However, voids and defects arising during fabrication often limit the performance and versatility. An effective electrostatic repulsion-induced alignment strategy is suggested here to overcome the major obstacles in the industrial application of MXene films. This approach combines polydopamine (PDA)-modified MXene with two-dimensional (2D) tantalum disulfide (TaS2) nanosheets to enhance the alignment and compactness of MXene layers. Incorporating a small amount of TaS2 nanosheets, which carry negative charges, facilitates the alignment of PDA-modified MXene sheets during film assembly via electrostatic repulsion. This results in the fabrication of strong and well-ordered composite films with a synergistic effect between MXene and TaS2. The resultant MXene/TaS2 (MXT) films exhibit high mechanical strength (92 MPa), toughness (2.49 MJ·m-3), excellent electrical conductivity (7932 S cm-1), electromagnetic interference (EMI), shielding effectiveness (SE) (62 dB), and superior in-plane thermal conductivity (53.19 W·m-1·K-1). In addition, MXT films demonstrate remarkable Joule heating performance and environmental stability.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"24 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195102","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}

We systematically reveal the synergistic regulation mechanism of biaxial pressure (stack pressure and lateral pressure) and intrinsic mechanical properties (Young's modulus and fracture toughness) on the failure behavior. Under zero external pressure, lithium dendrites preferentially fill pre-existing cracks, inducing a localized tensile stress concentration and accumulating tensile strain energy density at the crack tip. The crack evolution drives into three stages: filling, synchronous propagation, and asynchronous propagation, ultimately forming dendrite-free \"dry cracks\" that cause penetration failure. While stack pressure delays cracking initiation, 100 MPa is required for complete suppression. Moreover, an excessively high stack pressure tends to induce short circuits via lithium creep and penetration. In contrast, lateral pressure efficiently dampens the crack-driving force by directionally suppressing tensile strain along the y-axis, achieving complete crack suppression at a mere 15 MPa, demonstrating significant advantages. Fracture toughness analysis confirms that enhancing fracture toughness disrupts the dendrite-crack positive feedback loop. Young's modulus exhibits a nonlinear regulatory effect. SSEs within a high-risk window of 100-120 GPa suffer exacerbated failures due to competing mechanisms: intensified stress concentration versus strain energy accumulation inhibition. A developed pressure-failure coefficient contour map quantifies the synergistic strategy of stack and lateral pressures, enabling concurrent crack suppression and dendrite penetration protection. Furthermore, customized pressure loading strategies are further proposed for SSEs with distinct mechanical properties. This work establishes fundamental insights for developing highly stable solid-state batteries from the dual perspectives of mechanical constraint design and intrinsic material optimization.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"4 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194558","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}

However, the design of a dual-mode or all-in-one sensor for multiple applications, especially fluorimetric or colorimetric detection of pH and in situ visualization of LFPs, is the most important challenge. In this study, three-arm star-shaped block copolymers were synthesized via sequential atom-transfer radical polymerization (ATRP) of methyl methacrylate (MMA) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) using a core-first strategy. The degree of polymerization (DPn) of the poly(methyl methacrylate) (PMMA) block is 17.5, and the DPn of the poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) block is approximately 17; the polydispersity index (Đ) is about 1.19. The self-assembly of the 3-ArmPMMA-b-PDMAEMA sample resulted in different anisotropic morphologies or Janus nanoparticles, such as snowman, dumbbell-like, multilobe, vesicular, and hollow spheres with regular concavities on the surface, and a narrow particle size distribution. The prepared halochromic nanoparticles containing two oxazolidine derivatives (OXOH and OXNM) were used to detect and monitor pH in the wide range of 1-14 by colorimetric and fluorimetric signals. The main advantage of the developed pH sensor is the high colloidal stability of 3-ArmPMMA-b-PDMAEMA nanoparticles in highly acidic (pH < 3) and alkaline (pH > 10) media. In addition, the halochromic nanoparticles were used as a spray for the in situ visualization of LFPs using aggregation-induced emission (AIE) and fluorescence imaging as a fast strategy for forensic investigations at crime scenes, crime science, and medical diagnostics. The visualized LFPs displayed red emission with high intensity and minimum background emission, and three identification levels were successfully achieved. The prepared halochromic nanoparticles can be introduced as a probe for the detection of pH (1-14) and the in situ visualization of LFPs by spraying.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"214 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194964","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}

This study demonstrates an effective strategy to enhance emission efficiency and stability in blue-emitting quasi-two-dimensional (2D) perovskite films by incorporating polyvinylpyrrolidone (PVP) as a Lewis base additive. PVP interacts strongly with A-site cations and Pb atoms, suppressing halide migration, passivating grain boundaries, and annihilating defects. Its ability to modulate stress within the perovskite layer, especially mitigating phase segregation under electrical stress, is particularly notable. As a result, the PVP-treated quasi-2D perovskite thin films exhibited a photoluminescence quantum yield of 32% and enhanced blue emission stability even at elevated temperatures. The blue LED with PVP-treated quasi-2D perovskites exhibited 6.42 times improved emission efficiency compared to the pristine one, demonstrating superior color stability with negligible electroluminescence peak shifts under high operating voltages. These improvements highlight the dual role of PVP in defect passivation and stress modulation, which significantly enhances the operational stability of the devices. While the emission efficiency remains modest, the improved color stability and extended operational lifetime achieved by PVP treatment represent a critical step toward the practical realization of stable perovskite-based blue LEDs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"2 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145203943","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}

Multiemissive material-based optical sensors possess great potential in detecting structurally similar compounds.

Herein, an energy barrier strategy is utilized to achieve full-spectrum tunable multiemissions from a single lanthanide metal-organic framework (MOF). Using Eu/Tb-MOF as a model, another lanthanide ion acting as the \"energy barrier\" is introduced into the Eu/Tb-MOF to regulate the energy transfer process of the ligand.

The universality of the strategy is validated by choosing other blue-emissive ligands and introducing other energy barrier ions. It is demonstrated that as long as the energy levels of the ligand and the barrier ion are appropriate, the tunable multiemissions can be obtained in a single Ln-MOF.

To address this, polymerization-induced phase separation (PIPS) has gained popularity; however, it still suffers from relatively low ionic conductivity due to the increase in IL content, which may result in leakage or ion aggregation. In this work, we demonstrate that controlled irradiation, combined with PIPS, plays a critical role in increasing the IL content of the ionogel for the enhancement of ionic conductivity. By controlling the irradiation, the high IL content ionogel exhibits higher ionic conductivity via increased cross-link density and degree of phase separation, allowing better segregation of ions while also maintaining excellent structural integrity. Notably, the [EMIM][BF4] ionogel fabricated via PIPS exhibits among the highest ionic conductivities reported for [EMIM]-based PIPS ionogels for supercapacitors and sensors under comparable conditions, measuring 5.51 ± 0.31 mS/cm. Furthermore, the practical applicability of the ionogel as a flexible supercapacitor was demonstrated, as the integrated device delivered a high specific capacitance of 103 F/g at a current density of 0.5 A/g along with an energy density of 122 Wh/kg and a power density of 2928 W/kg. The device also exhibited a high capacitance retention (93%) after 30,000 charge-discharge cycles at 1 A/g and was able to maintain stable electrochemical performance even under repeated mechanical deformation. This study demonstrates that irradiation is an effective strategy to further increase the IL content incorporated for higher ionic conductivity and overall better electrochemical performance while maintaining excellent structural integrity under deformation, underscoring its suitability for flexible and wearable devices.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"28 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189276","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}
