Dissipative structures catalysis

The question of the existence of spatially inhomogeneous stationary states (in terms of dissipative structures, DSs) in heterogeneous catalysis was first... 

Thereafter it has been stressed that the mechanism of diffusion driven instability is pertinent to the formation of dissipative structures in other fields electron-hole plasmas in semiconductors [12], gas discharge devices [13], semiconductor structures (p-n junction, p-i-n diodes) [14], heterogeneous catalysis [15], materials irradiated with energetic particles or light [16-18],... 

This ratio is vahd when the system operates close to thermodynamic equihbrium. It is, however, typical for heterogeneous catalysis to occur far from equihbrium in an open, nonlinear, dissipative, distributed, and multiparametric medium. Thus heterogeneous catalytic reactions exhibit diverse nonlinear phenomena the multiplicity of steady states (stable and unstable) hysteresis phenomena the ignition and extinction of the process critical phenomena phase transitions a high sensitivity of the process to changes in the parameters oscillations and wave phenomena chaotic regimes the formation of dissipative structures and seh organization phenomena.
