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 ...

Shuitu Baochi Xuebao, 2005 本试验采用连续振荡法,初步研究了水溶性有机高分子材料聚乙烯醇、聚丙烯酰胺和聚乙二醇对磷在红壤中吸附过程的影响,并对该过程拟合出方程。结果表明:在聚乙烯醇、聚丙烯酰胺和聚乙二醇作用下土壤磷吸附动力学以幂函数方程为最优方程,且方程参数与单施磷酸二氢钙的处理方程参数有显著差异性。有机高分子能显著提高磷在红壤中的吸附和土壤pH,但材料之间的土壤吸附量无差异显著性,需进一步研究。

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.
