Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

open access: yesTerra Nova, EarlyView.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Primitive Ligands Drive 1D CsPbI3 Nanostructures with Strongly Polarized Photoluminescence

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
This work illustration highlights I− concentration drives the structural evolution of CsPbI3 from cubic to orthorhombic phase, accompanied by octahedral distortion. In addition, increasing I− transforms nanorods into ginkgo‐leaf‐like assemblies, including a 659–683 nm PL redshift due to bandgap narrowing and strain effects.

On Wind Directions Estimated by Nacelle Lidar Under Different Reconstruction Methods

open access: yesWind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT The wind direction is closely linked to the power performance and structural loads of wind turbines. Conventional nacelle‐mounted vanes or sonic anemometers face errors associated with airflow distortions caused by turbine blades. Nacelle‐mounted lidar systems offer line‐of‐sight speed measurements from multiple positions ahead of the rotor ...

On the Beam Characteristics of X‐Ray Bursts Observed in Rocket‐Triggered Lightning

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Employing the multi‐station Thunderstorm Energetic Radiation Observation System, we detected X‐ray bursts during two rocket‐triggered lightning events in 2024. By innovatively integrating optical imaging with three‐dimensional lightning channel reconstruction based on Distributed Acoustic Sensing (DAS), we analyzed the X‐ray emission ...

On the Construction of Moho Reflected Shear Wave Phases From Ambient Noise

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Shear waves reflected from the Moho (SmS) are frequently identified in ambient noise cross‐correlation functions. Despite their consistent appearance across various arrays and studies, the physical origin and generation mechanisms of these SmS phases remain poorly understood.

The Magnetic Signature of Stress in Rocks

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Magnetic signatures preserved in rocks have long provided insight into Earth's evolution, revealing processes from plate tectonics to the habitability of Earth. While large impacts are known to impose extreme stresses (>1 GPa) and heat that fundamentally alters magnetic records, lower stresses typical of earthquakes have been considered ...

Observational Evidence for Wind‐Driven Low‐Pass Filtering of Infrasound at Short Range

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Infrasound from controlled explosions provides a unique opportunity to isolate atmospheric effects on propagation. We report observations from two campaigns in May and October 2024, each featuring 10‐ton TNT‐equivalent controlled surface chemical explosions recorded by a dense network of 31 single‐sensor stations within 23 km.

High‐Pressure Synthesis of Antimony Nitride Sb3N5 and Polynitride Sb2N8 Featuring Single‐Bonded N810− Chains

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 6, 2 February 2026.
High‐pressure reactions between Sb and molecular nitrogen in a laser‐heated diamond anvil cell led to the formation of oC32‐Sb3N5 (51(1) GPa) and mP20‐Sb2(N8), (> 100 GPa). Both phases were identified by single‐crystal x‐ray microdiffraction and are fully corroborated by density functional theory calculations.
