Multifunctional Superwetting Sea‐Urchin‐Mimetic Nanosheet‐Based Interface for Remote Oil‐Water Separation

open access: yesSmall, EarlyView.
A fluorine‐free, FBC–rGO coating‐based robust superhydrophobic/superoleophilic sorbent (WCA >154°), enabling rapid, selective oil uptake and efficient oil/water separation. Integrated into a dolphin‐inspired Wi‐Fi mini‐bot with onboard pumping and storage, the platform enables remote, contactless, on‐site oil recovery from hazardous spill zones ...

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

open access: yesSmall Structures, EarlyView.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...
