Enhancing Low‐Latitude Ionospheric Irregularity Prediction With Generalized Linear Models

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The ionosphere poses challenges for accurate forecasting due to its complexity and variability. Irregularities in the lower ionosphere are influenced by local time, season, geographic location, solar activity and space weather, complicating precise predictions.

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Characterizing North‐South Ionospheric Gradients During Geomagnetic Storms: A Variogram Enhancement for Wide Area Ionospheric Models

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The intensified solar maximum of Cycle 25 has heightened space weather risks to Global Navigation Satellite Systems (GNSS), where geomagnetic storms critically challenge Positioning, Navigation, and Timing (PNT) availability. Current wide‐area ionospheric models may fail to resolve extreme latitudinal Total Electron Content (TEC) gradients ...
