Bioresorbable composites prepared by supercritical fluid foaming

Jan-Anders Edvin Maansson, Dominique Pioletti, Pierre-Etienne Bourban

Bone is a natural composite construct, with a gradient structure going from a loose interconnected cellular core to an outer dense wall, thus minimizing bone weight while keeping a high mechanical resistance. Due to this unique and complex structure, bone ...
