Monitoring the Crystallization Stages of Silicalite by Positron Lifetime Spectroscopy

Materials Science Forum, 2008
In porous media, positron annihilation techniques (PAT) revealed the existence of annihilation modi with long lifetimes connected to structural and extrastructural free volumes acting as trapping centres for o-Ps. Our aim in this work was to study the influence of the synthesis applied for the production of the zeolite framework and the correlation ...

Positron Lifetime Spectroscopy to Study Defects in Solids

Solid State Phenomena
Positron lifetime spectroscopy is a powerful non-destructive technique for characterizing open-volume lattice defects in solids at the atomic scale. This technique enables the identification of defects and the determination of defect concentration.
