Positron Annihilation Spectroscopy (PAS) performed with continuous and pulsed positron beams allows to characterize the size of the intrinsic nano-voids in silica glass, their in depth modification after ion implantation and their decoration by implanted ions. Three complementary PAS techniques, lif

Secondary ion yields are known to be strongly enhanced by the presence of oxygen in the analysed sample. The magnitude of the yield enhancement is often signiΓcantly di β erent for impurity and matrix ion species. This kind of SIMS matrix e β ect severely aggravates concentration calibration in depth
## Abstract This __in vivo__ study evaluated the fixation of two types of titanium implants with the use of an injectable calciumβphosphate (CaP) cement. The cement was either used to create a cement mantle (Type A implant) or as an additive to pressβfit placed titanium plasma sprayed implants (Typ
