Modelling Pattern Formation in Dip-Coating Experiments
TL;DR: In this article, the authors review selected mathematical models that describe the dynamics of pattern formation phenomena in dip-coating and Langmuir-Blodgett transfer experiments, where solutions or suspensions are transferred onto a substrate producing patterned deposit layers with structure length from hundreds of nanometres to tens of micrometres.
Origin of finite pulse trains: Homoclinic snaking in excitable media.
TL;DR: A new class of phenomena relevant to spatiotemporal dynamics of excitable media, particularly in chemical and biological systems with multiple activators and inhibitors is revealed, thereby blurring the traditional distinction between oscillatory and excitable systems.
Emergence of the bifurcation structure of a Langmuir-Blodgett transfer model
Michael H. Köpf,Uwe Thiele +1 more
TL;DR: In this paper, the bifurcation structure of a modified Cahn-Hilliard equation was explored for a system that may undergo a first order phase transition and is kept permanently out of equilibrium by a lateral driving.

Controlled nanochannel lattice formation utilizing prepatterned substrates.
TL;DR: The effect of periodically prepatterned substrates on this process of pattern formation leads to a time periodic forcing of the oscillatory behavior at the meniscus, and complex periodic patterns of predefined wavelength can be created.

Thin film dynamics with surfactant phase transition
TL;DR: In this article, a thin liquid film covered with an insoluble surfactant in the vicinity of a first-order phase transition is discussed, and two coupled equations are derived to describe the height profile of the film and its density.
