Despite its importance in many industrial, geological and biological processes, the
mechanism of crystallization from supersaturated solutions remains a matter of debate …

Controlling the growth morphology of fluid instabilities is challenging because of their self-
amplified and nonlinear growth. The viscous fingering instability, which arises when a less …

Swarming is a collective flagella-dependent movement of bacteria across a surface that is
observed across many species of bacteria. Due to the prevalence and diversity of this …

A hydrostatically stressed soft elastic film circumvents the imposed constraint by undergoing
a morphological instability, the wavelength of which is dictated by the minimization of the …

The invasion of one fluid into another of higher viscosity in a quasi-two dimensional
geometry typically produces complex fingering patterns. Because interfacial tension …

Thin streams of liquid commonly break up into characteristic droplet patterns owing to the
surface-tension-driven Plateau–Rayleigh instability,,. Very similar patterns are observed …

Pattern-forming processes in simple fluids and suspensions have been studied extensively,
and the basic displacement structures, similar to viscous fingers and fractals in capillary …

Conventional viscous fingering flow in radial Hele-Shaw cells employs a constant injection
rate, resulting in the emergence of branched interfacial shapes. The search for mechanisms …

Many species of bacteria can spread over a moist surface via a particular form of collective
motion known as" surface swarming". This form of motility is typically studied by inoculating …

We study the displacement of immiscible fluids in deformable, noncohesive granular media.
Experimentally, we inject air into a thin bed of water-saturated glass beads and observe the …
