Abstract: This work deals with the use of positron annihilation lifetime spectroscopy (PALS) for the study of hexadecane confined in SiO2 aerogel. The temperature dependencies of the o-Ps lifetime and intensity for this material were compared with values of hexadecane confined in silicagel with a similar average pore size. The results of differential scanning calorimetry (DSC) for both these materials will be discussed.

Abstract: Results of positron annihilation experiments on bulk hexadecane and hexadecane filled into silica gel nano pores will be reported. The lifetime and Doppler broadening measurements were performed at the temperature range (14-300) K. The annihilation data were combined with output of the differential scanning calorimetry at range from 270K up to 300K.
