Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT High‐strength aluminum (Al) alloys are usually unprintable by laser powder bed fusion (LPBF) due to the severe hot cracking along the columnar grains. Doping elements scandium (Sc) and/or zirconium (Zr) is an effective way to eliminate hot cracks by refining the grain size to nearly nanoscale levels.

, 2007 “S-诱抗素”(学名:天然脱落酸,简称:S-ABA)与生长素、赤霉素、细胞分裂素、乙烯并列为世界公认的5大类天然植物生长调节物质,它既是植物的“抗逆免疫物质”也是植物的“生长平衡因子”。当植物遭受逆境胁迫时,“S-诱抗素”在细胞间传递逆境信息,诱导植物机体产生各种相对应的抵抗能力,提高植物抵抗盐碱、干旱、低温冷害、高温风害、水涝等的能力,从根本上防止病虫害的发生,强力促进生根,诱导大量侧根和根毛的生成,增强对水肥的吸收能力。“S-诱抗素”能够大幅度提高困难地造林的成活率和保存率 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...
