Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

open access: yesSmall, Volume 22, Issue 58, 16 October 2026.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Nanosecond, Nanometer Movies of MEMS/NEMS Dynamics in a Standard SEM Using Time‐Tagged Secondary Electrons

open access: yesSmall Methods, Volume 10, Issue 19, 7 October 2026.
For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

Accelerated Surface Reconstruction in Double Perovskites: Enhancing Oxygen Evolution Reaction Activity Through Fe‐Doping

open access: yesSusMat, Volume 6, Issue 5, October 2026.
A novel double perovskite BaSrNi0.9Fe0.1WO6 (BSNFW) is developed with enhanced oxygen evolution reaction (OER) activity owing to synergistic Ni‒Fe interactions occurring through bridging O species. This drives an accelerated surface reconstruction that equilibrates an oxidized and highly active surface configuration in situ, without the need for ...

Uncovering Responses of the Amazon Fluvial Lake System to the 2024 Drought by Fusing SWOT and Sentinel‐1 Observations

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract The 2024 Amazonian drought presented an unprecedented hydroclimatic anomaly. While prior research focused on atmospheric drivers and river impacts, the response of Amazon fluvial lake system (AFLs) has lacked large‐scale quantification. This study investigates the hydrological response of 838 fluvial lakes to the 2024 drought by integrating ...
