Surface tension gradients are at the origin of the self-motion and deformation of millimeter-
sized floating objects. For (quasi-) non-deformable systems, like solids and gels, the motion …

Understanding the fundamentals of surface transport on thin viscous films has important
application in pulmonary drug delivery. The human lung contains a large-area interface …

We consider the flow dynamics of a thin evaporating droplet in the presence of an insoluble
surfactant and noninteracting particles in the bulk. On the basis of lubrication theory, we …

Gel layers bound to a rigid substrate are used in cell culture to control differentiation and
migration and to lower the friction and tailor the wetting of solids. Their thickness, often …

A surfactant-covered droplet on a solid surface subject to a three-dimensional shear flow is
studied using a lattice-Boltzmann and finite-difference hybrid method, which allows for the …

The interplay of interfacial tensions on droplets results in a range of self‐powered motions
that mimic those of living systems and serve as a tunable model to understand their complex …

The complicated dynamics of the contact line of a moving droplet on a solid substrate often
hamper the efficient modeling of microfluidic systems. In particular, the selection of the …

Studies on the evaporation of multicomponent droplets have revealed complex and
important physical mechanisms, induced by preferential phase change or mediated by …

Hypothesis The question of why aqueous solutions of some surfactants demonstrate a rapid
spreading (superspreading) over hydrophobic solid substrates, while solutions of other …

The number of individuals suffering from diseases of the central nervous system (CNS) is
growing with an aging population. While candidate drugs for many of these diseases are …
