Genotoxicity of Three Micro/Nanocelluloses with Different Physicochemical Chara...
Ventura, Célia; Marques, Catarina; Cadete, João; Vilar, Madalena; Pedrosa, Jorge F. S.; Pinto, Fátima; Fernandes, Susete NogueiraBackground: Nanocellulose is an innovative engineered nanomaterial with an enormous potential for use in a wide array of industrial and biomedical applications and with fast growing economic value. The expanding production of nanocellulose is leading to an increased human exposure, raising concerns about their potential health effects. This study was aimed at assessing the potential toxic and genotoxic effects ...

A cellulose liquid crystal motor: a steam engine of the second kind
Geng, Yong; Almeida, Pedro L.; Fernandes, Susete Nogueira; Cheng, Cheng; Palffy-Muhoray, Peter; Godinho, Maria HelenaThe salient feature of liquid crystal elastomers and networks is strong coupling between orientational order and mechanical strain. Orientational order can be changed by a wide variety of stimuli, including the presence of moisture. Changes in the orientation of constituents give rise to stresses and strains, which result in changes in sample shape. We have utilized this effect to build soft cellulose-based mot...
