The individual cellulose nanofibres in just aqueous dispersions had been negatively stained with 1% phosphotungstic acid before the TEM imaging using a Tecnai ST20 200 kV (Fig. 3a–d). Skinny aerogels were fabricated and dried on 300-mesh Au carbon film TEM grids for imaging in order to avoid possible changes of https://hectortmiyo.boyblogguide.com/26074280/rumored-buzz-on-energy-efficient-glazing-in-sw6
