DOI: 10.1021/acs.langmuir.4c04939
Abstract: This study investigates the fingering instability that forms during the stretching of capillary suspensions with and without added nanoparticles. The dewetting process is observed using a transparent lifted Hele-Shaw cell. The liquid bridge is stretched… read more here.

DOI: 10.1103/physrevfluids.3.124004
Abstract: Weakly nonlinear analysis is used to study fingering instabilities in radially tapered (converging and diverging) Hele-Shaw cells. It is found that changes in the capillary number modify the interface instability behavior and the finger shapes… read more here.

DOI: 10.1103/physrevlett.122.088104
Abstract: During the spreading of epithelial tissues, the advancing tissue front often develops fingerlike protrusions. Their resemblance to traditional viscous fingering patterns in driven fluids suggests that epithelial fingers could arise from an interfacial instability. However,… read more here.
