New Scientist Tech - Breaking News - Nano-welding could join molecular devices: "A nanoscale welding technique has been developed by sparking high-temperature chemical reactions inside 'nanopores'.
The technique could ultimately be used to weld together nanoscale components and could also lend itself to nanoscopic chemistry experiments, say the researchers.

By lacing a micrometre-thick film of aluminium with nanoscopic holes and filling the holes with iron oxide, the researchers produced a high-temperature 'thermite' reaction. "
