研究通过XAFS和Mössbauer谱学分析纯化Giese盐的多级自旋弛豫和键长变化，揭示其在生物医学中的潜在应用价值

摘要：

铵铁六氰铁酸盐是一种兽医医学里程碑，是放射性铯的解毒剂，众所周知的Giese盐在切尔诺贝利事故后被喂给家畜和野生动物，它在纳米结构化学和铁磁性中表现出丰富的相互作用。在广泛的分析技术中，宏观微米级聚集体和纳米粒子尺寸的双重性，以及通过Fe K边XAFS结果建议的Fe(II)-C≡N-Fe(III)键长的扩大，以及在^57Fe莫塞莱谱学中的多级自旋弛豫被突出显示。这使这种被低估的化合物在新的光线下呈现，例如在现代生物医学和生物功能方面，扩展了其在除假设未来核事故外的重要作用

英文摘要：

Ammonium ferric hexacyanoferrate is a veterinary-medical milestone and antidote against radiocesium, well-known as Giese-salt after the Chernobyl disaster fed to domestic and wild animals, which shows even a rich interplay of properties in nanostructural chemistry and ferromagnetism. Among the broad analytical techniques, the ambivalence of macroscopic micrometer-sized agglomerates and nanoparticle sizes, a suggested enlarged Fe(II)$-$C$\equiv$N$-$Fe(III) bond length by Fe K-edge XAFS results and multi-level spin relaxation in $^{57}$Fe Mössbauer spectroscopy are highlighted. This sets this underestimated compound in a new light, e.g., for modern biomedicine and biofunctionality, extending its essential importance in addition to hypothetical future nuclear incidents
