Cellulose whiskers versus microfibrils: influence of the nature of the nanoparticle and its surface functionalization on the thermal and mechanical properties of nanocomposites.

Biomacromolecules, 2009
In the present work, nanowhiskers and microfibrillated cellulose (MFC) both extracted from sisal were used to reinforce polycaprolactone (PCL). We report the influence of the nanoparticle's nature on the mechanical and thermal properties of the ensuing ...

Elastic modulus of single cellulose microfibrils from tunicate measured by atomic force microscopy.

Biomacromolecules, 2009
The elastic modulus of single microfibrils from tunicate ( Halocynthia papillosa ) cellulose was measured by atomic force microscopy (AFM). Microfibrils with cross-sectional dimensions 8 x 20 nm and several micrometers in length were obtained by ...

Immunolocalization of microfibril and microfibril-associated proteins in the subendothelial matrix of the developing mouse aorta

Journal of Cell Science, 1994
ABSTRACT In the developing aorta, endothelial cell connecting filaments extend from the abluminal surface of the endothelial cell to the subjacent elastic lamina. The connecting filaments are in alignment with intracellular stress fibers and are oriented parallel to the direction of blood flow.

The Supramolecular Organization of Collagen VI Microfibrils

Journal of Molecular Biology, 2003
Collagen VI has a ubiquitous distribution throughout connective tissues, and has key roles in linking cells and matrix macromolecules. We have generated three-dimensional reconstructions of collagen VI microfibrils using automated electron tomography (AET) in order to obtain new insights into the organisation of collagen VI in assembled microfibrils ...

Process for the production of microfibrillated cellulose and produced microfibrillated cellulose

2010
A process for producing microfibrillated cellulose comprises providing a slurry comprising cellulosic fibers, treating the slurry with an enzyme, mechanically treating the slurry so that the fibers are disintegrated wherein the mechanical treatment and the treatment with the enzyme is performed simultaneously in a single treatment step.

Microfibrils from the Arterial Subendothelium

1999
Microfibrillar structures of the subendothelium are represented by either type VI collagen or elastin-associated microfibrils which are also referred to as fibrillin-containing microfibrils. These structures are present throughout the subendothelium irrespective of the presence of elastin.

Mircofibrils in the Aorta

Connective Tissue Research, 1983
Ruthenium red was used to stain microfibrils in rat aorta after incubation of the tissues with or without one of the enzymes trypsin, collagenase, phospholipase C, chondroitinase ABC, hyaluronidase or neuraminidase, or the reducing agent dithiothreitol.

Organization and Biomechanical Properties of Fibrillin Microfibrils

2004
The evolution and function of multicellular organisms has required tissue flexibility and the necessity to withstand stretch. These properties underpin movement and allow responses to changing environments. The elastic fibre is a bio-composite material composed of two insoluble extracellular matrix assemblies; fibrillin-rich microfibrils and elastin ...
