Understanding Flood Fatalities: Reevaluating Flood Risk Management

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Extraordinary flooding in July 2021 claimed 224 lives in Germany and Belgium, an unprecedented number in recent decades in both countries. To better understand the underlying causes, individual circumstances of all fatalities were analyzed based on official documents and interviews with family members.

Cross‐Correlations of Solar Wind Parameters Using Monitoring Spacecraft

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Space weather predictive modeling currently utilizes real‐time data from the spacecraft ACE and DSCOVR, with SOLAR‐1 and IMAP recently online. This study assesses whether DSCOVR solar wind plasma and interplanetary magnetic field (IMF) data exhibit large‐scale discrepancies from the corresponding ACE data, and if so, whether these ...

The Ionosphere as an Operational Constraint on Space‐Based Solar Power

Space Weather, Volume 24, Issue 9, September 2026.
Abstract This commentary argues that there is an urgent need to develop a scientific consensus on how microwave beams from space‐based solar power (SBSP) satellites will interact with plasma in the ionosphere. Whilst the SBSP concept dates back to the 1970s, it is now gaining traction around the world as a technology that could contribute baseline ...

Robust Antiferroelectric Response in the Pbca Phase of Hafnium Zirconium Oxide via Aluminum Substitution

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT Hafnium zirconium oxide (HZO) has attracted attention for applications in nonvolatile memory and energy harvesting devices. However, it faces practical challenges such as insufficient endurance. One promising strategy to address this limitation is the utilization of antiferroelectric (AFE) behavior in HZO‐based materials. Previous studies have

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2284-2302, September 2026.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not
