Designing soft materials with interfacial instabilities in liquid films
Nature Communications, 2018 Interfacial instabilities can be damaging as they may lead to fabrication defects. Here the authors harness a fluid instability to their advantage to produce thin polymeric films with drop-shaped structures which have tailored geometrical properties.

Gravity-driven thin film flow of an ellis fluid [PDF]
Journal of Non-Newtonian Fluid Mechanics, 2013 The thin film lubrication approximation has been studied extensively for moving contact lines of Newtonian fluids. However, many industrial and biological applications of the thin film equation involve shear-thinning fluids, which often also exhibit a Newtonian plateau at low shear. This study presents new numerical simulations of the three-dimensional

On the channel flow of yield stress fluids with an internal microstructure
AIP Advances, 2023 Thin films consisting of polymer solutions are typically produced through a combination of extrusion and shearing processes, where the anisotropic, non-Newtonian solution is deformed and subjected to thermal treatment.

Some Aspects Concerning Titanium Coverage with Hydroxyapatite [PDF]
Archives of Metallurgy and Materials, 2022 Generally, the metallic implants do not exhibit any bio-integration properties in contact with bone tissues. To improve the interfacial properties of metallic implants in contact with bone, the coatings with thin biocompatible films are used. Two methods

In-situ Characterization of Drying Particulate Coatings
KONA Powder and Particle Journal, 2014 Film thin drying is a process to create functional interfaces in solidifying liquids, rather than to separate volatile components from solutions or suspensions.

A Brief Discussion Regarding Types of Cavitation in Squeeze Film Dampers and Cavitation Effects [PDF]
INCAS Bulletin, 2017 Squeeze film dampers (SFD) are probably the most used shaft control devices in aircraft jet engines; SFDs consist in oil films, elastic elements and various antirotational devices that tune the stiffness and damping of the shafts’ supports and ...

A multi-feature predicting model of crown evolution involving material properties
AIP Advances, 2022 We propose a new model for the crown evolution after a single drop impacts on a thin film. In contrast with the existing models that mainly focus on the status of well-developed crown or the bottom radius evolution, multiple features are provided in our ...
