Das reale Gas

2015
Das Modell des idealen Gases ist, wie der Name bereits sagt, ein idealisiertes Modell. Wann gilt dieses Modell? Wie gelangt man von der erfolgreichen Theorie idealer Gase zu einer Beschreibung realer Gase? In diesem Kapitel wird aufgezeigt, wie sich eine Theorie erweitern und verfeinern lasst. Ein Schwerpunkt der Thematik ist die van der Waals-Theorie,

Designing Real Nanotube-Based Gas Sensors

Physical Review Letters, 2008
Using a combination of density functional theory and recursive Green's functions techniques, we present a full description of a large scale sensor, accounting for disorder and different coverages. Here, we use this method to demonstrate the functionality of nitrogen-rich carbon nanotubes as ammonia sensors as an example.

Real gas effects in non-equilibrium gas dynamics

Physica A: Statistical Mechanics and its Applications, 1978
Abstract Using the linearized system of equations due to de Groot and Mazur governing the acoustic non-equilibrium phenomena in a viscous, heat-conducting gas, we have in this paper given an exhaustive treatment of the problem of wave propagation. More specifically, the normal mode analysis brings out a qualitative and quantitative account of the ...
