Lightning Outbreaks at the Mature Stage of Tropical Cyclone: Case Study for Hurricane Dorian (2019)

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The relationship between tropical cyclone (TC) lightning activity and intensity change has been examined for nearly 30 years, yet a clear consensus remains elusive, reflecting the complexity of the processes governing TC lightning. This study investigates the physical mechanisms that triggered inner‐core lightning outbreaks during the mature ...

Spin‐Selective Interface Engineering in Oxide–Ferromagnetic Junctions via Atomic‐Scale Oxygen Control

Advanced Science, Volume 13, Issue 25, 4 May 2026.
We show that interfacial oxygen at the MgO/Fe interface can be transformed from an uncontrolled variable into a tunable design parameter for spintronic junctions. Momentum microscopy provides direct access to the momentum‐ and spin‐resolved electronic structure beneath the insulating MgO layers, revealing how oxygen intercalation reshapes buried Fe ...

Photonuclear Population of 229m,gTh in Th‐Doped Crystals Toward Nuclear Clock Development

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.
