While at small collision velocities collisions of nanoparticles (NPs) are elastic, they become plastic at higher velocities. We study the elastic-plastic threshold and the onset of plasticity …
When nanoparticles (NPs) collide with low velocities, they interact elastically in the sense that–besides their fusion caused by their mutual van-der-Waals attraction–no defects are …
We show that amorphous silica and Si nanotubes can flow at room temperature under Giga- Pascal order stress when going to the nanometer scale. This creep behavior is unique for …
