The invention relates to a composition containing a particulate solid, a plastic material and a compound capable of having dispersant properties. The improved methodology provides an eco-friendly, cheaper, practical and efficient approach to functionalize carbon nanotubes with oxygen-containing moieties for further chemical functionalization and composite dispersion. The stator also has a carrier structure holding the bars such that they are fixed in relation to each other, said carrier structure being mounted in such a way that it can rotate on the shaft, axially outside the two disks. The sterile first tool is moved relative to the sterile second tool to apply deformation forces to the at least a portion of the sterile medical implant for contouring the sterile medical implant at a deformation portion of the sterile medical implant, located between the sterile first and second tools.
