Atomic-Scale Insights into Surface Instability in Halide Perovskites.
Nano letters (Print)The pathway of surface structure evolution plays a vital role in determining the stability of the halide perovskites. Understanding the mechanism of surface instability and how external stimuli interact with the surface is essential for developing ...

Colloid Journal, 2008
This review is devoted to the comprehensive description of instabilities of different types that appear at the interface due to various physical reasons. The conditions and mechanisms of the disintegration of jets and droplets under the action of surface forces, beginning with the classical Rayleigh disintegration and ending with the current notions of

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 ...

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.

Sex-Specific Effects of Surface Instability on Drop Jump and Landing Biomechanics
International Journal of Sports Medicine, 2014This study investigated sex-specific effects of surface instability on kinetics and lower extremity kinematics during drop jumping and landing. Ground reaction forces as well as knee valgus and flexion angles were tested in 14 males (age: 23±2 years) and

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.

Instability in surface growth with diffusion
Physical Review Letters, 1992A model for surface growth with some of the features of molecular-beam epitaxy is proposed and investigated. Particles are deposited randomly on a one-dimensional substrate and the surface relaxes through diffusion processes, which obey detailed balance. The model undergoes a phase transition from a rough phase to a grooved phase.

Topological instability along filamented invariant surfaces
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2003In dynamical systems with a zero Lyapunov exponent, weak mixing can be governed by a specific topological structure of some surfaces that are invariant with respect to particle dynamics. In particular, when the genus of the invariant surfaces is more than one, they may have weak mixing and the corresponding fractional kinetics.

Cracklike surface instabilities in stressed solids
Physical Review Letters, 1993The surface of an elastically stressed solid is shown to undergo an instability in which deep, cracklike grooves form by surface diffusion. These grooves sharpen and accelerate as they deepen. The resultant morphology is in excellent agreement with recent experimental observation in several disparate materials systems.
