Owing to their exceptional properties, high-entropy alloys(HEAs) and high-entropy materials have emerged as promising research areas and shown diverse applications. Here,the recent advances in the field are comprehensively reviewed,organized into five sections. The first section introduces the background of HEAs, covering their definition, significance,application prospects, basic properties, design principles, and microstructure. The subsequent section focuses on cutting-edge high-entropy structural materials, highlighting developments such as nanostructured alloys, grain boundary engineering,eutectic systems, cryogenic alloys, thin films, micro-nano-lattice structures, additive manufacturing, high entropy metallic glasses, nano-precipitate strengthened alloys, composition modulation, alloy fibers, and refractory systems. In the following section, the emphasis shifts to functional materials, exploring HEAs as catalysts, magneto-caloric materials, corrosion-resistant alloys, radiation-resistant alloys, hydrogen storage systems, and materials for biomedicine. Additionally, the review encompasses functional high-entropy materials outside the realm of alloys, including thermoelectric, quantum dots, nanooxide catalysts, energy storage materials, negative thermal expansion ceramics,and high-entropy wave absorption materials. The paper concludes with an outlook, discussing future directions and potential growth areas in the field. Through this comprehensive review,researchers, engineers, and scientists may gain valuable insights into the recent progress and opportunities for further exploration in the exciting domains of high-entropy alloys and functional materials.

Estimating battery degradation is vital not only to monitor battery’s state-of-health but also to accelerate research on new battery chemistries. Herein, we present a data-driven approach to forecast the capacity fading trajectory of lab-assembled lithium batteries. Features with physical meanings in addition to predictive abilities are extracted from discharge voltage curves, enabling online prediction for a single cell with only its historical data. The robustness and generalizability allow for the demonstration on a compromised quality dataset consisting of batteries varying in battery architectures and cycling conditions,with superior accuracy for end of life and degradation trajectory prediction with average errors of 8.2.and 2.8%, respectively. Apart from the impressive prediction accuracy, the as-extracted features also provide physical insights, the incorporation of which into material design or battery operation conditions further enlightens the development of better batteries. We highlight the effectiveness of time-seriesbased techniques in forecasting battery cycling performance, as well as the huge potential of datadriven methods in unveiling hidden correlations in complicated energy chemistries such as lithium metal batteries.

为了研究二茂铁衍生物在HTPB推进剂中的迁移规律及对推进剂燃速的催化作用,利用“三明治”试件模拟70℃下二茂铁类衍生物在HTPB推进剂体系中的迁移过程,并以此来评价二茂铁衍生物的迁移性能;在相同HTPB推进剂配方条件下,测定了不同二茂铁衍生物对推进剂燃速的催化作用;通过Gaussian程序计算得到二茂铁衍生物的偶极矩、能量等理论性质,并分析与测试结果之间的关系。结果表明,二茂铁衍生物的分子偶极矩与取代链段密切相关,增塑剂癸二酸二异辛酯分子的偶极矩受链段构象的影响明显,常温下趋向于偶极矩较大的构象,高温下则趋向于偶极距较小的构象;根据建立的“溶解-解析”模型分析得出,二茂铁衍生物的偶极矩与增塑剂的偶极距越接近,迁移率越小;在对HTPB推进剂燃速的催化作用上呈现出二茂铁衍生物的铁含量越高,二茂铁衍生物HOMO与LUMO的能量差越小,催化作用越明显。
