Total internal reflection microscopy: A powerful tool for exploring interactions and dynamics near interfaces

J Wu, W Liu, T Ngai - Soft Matter, 2023 - pubs.rsc.org
The occurrence of many micro/macrophenomena is closely related to interactions and
dynamics near interfaces. Hence, developing powerful tools for characterizing near-interface …

Bubble ring entrapment during a water drop impact on viscous oil films

L Luo, YS Tian, EQ Li - Physics of Fluids, 2024 - pubs.aip.org
Air entrapment during the drop impact on a liquid surface is crucial to the ocean–
atmosphere mass transfer process. Herein, we report a new mechanism of air entrapment …

On the bubble trapped underneath a droplet impacting a moving hydrophilic surface: From perfect slip to no slip

J Cheng, J Hao, Y Li, JM Floryan - Physics of Fluids, 2023 - pubs.aip.org
Much experimental evidence supports the commonly held assertion that fluid does not slip
along a solid surface. Here, we demonstrate circumstances in which slip occurs. This …

How does an emulsion drop's viscosity influence its impact on various meshes?

SK Dutta, DK Mandal - Physics of Fluids, 2024 - pubs.aip.org
The impact of emulsion drops on a mesh is studied. These drops find applications in various
fields, eg, agricultural sprays, where the drop passes through a mesh for atomization. Both …

Dual nature of volatility on drop wetting dynamics of acetone–isopropanol mixtures on ultrathin smooth oil films

Z He, MA Upoma, MY Pack - Physics of Fluids, 2023 - pubs.aip.org
Volatile drop impacts are commonplace among various industrial and natural processes and
are most often studied under Leidenfrost conditions, where a vaporized film sustains the …
