Electromagnetic Ion Cyclotron Waves in the Initial Phase of Geomagnetic Storms

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Using simultaneous magnetic field observations from 10 satellites and an automated detection algorithm, we identify broad regions of electromagnetic ion cyclotron (EMIC) wave activity during the initial phases of geomagnetic storms between September 2015 and October 2019.

Is the Magnetic Field Line Curvature Really Important for Energetic Electron Losses From the Radiation Belt?

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Recently, Hua et al. (2026, https://doi.org/10.1029/2025GL120881) combined observations during a 4‐day storm period with numerical simulations and concluded that the abrupt electron loss in the field‐line‐curvature scattering (FLCS) region played a leading role in shaping the outer boundary of radiation belt (RB); the authors conjectured that ...

Spectroscopic Investigation of the In Vivo Light‐Dependent Photodynamics of the Marine Diatom Phaeodactylum tricornutum

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.
µm fourier transform infrared (FTIR) image, 442 nm Raman of the Si–O of the silica‐based frustule at 472 cm−1, and UV–vis of Phaeodactylum tricornutum cells. Marine diatoms are responsible for fixing CO2 into organic carbon and contribute to the regulation of global climate.

Photon Recycling–Driven Photodetection Enhancement in Ni(AcO)2–MAPbBr3 Nanocomposite Waveguides

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Photon recycling is demonstrated as an effective mechanism to enhance perovskite photodetector performance. A Ni(AcO)2/MAPbBr3 nanocomposite waveguide enables long‐range propagation and reabsorption of photoluminescence photons, increasing photocurrent by ∼60%. Under pulsed excitation, reabsorption of amplified spontaneous emission further enhances the
