Energy dissipation capability and impact response of carbon nanotube buckypaper: A coarse-grained molecular dynamics study

Effect of Carboxylation on Carbon Nanotube Aqueous Dispersibility: A Predictive Coarse-Grained Molecular Dynamics Approach

Functionalized single-walled carbon nanotubes (SWNTs) are widely applied in biomedical science. To understand the interaction between SWNTs and biological systems, various studies have attempted to use coarsegrained molecular dynamics (CGMD). However, there is limited validation of the existing CG models of SWNTs. Here, we present CG models for both pristine and carboxylated SWNTs which are val...

Coarse Grained Molecular Dynamics

Coarse-grained molecular dynamics study of cyclic peptide nanotube insertion into a lipid bilayer.

Coarse-grained (CG) molecular dynamics (MD) simulations are performed to study the insertion of cyclic peptide nanotubes into cell membranes and to examine whether cyclic peptide nanotubes can function as an ion channel and thereby as an antibacterial agent. To do so, the two coarse-grained (CG) models for lipid molecules and for proteins developed by Marrink et al. (J. Phys. Chem. B 2004, 108,...

Energy dissipation mechanisms in carbon nanotube oscillators.

Energy transfer from the translational degrees of freedom to phonon modes is studied for isolated systems of two coaxial carbon nanotubes, which may serve as a nearly frictionless nano-oscillator. It is found that for oscillators with short nanotubes (less than 30 A) a rocking motion, occurring when the inner tube is pulled about 1/3 out of the outer tube, is responsible for significant phonon ...

Coarse-grained molecular dynamics simulations of biomolecules

Coarse-grained molecular dynamics (CGMD) simulations are increasingly being used to analyze the behaviors of biological systems. When appropriately used, CGMD can simulate the behaviors of molecular systems several hundred times faster than elaborate all-atom molecular dynamics simulations with similar accuracy. CGMD parameters for lipids, proteins, nucleic acids, and some artificial substances...
