How molecular effects affect solutal Marangoni convection
Petter Johansson, Guillaume Galliéro, Dominique Legendre
Interfacial tension gradients drive flow along liquid-liquid interfaces in a process known as the Marangoni effect. Such gradients can be caused by surfactants, which has been exte…

Steady moving contact line of water over a no-slip substrate
Uǧis Lācis, Petter Johansson, Tomas Fullana +4
The movement of the triple contact line plays a crucial role in many applications such as ink-jet printing, liquid coating and drainage (imbibition) in porous media. To design accu…

Electrowetting diminishes contact line friction in molecular wetting
Petter Johansson, Berk Hess
We use large-scale molecular dynamics to study dynamics at the three-phase contact line in electrowetting of water and electrolytes on no-slip substrates. Under the applied electro…
