Abstract

The results of positron annihilation lifetime (PAL) measurements of the Juniperus communis based biomaterial NEFROVIL are reported for the first time. Three- and four-component fittings were applied to deconvolute the PAL spectrum. In order to determine which fitting procedure is most suited, a maximum entropy lifetime (MELT) analysis was also performed. It was found that the nanovoid topology of this biomaterial is constructed by small and large free-volume holes identified by the ortho-positronium lifetime parameters in the most suitable four-component fitting procedure.
