In this paper, mesoscopic lattice–Boltzmann method (LBM) and microscopic molecular dynamics simulation method were used to simulate droplet dynamic wetting under microgravity. In terms of LBM, the wetting process of a droplet on a solid wall surface was simulated by introducing the fluid–fluid and solid–fluid interactions. In terms of molecular dynamics simulation, the spreading process of water on gold surface was simulated. Calculation results showed that two kinds of calculation methods were based on the microscopic molecular theory or mesoscopic kinetics theory, and such models could effectively overcome the contact line paradox issue, which results from the macro-continuum assumption and non-slip boundary condition assumption. The spreading exhibits two-stage behavior: fast spreading and slow spreading stages. For the two simulation methods, the ratio of fast spreading stage duration to slow spreading duration, spreading capacity (equilibrium contact radius/initial radius), and the spreading exponent of the rapid stage were very close. However, the predictive spreading index of the slow spreading stage was different, owing to the different spreading mechanisms between meso- and nanoscales.

Lysine dendrimers and dendrigrafts are often used in biomedicine for drug and gene delivery to different target organs or cells. In present paper the possibility of complex formation by lysine dendrigraft and 16 molecules of therapeutic KED peptide was investigated using molecular dynamics simulation method. A system containing of one dendrigraftt and 16 KED peptides in water were studied. It was shown that stable complex consisting of the dendrigraft and the peptide molecules formed and structure of this complex was studied. Similar complexes could be used in future for delivery of other therapeutic peptides to target organs.

The nanoindentation of diamond crystal [100] surface is studied in this paper, by using molecular dynamics simulation method and Tersoff potential. The total number of atoms in the model is exceed to 2,000,000. The crystal structure changes and the bond formations of C atoms under pressure load are analyzed. A light load causes lattice distortion but cannot cause bond breaking or hybridization transition from sp3 to sp2. When the load is enough heavy, the energy be imposed on the workpiece will beyond the range of lattice distortion, which can cause bond break and hybridization transition from sp3 to sp2.

AbstractThis work presents a molecular dynamics simulation method designed to describe the processes of electron and lattice relaxation taking place in typical cascade volumes formed by high-energy implants. The simulation method is based on classical mechanics and includes the motions of electrons and nuclei. The results are in agreement with experiments.

Molecular dynamics simulation method was used to study the rarefied gaseous flows in nanochannels. A pressure-driven force was introduced to drive the gas to flow between two parallel walls. The effects of driven force magnitude and channel height were investigated. The results show that a single layer of gaseous molecules is adsorbed on the wall surface. The density of adsorption layer decreases with the increase of channel height, but doesnt vary with driven force. The velocity profile across the channel has the traditional parabolic shape. The average velocity and gas slip velocity on the wall increase linearly with the increase of pressure-driven force. The gas slip velocity decreases linearly with the increase of channel height. The ratio of slip to average velocity decreases linearly with the increase of channel height.
