Emergent Motility of Self‐Organized Particle‐Giant Unilamellar Vesicle Assembly

Advanced Materials, EarlyView.
Giant unilamellar vesicles (GUVs), when combined with silica particles under alternating electric fields, spontaneously self‐assemble into motile structures. Asymmetric particle decoration induces fluid flows that propel the assemblies, enabling persistent motion and reversible control.

Size‐Dependent Contact Angles of Microscopic Droplets on Ultra‐Smooth Silanized Surfaces Probed by Atomic Force Microscopy

Advanced Materials Interfaces, EarlyView.
Wetting is vital in many technologies, but remains hard to predict due to complex phase interactions. Young's law predicts macroscale wetting on ideal surfaces, while line tension theory is limited to nanoscale droplets. Here, using AFM, the scale gap is bridged by focusing on microscopic droplets and predicting their contact angle on real surfaces ...

2-D Modeling of hyperconcentrated fluid flow in curvilinear coordinates: dam break study

Applied Water Science
The hyperconcentrated fluid flow occurs as a result of heavy rainfall, during which a large amount of sediments from the upstream basin is washed away and suddenly increases the flow concentration of the alluvial channels.
