Quasi‐Trapped Zebra Stripes: Radial Transport Driven by Dual‐Pulse Electric Fields
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Energetic electron spectra in Earth's inner radiation belt often exhibit regular stripe‐like features, known as “zebra stripes,” which are typically attributed to the drift motion of stably‐trapped electrons disturbed by electric field perturbations.

Polarons in Heterogeneous Photo(electro)Catalysts
Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.Polarons are defined as quasiparticles consisting of electrons/holes covered by a cloud of virtual phonons, which are beneficial/detrimental to the electronic properties of materials. This minireview provides a conceptual overview of how small polaron formation influences the photon absorption, charge transport and separation, and surface reactivity in

The Evolution of Hot Flow Anomalies in Martian Space Environment
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Hot Flow Anomalies (HFAs) are transient foreshock structures generated by solar wind discontinuity‐bow shock interactions, with their evolution only confirmed near Earth. Using MAVEN and Tianwen‐1 joint observations, we study the evolution of a Martian HFA event detected on 17 September 2022 (dayside by MAVEN, nightside by Tianwen‐1).

Self‐Refreshing Bi‐Based Active Sites for Efficient and Durable Electrochemical CO2 Reduction
Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.A self‐refreshing Bi‐based catalyst is developed through the fabrication of a novel basic bismuth nitrate pre‐catalyst, which exhibits differential active sites of Bi2O2CO3 at low potentials and metallic Bi phases at high potentials, self‐repairing capability, and thus wide‐potential‐window efficiency and ultralong durability toward electrochemical CO2
