研究開始時の研究の概要 |
In this project we will study the water difussion in nanocomposite membranes of polyamide and carbon nanotubes, and will make emphasis on two points: scalability and the use of molecular dynamics derived thermodynamic properties. We will also use the charge equilibration method and expand the molecular dynamics methods to carry out an empiric stochastic diffusion analysis. We will implement recent technological innovations in molecular dynamics, such as GPU-based computers, implementation of parallel processing, and new tools based in artificial intelligence and machine learning.
