Study on compsiiton stability of gas mixture through leak arteafact

open access: yesMeasurement: Sensors, 2021
Leak test by sniffing method is widely used and the leak rate is traceable to the SI unit via a leak detector and a leak artefact. Recently, a gas mixture, for example a gas mixture of 5% hydrogen and 95% nitrogen, is used as a tracer gas. In case of the

Thermal Diffusion Factor in Gas Mixture-Dufour Effect (I) [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1991
The thermal diffusion factor, aT, for a binary gas mixture is calculated on the basis of nonequilibrium thermodynamics. A new formula for aT is derived and this factor is given for several paris of gases according to this formula.

An exactly solvable quantum four-body problem associated with the symmetries of an octacube

open access: yesNew Journal of Physics, 2015
In this article, we show that eigenenergies and eigenstates of a system consisting of four one-dimensional hard-core particles with masses 6 m , 2 m , m , and 3 m in a hard-wall box can be found exactly using Bethe Ansatz.
