Determination of cellulose crystallinity from powder diffraction diagrams.
TL;DR: One‐dimensional (1D) (spherically averaged) powder diffraction diagrams are commonly used to determine the degree of cellulose crystallinity in biomass samples but disorder in cellulose fibrils can lead to considerable uncertainty in conclusions drawn concerning crystallinity based on 1D Powder diffraction data alone.
Journal ArticleDOI
Quenched disorder and spin-glass correlations in XY nematics
TL;DR: In this paper, the authors present a theoretical study of the equilibrium ordering in a 3D XY nematic system with quenched random disorder and show that the correlation length is obtained as a function of the local nematic order parameter Q and the effective disorder strength.
Journal ArticleDOI
Structure and dynamics of a complex of cellulose with EDA: insights into the action of amines on cellulose
Daisuke Sawada,Yoshiharu Nishiyama,Loukas Petridis,Ramakrishnan Parthasarathi,Sandrasegaram Gnanakaran,V. Trevor Forsyth,Masahisa Wada,Masahisa Wada,Paul Langan +8 more
TL;DR: The neutron structure of a complex of EDA with cellulose has been determined to reveal the location of hydrogen atoms involved in hydrogen-bonding, and quantum chemistry and molecular dynamics calculations show that O3 prefers to donate to EDA as discussed by the authors.
Journal ArticleDOI
The relation between lignin sequence and its 3D structure.
TL;DR: The results presented here demonstrate there are no significant differences in the 3D structure of lignin molecules with the same average composition but different primary sequence, and the overall content of monomeric units and interunit linkages is influenced by its precise primary sequence.
Journal ArticleDOI

TL;DR: A fundamental understanding of the processes involved in the production of biofuels from lignocellulosic biomass is provided and a variety of neutron scattering technologies are available to elucidate both the organization and deconstruction of this complex composite material.
