Enhancing microalgal cell wall permeability by microbubble streaming flow
Angelo Pommella, Irina Harun, Klaus Hellgardt +1
We demonstrate that the permeability of the cell wall of microalga can be enhanced in controlled microstreaming flow conditions using single bubbles adher…
Enhanced microscopic dynamics in mucus gels under a mechanical load in the linear viscoelastic regime
Domenico Larobina, Angelo Pommella, Adrian-Marie Philippe +2
Mucus is a biological gel covering the surface of several tissues and insuring key biological functions, including as a protective barrier against dehydration, pathogens penetratio…
Role of normal stress in the creep dynamics and failure of a biopolymer gel
Angelo Pommella, Luca Cipelletti, Laurence Ramos
We investigate the delayed rupture of biopolymer gels under a constant shear load by simultaneous dynamic light scattering and rheology measurements. We unveil the crucial role of…
A novel setup coupling space-resolved dynamic light scattering and rheometetry unveils the heterogeneous flow field and non-affine dynamics in startup shear of a gel
A. Pommella, A. -M. Philippe, T. Phou +2
We present a new light scattering setup coupled to a commercial rheometer operated in the plate-plate geometry. The apparatus allows the microscopic dynamics to be measured, discri…
Dynamic behaviour of Multilamellar Vesicles under Poiseuille flow
Angelo Pommella, Dario Donnarumma, Sergio Caserta +1
Surfactant solutions exhibit multilamellar surfactant vesicles (MLVs) under flow conditions and in concentration ranges which are found in a large number of industrial applications…
High-frequency capillary waves excited by oscillating microbubbles
Angelo Pommella, Jeanne Lantz, Vincent Poulichet +1
This fluid dynamics video shows high-frequency capillary waves excited by the volumetric oscillations of microbubbles near a free surface. The frequency of the capillary waves is c…
