However, their single‐loss mechanism often restricts the effective bandwidth, while traditional carbon‐based EMW absorbing materials face constraints owing to expensive raw materials and complex synthesis processes, hindering industrialization. To address these challenges, we utilize cost‐effective and readily available metal phthalocyanine as a precursor. The incorporation of magnetic metal components induces magnetic loss mechanisms that effectively compensate for the predominant dielectric characteristics of the carbon matrix. Through a simple grinding and carbonization process, metal nanoparticles are uniformly dispersed within a nitrogen‐doped carbon matrix, thereby creating numerous defects and abundant heterogeneous interfaces. The resulting composites exhibit exceptional EMW absorption, attributed to synergistic multiple‐loss mechanisms. Notably, the CuCoNiZn/NC composite attains an effective absorption bandwidth (EAB) of 5.6 GHz, while the Cu/NC composite achieves a minimum reflection loss (RL min ) of −53.7 dB with an EAB of 5.52 GHz. Additionally, CST simulations validate the practical applicability of the absorber. This study presents a viable pathway for industrializing high‐performance wave‐absorbing materials.","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 11","pages":"8899-8910"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147891521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a novel approach utilizing ferritin-based nanocarriers [HFn(+)] for the targeted delivery of doxorubicin (DOX), combined with CpG oligodeoxynucleotides as an immune adjuvant, to enhance the immunogenicity and therapeutic efficacy against lung cancer.

Despite their potential, the widespread clinical adoption of Zn alloys has been hindered by insufficient mechanical properties, design limitations of traditional manufacturing, and limited clinical validation. Recent advances in additive manufacturing (AM), particularly laser powder bed fusion (LPBF), are revolutionizing the production of Zn alloy implants. LPBF enables unprecedented design freedom and accuracy, allowing the fabrication of patient-specific, geometrically-intricate and porous structures with unique functionality that are previously unattainable. This review aims to provide a comprehensive overview of the latest progress in LPBF processing of Zn alloys, focusing on structure design, fabrication, microstructural characteristics, and mechanical and biological properties—critical factors for real applications of functional implants, particularly in cardiovascular and orthopedic fields. Additionally, this review examines the role of post-processing treatments, such as heat treatments and surface modifications, in adjusting degradation rate, controlling Zn<sup>2+</sup> ion release, and improving cell viability, proliferation and differentiation, all of which are vital for achieving predictable and reliable in vivo outcomes. Further, the review seeks to synthesize these advances and their interplays to provide a strategic insight for translating patient-specific, biodegradable Zn implants into clinical practice.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 11","pages":"8262 - 8291"},"PeriodicalIF":11.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12598-025-03518-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145469331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
