Abstract Double-roll compaction is a process to create extensible paper and paperboard suitable for replacing plastic in 3D forming applications. Understanding the macro- micro-mechanisms governing allows increasing stretch potential while maintaining sufficient strength bending stiffness. In this work, we approach of with micro-mechanical methods featuring unprecedented level details otherwise...

Nanoparticles are commonly used in various fields of applications such as electronics, catalysis or engineering where they can be subjected to a certain amount stress leading structural instabilities irreversible damages. In contrast with bulk materials, nanoparticles sustain extremely high stresses (in the GPa range) and ductility, even case originally brittle materials. This review article fo...
