Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery
Wind Energy, Volume 29, Issue 3, March 2026.ABSTRACT When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices. This structure occurs to be more stable in low ambient turbulence and low tip speed ratio

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels
Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention
Advanced Science, Volume 13, Issue 8, 9 February 2026.A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior
Advanced Physics Research, Volume 5, Issue 2, February 2026.Diel vertical migration hides an unexpected twist: Phytoplankton quietly engineer their local pH landscape, splitting into behaviorally distinct sub‐groups which stay separated even in identical conditions. Circadian pH changes, occuring over the course of a day, reshape their gravitactic behavior and physiological functions in ways scientists have ...

A Versatile Setup for Determining Hydrogen and Oxygen Crossover of Electrolyzer Membranes and MEAs
Chemie Ingenieur Technik, Volume 98, Issue 1-2, Page 18-26, February 2026.Hydrogen and oxygen crossover in PEM electrolyzers affects safety, efficiency and gas purity. We present an experimental setup to quantify crossover through membranes and polymers. It allows in‐situ tests on full cells with MEAs and measures gas permeation in wet or dry ionomers and other polymers.
