بررسی جذب سطحی در نانوکامپوزیتهای گرافن/ اکسیدگرافن- پلیمرهای تقویت شده بهروش شبیهسازی دینامیک مولکولی واکنشی
Abstract: In this work, the amounts of the adsorption of conjugated polymers onto graphene/ graphene oxide were examined by reactive force-field molecular dynamics simulation. The polymers were poly(3-hexylthiophene) (P3HT) and poly(phenothiazine vinylene-polythiophene)(PTZV-PT). The length and width of the graphene sheet were 95.19 Å and 54.16 Å, respectively. The graphene oxide sheets with di...
متن کاملIn Silico Determination of Gas Permeabilities by Non-Equilibrium Molecular Dynamics: CO2 and He through PIM-1
We study the permeation dynamics of helium and carbon dioxide through an atomistically detailed model of a polymer of intrinsic microporosity, PIM-1, via non-equilibrium molecular dynamics (NEMD) simulations. This work presents the first explicit molecular modeling of gas permeation through a high free-volume polymer sample, and it demonstrates how permeability and solubility can be obtained co...
متن کاملMolecular Dynamics Simulation of Water Transportation through Aquaporin-4 in Rat Brain Cells
This paper investigates the mechanism of water transportation through aquaporin-4(AQP4) of ratbrain cells by means of molecular dynamics simulation with CHARMM software. The AQP4 wasembedded into a bilayer made of Dimystroilphosphatylcholine (DMPC). The results illustrate thatwater molecules move through AQP4's channel with change of orientation of oxygen of eachwater molecule.
متن کاملMolecular Dynamics Simulation of Water in Single WallCarbon Nanotube
The overall aim of this study is to calculate some water properties in the single wall carbon naotubes (SWCNT) and compare them to the bulk water properties to investigate the deviation of water properties inside the SWCNT from those in the bulk. Here some physical and transport properties of water molecules in the single wall carbon nanotube were reported by performing molecular dynamics (MD) ...
متن کاملMolecular Dynamics Simulation of Potassium Chloride Melting(.I. Microcrystal Simulation and Sample Size Effect)
The effect of sample size on the melting parameter of simulated potassium chloride microcrystal is investigated by molecular dynamics simulation. The size of microcrystal is varied from 8 to 4096 ions. The increase in melting temperature with sample size was found to be in good agreement with the theory.
