Large metal surfaces can also be treated with nanoscale sculpturing. Although the etching is only applied to a thin layer on a micrometer scale, the resulting change is visible to the naked eye. Photo : Julia Siekmann/CAU

Aluminium plates which have only been sandblasted (in the background of the picture) cannot be glued successfully. The aluminium plates in the foreground of the picture were treated with the etching process “nanoscale-sculpturing” before being glued. Photo: Julia Siekmann/CAU
