Physically based 3D finite element model of a single mineralized collagen microfibril [PDF]
Journal of Theoretical Biology 301 (2012) 28-41, 2012 Mineralized collagen microfibrils in human bone provide its mechanical properties (stiffness, elasticity, ductility, energy dissipation and strength). However, detailed 3D finite element models describing the mechanical behaviour of the mineralized collagen microfibrils are still lacking.

Initiator-free photo-crosslinkable cellulose-based resists for fabricating submicron patterns via direct laser writing [PDF]
, 2022 Novel bifunctional cellulose diacetate derivatives were synthesized in order to achieve bio-based photoresists, which can be structured by two-photon absorption via direct laser writing (DLW) without the need to use a photoinitiator. Therefore, cellulose diacetate is functionalized with thiol moieties and olefinic or methacrylic side groups enabling ...

Resonant soft X-ray scattering reveals cellulose microfibril spacing in plant primary cell walls
Scientific Reports, 2018 Cellulose microfibrils are crucial for many of the remarkable mechanical properties of primary cell walls. Nevertheless, many structural features of cellulose microfibril organization in cell walls are not yet fully described.

Dispersion of Boron Nitride Powders in Aqueous Suspensions with Cellulose [PDF]
Bouville, F., & Deville, S. (2014). Dispersion of boron nitride
powders in aqueous suspensions with cellulose. Journal of the American
Ceramic Society, 97(2), 394-398, 2017 The dispersion of nitride and carbide ceramic particles in water is difficult, due to the absence of hydroxyl groups on their surface. Boron nitride is not an exception and despite its numerous applications, no effective dispersant has been identified so far. We demonstrate here the dispersion properties of two cellulose derivatives for hexagonal boron

Isolation of Cellulose Nanofibers: Effect of Biotreatment on Hydrogen Bonding Network in Wood Fibers
International Journal of Polymer Science, 2011 The use of cellulose nanofibres as high-strength reinforcement in nano-biocomposites is very enthusiastically being explored due to their biodegradability, renewability, and high specific strength properties. Cellulose, through a regular network of inter-

Hydrogen bonds and twist in cellulose microfibrils [PDF]
Carbohydrate Polymers, 2017 There is increasing experimental and computational evidence that cellulose microfibrils can exist in a stable twisted form. In this study, atomistic molecular dynamics (MD) simulations are performed to investigate the importance of intrachain hydrogen bonds on the twist in cellulose microfibrils.

Electronic Band Structures of Pristine and Chemically Modified Cellulose Allomorphs [PDF]
, 2020 We have investigated the structural properties, vibrational spectra, and electronic band structures of crystalline cellulose allomorphs and chemically modified cellulose with quantum chemical methods. The electronic band gaps of cellulose allomorphs I$_\alpha$, I$_\beta$, II, and III$_1$ lie in the range of 5.0 to 5.6 eV.
