Potassium-ion batteries (PIBs) were recognized for their natural abundance, high theoretical output voltage, and the availability of commercialized graphite anodes. However, the development of high-performance manganese-based layered oxide cathodes—a leading candidate for PIB systems—has been fundamentally constrained by irreversible phase transitions (PT) during the cycling process, manifesting as severe structural degradation and capacity fading. This review presents a transformative paradigm integrating machine learning (ML) with multiscale characterization to analyse the complex phase transition mechanisms in Mn-based cathodes. Through systematic ML-driven interrogation of structure–property relationships, we establish quantitative descriptors for phase stability and develop predictive models for transition dynamics. Furthermore, we highlight recent breakthroughs in cross-disciplinary approaches, enabling the rational design of PT-mitigated cathode architectures. By consolidating these insights into a unified knowledge framework, this work provides strategic guidelines for developing structurally robust Mn-based cathodes and outlines future research directions for next-generation PIB systems. © 2025 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

Solar-driven water purification is recognized as an effective and sustainable technology for tackling the global water crisis by utilizing clean and renewable solar energy. In this study, we present a mussel-inspired MXene-functionalized sponge (denoted as POPM sponge), which features a 3D interconnected porous structure, enhanced surface hydrophobicity, and efficient photothermal conversion capabilities. The design and fabrication of the POPM sponge involve integrating mussel-inspired hydrophobic Ti3C2Tx MXene nanosheets with a 3D interconnected porous PDMS sponge as precursors. This POPM sponge shows considerable potential as a multifunctional photothermal material to promote solar-driven water purification in complex wastewater systems. With its superior surface hydrophobicity and high photothermal conversion efficiency, this POPM sponge effectively recovers high-viscosity crude oil spills through photothermal-driven absorption. Moreover, it functions as an efficient solar evaporator, exhibiting high water evaporation rates and remarkable photothermal conversion efficiencies, thereby facilitating cost-effective solar-driven water purification in complex wastewater systems. Additionally, it possesses remarkable photothermal antibacterial characteristics for the sterilization of common pathogenic bacteria in wastewater, indicating its potential as a promising photothermal material for sterilization applications in such environments. This strategy offers a pathway for the development of multifunctional photothermal materials aimed at enhancing the efficiency of solar-driven water purification in complex wastewater systems within practical applications. © 2025 Elsevier B.V.

Handling water is a critical challenge for proton exchange membrane (PEM) fuel cells, significantly impacting their lifespan and reliability. While most PEM cells operate in vibrational environments, no studies have examined how mechanical vibrations affect water handling. This research investigates water droplet behavior in a vibrating airflow channel and proposes a new design featuring a hydrophilic band to enhance water management. key findings include: (1) an optimal hydrophilic band width of 0.6 that facilitates droplet movement;(2) a decrease in droplet velocity from 0.107 to 0.024 m s−1 as amplitude increases from 5 mm to 20 mm;and (3) an increase in velocity from 0.0669 to 0.15 m s−1 with higher frequency, highlighting the significant effects of vibration on droplet dynamics and overall water management in PEM fuel cells. © 2025 Institution of Chemical Engineers

To date, cyclodextrins (CDs) and their derivatives are recognized as highly effective chiral selectors in electrophoresis for enantiomer separation due to their numerous advantages. In this study, three amino-β-CD derivatives, including NH2-β-CD-5 (Mono-(6-(tetraethylenepentamine)-6-deoxy)-beta-Cyclodextrin), NH2-β-CD-3 (mono-(6-(diethylenetriamine)-6-deoxy)-β-Cyclodextrin), and NH2-β-CD-1 (6-Monodeoxy-6-monoamino-beta-cyclodextrine) with varying amino substituent chain lengths were employed as chiral selectors in capillary electrophoresis (CE) to examine their chiral selectivity in the separation of five dansylated amino acid enantiomers, namely Dns-DL-Val, Dns-DL-Leu, Dns-DL-Thr, Dns-DL-Phe, and Dns-DL-Ser, as the chain length of the substituent group significantly impacts separation performance. Among the three amino-β-CD derivatives, NH2-β-CD-5 exhibited superior performance by separating four dansylated amino acid enantiomers, whereas NH2-β-CD-3 and NH2-β-CD-1 separated only two and one enantiomers, respectively. Additionally, the effects of pH values, buffer concentrations, and concentrations of the chiral selectors on the separation of dansylated amino acid enantiomers were also investigated. Furthermore, the stability and reproducibility of the three amino-β-CD derivatives were evaluated, with the relative standard deviations (RSDs) of resolution all below 8.2 %. © 2025

Resilient ultrafine fiber sponges with thermal bridge structures for high-temperature traffic noise reduction

引用

Journal of Colloid and Interface Science 2025年 693卷 137634页

作者： Li, Yanzhe Zong, Dingding Sun, Yaning Pang, Shuying Liao, Yalong Liu, Yong Ministry of Education Key Laboratory for Advanced Textile Composite Materials School of Textile Science and Engineering Tiangong University Tianjin300387 China Aerospace Institute of Advanced Material & Processing Technology Beijing100074 China

With the expansion of the transportation business, noise pollution has seriously affected human health and quality of life. Vehicles not only generate noise but also release a large amount of heat, existing traffic noise reduction materials have no thermal conductivity and poor low-frequency noise reduction. Herein, thermal bridge structured elastic ultrafine fiber sponges (TBFSs) were constructed in one step through simultaneous high-humidity assisted electrospinning and electrospraying. The thermal bridge structures endow fiber sponges with good thermal conductivity (close to 0.1 W m−1 K−1), increased by 350 % compared with common fiber sponges. More importantly, due to the complex pore channel and the vibration effect of the thermal bridge structures, the TBFSs achieve a high noise reduction coefficient of 0.58, which can reduce the high-temperature white noise by 16.5 dB at 100 °C. Besides, the synergistic effect of elastic polyurethane and heat crosslinking endows TBFSs with good mechanical properties, demonstrating negligible plastic deformation following 100 cycles of compressive loading. The successful development of thermal bridge structures fiber sponges provides a new solution for high-temperature safety noise reduction. © 2025 Elsevier Inc.
