Characterization of nanoscale porosity of aerogels was also completed with Nitrogen adsorption–desorption measurements, which have been performed with a Quantachrome NOVA contact pore analyser at 77 K. Before these measurements, the aerogel samples (about fifty mg each) have been kept at 60 °C for forty eight h, outgassed underneath vacuum https://beauty-water66532.fare-blog.com/26419415/bespoke-secondary-glazing-in-bloomsbury-fundamentals-explained
