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.

Huli yanjiu, 1992 头孢菌素是一类半合成广谱抗生素,属于B—内酰胺抗生素范畴。近年来我国随着头孢菌素类抗生素在临床的广泛应用。就用于临床的可达30—40种。在日本头孢菌素类抗生素的应用已大大超过了青霉素,成为治疗细菌感染性疾病应用最多的抗生素。发生过敏反应的病例也屡有报道。鉴于头孢类抗生素与青霉素之间有不同的交叉过敏反应,头孢菌素类过敏者均对青霉素过敏。而青霉素过敏者中约有10％对头孢菌素类也能引起过敏反应,儿童过敏反应低于成人5 ...

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 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.
