Snapshots At The Atomic Border
Abstract:
Scientists from the Max Planck Institute for Metals Research in Stuttgart and the Israel Institute of Technology in Haifa have now been able to observe atomic processes at the interface between liquid aluminium and solid aluminium oxide (sapphire). Using high voltage electron microscopy, they were able to show that crystals are able to order the atoms in neighbouring liquid metals, even at high temperatures. The results are important for procedures such as the wetting of joints in nanoscale "soldering."
