Remarkably, the effect presents the same magnitude as high-quality crystalline CMG with the L2<sub>1</sub> structure. The elastic neutron scattering peak in a-CMG is centered close to the crystalline phase, indicating that the amorphous material presents similar local atomic environments and magnetic interactions. First-principles density functional theory calculations further show that the anomalous Hall conductivity arises only when the local environments in the amorphous structure are similar to the L2<sub>1</sub> phase.

The LIFES exhibits physiology-mimicking paracrine effects, including sustained (∼192 h), phase-specific exosome secretion with tunable contents (∼8-fold increases) and programmable microRNA (miRNA) cargoes (initially pro-angiogenic and later pro-neurogenic), which overcome the limitations of the existing exosome delivery systems, such as short lifetime (∼24–48 h), difficult-to-preserve bioactivity, and non-changeable cargoes.

Understanding the origin of iridium dioxide dissolution at the nanoscale is crucial for the development of next-generation electrocatalysts that efficiently utilize iridium to meet energy demands. Herein, we report the influence of structural disorder, modulated by synthesis temperature, on the nanoscale dissolution dynamics and electrocatalytic activity of iridium dioxide nanocrystals. Our observations of dissolution on single nanocrystals revealed that structural disorder destabilized the OER-inactive (111) facets and had no substantial effect on the stability of the OER-active (110) facets.

According to the grazing-incidence wide-angle X-ray scattering (GIWAXS) results, in-plane compression enhances the stability of perovskites, whereas out-of-plane compression has a detrimental effect. Specifically, out-of-plane compression can lead to the formation of an inactive δ-phase, which compromises the stability of the perovskite.
