To tackle this issue, dimethylammonium iodide (DMAI) is frequently included to form black phase DMA_xCs_1-xPbI₃ to accommodate the tolerance factor, however, its phase behavior and effect on device stability are still not well understood. In this work, we employed transient reflection spectroscopy with front and back laser excitation to investigate the phase transformation kinetics and the vertical phase distribution of DMA_xCs_1-xPbI₃ films during thermal annealing. Our results indicate that these properties are influenced by the choice of substrate. During prolonged annealing, DMAI partially evaporates, causing lattice reorganization and leading to surface degradation. For substrates with a strong clamping effect, the surface DMA_xCs_1-xPbI₃ transitions to a black phase CsPbI₃, whereas for those with a weak clamping effect, it degrades directly to the yellow phase. Importantly, films of DMA_xCs_1-xPbI₃ exhibit improved stability when annealed close to the boundary where the black CsPbI₃ phase emerges at the surface, particularly when supported by an organic substrate that has a suitable thermal expansion coefficient and strong coordination with perovskite.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"50 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184011","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}

Interestingly, the electrical stimulation is able to affect the optical excitatory post-synaptic current (EPSC), which is attributed to the PVP directional polarization effect.

Subsequently, the ammonium salt of fucoidan was employed for the multifunctional regulation of SnO₂ nanocrystals, inhibiting agglomeration and improving the quality of the formed films. Consequently, the interface wettability and strain release showed significant improvement, and the vertical growth of the perovskite nanocrystals was enhanced.

Organic solar cells (OSCs) based on the acceptor-poor active layer well satisfy the two demands. Unfortunately, the reduced acceptor content inevitably suppresses the photovoltaic performance by cutting off the electron transporting pathway. To alleviate the performance decay at this situation, a three-aspect strategy is proposed. First, polymer acceptors are used instead of small molecule acceptors to provide continuous channels for electron transport. Second, more extended chain conformation is introduced. Third, enhance acceptor crystallinity with proper domain purity to decrease the charge recombination. Obeying these rules, the steep power conversion efficiency (PCE) decay appears at a smaller donor:acceptor (D:A) ratio. Comparing at the same ratio of 1:0.4, the optimized all-polymer OSC has a PCE of 15.13% which largely outperforms that of 11.23% in the polymer-small molecule counterpart.

Our MXene-based Triboelectric Nanogenerator Resonance Force-Sensing System (MXTENG-RFS) harnesses the sensed force to power itself, enabling long-term operation in remote environments. This system also employs resonant frequency shifts—immune to environmental factors, to effectively convey sensed information. Supported by an innovative frequency and amplitude boosting approach, the MXTENG-RFS achieves active-electronic-free wireless data transmission while maintaining minimal power consumption and electromagnetic emissions. The device is maintenance-free and stealth-compatible. Through precise nanomaterial engineering, we have achieved high power density, robust sensing performance, and long-term environmental stability. Furthermore, pioneering 3D-multi-nanomaterial printing protocols have been developed to enable scalability, large-scale production, rapid prototyping, low cost, design freedom, and high resolution for the MXTENG-RFS devices. As a proof of concept, we demonstrated a wearable e-skin for augmented interactive human–drone operation—providing battery-free, self-powered, and wireless drone control—ideal for reconnaissance and surveillance in remote environments. By enabling self-powered operation, electronic-free and direct, transmission, passive design, wireless functionality, robustness, a miniaturized form, low cost, and user-friendliness, we envision our MXTENG-RFS system as a maintenance-free sensing and communication solution ideally suited for resource-limited environments, space missions, and critical remote areas.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"98 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144177128","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}

In this work, inspired by animal fur, we propose a triboelectric tactile sensing array in order to achieve sensitive awareness of gentle palm interactions. Which is of great significance for enhancing the functionality of companion and pet robots. The tactile sensor consists of a cluster of single-electrode structured triboelectric sensing units based on PTFE film coated conductive yarns. The dynamic signals of the tactile sensing array can accurately perceive 3D-depth interaction information of touch such as direction, speed and gesture. It allows for more comprehensive and accurate pattern recognition in human-machine interaction scenarios. Furthermore, a deep learning model is used to assist the recognition of complex signals from the tactile sensing array under various interactions. Among a dataset of 17 palmar interactions, a recognition accuracy up to 96.8% was achieved. As a demonstration, we finally construct an intelligent human-machine interface based on this tactile sensing array. It is integrated onto a shape-shifting robot working as a piece of fur of an intelligent pet robot.
