However, existing UV dosimetry technologies face challenges in balancing cost, portability, accuracy, and power efficiency. To address these challenges, a UV-programmed non-volatile memory device is developed based on polyvinylpyrrolidone (PVP)-functionalized carbon nanotube (CNT) network films. This memory device functions as a dosimeter utilizing UV-induced bond scission in PVP and the subsequent chemisorption of the resulting radicals to modulate CNT network conductance, exhibiting precise cumulative UV dose tracking ability with a high resolution of 36 µJ cm−2. The cumulative UVC dose can be directly read using a low-cost circuit based on the linear relationship between conductance and UV dose. With a high dynamic range of 90 mJ cm−2, the device is sufficient for monitoring typical UV exposure within a few days, ensuring practical usability. Additionally, it demonstrates excellent reproducibility, stability under mechanical deformation, and a scalable, solution-processable fabrication process at a cost of ≈1 cent per unit. By integrating sensing and memory functionality into a disposable, ultra-low-cost platform, this personal UV dosimeter offers an accessible solution for health and occupational safety monitoring in resource-limited areas as frugal innovation.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"181 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320245","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, precise control of AF order and spin transport properties, and understanding of their physical mechanisms, remains challenging. In this work, the interplay between crystal structure, magnetic orders, and anomalous Hall effect (AHE) is established in single-crystalline Mn₃Pt (001) synthesized from a [Mn/Pt]20 multilayers with tunable Mn layer thickness (tMn). Resonant elastic X-ray scattering reveals a magnetic order transition at Tc≈240 K for the sample with tMn = 0.7 nm, which notably coincides with an AHE polarity reversal at ≈230 K. Importantly, we demonstrate that Tc can be precisely engineered by fine-tuning tMn to modulate lattice constant and spin canting. Further, first-principles calculations affirm the lattice parameter and spin canting dependence of AHE from the ground-state Γ10 magnetic symmetry. Finally, a refined analytical model is introduced to elucidate the intrinsic and extrinsic AHE contributions in NCAF material comprising hybrid magnetic orders. These findings provide a robust framework for tailoring transport properties toward the realization of next-generation AF computing technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"600 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320246","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}

For underwater acoustic communication, the GI shows unique advantages in high‐fidelity and secure transfer of information despite the random and time‐varying noises everywhere in water. However, GI has severe limitation in information transmission rates due to the gigantic volume of sampling. Here the parallel GI is proposed to implement anti‐interference and high‐speed underwater acoustic communication. To minimize the local disturbance of acoustic fields and improve measurement accuracy, a chip‐scale sensor with the size of 5 × 5 mm2 and the thickness of ≈600 µm is fabricated. At the frequency of 7 kHz, the device sensitivity can reach ‐140 dB re 1 rad/µPa. In parallel GI, one signal sequence that carries three‐channel information is first launched via the speckle multiplexing technology, all of which can then be well decoded at the receiving end through the GI algorithm.

Key obstacles in treatment include elevated intracellular glutathione (GSH), poor drug penetration, and an immunosuppressive tumor microenvironment. Herein, a four-in-one Janus-type near-infrared (NIR)-driven nanomotor is employed, composed of copper selenide (Cu2-xSe) asymmetrically coated with disulfide-bridged periodic mesoporous organosilica (PMO) and loaded with doxorubicin (DOX), termed C&P-DOX. Upon NIR irradiation, Cu2-xSe generates localized hyperthermia, propelling the nanomotor into deep tumor regions due to their asymmetrical structure. After internalization, high GSH triggers disulfide cleavage, promoting GSH depletion, disrupting redox homeostasis, and achieving controlled DOX release. The uniform distribution and effective release of DOX throughout the tumor enhance cytotoxic effects, inducing significant tumor cell apoptosis. In addition, the synergistic mild photothermal therapy and chemotherapy induce immunogenic cell death, releasing damage-associated molecular patterns and tumor-associated antigens that promote dendritic cell maturation and T-cell activation. This process transforms the tumor immunosuppressive microenvironment into an immunogenic environment, enhancing cytotoxic T lymphocyte infiltration and synergizing with PD-L1 antibody therapy to amplify immune responses. The four-pronged C&P-DOX nanomotor effectively penetrates deep tumors, depletes GSH, combines tumor treatment, and enhances immunotherapy outcomes, integrating active synergistic chemo-photothermal-immune therapy for improved TNBC treatment.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"145 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320239","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, a hybrid polymer coated separator with high Young's modulus and ion conductivity is designed by integrating proton-doped polyaniline (PANi) nanosheets with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP). Density functional theory (DFT) calculation confirms that the proton-doped PANi nanosheets interact with TFSI− anions and its 2D confinement effect induces conformational transition of PVDF to the polar β phase. These synergistic effects optimize Li+ transport. Besides, finite element simulations and in situ optical microscopy indicate that the conjugated structure of PANi promotes electron delocalization and homogenizes the potential across lithium anode surface, guiding a uniform Li+ flux and dense lithium deposition. Moreover, the hybrid polymer coating leads to the formation of LiF-enriched SEI on lithium metal surfaces. As a result, Li||Li symmetric batteries with the hybrid polymer coated separator exhibit stable cycling for over 2000 h at a current density of 10 mA cm⁻2.

Herein, it is demonstrated the dual-mode switching of photodetection and neuromorphic photoelectric memory in a VS-ReS2/WSe2 heterostructure. The sulfur vacancies (VS) in ReS2 induced by strong light irradiation together with the electric field can synergistically modulate the carrier transport in the heterostructure device. As result, under negative bias voltage, the device exhibits a photodetection function with ultrafast response speed (τrise = 6.63 µs, τdecay = 6.28 µs) and strong polarization-dependence (anisotropy ratio: 4.0), which enables the device novel photoelectric logic outputs of “AND” and “OR” as well as high-resolution image sensing. Under positive bias voltage, the device exhibits a photoelectric memory function with fast optical writing and electrical erasing operations. The memory device can control and stabilize more than 128 operating states (7-bit), and it displays an over 10 years retention time.

Herein, a strategy for synthesizing hydrogels with highly thermally conductive MXene flakes is introduced enabling dual functions of autonomous moisture harvesting and cyclic transpiration cooling. A lithium bromide–polyacrylamide/MXene (Li-PAAm/MXene) hydrogel is engineered by integrating MXene into polyacrylamide (PAAm) chains via hydrogen bonding, simultaneously enhancing thermal conductivity through microscale thermal bridges and increasing hygroscopic capacity through synergistic effect of MXene and lithium bromide (LiBr), thereby generating more moisture sorption sites and lowering diffusion energy barriers. Morphology, chemical, and thermal characterizations demonstrate the formation of heat-transfer microchannels within the hydrogel, resulting in higher thermal conductivity and enhanced water evaporation. Hygroscopic capacity tests and molecular dynamics simulations further reveal that the synergy between MXene and LiBr increases osmotic pressure and water diffusion rates, leading to more efficient moisture sorption. This highly thermally conductive hygroscopic hydrogel demonstrates efficient cyclic transpiration cooling, outperforming commercial heat dissipation films and conventional hygroscopic hydrogels, making it a promising candidate for advanced thermal management in electronics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"44 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320249","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 new strategy is reported to resolve the intrinsic contradictions between high sodiophobicity and interfacial contacts with a “kinetic-driven alloy sinking” process. Specifically, the sodiophilic and electronic conductive alloy (e.g., KNa2) is spontaneously “sunk” into bulk Na metal, thus remaining a sodiophobic/ionic conductive but intimately contacted interface (e.g., NaF). Unlike conventional concept of sodiophilic interface, this work demonstrates the advantage of sodiophobic modification with an in situ formed ionic conductive interphase, which establishes a foundational distinction from prior literatures. Consequently, an ultrahigh time-constant mode critical current density (CCD) of 4.0 mA cm−2 is achieved, surpassing the state-of-the-art values in existing literature. The fundamental understanding on interfacial sodiophobicity and conduction types of interphases will provide new insight for designing high-performance SSSBs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"233 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312181","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}
