Intrinsic and Water‐Triggered Hydrophilicity in Tween 20‐PDMS Composites for Dynamic and Long‐Term Wettability Control

open access: yesSmall, Volume 22, Issue 24, 27 April 2026.
A one‐step bulk integration of the surfactant Tween 20 into PDMS enables intrinsic and water‐triggered hydrophilicity. Combined molecular simulations and experiments reveal a dual mechanism where bound and mobile Tween 20 molecules cooperatively induce self‐activating, stretch‐tolerant, and long‐term wettability, supporting self‐driven liquid transport,

N‐FOREWARNS: Regional Nowcasting of Surface Water Flooding With a 3‐h Lead Time Predictability Limit

open access: yesMeteorological Applications, Volume 33, Issue 2, March/April 2026.
N‐FOREWARNS produces surface water flood predictions on hourly lead times (nowcasting timescales). During a user engagement workshop, experts reported that N‐FOREWARNS produces few false alarms and high warning accuracy, but often misses minor impact floods.

Frequency-Voltage Active Support Strategy for Hybrid Wind Farms Based on Grid-Following and Grid-Forming Hierarchical Subgroup Control

open access: yesCSEE Journal of Power and Energy Systems
The GFL-GFM hybrid wind farm (HWF) combines the voltage source control advantages of grid-forming (GFM) wind turbines (WTs) with the current source control advantages of grid-following (GFL) wind turbines.

The SCEC Community Rheology Model for the Southern California Lithosphere: Geological Framework, Ductile Flow Laws, and Preliminary Implications

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Southern California Earthquake Center (SCEC) Community Rheology Model (CRM) comprises a three‐dimensional geologic framework model (GFM) of southern California's lithosphere, and synthetic aggregate ductile flow laws applicable to each GFM rock type under low‐strain conditions. Given temperature, volatile content, pressure, and strain rate,

Monitoring Flood Inundation Dynamics From Space

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Coordinated Planning of Flexible Interconnection and Grid-Forming Energy Storage in Low-Voltage Distribution Networks Considering Off-Grid Operation

open access: yesEnergies
Severe weather events increasingly threaten the reliability of low-voltage distribution networks (LVDNs). Existing fault restoration strategies primarily focus on medium-voltage networks, leaving LVDNs highly vulnerable during prolonged grid outages.

Geospatial Analysis of Population Exposure to Flooding in the Sudd Region, South Sudan

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The Sudd wetland in South Sudan extends over 90,000 km2. Large‐scale flood events in recent years (2019–2022) are said to have led to the displacement of an estimated 1.8 million people in total. However, these estimates are approximate and to date there has not been a systematic analysis of population exposure to flooding in the Sudd region ...

Worlding geographies: A question of languages

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.
Abstract This intervention responds to the ‘Geography in the World’ series, addressing the question from two angles. Firstly, it shifts the focus from geography in the world to worlding geographies. Drawing on Deleuze and Guattari's concept of ‘becoming‐minority’, it encourages reflection on the current geography of knowledge production as a historical,

Adaptive power and virtual resistance cooperation control strategy of VSG-based GFM converters for grid transient stability enhancement

open access: yesGlobal Energy Interconnection
With the increasing penetration level of renewable energy sources (RES) interfaced with the grids by power electronic converters, the grid forming (GFM) control of converters is recognized as one of the promising solutions in dealing with challenges such
