The influence of boundaries on gravity currents and thin films: drainage, confinement, convergence, and deformation effects

Z Zheng, HA Stone - Annual Review of Fluid Mechanics, 2022 - annualreviews.org
Thin film flows, whether driven by gravity, surface tension, or the relaxation of elastic
boundaries, occur in many natural and industrial processes. Applications span problems of …

Viscoplastic lines: printing a single filament of yield stress material on a surface

J van der Kolk, D Tieman, M Jalaal - Journal of Fluid Mechanics, 2023 - cambridge.org

Deformation and relaxation of viscous thin films under bouncing drops

S Lakshman, W Tewes, K Harth, JH Snoeijer… - Journal of Fluid …, 2021 - cambridge.org
Thin, viscous liquid films subjected to impact events can deform. Here we investigate free-
surface oil-film deformations that arise owing to the build up of air under the impacting and …

Softness of hydrated salt crystals under deliquescence

R Wijnhorst, M Demmenie, E Jambon-Puillet… - Nature …, 2023 - nature.com
Deliquescence is a first-order phase transition, happening when a salt absorbs water vapor.
This has a major impact on the stability of crystalline powders that are important for example …

Focused laser‐induced marangoni dewetting for patterning polymer thin films

JP Singer, SE Kooi, EL Thomas - Journal of Polymer Science …, 2016 - Wiley Online Library
Highly‐localized focused laser spike (FLaSk) heating of polymer thin films is a resist‐and

Spatiotemporal Mapping of Hole Nucleation and Growth during Block Copolymer Terracing with High-Speed Atomic Force Microscopy

JG Murphy, JG Raybin, GE Ansay, SJ Sibener - ACS nano, 2023 - ACS Publications
As a platform for investigating two-dimensional phase separation, we track the structural
evolution of block copolymer thin films during thermal annealing with environmentally …

Axisymmetric bare freestanding films of highly viscous liquids: Preparation and real-time investigation of capillary leveling

V Ferraro, MM Villone, V Tkachenko, L Miccio… - Journal of Colloid and …, 2021 - Elsevier

both the surface layers exposed to a different fluid phase, known as freestanding films, are …

Healing capillary films

Z Zheng, MA Fontelos, S Shin, MC Dallaston… - Journal of Fluid …, 2018 - cambridge.org
Consider the dynamics of a healing film driven by surface tension, that is, the inward
spreading process of a liquid film to fill a hole. The film is modelled using the lubrication (or …
