Hard carbon, a leading anode for sodium‐ion batteries (SIBs), suffers from nonuniform sodium deposition, which causes dendrite growth and compromises safety and cycle life. Here, we report a closed‐pore engineering strategy based on cobalt‐doped hard carbon (CoHC) that couples internal sodium‐cluster confinement wi...
Geostationary hyperspectral infrared sounders provide hourly observations of the atmospheric composition. However, the conventional optimal estimation method (OEM)‐based retrieval algorithm requires computationally expensive radiative transfer calculations and inverse modeling, making it difficult to monitor in rea...

Satellite retrievals of the dry-air column-averaged mole fraction of methane (XCH4) contain substantial spatial gaps, limiting monthly comparisons over a fixed domain. We developed CatBoost (CATB), random forest (RF), and multilayer perceptron (MLP) models to reconstruct spatially complete monthly XCH4 fields over Chin...
