Method for obtaining the Knudsen diffusion coefficient

open access: yesMethodsX, 2018
Recently, we developed a method for obtaining the Knudsen diffusion coefficient from the results of tracer experiments with a binary gas system and a porous medium in a column.

Viscosity and mass diffusion coefficient of ammonia/ethylammonium nitrate mixtures

open access: yes, 2021
Ethylammonium nitrate shows an enhanced ammonia solubility due to the formation of strong hydrogen bonds. This protic ionic liquid also shows negligible vapour pressure and shares many properties with water.

From the diffusion coefficient to the diffusion tensor [PDF]

open access: yesNMR in Biomedicine, 2002
AbstractWith diffusion tensor MRI one has access to the organization in space of tissue microstructural components. This outstanding potential adds, however, another layer of complexity to the diffusion MRI data acquisition and analysis processes. Over the last few years many articles have been published dealing with those matters.

Controlled Laboratory Experiments on Radon Diffusion Coefficient

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
Radon which occurs inuranium decay series is a noble gas and it moves from the deeper layers of theearth crust to the atmosphere. Formation of the radon gas in the Earth's crustand its migration to atmosphere are quite complex process because of too ...
