Nonequilibrium Period with Emergence of Marangoni Circulations in Meniscus Splitting

open access: yesAdvanced Materials Interfaces, EarlyView.
The emergence and evolution of Marangoni convection in the meniscus splitting phenomenon are investigated. During the mass circulation of viscous fluids, the confluence and bifurcation of polymer dispersions beneath the evaporative interface lead to the inhomogeneous densification of the skin layer.

Centrifugation Theory Revisited: Understanding and Modeling the Centrifugation of 2D Nanosheets

open access: yesAdvanced Materials Interfaces, EarlyView.
Colloidal dispersions of nanomaterials are often size‐selected by centrifugation, for anisotropic particle shapes in trial and error. This paper describes the derivation of an equation of motion for 2D objects. The model is validated using different nanosheets produced from liquid phase exfoliation and can be used to predict the average nanosheet sizes

Effect of Electric Field on Growth Kinetics, Morphology and Wettability of Flame‐Deposited Carbon Nanoparticle Coatings

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel electric field‐assisted thermophoretic flame synthesis process enables rapid deposition of carbon nanoparticle films with tunable wettability. Applying a negative voltage during flame exposure accelerates growth, increases surface roughness, and alters morphology.

Scalable Conversion of Superhydrophobic Surfaces to Salvinia Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
This article reports a scalable method to convert superhydrophobic surfaces into Salvinia surfaces by selectively coating polydopamine on the top surfaces of microstructures. The success is enabled by overcoming a previously unrecognized barrier unique to polydopamine coating on superhydrophobic surfaces.
