Random movement of Nano particles in nano containers

The movement of metallic nano particles inside liqui nano
containers was studied by Transmission electron microscopy. The size
of the liquid container size varies between the size of the
nano-particle to few times the that size. The movement of the
nano-particles was found to be correlated with rearrangement of the
atoms (quasi-melted state). The rearrangement of the atomic order was
intensively studied for lead and for bismuth nano-particles at various
temperatures (references 1-3). Here we will present for the 1st time
the movement of nano particles inside ~25nm gallium container. The
movement is at visible rate and has a billiard appearance with
scattering from the container?s edges. Analysis of the movement
indicates that the movement can not be explained by the classical
rules as for rigid bodies. References 1. A. Be?er, R. Kofman,
