The individual cellulose nanofibres in aqueous dispersions were negatively stained with one% phosphotungstic acid prior to the TEM imaging employing a Tecnai ST20 200 kV (Fig. 3a–d). Slender aerogels have been fabricated and dried on three hundred-mesh Au carbon film TEM grids for imaging to stay away from possible variations https://bertiet985fwm5.blogolenta.com/profile
