Résumé

An abstract was not provided in the original work, so a preliminary abstract has been prepared as follows. The discussion focused on the structure and function of natural proteins for water transport and examined, among other things, Finkelstein's model of the movement of water molecules. It was discussed that these water molecules move as a unit with a coefficient of friction proportional to the number of molecules, but do not allow electroosmotic transport in the opposite direction of water flow because of their narrow width. The entropy of water molecules entering the nanotubes has also been discussed. There is evidence that entropy increases for certain tube sizes and water distances. The group discussed that the activation barrier can only be determined by measuring the permeabilities at different temperatures, with the pores of carbon nanotubes having the highest water permeability and thus the lowest activation energy, which is even lower than the best of the aquaporins.
