Hierarchical Surface Instability in Polymer Films
Langmuir, 2023This study demonstrates hierarchical instabilities in thin films. The hierarchical instabilities display three morphological characteristics: (1) windmill-like patterns at the macroscale, (2) Bénard cells and striations at the microscale, and (3) holes at the mesoscale.

Chemical Instabilities. II. Chemical Surface Reactions and Hydrodynamic Instability
The Physics of Fluids, 1971A linear stability analysis of the hydrodynamics of the isothermal two-component reactive fluid (A2, A), confined between two infinite parallel plates, and involved in the surface catalyzed reaction (A2⇋2A) is performed. The existence of solutions to the eigenvalue problem governing the state of marginal instability corresponding to pure convection is ...

Instability of the ideal tungsten (001) surface
Physical Review Letters, 1986The energetics of reconstruction models of the ideal W(001) and Ta(001) surfaces are studied by the general-potential linearized augmented plane-wave method. The ideal W(001) surface is found to be very unstable to the low-temperature Debe and King c(2\ifmmode\times\else\texttimes\fi{}2) structure, gaining an energy of about 1200 K upon reconstruction.

Instability of Surface and Internal Waves
1976Publisher Summary This chapter investigates the instability of surface waves propagating in water of uniform depth, finite or infinite, by a variational method by considering two side-band wave numbers and frequencies in addition to the wave number and frequency of the primary wave train.

Surface Instabilities of Ferrofluids
2008We report on recent progress in understanding the formation of surface protuberances on a planar layer of ferrofluid in a magnetic field oriented normally to the surface. This normal field or Rosensweig instability can be tackled by a linear and a nonlinear description.

Groove instabilities in surface growth with diffusion
Physical Review E, 1993The existence of a grooved phase in linear and nonlinear models of surface growth with horizontal diffusion is studied in d=2 and 3 dimensions. We show that the presence of a macroscopic groove, i.e., an instability towards the creation of large slopes and the existence of a diverging persistence length in the steady state, does not require higher ...

Creasing instability of surface-attached hydrogels
Soft Matter, 2008The unidirectional expansion of a thin surface-attached polymer gel upon swelling by solvent generates a biaxial compressive stress within the gel. For sufficiently large stresses, a mechanical instability can occur in which the free surface locally buckles and folds against itself to form creases.

Bifurcating Instability of the Free Surface of a Ferrofluid
SIAM Journal on Mathematical Analysis, 1983The authors have studied the bifurcating instability of the free surface of a slab of ferrofluid bounded below by a fixed boundary and above by a vacuum. The slab of fluid is subjected to a strong magnetic field in the vertical direction. The relevant equations of the problem are derived. The free surface does not allow a natural Banach space structure
