Comprehensive Characterization of the Immune Microenvironment Based on Nested Resampling Machine Learning Framework Identifies TRAF3 Interacting Protein 3 as a Promising Regulator to Improve the Resistance to Immunotherapy in Glioma

open access: yesAdvanced Science, EarlyView.
This study develops a nested resampling machine learning framework to establish the Immune Glioma Survival Signature (IGLoS), which stratifies glioma patients and predicts immunotherapy resistance. Multi‐omics analyses reveal TRAF3IP3 as a pivotal regulator of PD‐L1 expression and T‐cell exhaustion via ERK‐NFATC2 signaling.

Discharge Rate‐Driven Li2O2 Growth Exhibits Unconventional Morphology Trends in Solid‐State Li‐O2 Batteries

open access: yesAngewandte Chemie, EarlyView.
The morphology of lithium peroxide (Li2O2) in solid‐state Li‐O2 batteries (LOBs) is investigated using a polymer‐based solid electrolyte. Contrary to liquid systems, larger Li2O2 particles form at higher discharge rates due to space charge layer effects and heterogeneous interfaces. An optimal discharge rate is identified to balance ORR/OER efficiency,
