Study of aged-polypyrrole by positron annihilation spectroscopy
The thermal ageing behaviour of para-hydroxybenzene sulfonate doped polypyrrole is studied using positron annihilation spectroscopy. The conducting polymer is synthesized by a chemical oxidation process and aged at 140 ○C in air up to 48 days.The ...

Spatially resolved positron annihilation spectroscopy on friction stir weld induced defects
A friction stir welded (FSW) Al alloy sample was investigated by Doppler broadening spectroscopy (DBS) of the positron annihilation line. The spatially resolved defect distribution showed that the material in the joint zone becomes completely annealed ...
