On the thermodynamics of carbon nanotube single-file water loading: free energy, energy and entropy calculations

Chris Oostenbrink
Single-file water chains confined in carbon nanotubes have been extensively studied using molecular dynamics simulations. Specifically, the pore loading process of periodic (6,6) and (5,5) single-walled carbon nanotubes was thermodynamically characterized by means of free-energy calculations at every loading state and compared to bulk water employing thermodynamic cycles. Long simulations of each end-state allowed for the partitioning of the free energy into its energetic and entropic components. The calculations revealed that the initial loading states are dominated by entropic (both translational and rotational) components, whereas the latter stages are energetically driven by strong dipolar interactions among the water molecules in the file.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
