On this matter, we have discussed model selection in machine learning modeling, the issues encountered, and the limitations of the composition-focused approach. Through insights gained from research in other material fields, it is highlighted that integrating machine learning with other computational methods such as first-principles calculations and phase diagram computations can significantly enhance the predictive capabilities of machine learning.

The stretchability and stability of solid metal-based stretchable electrodes are still limited due to their intrinsic rigidity. Liquid metals are one of the most popular materials for stretchable electrodes due to their high conductivity, flexibility, and machinability. However, the surface tension of liquid metals is extremely high at room temperature, hindering their applications. In this review, recent developments of liquid metals as conductive fillers in the field of stretchable electrodes are reviewed in detail firstly. Besides, the combination of liquid metals on different substrates according to their types is classified and summarized. Furthermore, the applications of liquid metal-based flexible electronics with single and multiple functions are systematically discussed. A brief perspective for future research is given.

Studying negative thermal expansion (NTE) materials has been a hot issue in modern physics and material science because mechanisms of NTE cannot be understood by general thermal expansion theory, and NTE materials have the potential to fabricate zero thermal expansion materials by combination with positive thermal expansion (PTE) materials. NTE materials with a wide working temperature range are mainly ceramics or insulators. However, in 2022, uniaxial NTE along the <i>c</i>-axis in a wide temperature range was observed in CuAl₂-type tetragonal CoZr₂ superconductor. Since superconductors with a wide temperature range of NTE are quite rare, the discovery has attracted attention and plays an important role in leading further studies. In this article, we review the recent progress of the study on transition metal (<i>Tr</i>) zirconide <i>Tr</i>Zr₂ with its unique NTE phenomena. We discuss how to control the uniaxial NTE along the <i>c</i>-axis and the mechanisms of the NTE for <i>Tr</i>Zr₂.

To address this issue, Bi₂Se₃-modified porous MXene (Bi₂Se₃-MXene-P) films with highly porous structure were selectively prepared using a template method, the prepared films exhibit large specific surface area, good conductivity, high volumetric capacity, and excellent flexibility. The introduction of Bi₂Se₃ acts as the spacers can not only effectively prevent the restacking of single-layer MXene but also enlarge the interlayer distance of MXene, leading to increased surface area and improved electrolyte electron transportation. More importantly, Bi₂Se₃ can provide more active sites to further improve the electrochemical performance in capacitor application. Benefiting from these properties, the Bi₂Se₃-MXene-P film electrode shows outstanding volumetric capacities of 1407.6 F cm⁻³ at 0.5 A g⁻¹ in 1M AlCl₃ electrolyte. To assess the electrochemical behavior for practical applications, the Bi₂Se₃-MXene-P//Al soft-pack devices were assembled. Volumetric capacities of the Bi₂Se₃-MXene-P//Al soft-pack devices decreased from 214.1 F cm⁻³ at 0.5 A g⁻¹ to 115.7 F cm⁻³ at 5 A g⁻¹. Additionally, when it switched back to 0.5 A g⁻¹, the volumetric capacity could recover to 210.1 F cm⁻³ demonstrating its excellent rate capability. Moreover, the Bi₂Se₃-MXene-P//Al soft-pack Al-ion device exhibits the capacitance retention of 77.4% after 5000 charge–discharge cycles. The device also displays a high energy density of 14.8 Wh kg⁻¹ at 130.7 W kg⁻¹ power density. The present work demonstrates the potential application of the Bi₂Se₃-MXene-P film electrode in flexible energy storage devices.</p>","PeriodicalId":100919,"journal":{"name":"MetalMat","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/metm.33","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This novel material class not only opens up extensive potential for materials discovery through a broad spectrum of elemental combinations but also facilitates fine-tuning of properties thanks to its distinctive microstructural characteristics. HEMs have garnered considerable attention across various applications, particularly in catalysis. The virtually infinite variations in elemental and compositional combinations within these multi-elemental systems enable meticulous optimization of the catalytic performance. Additionally, the high-entropy solid-solution structure potentially enhances structural, thermal, and chemical stability, which is vital for ensuring functionality under harsh conditions. Herein, we thoroughly explore the exceptional attributes of HEMs, designing strategies for transition metal-based catalysis, and three major catalytic fields of HEMs: electrocatalysis, photocatalysis, and thermocatalysis.
