Patterned deposition at moving contact lines

U Thiele - Advances in colloid and interface science, 2014 - Elsevier
When a simple or complex liquid recedes from a smooth solid substrate it often leaves a
homogeneous or structured deposit behind. In the case of a receding non-volatile pure …

Recent advances in and future challenges for mesoscopic hydrodynamic modelling of complex wetting

U Thiele - Colloids and Surfaces A: Physicochemical and …, 2018 - Elsevier
We highlight some recent developments that widen the scope and reach of mesoscopic thin-
film (or long-wave) hydrodynamic models employed to describe the dynamics of thin films …

Tractionless self-propulsion of active drops

A Loisy, J Eggers, TB Liverpool - Physical review letters, 2019 - APS
We report on a new mode of self-propulsion exhibited by compact drops of active liquids on
a substrate which, remarkably, is tractionless, ie, which imparts no mechanical stress locally …

Thin-film modeling of resting and moving active droplets

S Trinschek, F Stegemerten, K John, U Thiele - Physical Review E, 2020 - APS
We propose a generic model for thin films and shallow drops of a polar active liquid that
have a free surface and are in contact with a solid substrate. The model couples evolution …

How many ways a cell can move: the modes of self-propulsion of an active drop

A Loisy, J Eggers, TB Liverpool - Soft Matter, 2020 - pubs.rsc.org
Numerous physical models have been proposed to explain how cell motility emerges from
internal activity, mostly focused on how crawling motion arises from internal processes. Here …

Phase transition and dewetting of a 5CB liquid crystal thin film on a topographically patterned substrate

P Dhara, R Mukherjee - RSC advances, 2019 - pubs.rsc.org
We report thermally induced nematic to isotropic (N–I) phase transition as well as dewetting
of 5CB Liquid Crystal (LC) thin films coated on flat and topographically patterned substrates …

Symmetry-breaking, motion and bistability of active drops through polarization-surface coupling

F Stegemerten, K John, U Thiele - Soft Matter, 2022 - pubs.rsc.org
Cell crawling crucially depends on the collective dynamics of the acto-myosin cytoskeleton.
However, it remains an open question to what extent cell polarization and persistent motion …

A theoretical investigation of weak-anchoring effects in a thin two-dimensional pinned static
ridge of nematic liquid crystal resting on a flat solid substrate in an atmosphere of passive …

Young and Young–Laplace equations for a static ridge of nematic liquid crystal, and transitions between equilibrium states

JRL Cousins, BR Duffy, SK Wilson… - Proceedings of the …, 2022 - royalsocietypublishing.org

a nematic liquid crystal, a solid substrate and a passive gas that include nematic–substrate …

Computing dynamics of thin films via large scale GPU-based simulations

MAYH Lam, LJ Cummings, L Kondic - Journal of Computational Physics: X, 2019 - Elsevier
