Characterization of nanoscale porosity of aerogels was also completed with Nitrogen adsorption–desorption measurements, which were being performed over a Quantachrome NOVA touch pore analyser at 77?K. Just before these measurements, the aerogel samples (about fifty?mg each) had been retained at sixty?°C for forty eight?h, outgassed below vacuum
