TENGs offer promise for real-time dynamic monitoring, but they are often complicated to manufacture, have low sensitivity, and are easily disturbed by ambient humidity. Herein, a fabric-based integrated triboelectric nanogenerator (F-TENG) is developed, employing waterborne polyurethane (WPU) as both a water-resistant encapsulation and friction layer, and polypyrrole (PPy) as a friction and conductive layer. This design simplifies the fabrication process while simultaneously improving the device's resistance to environmental factors. The micro-filament structure enables localized contact-separation during deformation, initiating the triboelectric effect, while the 3D architecture amplifies local strain, further enhancing sensitivity to weak signals. F-TENG demonstrates effective voltage output during carotid and respiratory monitoring, highlighting its capability to detect subtle physiological signals. Furthermore, F-TENG maintains stable performance under humid conditions, retaining 78.78% of its output voltage as relative humidity increased from 20% to 80%. When implants in the moist environment of a rat's leg, F-TENG exhibits a notable output of 21 V. In addition, the inherent antibacterial properties of F-TENG further enhance its application potential.

Here, a stable atomically dispersed Pd sub-metallene (Pd ADSM) layer supported on the 2D MXene (Mo2TiC2) is reported, which combines the advantages of 2D structures, single atoms, and metal bonds. Pd ADSM shows covalent structures along the z-coordination and highly coordinated metal bonds in the 2D direction. During the alkaline hydrogen evolution reaction (HER), Pd ADSM shows 7- and 112-times higher mass activity than the SAC (Pd SAC) and commercial Pt/C at the overpotential of −108 mV, respectively. Operando characterizations and theoretical calculations reveal that the Pd─Pd interface not only makes the adsorbed water form a flexible hydrogen-bonded skeleton closer to the catalytic center but also reduces the energy barrier for the HER rate-determining step. Moreover, the moderate adsorption energy of Pd─Pd bonds in ADSM can rapidly activate, dissociate, and desorb hydrogen molecules at room temperature, resulting in record-high hydrogen sensing performances (Response time, Recovery time, and Sensitivity for 100 ppm H2 are 4.8, 1.6 s, and 43.5%, respectively).","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"1 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910921","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, structural degradation and elemental dissolution during operation pose significant challenges to achieving long-term stability. Herein, the development of multi-grained NiPt nanocatalysts featuring an atomically ordered Ni3Pt5 phase within intragrain is reported. Ultrasound-assisted synthesis facilitates atomic transposition by supplying sufficient diffusion energy along grain boundaries, enabling unprecedented phase formation. The Ni3Pt5 embedded nanocatalysts exhibit outstanding proton exchange membrane fuel cell performance under both light-duty and heavy-duty vehicle conditions, with significantly reduced Ni dissolution. Under light-duty vehicle conditions, the catalyst achieves a mass activity of 0.94 A mgPt−1 and a 421 mA cm−2 current density (@ 0.8 V in air), retaining 78% of its initial mass activity after long-term operation. Under heavy-duty vehicle conditions, the multi-grained nanocrystal demonstrates only an 8% decrease in Pt utilization, a 5% power loss, and a 13 mV voltage drop, surpassing U.S. Department of Energy (DOE) durability targets. This study underscores the critical role of the atomically ordered Ni3Pt5 phase in stabilizing multi-grained NiPt nanocrystals, enhancing both durability and catalytic activity.

To address these challenges, this work proposes an efficient strategy by introducing single atoms (SAs) into sulfur‐functionalized MXenes (S‐MXenes) catalysts and evaluate their potential in Li‐S batteries through first‐principles calculations. Using high‐throughput screening of various SA‐modified S‐MXenes, this work identifies 73 promising candidates that exhibit exceptional thermodynamic and kinetic stability, along with the effective immobilization of polysulfides. Notably, the incorporation of Ni, Cu, or Zn as SAs into S‐MXenes results in a significant Gibbs free energy barrier reduction by 51%–75%, outperforming graphene‐based catalysts. This reduction arises from SA‐induced surface electron density that influences the adsorption energies of intermediates and thereby disrupts the scaling relations between Li₂S₂ and other key intermediates. Further enhancement in catalytic performance is achieved through strain engineering by shifting the d‐band center of metal atoms to higher energy levels, increasing the chemical affinity for intermediates. To elucidate the intrinsic adsorption properties of intermediates, this work develops a machine learning model with high accuracy (R2 = 0.88), which underscores the pivotal roles of SA electronegativity and local coordination environment in determining adsorption strength, offering valuable insights for the rational design of catalysts.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"37 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910396","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}

A key mechanism in neural regulation of brain cancer involves the activity-dependent cleavage and release of the synaptic adhesion molecule neuroligin-3 (NLGN3). Here, this report describes the preparation of optogenetics-like liposome Lip-CuRA, which is used to regulate the content of NLGN3 in neurons and mediate phototherapy in cancer cells. Lip-CuRA contains upconversion nanoparticles encapsulating CuS (CuS@PUCNPs), a visible light-activated neurotransmitter prodrug RuBi-GABA, and a disintegrin and metalloproteinase (ADAM10) inhibitors GI254023X. Upon 980 nm laser irradiation, the photothermal conversion of CuS not only induces tumor cell apoptosis, but also destroys liposome structure, releasing Rubi-GABA and GI254023X. The UCNPs convert the 980 nm laser into 540 nm, activating RuBi-GABA into GABA. GABA selectively opens Cl⁻ channels in nerve cells, reducing the expression of NLGN3 and the degree of axonal connections. GI254023X inhibits the activity of the ADAM10 enzyme on the nerve surface, reducing the release of NLGN3, thereby blocking the transmission of proliferation and stemness signals. In the GL261-luc orthotopic glioma model, C6-luc orthotopic glioma model, and glioma patient-derived xenograft (PDX) model, Lip-CuRA effectively inhibits tumor recurrence, reduces glioma stemness, and extends survival through a synergistic photothermal and NLGN3-regulating therapy.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"29 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910648","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}
