Publisher Copyright: © 2022 Walter de Gruyter GmbH, Berlin/Boston 2022. Paper-grade pulp, rich in hemicellulose content, is a cheap source for producing dissolving pulps. The main challenge in the conversion of a cheap paper-grade pulp to a higher-v
Stinging nettle (Urtica dioica) is a potential source material for industrial applications. However, systematic research on the ultrastructural properties of nettle fibres is lacking. Determining the ultrastructure of nettle and the other bast fibres
