Molecular Desorption by a Moving Contact Line
Physical Review Letters, 2021 The interaction of the contact line with topographical or chemical defects at the nanometer scale sets the macroscopic wetting properties of a liquid on a solid substrate. Based on specific atomic force microscopy (AFM) experiments, we demonstrate that molecules physically sorbed on a surface are removed by a dynamic contact line.

A miniature non-circular line gear with pure-rolling contact
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021 The design of pure-rolling gear has always been a subject of intense research, because in some working conditions, such as dry friction, pure-rolling gear has higher transmission efficiency and less possibility of transmission failure. Non-circular gears

Critical Dynamics of Contact Line Depinning [PDF]
MRS Proceedings, 1994 ABSTRACTThe depinning of a contact line is studied as a dynamical critical phenomenon by a functional renormalization group technique. In D = 2 - ∈ “line” dimensions, the roughness exponent is ζ = ∈/3 to all orders in perturbation theory. Thus, ζ = 1/3 for the contact line, equal to the Imry-Ma estimate for equilibrium roughness. The dynamical exponent

Is contact-line mobility a material parameter?
npj Microgravity, 2022 Dynamic wetting phenomena are typically described by a constitutive law relating the dynamic contact angle θ to contact-line velocity U C L . The so-called Davis–Hocking model is noteworthy for its simplicity and relates θ to U C L through a contact-line

Dissipation in dynamics of a moving contact line [PDF]
Physical Review E, 2001 The dynamics of the deformations of a moving contact line is studied assuming two different dissipation mechanisms. It is shown that the characteristic relaxation time for a deformation of wavelength $2π/|k|$ of a contact line moving with velocity $v$ is given as $τ^{-1}(k)=c(v) |k|$.

Catenoid Stability with a Free Contact Line [PDF]
SIAM Journal on Applied Mathematics, 2015 Contact-drop dispensing is central to many small-scale applications, such as direct-scanning probe lithography and micromachined fountain-pen techniques. Accurate and controllable dispensing required for nanometer-resolved surface patterning hinges on the stability and breakup of liquid bridges.

Transfer Durability of Line-Patterned Replica Mold Made of High-Hardness UV-Curable Resin
Nanomaterials, 2020 Ultraviolet nanoimprint lithography (UV-NIL) requires high durability of the mold for the mass production of nanostructures. To evaluate the durability of a line-patterned replica mold made of high-hardness UV curable resin, repetitive transfer and ...
