Ultra‐High‐Capacity of Earth‐Abundant Cathodes Enabled by Excess Fluoride‐Ion Insertion/Extraction

Advanced Energy Materials, Volume 15, Issue 29, August 5, 2025.
A perovskite oxyfluoride SrFeO2Fx can accomodate excess F– beyond x = 1 in the structure with oxygen redox (O–O bond formation). The Sr‐substituted CaFeO2Fx (Ca0.8Sr0.2FeO2Fx) provides an extremely large capacity of 580 mAh g−1 (2595 mAh cm−3). This research will provide new design principles for the development of all‐solid‐state fluoride‐ion battery ...

Recovery of lacustrine ecosystems after the end-Permian mass extinction [PDF]

, 2020
The end-Permian mass extinction (EPME; ca. 252 Ma) led to profound changes in lacustrine ecosystems. However, whether or not post-extinction recovery of lacustrine ecosystems was delayed has remained uncertain, due to the apparent rarity of Early and ...

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction

Advanced Science, Volume 12, Issue 25, July 3, 2025.
Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...
