Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

BMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Dynamics of cavitation bubbles in a liquid layer

Droplet, EarlyView.
The dynamics of cavitation bubbles within a liquid layer is studied experimentally. Due to the combined effect of the rigid wall and free surface, the bubbles exhibit a significant downward migration. The confinement effect of the rigid wall significantly affects the bubble's collapse morphology, leading to different post‐collapse phenomena of free ...

Numerical Prediction of Cavitation Erosion Intensity in Cavitating Flows around a Clark Y 11.7% Hydrofoil

Journal of Fluid Science and Technology, 2010
A numerical prediction method of cavitation erosion is proposed. In this method, the analysis of bubbles in cavitating flows is performed and the intensity of cavitation erosion is evaluated by the impact pressure induced by spherical bubble collapse. In

A New Parameter to Predict Cavitation Erosion

, 2001
In order to avoid or predict cavitation erosion, it is necessary to know resistance of materials against to cavitation impacts. The cavitation impacts, which are larger than certain threshold level, only affect cavitation erosion of materials.

Hydrogel Adhesives for Gastrointestinal Perforation: Design Principles and Applications

Exploration, EarlyView.
There are few reviews on hydrogel adhesives that comprehensively highlight the design principles, factors affecting adhesion, and applications for gastrointestinal (GI) perforation repair. This review outlines the mainstream design approaches of hydrogel adhesives via covalent and noncovalent molecular interactions, illustrating the underlying adhesive
