The Onsager principle is a variational principle proposed by Lars Onsager in 1931 in his
celebrated paper on the reciprocal relation in non-equilibrium thermodynamics. The …

Room-temperature ionic liquids (RTILs) are intriguing fluids that have drawn much attention
in applications ranging from tribology and catalysis to energy storage. With strong …

Recent experiments (Guan et al., Phys. Rev. Lett., vol. 116, issue 6, 2016a, p. 066102; Guan
et al., Phys. Rev. E, vol. 94, issue 4, 2016b, p. 042802) showed many interesting …

A dynamic wetting problem is studied for a moving thin fiber inserted in fluid and with a
chemically inhomogeneous surface. A reduced model is derived for contact angle hysteresis …

We report a systematic experimental study of the mean temperature profile $\theta (\delta z)
$ and temperature variance profile $\eta (\delta z) $ across a stable and immiscible liquid …

We study theoretically the self-propulsion dynamics of a small droplet on general curved
surfaces by a variational approach. A new reduced model is derived based on careful …

During coating processes, dust deposition can lead to an uneven thickness in the resulting
film, posing significant problems in industrial processes. Our study explores the effects of …

By using the Onsager variational principle as an approximation tool, we develop a new
diffusion generated motion method for wetting problems. The method uses a signed …

We propose an adaptive threshold dynamics method for wetting problems in three space
dimensions. The method is based on solving a linear heat equation and a thresholding step …

Direct measurement and control of the dynamic wetting properties of a lipid-coated water–air
interface over a wide range of surface tension variations have many important applications …
