To overcome the unstable shortage of reported triboelectric yarn with a single electrode and two freestanding electrodes, this work designed a coaxially braided triboelectric-sensing thread (CBTT) with a braided mesh spacer separating two-electrodes, which potentially meets the daily and long-term stable monitoring of human respiratory movements, and the effects of the braiding parameters of the mesh spacer on the performance of the CBTT were discussed. The results show that both the braiding process parameters of the mesh spacer and the specification of the mesh-braiding yarn affect the performance of the prepared CBTT. Among them, CBTT prepared by nylon monofilaments with a diameter of 0.2 mm and a 30° on-machine braiding angle had the best sensing performance under the designed strain range. In addition, for the respiratory state monitoring, the output response and the accuracy of CBTT with a mesh spacer are highest among three kinds of the studied sensing yarns with coaxially braiding structure. These results indicated the stable structure advantage of the seamless integration of a mesh spacer into the coaxially braiding two-electrodes triboelectric sensing yarn and brings new tools for user-friendly health monitoring.</p>","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"20013-20021"},"PeriodicalIF":8.3,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661594","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}

Cu is a representative catalyst with high eCO₂R activity.

The nanoconfined environment facilitated the selective growth of pure CsPbBr₃ phases, avoiding unwanted Cs₄PbBr₆ formation. The resulting nanoconfined PQDs, CsPbBr₃@MSN, exhibited tunable emission from blue to green (470 to 515 nm), a high quantum yield (36.8%), and enhanced stability. Moreover, the PQD composites demonstrated exceptional performance in detecting the pesticide dicloran, achieving a detection limit of 0.16 μM, far below China's national standard requirement (34.0 μM). The detection mechanism involved competitive adsorption and phase transitions from the cubic CsPbBr₃ phase to the quasi-2D CsPb₂Br₅ phase.

While layered double hydroxide (LDH)-supported Pt catalysts exhibit complementary advantages and exceptional performance in overall water splitting (OWS), the absence of a robust coordination structure between Pt and LDH constrains their activity and stability. Herein, we report a coordination engineering strategy to alter the coordination structure of Pt on the surface of NiFe LDH using atomic layer deposition (ALD) for OWS. The synthesized Pt/NiFe LDH-O catalyst, featuring the 2-coordinate Pt-OH and 6-coordinate Pt-Pt, exhibits a η₁₀ = 14 mV for hydrogen evolution reaction (HER), a η₁₀₀ = 287 mV for oxygen evolution reaction (OER), and an effective OWS activity (η₁₀ = 1.496 V) for over 200 h. Combining structural and electrochemical characterizations, we confirmed that the coordination engineering affected the nucleation and growth of Pt on NiFe LDH, leading to a decrease of Pt-OH coordination and an increase of Pt-Pt coordination, thereby enhancing the hydrolysis capability of Pt and shifting the rate-determining step (RDS) from the Volmer step to the Heyrovsky step, which contributed to the excellent OWS performance. The density functional theory (DFT) results demonstrated that the electronic structure of NiFe LDH is considerably regulated by an increase in Pt-Pt coordination, facilitating charge redistribution.

Crafting of Au nanostars using BBCPs is rendered by bridging the latter with Au³⁺ ions as cross-linkers that have multiple coordination sites.
