Non-equilibrium Gas-phase Nitrogenation
Non-equi l ibr ium ni trogenat ion of transition-metal rich rare-earth intermetallics can be used to increase the nitrogen content beyond its equilibrium concentration. For example, nitrogenation of S m 2 F e l 7 using ammonia yields volume expansions up to 8.3 vol %, which correspond to a composition S m 2 F e 1 7 N x with x = 4. This effect is related to catalytic action at the metal surface ...
متن کاملNon-equilibrium phase transitions
These lecture notes give a basic introduction to the physics of phase transitions under non-equilibrium conditions. The notes start with a general introduction to non-equilibrium statistical mechanics followed by four parts. The first one discusses the universality class of directed percolation, which plays a similar role as the Ising model in equilibrium statistical physics. The second one giv...
متن کاملThermostatistics of a Relativistic Gas: Equilibrium and Non-equilibrium Properties
The introduction of models to simulate dynamics of relativistic gaseous systems is among the latest efforts made in the recent decades to investigate the relativistic generalizations of statistical thermodynamics. Relativistic thermodynamics was born in the early 20th century to investigate the consequences of Einstien’s special relativity on thermodynamic systems. A simple and important questi...
متن کاملBoundary-Induced Phase Transitions in Equilibrium and Non-Equilibrium Systems
Boundary conditions may change the phase diagram of non-equilibrium statistical systems like the one-dimensional asymmetric simple exclusion process with and without particle number conservation. Using the quantum Hamiltonian approach, the model is mapped onto an XXZ quantum chain and solved using the Bethe ansatz. This system is related to a two-dimensional vertex model in thermal equilibrium....
متن کاملNon-Equilibrium Isomer Distribution of the Gas-Phase Photoactive Yellow Protein Chromophore.
The conjugate base of para-coumaric acid, which can be conveniently generated in the gas phase by electrospray ionization (ESI), is a commonly used model system for the chromophore of the photoactive yellow protein. Here we report its gas-phase IR spectrum, which shows that the anion easily adopts a carboxylate structure lying 60 kJ/mol higher in energy than the global minimum phenoxide structu...
