Unveiling the Structural Origins of Dynamic Diversity in Pd-Based Metallic Glasses.

The β-relaxation is one of the major dynamic behaviors in metallic glasses (MGs) and exhibits diverse features. Despite decades of efforts, the understanding of its structural origin and contribution to the overall dynamics of MG systems is still unclear. Here two palladium-based Pd─Cu─P and Pd─Ni─P MGs are reported with distinct different β-relaxation behaviors and reveal the structural origins for the difference using the advanced X-ray photon correlation spectroscopy and absorption fine structure techniques together with the first-principles calculations.

[Genetical investigation on a rare genealogy of congenital camptodactyly].

Introduced a rare genealogy of autosomal dominant inheritance disease, which cardinal signs were congenital camptodactyly and functional disturbance of the proximal interphalangeal joints of the II, III, IV, V fingers. Part cases had congenital high myopia.
