The individual cellulose nanofibres in aqueous dispersions had been negatively stained with one% phosphotungstic acid prior to the TEM imaging using a Tecnai ST20 200 kV (Fig. 3a–d). Slender aerogels ended up fabricated and dried on 300-mesh Au carbon movie TEM grids for imaging in order to avoid achievable variations https://ammonk421obp5.blogozz.com/profile
