This NMP surface modification on LPSCl improves electrochemical stability of the SE in the positive electrode and stabilizes the lithium-metal interface when used as a separator. When used as SE in positive electrode and separator, the modified LPSCl (m-LPSCl) increases the first cycle discharge capacity by ∼11 mAh g–1 at a current density of 0.21 mA cm–2 and improves capacity retention by 10% over pristine LPSCl (p-LPSCl) after 100 cycles. As a separator, higher critical current density is reached with m-LPSCl (1.6 mA cm–2) than with p-LPSCl (1 mA cm–2) before shorting of the cell. For the pair of single-crystal LiNiO2 (LNO)-positive electrode and lithium metal-negative electrode, m-LPSCl enables over 100 stable cycles, significantly outperforming the cell with p-LPSCl, which shorts after 25 cycles. Overall, this study introduces a scalable method for modifying LPSCl by solvent treatment that improves positive electrode performance and increases stability of the lithium metal-negative electrode interface.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"14 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218683","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 leverages the catechol and amino groups in polydopamine (PDA) molecules to achieve simultaneous loading of Na+ and Cl– ions. Through potassium persulfate oxidation to protonate PDA's amino groups for Cl– adsorption, followed by Tris-base pH adjustment to facilitate Na+ binding with catechol groups, we successfully confined sodium chloride (NaCl) within PDA via layer-by-layer assembly, creating highly efficient NaCl@PDA microwave-responsive nanoparticles. Systematic investigation revealed that toluene and potassium persulfate dosage significantly influenced nanoparticle size, with 2 g of potassium persulfate yielding uniform spherical nanoparticles (≈149 nm diameter) with well-defined morphology. Through systematic optimization of the NaCl content, we found that a loading of 36.0 wt % endowed the nanoparticles with exceptional thermal conversion performance under ultralow-power microwave irradiation (2 W, 2450 MHz), achieving 53 °C within 600 s demonstrating 1.7-fold and 1.4-fold faster heating rates compared to physiological saline and pure PDA nanoparticles, respectively.

The working electrode comprises a poly(vinyl alcohol)/aramid nanofiber (PVA/ANF) hydrogel containing FeMo-N/C and an MXene conductive network. The hydrated microneedle architecture provides tissue-conformal contact and analyte transport, FeMo-N/C enhances the NO-associated electrochemical response, and MXene improves interfacial charge transfer. The resulting platform responds to NO from 1 nM to 100 μM with a detection limit of 0.3 nM and discriminates NO from representative electroactive plant interferents. Chitosan nanoparticles containing S-nitroso-mercaptosuccinic acid were used to moderate NO release, and the microneedle interface resolved treatment-dependent leaf signals over 7 days under salt stress. Signal attenuation by the NO scavenger cPTIO supported the NO-related origin of the electrochemical response. The time-resolved readout was accompanied by improved growth, reduced lipid peroxidation, changes in osmotic and antioxidant responses, and altered expression of stress-responsive genes.

In this work, we use annealing in air to uncover the magnetic phase diagram of Cr2Te3. We correlate magnetic properties with layer stacking and the interlayer distance; both depend strongly on the annealing temperature. In particular, disorder in layer stacking plays a key role in the magnetic properties of Cr2Te3 and more generally of vdW ferromagnets. By annealing at 375 °C, we can eventually raise the Tc of Cr2Te3 up to 303 K in the epitaxial Cr2Te3/WSe2 vdW heterostructure with in-plane magnetic anisotropy.

Nevertheless, the dark current density (Jd) of OPDs exhibits a pronounced increase under applied reverse bias, which consequently degrades the specific detectivity (D*). To tackle this challenge, this work proposes an interface engineering strategy based on Sn/Cl co-doped ZnO (SCZO). The doping effectively reduces oxygen defects in ZnO, causing the valence band maximum (VBM) to shift downward, thereby suppressing hole injection under bias and reducing Jd. Experiments show that the SCZO-based device exhibits a Jd of 4.05 × 10–11 A cm–2 at –0.1 V, nearly one order of magnitude lower than that of the control device (4.07 × 10–10 A cm–2). Notably, the SCZO-based OPD enables real-time and accurate monitoring of human heart rate, demonstrating its considerable potential for health-monitoring applications. Furthermore, OPDs incorporating the SCZO interface exhibit excellent imaging performance under 820 nm illumination. These findings underscore the significant potential of SCZO-based OPDs for flexible, wearable health monitoring and near-infrared imaging applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"10 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221474","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}
