Premature perovskite films rapidly form at the FAI/PbI 2 interface, inhibiting further reactions between FAI and PbI 2 during the fabrication of perovskite films via the evaporating-spraying hybrid method according to our previous research. In this research, triphenylphosphine oxide (TPPO) was proved to be an effective coordinator that reduces the reaction rate between FAI and PbI 2 at the initial stage, which can be attributed to the hydrogen (H) bonds between FA + and TPPO, and coordinate bonds between TPPO and PbI 2 . Additionally, the quality of perovskite films improved significantly: the trap state density decreased from 1.6 × 10 18 to 3.17 × 10 17 cm −3 , while the crystal size increased from 740 to 940 nm. The champion perovskite device achieved a remarkable efficiency of 20.93% (0.09 cm 2 ) and 16.75% (63.7 cm 2 ), marking one of the highest reported results for the evaporating-spraying hybrid method. Moreover, the perovskite solar cells retained over 80% of their initial performances after 600 h of storage at 60 °C in a nitrogen environment without encapsulation. It also maintained approximately 90% of its initial performance after continuous illumination at 25 °C for 1400 h under the same conditions.

The recently emerged chloride solid electrolytes have garnered significant attention due to their superior ionic conductivity, wide electrochemical stability window, and exceptional compatibility with high-voltage oxide cathodes. Nevertheless, the currently cost-effective Zr-based chloride solid electrolytes face significant challenges, including low ionic conductivity and poor moisture stability. Herein, a versatile Zn2+-doped Zr-based chloride electrolyte is presented, designed to meet the aforementioned requirements. The optimized Li2.4Zr0.8Zn0.2Cl6 exhibits an improved ionic conductivity of 1.13 mS cm−1 at 30 °C. Simultaneously, the Li2.4Zr0.8Zn0.2Cl6 also demonstrates impressive moisture stability, maintaining its structural integrity after exposure to humid air. The mechanism underlying the enhanced moisture stability of Li2.4Zr0.8Zn0.2Cl6 is further elucidated by density functional theory calculations. Most notably, whether coupled with LiCoO2 or LiNi0.8Mn0.1Co0.1O2 cathodes, Li2.4Zr0.8Zn0.2Cl6-based all-solid-state batteries demonstrate exceptional cycling stability and rate performance. This high ionic conduction and moisture-resistant chloride electrolyte holds great promise for significantly advancing the commercialization of all-solid-state lithium batteries. © 2025 Wiley-VCH GmbH.

Chronic wounds have emerged as a formidable challenge in diabetes management, leading to high morbidity and mortality. The diabetic wound healing is often impaired due to recurrent bacterial infections, excessive reactive oxygen species (ROS), and severe hypoxia. Thus, we developed a multifunctional nanoplatform that exhibited remarkable antibacterial activity, ROS scavenging and oxygen-carrying properties. Metal-phenol network (MPN) as core material was synthesized by assembling tannic acid (TA) with Fe2⁺ via coordination and hydrophobic interactions. Subsequently, hemoglobin (Hb) was decorated onto MPN surface through cation-π interactions. MPN protected Hb against oxidation and preserved its physiological function, facilitating oxygen transport. Moreover, MPN-Hb displayed robust and broad-spectrum antioxidant activity that can effectively scavenge ROS and reactive nitrogen species. Under near-infrared (NIR) irradiation, MPN-Hb demonstrated excellent bactericidal activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), effectively eradicated biofilms through hyperthermia. In vivo studies have shown that MPN-Hb with good biocompatibility could effectively eliminate bacteria at the wound site, mitigate the inflammatory response, and promote collagen deposition and angiogenesis, thereby accelerating wound healing. Overall, this multifunctional nanoplatform offers a straightforward, safe, and efficient therapeutic strategy for treating chronic diabetic wounds. © 2025 Elsevier B.V.

Ab-initio insight into electrochemical characteristic of Zr2N monolayer as sodium ion battery by O and Se functional group strategy

As a novel type of two-dimensional electrode material, MXene with versatile surface functional groups can provide additional active sites, exhibiting high pseudo capacitance and large specific capacity. This article uses first principles to investigate the electrochemical properties of oxygen and halogen elements modified Zr2N as anode materials for sodium ion batteries. The results indicate that O and Se functionalized Zr2N material is more suitable as an anode material for sodium ion batteries compared to other functionalized materials. Zr2NT2 (Zr2NO2 and Zr2NSe2) have low diffusion barriers to facilitate the diffusion of sodium ions, with a theoretical capacity of 293.29 mAh/g and 151.29 mAh/g, respectively. The open circuit voltage is in the range of 0–1 V, which can prevent the formation of lithium dendrites and ensure the safe operation of the battery. These characteristics are attributed to the redistribution of surface charges for functionalized Zr2N, which results in uniform interaction forces between adsorbed atoms and the matrix, thereby improving the adsorption stability of sodium ions. In summary, this study reveals the energy storage performance mechanism of O and Se functionalized MXene electrode materials at the microscale, laying a solid foundation for subsequent experimental preparation. © 2025 Elsevier B.V.

Maximum Power Point Tracking Using a Multimode Hunter-Prey Optimization Algorithm for Gradually Varying Power in Centralized Thermoelectric Generation System

引用

Energy technology 2025年第0期

作者： Zhu, Wenchao Li, Peng Yang, Wenlong Xie, Changjun Li, Hao Yang, Yang State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan430070 China School of Automation Wuhan University of Technology Wuhan430070 China Wuhan Industrial Technology Institute of Artificial Intelligence and New Energy Vehicles Wuhan430119 China Hubei Key Laboratory of Advanced Technology for Automotive Components Wuhan University of Technology Wuhan430070 China

The unstructured power outputs from thermoelectric generator (TEG) systems have precipitated the advancement of maximum power point tracking (MPPT) methods toward more intelligent solutions. This article concentrates on centralized TEG systems which work during nonuniform distribution of temperature cases and introduce the hunter-prey optimization algorithm with multimode updating (MMUHPO). Existing MPPT methods based on metaheuristic algorithms pay attention to improving tracking speed, efficiency, oscillation, and call frequency. However, in scenarios marked by gradual changes in power characteristics, the precision of MPPT algorithms can lead to frequent oscillatory searches and elevated computational demands. MMUHPO reduces power loss and simplifies algorithm complexity by improving the original mechanism and introducing termination mechanism and multimode update mechanism. Herein, the proposed algorithm is compared with several widely used MPPT algorithms based on metaheuristic algorithms under five different operating conditions. Remarkably, the MMUHPO algorithm demonstrates a substantial enhancement in energy collection efficiency, with the increase in efficiency reaching up to 109.8%. Finally, real-time data simulation experiments corroborate the exceptional tracking performance of the proposed algorithm. © 2025 Wiley-VCH GmbH.

Introduction of the interfacial layer between filler and matrix: An effective approach towards developing high thermal conductive dielectric composite

In the development of high-performance electronic devices, high thermal conductive dielectric composites are crucial. For PTFE-based dielectric composites, enhancing thermal conductivity while maintaining low dielectric properties remains a challenge. The key issue lies in the high interfacial thermal resistance between fillers and the PTFE matrix, which restricts the improvement of thermal conductivity. This paper focuses on introducing an interfacial layer between the filler and the matrix as an effective approach. By constructing a SiO2 interfacial layer between hBN and PTFE, we formed hBN@SiO2 core-shell structured fillers and then prepared hBN@SiO2/PTFE composites. This method significantly reduces the interfacial thermal resistance. Consequently, the thermal conductivity of the composite reaches 1.40 W/(m·K), the coefficient of thermal expansion decreases, and it still keeps a low dielectric constant of 3.9 and low dielectric loss of 1 × 10−4. This study provides an innovative and effective way for the development of high thermal conductive dielectric composites, which is of great significance for high-power and high-frequency applications. © 2025 Elsevier Ltd and Techna Group S.r.l.
