Co-nonsolvency of PNiPAM at the transition between solvation mechanisms
Irmgard Bischofberger, Davide C. E. Calzolari, Veronique Trappe
We investigate the co-nonsolvency of poly-N-isopropyl acrylamide (PNiPAM) in different water-alcohol mixtures and show that this phenomenon is due to two distinct solvation contrib…
Fingering versus stability in the limit of zero interfacial tension
Irmgard Bischofberger, Radha Ramachandran, Sidney R. Nagel
The invasion of one fluid into another of higher viscosity in a quasi-two dimensional geometry typically produces complex fingering patterns. Because interfacial tension suppresses…
An island of stability in a sea of fingers: emergent large-scale features of the viscous flow instability
Irmgard Bischofberger, Radha Ramachandran, Sidney R. Nagel
The displacement of a more viscous fluid by a less viscous one in a quasi-two dimensional geometry leads to the formation of complex fingering patterns. This fingering has been cha…
