Physical phenomena at interfaces are responsible for many properties of great practical interest in composite materials. Using molecular dynamics simulations, we modeled and studied the microscale physics involved in mechanical properties of polymers and in thermal transfer in nanofluids. Developing a method for local study of dynamics in a polymer melt, we have explained the mecha- nisms involved in the mechanical response of a pure melt to an external solicitation. In the case of a wall polymer interface, we have shown that the presence of grafted chains slows down dynamics and increases entanglement density locally in a slice roughly a typical chain size wide. For a bare flat surface dynamics are accelerated and there are less entanglem...
