Finite element 3D modeling of mechanical behavior of mineralized collagen microfibrils [PDF]
, 2011 The aim of this work is to develop a 3D finite elements model to study the nanomechanical behaviour of mineralized collagen microfibrils, which consists of three phases, (i) collagen phase formed by five tropocollagen (TC) molecules linked together with cross links, (ii) a mineral phase (Hydroxyapatite) and (iii) impure mineral phase, and to ...

Detecting the orientation of newly-deposited crystalline cellulose with fluorescent CBM3
The Cell Surface, 2022 Cellulose microfibril patterning influences many of the mechanical attributes of plant cell walls. We developed a simple, fluorescence microscopy-based method to detect the orientation of newly-synthesized cellulose microfibrils in epidermal peels of ...

Melt Processing of Cellulose Acetate for Controlled Release Applications – A Review
Macromolecular Materials and Engineering, EarlyView.This review presents recent developments in the melt‐processing of cellulose acetate (CA). Factors affecting the processability, biodegradability, and mechanical performance of CA are also summarized. Plasticizers, bio‐based polymers (PLA, PBAT & PHBV), and clay nanoparticles are also examined toward enhancing the melt processability and mechanical ...

Structural and Material Properties of Chitin Nanofibers Produced Without Deacetylation Treatment
Nano Select, EarlyView.In this study, we prepared chitin nanofibers with a width of several nanometers without the need for a deacetylation process. We examined their structural properties, such as their morphology, surface charge, colloidal stability, and material performance, including their emulsifying capabilities and film properties, by comparing them with those of ...

Homogenization of a viscoelastic model for plant cell wall biomechanics [PDF]
arXiv, 2015 The microscopic structure of a plant cell wall is given by cellulose microfibrils embedded in a cell wall matrix. In this paper we consider a microscopic model for interactions between viscoelastic deformations of a plant cell wall and chemical processes in the cell wall matrix.

Structure of cellulose microfibrils in mature cotton fibres [PDF]
Carbohydrate Polymers, 2017 The structure of cellulose microfibrils in mature cotton fibres from three varieties - Gossypium hirsutum, G. barbadense and G. arboreum - has been investigated by a multi-technique approach combining small angle scattering techniques with spectroscopy and diffraction.

Model surfaces for paper fibers prepared from carboxymethyl cellulose and polycations [PDF]
arXiv, 2021 For a tailored functionalization of cellulose based papers, the interaction between paper fibers and functional additives have to be understood. Planar cellulose surfaces present a suitable model system for studying the binding of additives. In this work, polyelectrolyte multilayers (PEMs) as model surfaces are prepared by alternating dip coating of ...

Polymer Composites, EarlyView.From fiber modification to composite panels. Abstract The widespread use of environmentally friendly medium‐density fiberboard (MDF) panels as a wood composites is driven by their versatility, affordability, and durability. However, reliance on traditional wood preservatives and modifications raises significant environmental, health, and cost concerns ...

Properties of Polymer Composites with Cellulose Microfibrils [PDF]
, 2011 Polypropylene-based composites containing 10–30% by weight cellulose microfibrils were studied. Composites with polypropylene and cellulose microfibrils were characterised by MS-coupled simultaneous TGA-DSC and the reinforcing effect of cellulose microfibrils was emphasised by mechanical characterization.
