Nano world made large. Here in the Giga-indentation exhibit we show what our materials are made
out of and what holds the building blocks called atoms together, using a model of a novel material
called graphene as an example. You will see what ultimately defines the mechanical material strength
by analyzing the elastic deformation of the material after adding a weight on top of it.
After that, you will see how we can impact the mechanical strength of the material by changing the
atomic structure. The is to remove individual atoms from the lattice, which you will achieve by
shooting other atoms onto the material. Successful impacts result in vacancies left behind at the
impact site.
The introduction of these defects will impact the material properties, including the mechanical
strength. You will see how this material property change is quantified in this up-scaled analogy
experiment.
