Characterization of nanoscale porosity of aerogels was also carried out with Nitrogen adsorption–desorption measurements, which have been performed on a Quantachrome NOVA contact pore analyser at 77 K. Before these measurements, the aerogel samples (about fifty mg Every) had been saved at sixty °C for 48 h, outgassed underneath vacuum https://gailk420nan4.shopping-wiki.com/user
