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

Small, 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

Meteorological 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.

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

Earth 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,
