Homogenization of a system of elastic and reaction-diffusion equations modelling plant cell wall biomechanics [PDF]
, 2015 In this paper we present a derivation and multiscale analysis of a mathematical model for plant cell wall biomechanics that takes into account both the microscopic structure of a cell wall coming from the cellulose microfibrils and the chemical reactions

Processing of Polymer Nanocomposites Reinforced with Polysaccharide Nanocrystals
Molecules, 2010 Aqueous suspensions of polysaccharide (cellulose, chitin or starch) nanocrystals can be prepared by acid hydrolysis of biomass. The main problem with their practical use is related to the homogeneous dispersion of these nanoparticles within a polymeric ...

Preferred crystallographic orientation of cellulose in plant primary cell walls
Nature Communications, 2020 Cellulose is synthesized as microfibrils of β-1,4-linked glucan chains arranged in a crystalline lattice. Here Ye et al. use grazing incidence wide angle X-ray scattering to show that cellulose crystals are preferentially orientated parallel to the plant

Direct Measurement of Plant Cellulose Microfibril and Bundles in Native Cell Walls
Frontiers in Plant Science, 2020 Plants use rigid cellulose together with non-cellulosic matrix polymers to build cell walls. Cellulose microfibrils comprise linear β(1,4)-glucan chains packed through inter- and intra-chain hydrogen-bonding networks and van der Waals forces.

Cellulosic materials as natural fillers in starch-containing matrix-based films: a review [PDF]
, 2016 In this work, the different cellulosic materials, namely cellulose and lignin are analyzed. In addition, the starch-containing matrices (isolated starch and flour) reinforced with cellulosic materials to be used in packaging applications are described ...

Buckling of sheared and compressed microfibrils [PDF]
Journal of The Royal Society Interface, 2010 In this paper, we study the stability of an initially straight elastic fibril clamped at one end, while the other end is subjected to a constant normal compressive force and a prescribed shear displacement. We found the buckling load of a sheared fibril to be always less than the Euler buckling load. Furthermore, if the end of the fibril loses adhesion,

Cellulose nanocrystals-microfibrils biocomposite with improved membrane performance
Carbohydrate Polymer Technologies and Applications, 2023 This study investigates eco-friendly membrane biocomposites derived from biomass, utilizing cellulose microfibrils (CMF) as the main membrane material. Cellulose nanocrystals (CNC), isolated from rice husk, were added as reinforcing fillers in CMF flat ...
