Journal ArticleDOI
A comparative molecular dynamics study of crystalline, paracrystalline and amorphous states of cellulose
Karol Kulasinski,Karol Kulasinski,Sinan Keten,Sergey V. Churakov,Dominique Derome,Jan Carmeliet,Jan Carmeliet +6 more
TL;DR: In this article, the authors apply united-atom molecular dynamics simulations to quantify changes in different morphologies of cellulose and reveal that the paracrystalline phase may be an intermediate, kinetically arrested phase formed upon amorphisation of crystalline cellulose.
Journal ArticleDOI
Water Adsorption in Wood Microfibril-Hemicellulose System: Role of the Crystalline-Amorphous Interface.
TL;DR: A two-phase model of a wood microfibril consisting of crystalline cellulose and amorphous hemicellulose is investigated with molecular dynamics in full range of sorption to understand the molecular origin of swelling and weakening of wood.
Journal ArticleDOI
Highly Carboxylated Cellulose Nanofibers via Succinic Anhydride Esterification of Wheat Fibers and Facile Mechanical Disintegration.
TL;DR: Highly carboxylated CNF from succinic anhydride esterification were effectively integrated into paper filters for the removal of lead from aqueous solution and are potentially of interest as carrier of active molecules or as transparent films for packaging, biomedical or electronic applications.
Journal ArticleDOI
Impact of moisture adsorption on structure and physical properties of amorphous biopolymers
TL;DR: In this paper, a quasi-linear dependence of volumetric strain on moisture content was found, and a linear scaling was found between the volume and porosity of amorphous cellulose and hemicellulose.
Journal ArticleDOI
Molecular mechanism of moisture-induced transition in amorphous cellulose
Karol Kulasinski,Sinan Keten,Sergey V. Churakov,Robert A. Guyer,Robert A. Guyer,Jan Carmeliet,Jan Carmeliet,Dominique Derome +7 more
TL;DR: In this article, the influence of adsorbed water on amorphous cellulose structure and properties, within the full range of moisture content from the dry state to saturation, by molecular dynamics simulation is investigated.
