dynamics of molecules in graphite - sciencedirect

Molecular

The dynamical excitations in a commensurate monolayer solid of NSUB2/SUB molecules adsorbed on graphite have been studied using molecular-dynamics simulations. Velocity and rotational correlation functions as well as coherent intermediate scattering functions and dynamical structure factors have been calculated at several temperatures and wave vectors. Effects of out-of-plane motions and

The structure of graphene on graphene/C60/Cu interfaces:

Two experimental studies reported the spontaneous formation of amorphous and crystalline structures of C 60 molecules intercalated between graphene and a surface. The findings observed included interesting phenomena ranging from reaction between fullerene C 60 s ('C 60 s' stands for plural of C 60) under graphene to graphene sheets sagging between C 60 s and control of strain in these sheets.

Polarizability effects in molecular dynamics simulations

The importance of including the polarizability of both water and graphene in molecular dynamics simulations of the water/graphene system was quantified. A thin film of either rigid single point charge extended (SPC/E) water or polarizable simple 4-site water model with Drude polarizability (SWM4_DP) water on non-polarizable and polarizable graphene surfaces was simulated.

Wetting transition of water on graphite and boron

Graphite Boron-nitride abstract Wetting transition of water on graphite and boron-nitride (BN) surfaces is investigated by molecular dynamics simulation. In particular, we report the effect of temperature and system size on the contact angle of water droplet on the

Dynamics of chemical bonding mapped by energy

Chemical bonding dynamics are fundamental to the understanding of properties and behavior of materials and molecules. Here, we demonstrate the potential of time-resolved, femtosecond electron energy loss spectroscopy (EELS) for mapping electronic

Hydration behavior and dynamics of water molecules in

2006/5/1In contrast to graphite intercalation compounds, graphite oxide (GO) is hydrophilic. However, the information about the mobility of the water molecules is still sparse. We show in this report that the degree of hydration and the kinetics of water uptake depend crucially on

Multiple structure formation and molecule dynamics in

2020/3/1The dynamics of individual atoms and molecules was studied by selecting the emission systems and recording 8 nm spectral wide images across the whole plasma volume, thus obtaining the spatial distribution of each plasma component in a single step.

Dynamics of Water Intercalated in Graphite Oxide

Intercalated water in graphite oxide (GO) was investigated by using different techniques: broadband dielectric spectroscopy (BDS) (10−2−109 Hz; 140−300 K), differential scanning calorimetry, X-ray diffraction, and attenuated total reflection geometry in Fourier transform infrared spectroscopy (ATR-FTIR). We have studied the water concentration (cw) region from 0 wt % (anhydrous GO) up to

(PDF) Hydration behavior and dynamics of water

However, the information about the mobility of the water molecules is sparse. In order to get the information about the water dynamics, we carried out quasi-elastic neutron scattering experiments. In preparing the samples for these studies, we found to our surprise that the degree of hydration and the kinetics of water uptake depend crucially on the preparation and aging conditions.

Molecular

The dynamics of commensurate submonolayer solids of N 2 molecules adsorbed on the basal planes of graphite have been studied using molecular-dynamics simulations. The calculations yielded the temperature dependence of the Brillouin-zone-center gap in the acoustic-phonon branches, for comparison with inelastic neutron-scattering experiments on the submonolayer solid.

A multivalent hexapod: conformational dynamics of six

2009/4/28Scanning tunneling microscopy reveals that molecules adsorb in 2D crystalline as well as disordered domains. Strikingly, not all molecules have the six OPV units in contact with the graphite substrate: 4% of the molecules in the 2D crystalline domains and up to 80% of the molecules in the disordered domains have one or two OPV units desorbed.

Structure and dynamics of TIP3P, TIP4P, and TIP5P water

We implement walls of different hydroaffinity, different lattice constant, and different types of interaction with the water molecules. We find that in the hydrophobic regime the smooth wall generally represents a good abstraction of the atomically rough walls, while in the hydrophilic regime there are noticeable differences in structure and dynamics between all stages of wall roughness.

Diffusion behavior of benzene/cyclohexane molecules in

2007/2/1Effects of graphite particles on the diffusion behaviour of PVA-graphite hybrid membranes are investigated by molecular dynamics (MD) simulation. The calculation results of interaction energy show that with the increase of PVA-graphite interaction, the intramolecular interaction between polymer chains becomes weaker.
