Hexadecane in SiO2 Aerogels

Abstract:

Article Preview

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.
