However, commercial ECAs typically contain more than 90 wt % Ag fillers, creating an urgent demand for low-Ag-content alternatives that maintain excellent performance. To address this issue, Ag with 3D structures has significant low-content and structural advantages in efficiently constructing 3D conductive networks in the ECAs system. Herein, three types of Ag-based fractal flowers with 3D branched structures (Ag FW-I, Ag FW-II, and Ag FW-III) were successfully synthesized using a novel, facile, and efficient chemical reduction method. The Ag FW-II particles served as the primary conductive framework, while Ag FW-I and Ag FW-III acted as auxiliary fillers, bridging gaps and connecting isolated regions. When the Ag FW-I, Ag FW-II, and Ag FW-III contents were optimized to 17.5, 50, and 12.5 wt %, respectively, the resulting ternary ECAs can deliver the lowest bulk resistivity of 1.15 × 10-4 Ω·cm and a high adhesion strength of 12.88 MPa. These Ag FWs-based ECAs demonstrate the best balance of conductivity and adhesion strength, offering a promising solution for the electronic packaging industry.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"106 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145357928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is an urgent need for therapeutic platforms that not only eliminate residual melanoma cells but also accelerate wound healing. Cuproptosis has emerged as a promising anticancer strategy. However, a significant challenge remains in overcoming the adaptive defenses of cancer cells and sensitizing them to cuproptosis. Herein, we explore a mitochondrial-targeted Ca/Cu dual-ion chaos inducer (Mito-chaos) by integrating a mitochondria-targeted curcumin derivative (MitoCur) into a calcium- and copper-co-doped Prussian blue nanoplatform. Mito-chaos exhibits excellent mitochondrial targeting, multienzyme-mimicking catalytic activity, and strong NIR-II photothermal properties. Mito-chaos can precisely deliver Cu2+ and Ca2+ ions into mitochondria, disrupting mitochondrial ion homeostasis, inducing calcium overload, and consequently amplifying cuproptosis. Combined with mild NIR-II photothermal treatment, Mito-chaos achieves effective melanoma suppression accompanied by robust antitumor immune activation. Beyond tumor eradication, Mito-chaos significantly enhances skin vascularization and collagen deposition, accelerating postoperative wound healing and reducing wound closure time. This mitochondria-targeted therapeutic platform not only effectively eliminates residual melanoma cells but also promotes tissue regeneration, providing an integrated and effective strategy for melanoma postoperative management. Our study presents a promising paradigm for precisely amplifying subcellular organelle dysfunction to boost cancer cuproptosis therapy and tissue repair.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"19 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145357931","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}

Photopolymerization technology provides a new route for the preparation of SPEs with its advantages of fast, controllable, and low energy consumption. In this paper, the research progress of photopolymerization technology in SPEs is systematically reviewed, and its preparation methods, structural design, optimization strategies, and applications in energy storage equipment, such as lithium metal batteries, sodium metal batteries, and zinc ion batteries are discussed. By optimizing the selection of light source, monomer design, the introduction of photoinitiator and filler, the ionic conductivity, mechanical strength, and interface stability of photopolymerized SPEs were significantly improved. Furthermore, the in situ polymerization strategy effectively reduces the interface impedance and promotes large-scale production. However, photopolymerized SPEs still face challenges such as unclear ion transport mechanisms and insufficient long-term cyclic stability.

Herein, we introduced a trace amount of MgI2 as a dual-functional Janus additive that simultaneously addresses limited capacity and interfacial stability in PEO electrolytes. The Mg2+ competitively coordinates with both PEO chains and TFSI- anions, effectively weakening the Li+-TFSI- interaction and promoting Li+ dissociation, thereby increasing the free Li+ concentration and enhancing interfacial lithium-ion transport. Simultaneously, iodine species (I-/I3-) participate in cathode redox reactions to enhance reversible capacity while facilitating the formation of a robust, inorganic-rich solid electrolyte interphase (SEI) at the anode, which effectively suppresses dendrite formation. As a result, the modified electrolyte delivers a recorded critical current density of 1.7 mA/cm2, and Li||Li symmetric cells achieve ultralong cycling stability for over 10,000 h at 60 °C. A Li||LiFePO4 full battery exhibits exceptional durability of 10 times that of the blank system, with 93.28% capacity retention at 1 C after 2000 cycles.

In this study, N-doped carbon (NC) with large pore size, excellent dispersion, and rich defects are synthesized by the functional group self-assembly technique and is applied as an additive for ACL, which not only increases the pore volume and improves water management to avoid the flooding issues, but also enhances the conductivity of ACL.

The PPD of the optimized MEA increased by 25.7%, from 1.36 to 1.71 W cm-2, and the durability under 0.2 A cm-2 is extended from 280 to 1000 h, with a voltage decay rate of only 186.6 µV h-1.

Strong mixing between pnictogen s- and chalcogen p-orbitals generates active lone pairs, which enhance lattice anharmonicity and lead to ultralow κL. In this study, we leverage machine learning interatomic potential to systematically probe bonding-driven mechanisms and their influence on thermal transport in noncentrosymmetric pnictogen chalcogens. We show that the combined effects of SCALPs, Pn-Pn bonding, and edge-sharing polyhedra enable the formation of antibonding states near the valence band maxima, intensifying phonon scattering. To quantify the underlying anharmonicity, we introduce a set of bonding descriptors─lone pair angle, lone pair distance, ionicity, and hybridization─that capture the influence of local structural motifs and antibonding features near the valence band edge. This bonding-centric framework not only elucidates the origins of ultralow κL but also offers a rational design strategy for accelerating the discovery of high-performance thermoelectric materials.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"150 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145357990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigate how photon interaction frequency, defined as the average time between photon interactions in a single plasmonic hotspot, impacts the plasmon-driven reduction of methyl viologen. We found that simply increasing the photon interaction frequency did not proportionally increase the reduction yield. Instead, photon interaction frequency combined with modulated illumination impacts the charge transfer yield. For continuous wave illumination with periodic illumination, the charge transfer yield was negligible. Conversely, pulsed excitation with intermittent dark periods led to high reaction efficiencies, likely by suppressing competing processes, such as electron-hole annihilation.
