Polymers at interfaces and the interactions in colloidal dispersions

A Vrij - Pure and Applied Chemistry, 1976 - degruyter.com
Solutions of different polymers in the same solvent are incompatible as a rule and show
phase separation when they are mixed. H incompatibility is also to be observed in systems …

Capturing self-propelled particles in a moving microwedge

A Kaiser, K Popowa, HH Wensink, H Löwen - Physical Review E—Statistical …, 2013 - APS
Catching fish with a fishing net is typically done either by dragging a fishing net through
quiescent water or by placing a stationary basket trap into a stream. We transfer these …

Geometry-induced capillary emptying

C Rascón, AO Parry, DGAL Aarts - … of the National Academy of Sciences, 2016 - pnas.org
When a capillary is half-filled with liquid and turned to the horizontal, the liquid may flow out
of the capillary or remain in it. For lack of a better criterion, the standard assumption is that …

Continuous and discontinuous dynamic unbinding transitions in drawn film flow

M Galvagno, D Tseluiko, H Lopez, U Thiele - Physical review letters, 2014 - APS
When a plate is withdrawn from a liquid bath a coating layer is deposited whose thickness
and homogeneity depend on the velocity and the wetting properties of the plate. Using a …

Multistability of a long droplet in a capillary tube under transverse body force

D Tan, X Zhou - Journal of Fluid Mechanics, 2024 - cambridge.org
Bistable states for a sufficiently large amount of liquid can appear in an eccentric capillary
due to the eccentricity effect under zero gravity (J. Fluid Mech, vol. 863, 2019, pp. 364–385) …

Spinodal decomposition of a confined colloid-polymer system

EAG Jamie, RPA Dullens, D Aarts - The Journal of chemical physics, 2012 - pubs.aip.org
We study the demixing via spinodal decomposition of a fluid-fluid phase separating colloid-
polymer mixture confined between parallel plates, where one of the phases completely wets …

Edge contact angle, capillary condensation, and meniscus depinning

A Malijevský, AO Parry - Physical Review Letters, 2021 - APS
We study the phase equilibria of a fluid confined in an open capillary slit formed when a wall
of finite length H is brought a distance L away from a second macroscopic surface. This …

Viscous fingering at ultralow interfacial tension

SA Setu, I Zacharoudiou, GJ Davies, D Bartolo… - Soft Matter, 2013 - pubs.rsc.org
We experimentally study the viscous fingering instability in a fluid–fluid phase separated
colloid–polymer mixture by means of laser scanning confocal microscopy and microfluidics …

Microscopic aspects of wetting using classical density functional theory

P Yatsyshin, MA Durán-Olivencia… - Journal of Physics …, 2018 - iopscience.iop.org
Wetting is a rather efficient mechanism for nucleation of a phase (typically liquid) on the
interface between two other phases (typically solid and gas). In many experimentally …

Complete prewetting

P Yatsyshin, AO Parry… - Journal of Physics …, 2016 - iopscience.iop.org
We study continuous interfacial transitions, analagous to two-dimensional complete wetting,
associated with the first-order prewetting line, which can occur on steps, patterned walls …
