Characterization of nanoscale porosity of aerogels was also performed with Nitrogen adsorption–desorption measurements, which had been carried out with a Quantachrome NOVA contact pore analyser at 77 K. Prior to these measurements, the aerogel samples (about 50 mg each) were retained at sixty °C for 48 h, outgassed underneath vacuum https://rachelg332xne2.myparisblog.com/profile
