New Tech Studies Small Clusters of Atoms
Physicists at the Univ. of York, working with researchers at the Universities of Birmingham and Genoa, have developed new technology to study atomic vibration in small particles, revealing a more accurate picture of the structure of atomic clusters where surface atoms vibrate more intensively than internal atoms.
Using new computer technology based on gaming machines, scientists were able to use a combination of molecular dynamics and quantum mechanics calculations to simulate the electron microscopy of gold particles. By modelling the atomic vibration of individual atoms in such clusters realistically, external atoms on the surface of the structure can be seen to vibrate more than internal atoms.
