Solvated zinc ions are prone to undergo desolvation at the electrode/electrolyte interfaces, and unstable H2O molecules within the solvated sheaths tend to trigger hydrogen evolution reaction (HER), further accelerating interfaces decay. Herein, we propose for the first time a novel strategy to enhance the interfacial stabilities by in-situ dynamic reconstruction of weakly solvated Zn2+ during the desolvation processes at heterointerfaces. Theoretical calculations indicate that, due to built-in electric field effects (BEFs), the plating/stripping mechanism shifts from [Zn(H2O)6]2+ to [Zn(H2O)5(SO4)2-]2+ without additional electrolyte additives, reducing the solvation ability of H2O, enhancing the competitive coordination of SO42−, essentially eliminating the undesirable side effects of anodes. Hence, symmetric cells can operate stably for 3000 h (51.7-times increase in cycle life), and the full cells can operate stably for 5000 cycles (51.5-times increase in cycle life). This study provides valuable insights into the critical design of weakly solvated Zn2+ and desolvation processes at heterointerfaces.

Ultra-high temperature materials are desirable to withstand the severe aero-thermochemical environments of hypersonic flight, paving the groundworks for flight speeds exceeding Mach 5. Here, we present a novel ultra-high temperature composite with superior ablation resistances up to 3000 °C for 900 s, utilizing a tailored ultra-high melting point HfC0.76N0.24 matrix reinforced with short carbon fibers. The ablation-resistant capability of this composite is over 14 times greater than that of HfC at 3000 °C. Furthermore, this research presents the first comprehensive investigation into the internal mechanisms governing thermal oxidation evolution of HfC0.76N0.24 matrix through a combination of experimental results and theoretical simulations. The mechanistic details of these complex oxidation processes are elucidated in terms of chemical bonding and clusters evolutions, along with their relationship to cooperative oxygen atoms and molecules. Notably, nitrogen atoms do not directly generate gas and escape from the composites, rather, they interact with hafnium atoms to form Hf-C-N-O clusters with robust bonding for enhanced viscosity during ablation. These findings provide valuable insights into the transition from micro to macro scales, which will be the paradigm of inspiring and accelerating materials discovery in this field, as well as taking advantage of their full potential in the application of hypersonic aircraft and spacecraft vehicles.

Despite extensive investigation into various electrocatalysts to enhance the progressive redox transformations of sulfur species in Li-S batteries (LSBs), their catalytic abilities are often hindered by suboptimal adsorption-desorption dynamics and slow charge transfer. Herein, a representative Co0.1Mo0.9P/MXene heterostructure electrocatalyst with optimal p-band centers and interfacial charge redistribution is engineered as a model to expedite bidirectional redox kinetics of sulfur via appropriate Co doping and built-in electric field (BIEF) effect. Theoretical and experimental results corroborate that the optimal Co-doping level and BIEF heterostructure adjusts the p-band center of active phosphorus sites in Co0.1Mo0.9P/MXene to optimize the adsorption properties and catalytic performance of sulfur species, the BIEF between Co0.1Mo0.9P and MXene significantly decreases the activation energy as well as Gibbs free energy of rate-determining step, accelerates interfacial electron/Li+ transfer rate during cycling, thereby accelerating dual-directional sulfur catalytic conversion rate in LSBs. Consequently, the S/Co0.1Mo0.9P/MXene cathode attains a large initial capacity of 1357 mAh g−1 at 0.2 C and a 500-cycle long stability (0.071% decay rate per cycle) at 0.5 C. Impressively, the high-loading S/Co0.1Mo0.9P/MXene cathode (sulfur loading: 5.2 mg cm−2) also presents a remarkable initial areal capacity (6.5 mAh cm−2) with superior cycling stability under lean electrolyte (4.8 μL mgsulfur−1) conditions, and its Li-S pouch cell delivers a high capacity of 1029.4 mAh g−1. This study enhances the comprehension of catalyst effect in Li-S chemistry and provides important guidelines for designing effective dual-directional Li-S catalysts.
尽管对各种电催化剂进行了广泛的研究，以增强锂硫电池（LSBs）中硫的渐进氧化还原转化，但它们的催化能力往往受到次优吸附-解吸动力学和缓慢电荷转移的阻碍。本文设计了具有代表性的Co0.1Mo0.9P/MXene异质结构电催化剂，通过适当的Co掺杂和内置电场（BIEF）效应来加速硫的双向氧化还原动力学，该催化剂具有最佳的p带中心和界面电荷重分布。理论和实验结果证实，最佳共掺杂水平和BIEF异质结构调节了Co0.1Mo0.9P/MXene中活性磷位点的p带中心，优化了硫类的吸附性能和催化性能，Co0.1Mo0.9P与MXene之间的BIEF显著降低了速率决定步骤的活化能和吉布斯自由能，加速了循环过程中界面电子/Li+的转移速率。从而加快了lbs中硫的双向催化转化率。因此，S/Co0.1Mo0.9P/MXene阴极在0.2 C下获得了1357 mAh g−1的大初始容量，在0.5 C下获得了500循环长的稳定性（每周期衰减率为0.071%）。令人印象深刻的是，高负载S/Co0.1Mo0.9P/MXene阴极（硫负载：5.2 mg cm−2）也具有显著的初始面积容量（6.5 mAh cm−2），并且在稀薄电解质（4.8 μL mg硫−1）条件下具有优异的循环稳定性，其Li-S袋电池的容量高达1029.4 mAh g−1。该研究增强了对锂硫化学中催化剂作用的理解，为设计有效的双向锂硫催化剂提供了重要的指导。

Electrochemical nitrogen reduction reaction (ENRR) is emerging as a favorable option to the power-intensive Haber-Bosch process for ammonia synthesis. However, obstacles such as poor selectivity, low production rates, and competition against the hydrogen evolution reaction hinder its practical implementation. To address these, the design of highly active catalysts is critical. Single-atom catalysts (SACs) have shown great potential because of their maximized atom utilization, but their limited stability and low metal loading restrict their performances. On the other hand, dual-atom catalysts (DACs) are atomic catalysts with two metal atoms nearby and offer enhanced electrocatalytic performances by aligning with the N ≡ N bond to enhance N2 reduction efficiency, potentially overcoming the limitations of SAC. This review discusses recent advances in SACs and more importantly DACs for ENRR, highlighting their advantages, limitations, and the need for advanced characterization techniques to better understand catalyst behavior. The review concludes by underscoring the importance of research to optimize these catalysts for efficient and sustainable nitrogen fixation.

Developing advanced secondary batteries with low cost and high safety has attracted increasing research interests across the world. In particular, the aqueous zinc-ion battery (AZIB) has been regarded as a promising candidate owing to the high abundance and capacity of Zn metal. Currently, manganese-based and vanadium-based oxides are most common choices for cathode materials used in AZIBs, but they unfortunately show a moderate cell voltage and limited rate performance induced by slow intercalation-extraction kinetics of Zn2+ ions. To address these issues, alternative cathode systems with tunable redox potentials and intrinsic fast kinetics have been exploited. In the past few years, conversion-type cathodes of I2 and S have become the most illustrative examples to match or even surpass the performance of conventional metal oxide cathodes in AZIBs. Herein, we sum up most recent progress in conversion-type cathodes and focus on novel ideas and concepts in designing/modifying cathodes for AZIBs with high voltage/capacity. Additionally, potential directions and future efforts are tentatively proposed for further development of conversion-type cathodes, aiming to speed up the practical application of AZIBs.

Critical engineering applications, such as landing gears and armor protection, require structural materials withstanding high strength and significant plastic deformation. Nanoprecipitate-strengthened high-entropy alloys (HEAs) are considered as promising candidates for structural applications due to their enhanced strength and exceptional work-hardening capability. Herein, we report a FeCoNiAlTi-type HEA that achieves ultrahigh gigapascal yield strength from quasi-static to dynamic loading conditions and superb resistance to adiabatic shear failure. This is accomplished by introducing high-density coherent L12 nanoprecipitates. Multiscale characterization and molecular dynamics simulation demonstrate that the L12 nanoprecipitates exhibit multiple functions during impact, not only as the dislocation barrier and the dislocation transmission medium, but also as energy-absorbing islands that disperse the stress spikes through order-to-disorder transition, which result in extraordinary impact resistance. These findings shed light on the development of novel impact-resistant metallic materials.

The exceptional electrochemical performance of zinc anodes is frequently impeded by inadequate deposition kinetics and interfacial chemistry. Herein, we introduce the stereoisomerism to inform the balanced selection of electrolyte additives, taking into account their solvation and adsorption properties, to achieve the optimal deposition behaviors and electrochemical performance. The three-point coplanar adsorption configuration, in comparison to two-point adsorption, effectively mitigates the interference of water molecules and establishes a coplanar templating effect. This approach fosters a uniform distribution of charges, encourages the preferential orientation growth of (002) planes for uniform zinc deposition. Moreover, an appropriate level of solvation ability can modulate the solvation structure without substantially increasing the de-solvation energy barrier, thereby facilitating faster deposition kinetics than what is observed in cases of strong solvation. As a result, Zn//Zn cell can achieve an excellent performance of more than 3470 h at 2 mA cm−2 and 1 mAh cm−2, and Zn//AC full cell can work for 50000 cycles at 3 A g−1. Additionally, under practical conditions (N/P=4.37), the assembled Zn//I2 full cell demonstrates stable lifespan for 710 cycles at 1 A g−1. This work showcases the interplay between adsorption configuration of stereoisomeric additives on the cycling.
锌阳极优异的电化学性能经常受到不充分的沉积动力学和界面化学的阻碍。在此，我们引入立体异构来指导电解质添加剂的平衡选择，考虑其溶剂化和吸附性能，以实现最佳的沉积行为和电化学性能。与两点吸附相比，三点共面吸附构型有效地减轻了水分子的干扰，建立了共面模板效应。这种方法促进了电荷的均匀分布，促进了（002）平面的优先取向生长，以实现均匀的锌沉积。此外，适当水平的溶剂化能力可以调节溶剂化结构，而不会大幅增加脱溶剂能垒，从而促进比强溶剂化情况下观察到的更快的沉积动力学。结果表明，Zn//Zn电池在2 mA cm - 2和1 mAh cm - 2下可实现3470 h以上的优异性能，Zn//AC电池在3 a g - 1下可工作50000次。此外，在实际条件下（N/P=4.37），组装的Zn/ I2完整电池在1 A g−1下可以稳定使用710次。这项工作展示了立体异构体添加剂在循环中的吸附构型之间的相互作用。

The efficiency of perovskite solar cells (PSCs) has progressed rapidly, exceeding 26% for single-junction devices and surpassing 34% in perovskite-silicon tandem configurations, establishing PSCs as a promising alternative to traditional photovoltaic technologies. However, their commercialization is constrained by significant stability challenges in outdoor environments. This review critically examines key cell-level issues affecting the long-term performance and reliability of PSCs, focusing on instabilities arising from the intrinsic phases of the perovskite absorber and external stress factors. Mitigation strategies to enhance stability are discussed, alongside recent advancements in charge transport layers, electrodes, and interfaces aimed at reducing environmental degradation and improving energy level alignment for efficient charge extraction. The importance of accelerated aging tests and the establishment of standardized protocols is underscored for accurately predicting device lifetimes and identifying failure mechanisms, thereby ensuring stability under real-world conditions. Furthermore, a comprehensive techno-economic analysis evaluates how advancements in materials and strategic innovations influence efficiency, durability, and cost, which are critical for the commercial adoption of PSCs. This review delineates the essential steps required to transition PSC technology from laboratory-scale research to widespread commercialization within the global photovoltaic industry.

Lithium (Li) metal batteries (LMBs) featuring ultrahigh energy densities are expected as ones of the most prominent devices for future energy storage applications. Nevertheless, the practical application of LMBs is still plagued by the poor interfacial stability of Li metal anode. Inorganic-rich interlayer derived from anion decomposition in advanced liquid electrolytes is demonstrated as an efficient approach to stabilize the Li metal anode, however, is electrolyte-dependent with limited application conditions due to inappropriate electrolyte properties. Herein, an efficient structuration strategy is proposed to fabricate an electrolyte-independent and sustained inorganic-rich layer, by embedding a type of functional anion aggregates consisting of selected anions ionically bonded to polymerized cation clusters. The anion aggregates can progressively release anions to react with Li+ and form key components boosting the structural stability and Li+ transfer ability of the artificial layer upon cycling. This self-reinforcing working mechanism endows the artificial layer with a sustained inorganic-rich nature and promising Li protective ability during long-term cycling, while the electrolyte-independent property enables its applications in LMBs using conventional low concentration electrolytes and all-solid-state LMBs with significantly enhanced performances. This strategy establishes an alternative designing route of Li protective layers for reliable LMBs.

Ferroelectric film materials have attracted significant interest due to their potential for harvesting various forms of clean energy from natural environmental sources. However, the photoelectric performance of these materials is frequently constrained by heat generation during light absorption, resulting in significant thermal losses. Most of ferroelectric films produce photocurrent and thermocurrent with opposite polarity, thus weakening the coupled photo-thermoelectric output of the devices. Here we report on a LaNiO3/BiMn2O5(BMO)/ITO ferroelectric film to produce photocurrent and thermocurrent with the same polarity. The polarity of the photocurrent generated by the BMO film is shown to be determined solely by the direction of spontaneous polarization, overcoming the detrimental effect of Schottky barrier for energy harvesting in device. We propose a new strategy to enhance the coupling factor, thereby offering valuable new insights for optimizing the utilization of ferroelectric materials in both light and heat energy applications.
