In this work, research on the ultra-high-speed grinding features of monocrystalline nickel was conducted via molecular dynamics. By the molecular dynamics modeling, calculation and analysis of the grinding process of monocrystalline nickel at various speeds and depths, the changes in the morphology of the grinding chips, grinding force and potential energy at different grinding stages were analyzed...
Highly efficient loading of bone morphogenetic protein-2 (BMP-2) onto carriers with desirable performance is still a major challenge in the field of bone regeneration. Till now, the nanoscaled surface-induced changes of the structure and bioactivity of BMP-2 remains poorly understood. Here, the effect of nanoscaled surface on the adsorption and bioactivity of BMP-2 was investigated with a series of...
Non-equilibrium molecular dynamics simulations are performed to investigate the influences of chemisorption biphenyl rings under axial thermal loadings of 1.65 K/Å. This investigation determines carbon nanotube thermal conductivity at biphenyl rings sorption density ranging from 0%~30%, using a non-equilibrium molecular dynamics simulation with true carbon potentials. The thermal impact causes system...
The present study has investigated the cluster deposition process of thin film formation. MD simulation has been employed to study the morphology of the collision system and to investigate the transient behavior, which occurred between the atoms of the deposited cluster and the substrate. The substrate relaxation process and the influence of the incident energy were also discussed. A traveling condition...
