Characterization of nanoscale porosity of aerogels was also performed with Nitrogen adsorption–desorption measurements, which were done on the Quantachrome NOVA contact pore analyser at 77 K. Prior to these measurements, the aerogel samples (about 50 mg each) were stored at 60 °C for forty eight h, outgassed underneath vacuum at https://barbarad321ulb0.wikigop.com/user
