MODEL OF NANOTUBE FORMATION IN SOLUTION UNDER MOLECULAR SORPTION CONDITIONS

摘要

Reliable disposal of radioactive wastes in nanosize containers which ensure that the wastes are isolated and strongly contained is investigated. A model of the process of incorporating impurity components into solutions where nanotubes are formed is presented to substantiate the possibility considered. An attempt is made to describe the rolling up of nanotubes in a liquid medium from the standpoint of the energy balance in a system that consists of a nanometer-size thin film and molecules which are sorbed on its surface from solution. The results show that when molecules are sorbed from solution onto a nanolayer surface the layer rolls up. The possibility that a roll or nanotube loses stability when sorbed molecules are present in them must be taken into account when studying the final state of the nanolayer.
