In this work, we explored the structure-performance relationships of various RuO₂ electrocatalysts using a combination of techniques. Cyclic voltammetry revealed that the redox behavior and adsorption energies of key intermediates (*OH and *O) differ based on the crystallinity and particle size of RuO₂. Hydrogen peroxide (H₂O₂) as a probing molecule indicated that the interaction strength of the *OOH intermediate is stronger on amorphous and low-crystallinity RuO₂ than on highly crystalline RuO₂. Furthermore, in-situ techniques, including electrochemical attenuated total reflectance surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS), electrochemical-quartz crystal microbalance (QCM), and Raman spectroscopy, showed that amorphous RuO₂ hydrate exhibited higher OER activity but lower stability, while highly crystalline rutile RuO₂ was more stable up to 1.6 V but had weaker intermediate adsorption. These findings provide a clear understanding of how structural differences impact the catalytic performance and stability of RuO₂ electrocatalysts, offering guidance for optimizing OER catalysts.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"137 ","pages":"Article 110800"},"PeriodicalIF":16.8,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143452185","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}

Two CIMs were easily obtained by readily available raw materials and one-step reaction, exhibiting low product cost and excellent solubility. Results demonstrate that these 2-hydroxyethyl amino functionalized CIMs not only remain many outstanding advantages of bis(2-hydroxyethyl) amino, including reduced work function of Ag electrode, obvious self-doping effect, well-matched molecular energy levels and good contact with metal electrode, but also can improve thermal stability and dipole moment, reduce surface energy, optimize the contact with active layer, and increase electron conductivity and mobility. Benefitting from these comprehensive characteristics, organic solar cells (OSCs) based on PM6:L8-BO with <strong>PDINHOH</strong> as the CIM achieved an outstanding PCE up to 19.25 %, which is obviously higher than that of the counterpart <strong>NDINHOH</strong> (18.60 %) and that with the commonly used CIMs of PFN-Br (17.37 %) and PDINN (18.09 %) as well as the bis(2-hydroxyethyl) amino functionalized analogue. Importantly, these CIMs show good universal application in different active layer systems, metal electrodes and device structures. Additionally, <strong>PDINHOH</strong>-modified devices exhibit excellent storage stability, thermal and photo stability.

However, existing devices still have limitations regarding energy supply, sensitivity, structural flexibility, fabrication cost, and system integration. Here, we proposed a wearable fountain-inspired triboelectric nanogenerator (FI-TENG) assisted by machine learning. The continuous sliding fountain-inspired structure can realize the effective amplification of the triboelectric layer displacement and positive pressure, and improve the shortcomings of the traditional TENG structure, such as poor electrical output performance, narrow sensing range and difficult to effectively sense the negative angle. By optimizing the design of the triangular displacement amplification angle, the tightened gap width, and the thickness of the sliding polyethylene terephthalate (PET) film, the performance of the optimal solution was improved by 70 % compared to the worst solution. The inconsistency between human body motion and TENG displacement direction was solved by introducing a slider-crank mechanism, which smoothly transformed the joint rotational motion into a linear motion of the slider. Due to its unique structural design, FI-TENG could efficiently harvest and accurately sense the positive and negative rotational motions of the human body's rotational joints, rehabilitation beds, and six-axis robots. As an energy application, when FI-TENG was installed in the wrist joint as a test environment, its maximum output power density could reach 64.65 mW/m² (rotation angle, frequency, and load resistance of 60°, 1 Hz, and 80MΩ). Based on the random forest (RF) machine learning method and intelligent microcontroller, an edge-AI intelligent system for human wrist rotation direction recognition was established. Finally, combined with the MobileNetV3-Small lightweight neural network, intelligent recognition based on two-dimensional (2D) images with higher accuracy (average accuracy of 97.56 %) was realized.
