How to blow big bubbles?

Together will colleagues from Nottingham Trent University we studied how to blow the biggest bubbles. The key is going as slow as you can, but no slower! The work has just been published in Soft (...)

Publication: Real time ultrasound assessment of contact progress between food gels and tongue mimicking surfaces during a compression

Publication: Real time ultrasound assessment of contact progress between food gels and tongue mimicking surfaces during a compression

An in vitro study was conducted to further explore the potential of an emerging ultrasound method for monitoring in real time the progress of the contact between gels with different physical (...)

Publication: Viscoelasticity-Induced Onset of Slip at the Wall for Polymer Fluids

Publication: Viscoelasticity-Induced Onset of Slip at the Wall for Polymer Fluids

The progressive onset of slip at the wall, which corresponds to a slip length increasing with the solicitation time before reaching a plateau, has been investigated for model viscoelastic polymer (...)

Publication: Stability of big surface bubbles: impact of evaporation and bubble size

In this article, we explore the lifetime and thinning dynamics of centimetric surface bubbles. We study the impact of the bubble size as well as that of the atmospheric humidity through a careful (...)

Drop freezing: fine detection of contaminants by measuring the tip angle

In this Letter, we show that the shape of a freezing drop of water can be sensitive to the presence of impurities. We measure the tip angle of water drops frozen on a cold plate. The fine changes (...)

Roughness-induced friction in liquid foams

Complex liquids flow is known to be drastically affected by the roughness condition at the interfaces. We combined stresses measurements and observations of the flow during the motion of (...)

Colloidal gelation, a means to study elastocapillarity effects in foam

We explore the evolution of the mechanical properties of a coarsening foam containing colloidal particles that undergo a sol–gel transition in the continuous phase. This enables us to investigate (...)

Nanorheology with a Conventional Rheometer: Probing the Interfacial Properties in Compatibilized Multinanolayer Polymer Films

Nanorheology with a Conventional Rheometer: Probing the Interfacial Properties in Compatibilized Multinanolayer Polymer Films

A new publication in ACS Macro Letter.
Measuring the viscoelastic behavior of polymers in the vicinity of a surface or under confinement is an experimental challenge. Simple rheological tests of (...)
