Form closure

Usage against thermal Van der Waals bond breakage in the low nanoscale - hirachical locking

When the contacting area of two building blocks is made smaller the they wont stick together as strong as before. If the contacting area gets so low that the Van der Waals bonding energy falls in the range of the energy range of the thermal excitations it becomes likely that connections get knocked open just by chance.

Examples for possible solutions of this problem:

• chain that uses shape locking
• serial hierarchical locking structure

Usage in bigger scales

To make assembly reversible with low energy turnover while retaining near full material strength

• Expanding ridge joint
• Recycling

Usage in hierarchies
