Aluminium plates which have only been sandblasted (in the background of the picture) cannot be glued successfully. The two glued plates separate again at the interface between glue and metal – this can be seen by the fact that there is no white glue residue visible on one of the two plates.

But the white glue particles left on both plates demonstrate that the bond between metal and glue is not broken, but rather the glue itself. Credit: Photo/Copyright: Julia Siekmann / Kiel University
Through this “nanoscale-sculpturing” process, metals such as aluminium, titanium, or zinc can permanently be joined with nearly a...
