Off-lattice microscopic Monte Carlo modelling of molecular hydrogen formation on carbonaceous dust grains [PDF]

open access: goldMonthly Notices of the Royal Astronomical Society
ABSTRACT In this work, we present an off-lattice Monte Carlo model of accretion and migration of hydrogen atoms on a rough surface of carbon dust grain. The migration of physisorbed atoms by means of thermal diffusion and quantum tunnelling through barriers between the surface potential minima is considered.

Photoluminescence models in direct simulation Monte Carlo for molecular tagging techniques

open access: green, 2018
Molecular tagging techniques are promising tools for providing local measurements of pressure, temperature and velocity fields in rarefied gas flows. These techniques are based on the optical collection of photons emitted by a molecular tracer, such as acetone or diacetyl vapor, when excited by UV light.

Modeling and simulation of the gas behavior in a gas centrifuge rotor in the presence of hydrogen fluoride light gas by DSMC and Onsager-pancake [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2021
The gas behavior within a centrifuge machine can be divided into molecular and continuum. The Boltzmann equation is an accurate method for studying the behavior of gas in all areas of a centrifuge.

Adsorption Equilibrium and Mechanism and of Water Molecule on the Surfaces of Molybdenite (MoS2) Based on Kinetic Monte-Carlo Method

open access: yesMolecules, 2022
The oxidation/weathering of molybdenite (MoS2) is too slow to be monitored, even under pure oxygen and high temperatures, while it proceeds rapidly through humid air.
