Aqueous manganese-ion batteries (AMIBs) have emerged as a promising alternative in aqueous rechargeable batteries. However, AMIBs still face critical challenges, including insufficient stability of cathode materials, limited reversibility of the anode, and a restricted electrochemical stability window. Addressing these issues requires in-depth understanding of the underlying reaction mechanisms and formulation of effective strategies. This review systematically provides an overview of the latest advances in AMIBs, critically assesses the main challenges that hinder their practical application, and highlights innovative approaches to overcome these obstacles. Key strategies related to the design and modification of anode and cathode materials with optimized energy storage mechanisms, as well as the fine-tuning of electrolyte compositions, have been comprehensively dissected. Ultimately, this review aims to delineate future research directions and bridge the gap between advances in basic materials and industrial deployment, thereby accelerating the large-scale commercialization of aqueous batteries.

Metal halide perovskites have rapidly emerged as core candidate materials for the next generation of luminescence technologies. Blue perovskite light-emitting diodes (PeLEDs) based on these materials still exhibit great room for improvement compared with other emission colors. Studies have revealed that the primary limitations of blue PeLEDs arise from energy-level mismatches and low radiative recombination rates. Therefore, understanding and controlling the underlying carrier dynamics is crucial for advancing blue PeLEDs. This review first provides a systematic introduction to the characteristics and carrier dynamics process from a fundamental perspective. It also incorporates theoretical simulations, stability analyses, and discussions of defects to address the unique carrier dynamics requirements of blue PeLEDs. The strategies to tune these processes, including structural design and component optimization, are then summarized. Finally, the critical role of carrier dynamics in both fundamental physics and device performance of blue PeLEDs is clearly articulated.

Exploring potential superconductivity in magnetic compounds stands as a pivotal and challenging frontier issue. Low-dimensional materials, with their distinctive quantum confinement effects, provide an unparalleled platform for probing such quantum phenomena. Here, we present the discovery of pressure-induced superconductivity in novel antiferromagnetic CrNbSe5 microwires with a distinctive quasi-one-dimensional structure. Under compression, CrNbSe5 exhibits superconductivity at 15.0 GPa accompanied by carrier-type switching. The superconducting transition temperature reaches a maximum of 6.0 K at 34.2 GPa. Detailed structural analyses and theoretical calculations corroborate the quantum effects arising from Lifshitz transitions. Additionally, phonon softening and enhanced interchain interactions facilitate pressure-induced superconductivity. These findings offer critical insights into the mechanisms underlying pressure-induced superconductivity and its interplay with structural and electronic instabilities, accelerating the discovery of exotic quantum phenomena in low-dimensional van der Waals magnetic materials.

Data digitization of scientific literature is essential for creating machine-actionable knowledge bases to advance data-driven research and integrate with self-driving laboratories. It is especially critical to extract, interpret, and structure data from graphical elements, the primary medium for conveying complex scientific insights. However, this remains challenging due to the inherent lack of semantic structure in the prevalent PDF format, the complexity of visual content, and the need for multimodal integration. We present MERMaid (multimodal aid for reaction mining), an end-to-end pipeline that converts disparate visual data across PDFs into a coherent knowledge graph. Leveraging the emergent visual cognition and reasoning capabilities of vision-language models, MERMaid demonstrates chemical context awareness, self-directed context completion, and robust coreference resolution to achieve 87% end-to-end accuracy across three chemical domains. Its modular design facilitates future application to diverse data beyond reaction mining, promising to unlock the full potential of scientific literature for knowledge-intensive applications.

Chiral organic small molecules, recognized for their intrinsic chirality and tunable chiroptical properties, present a promising candidate for circularly polarized light (CPL) detection. However, they often exhibit low CPL absorption asymmetry factor (gabs) due to the lack of effective material design principles. Here, we conceptualize the group theory-guided material design principle and demonstrate high-performance CPL detection using doubly bridged naphthalene-1,8:4,5-bis(dicarboximide) cyclophanes ((+)/(−)-2NDI) as an example. The D2 point group endows (+)/(−)-2NDI with optimal angles—either 180° or 0°—between the magnetic and electric transition dipole moments, achieving a gabs of up to ±0.06, one of the highest values reported for chiral organic semiconductors. This strategy has facilitated CPL photodetectors with a photocurrent asymmetry factor (gph) of 1.67, far surpassing most of the current CPL photodetectors. Our group theory-guided material design principle offers a robust framework for designing polarization-sensitive materials, heralding new possibilities for integrated chiroptical devices.

The increasing electromagnetic pollution necessitates the development of advanced microwave absorbers. Although MAX phases exhibit chemical stability and electrical conductivity, their absorption performance is limited by a singular loss mechanism. Here, we propose a “pre-placed vacancy and isomorphous occupancy” strategy to engineer A-site high-entropy (HE) MAX phases, achieving unprecedented incorporation of large-radius elements (Ag and Bi). The optimized absorber delivers exceptional microwave absorption performance, with a minimum reflection loss of −71.6 dB (at 3.05 mm) and a broad effective absorption bandwidth of 4.1 GHz (at just 1.25 mm), outperforming both reported MAX phase variants and commercial absorbers. These remarkable properties stem from three synergistic mechanisms: A-site composition tailoring optimized impedance matching, HE-induced lattice distortion enhanced dipolar polarization, and A-site entropy engineering increased conduction loss. Our work pioneers a novel method for manipulating electromagnetic response in MAX phases through atomic-scale entropy engineering, paving the way for next-generation electromagnetic protection materials.
日益严重的电磁污染要求研制先进的微波吸收器。尽管MAX相具有化学稳定性和导电性，但其吸收性能受到单一损耗机制的限制。在这里，我们提出了一种“预先放置空位和同构占用”策略来设计a点高熵（HE） MAX相，实现了前所未有的大半径元素（Ag和Bi）的结合。优化后的吸收器具有卓越的微波吸收性能，最小反射损耗为- 71.6 dB (3.05 mm)，有效吸收带宽为4.1 GHz（仅1.25 mm），优于报道的MAX相位变体和商用吸收器。这些显著的性能源于三种协同机制：a位组成裁剪优化阻抗匹配，he诱导的晶格畸变增强偶极极化，a位熵工程增加传导损耗。我们的工作开创了一种通过原子尺度熵工程操纵MAX相电磁响应的新方法，为下一代电磁保护材料铺平了道路。

The spatial structure of metamaterials can be designed to focus deformations or waves at a specific location. However, input control of this behavior, allowing for focusing waves at multiple targeted locations, remains challenging. Here, we exploit frequency as a control parameter and show that frequency-controlled wave focusing can be realized by rationally pruning random elastic networks. Our approach is robust, and we also demonstrate such wave focusing experimentally. Our study revises the concept of wave focusing and opens up a viable route for the design of new generations of acoustic sensors, energy harvesters, lenses, and programmable acoustic media, free from the limitations imposed by periodicity.

Conventional MAX phases face limitations in microwave absorption due to poor impedance matching and a singular loss mechanism. To address these challenges, recently, in Matter, Tian et al. proposed an innovative “pre-placed vacancy and isomorphous occupancy” strategy to prepare the first A-site high-entropy MAX phase. The entropy-induced lattice distortions and defects optimize impedance matching and enhance polarization loss, thus achieving exceptional microwave absorption. This work establishes A-site high-entropy engineering as a powerful approach to tailor MAX phases for next-generation microwave absorption materials.
