Br) halide perovskite (CPCBM/CdS) quantum dots (QDs) with a core/shell structure are prepared for the first time. This advancement not only addresses the challenge of the inherent water instability of perovskites but also imparts spin-related charge-transfer properties to the composite material. Additionally, a simple magnetic stimulation method is employed to rearrange the spin electron occupation in perovskites, effectively enhancing the charge separation efficiency in paper-based PEC (µ-PEC) sensing systems. The underlying mechanism is systematically investigated using density functional theory simulations and ultrafast transient absorption spectroscopy. These studies revealed a spin-dependent reaction pathway and the carrier lifetime extended to 4244 ps under a magnetic field (MF), which is 2.2 times longer than that of the pristine perovskite. As a proof-of-concept application, a µ-PEC sensor is developed for sensitive POC monitoring of ACE in environmental samples with a low detection limit of 23 fm.

However, the synthetic hydrogels are often plagued by loose or inhomogeneous network structures. Herein, a strategy is presented to produce a dense and homogeneous network hydrogel. It introduces an energy dissipation mechanism by constructing a DN, followed by annealing to optimize the polymer network. The prepared hydrogel exhibits superb mechanical properties, including tensile strength (53.0 ± 5.0 MPa), fracture strain (1374 ± 104%), and toughness (315.7 ± 28.4 MJ m−3). Moreover, it can also exhibit similar mechanical properties underwater. Thanks to the conductive ions, the hydrogel is functionalized to have electrical conductivity. The hydrogel strain sensor can be used for real-time monitoring of various joint movements of the human body, including finger, wrist, elbow, and knee.

To validate this, the colored BaMgSiO4 is synthesized by adding different colorants (Co, Cr, Nd, etc.), displaying both bright chemical color and high photochromic efficiency with fast response speed to sunlight. Upon UV or sunlight irradiation, the photochromic coloration (PC) can effectively composite with CC, then achieving reversible multicolor chromism (deep blue to gray black @Co, dark green to reddish brown @Cr, pale purple to deep purple @Nd, etc.) and precise regulation of light response. The designed photochromic components exhibit on‐demand information display and UV detection, showing great potential in photochromic ceramic backplate and UV dosimetry.

However, achieving precise control over blend morphology remains a significant challenge due to the difficulty of simultaneously controlling the thermodynamic and kinetic parameters that govern morphology formation. In this study, a series of new small-molecule acceptors (SMAs) employing a dual side chain functionalization strategy is designed that incorporates trifluoromethyl (CF3) and phenyl (Ph) groups: SMA-CH3, SMA-CF3 (with CF3 group), and SMA-Ph-CF3 (with both CF3 and phenyl groups). This approach successfully enables delicate tuning of the blend morphology and the development of high-performance OSCs (PCE = 18.5%). CF3 functionalization enhances the thermodynamic compatibility of SMAs with the hydrophobic D18 polymer donor, promoting the formation of intermixed donor/acceptor domains and efficient charge generation. Meanwhile, phenyl functionalization improves SMA aggregation and crystallinity, facilitating strong interconnected SMA assembly and efficient charge transport. As a result, binary OSCs based on D18:SMA-Ph-CF3 achieve a significantly higher PCE of 18.5%, compared to 14.3% for D18:SMA-CH3 and 16.5% for D18:SMA-CF3 OSCs.

However, as the EMG device scales down in dimension, the undesirable interaction between magnets and insufficient area severely limits the performance of the MFC. Here, a high‐performance millimeter scale electromagnetic generator (mmEMG) is devised by the MFC films on both ends of coils inducing highly concentrated magnetic flux. The effect of the MFC is investigated depending on various structural parameters by simulation, and confirmed experimentally. Also, the influence of magnetic properties on the MFC by characterization with different soft magnetic materials is studied. With this process, the mmEMG is optimized with the MFC device showing 4 mWcm−3 despite its light weight and tiny size, a 5.6‐fold improvement in terms of electrical output.
