Analysis of Dynamic Wetting and Dewetting on a Hydrophobic Surface Using Molecular Kinetic Theory

Tribology Online
The dynamic wetting and dewetting of a water droplet on a hydrophobic solid surface with an equilibrium contact angle of approximately 100° was investigated using molecular kinetic (MK) theory to model the extension–contraction experiment and numerically

Langevin dynamics of spreading and wetting

Physical Review Letters, 1990
Summary: We propose a solid-on-solid-model description of the dynamics of wetting, using Langevin equations. The Gaussian version, appropriate to partial wetting, is solved exactly. The general version is solved using local equilibrium and scaling arguments.

Study on the Navier boundary condition for flows with a moving contact line by means of molecular dynamics simulation

Nihon Kikai Gakkai ronbunshu, 2015
While the Navier boundary condition, which claims the proportionality between fluid slip velocity and wall shear stress (Qian et al., 2003, Bocquet and Barrat, 2007), was established by Thompson and Troian (1997) for a single-phase Newtonian fluid ...

Effect of roughness on wettability and floatability: Based on wetting film drainage between bubbles and solid surfaces

International Journal of Mining Science and Technology, 2022
Wetting film thinning measurement was introduced to clarify the wettability and floatability of solid surfaces with varying roughness. The wettability was quantified using the contact angle measurement combined with the dynamic force microbalance test ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

The role of the microscale contact line dynamics in the wetting behaviour of complex fluids

Archives of Mechanics, 2015
The microscale morphology of the liquid-substrate contact line is studied experimentally in two well-known examples of dynamic wetting with complex fluids (namely, drop impact of dilute polymer solutions and spreading of superspreader surfactant ...

Wetting of Cu-SiC Composite Material Modified by Nanosecond Laser Radiation and Liquid Spreading over It

Applied Sciences, 2023
In the framework of this work, the surface properties of Cu-SiC composite material were studied when spreading micro- and nanoliter liquids. The Cu-SiC samples with a SiC content of 5 to 20 wt.% were fabricated by spark plasma sintering at temperatures ...
