Topography‐Free Dual‐Lubricant Patterned Slippery Surfaces for Programmable Droplet Control and High‐Performance Water Harvesting

open access: yesSmall, Volume 22, Issue 19, 1 April 2026.
A patterned dual‐lubricant SLIPS creates interfacial energy asymmetry, guiding droplet migration without external actuation. Condensed droplets formed on the fluorinated‐oil‐infused regions migrate to the silicone‐oil‐infused domains, where rapid growth and coalescence occur.

Numerical Simulation of Flow Induced by Plasma Synthetic Jet Actuator

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2004
Flow induced by plasma synthetic jet actuator (PSJA) is investigated using computational fluid dynamics. PSJA is a flow control device and induces flow using electrohydrodinamic (EHD) effect around electrodes exerted AC voltage. Its mechanism is not well known, but it is said that paraelectric force proportioned to gradient of electric energy density ...

Data‐Driven Exploration of Tropical Cyclone's Controllability

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Although the chaotic nature of the atmosphere may enable efficient control of tropical cyclones (TCs) via small‐scale perturbations, few studies have proposed data‐driven optimization methods to identify such perturbations. Here, we apply the recently proposed Ensemble Kalman Control (EnKC) to a TC simulation.
