Extensional viscosity of microfibrillated cellulose suspensions
Carbohydrate Polymers, 2014The extensional properties of micro fibrillated cellulose (MFC)-suspensions at different fibril concentrations and with different amounts of added sodium chloride were evaluated. The MFC-suspensions were obtained by diluting a stock solution consisting of 0.95 wt.% cellulose with either deionized water or sodium chloride solution, giving a series of ...

Comparison of Rhapidosomes and Asbestos Microfibrils
Science, 1978Rhapidosomes (cylindrical nucleoprotein rods of bacterial origin) show great structural similarity to the microfibrils of chrysotile asbestos when negatively stained and observed with the electron microscope. If the negative stain is omitted, the asbestos retains its structural detail whereas the rhapidosomes appear to be unstructured bodies.

The substructure of α-keratin microfibrils
Journal of Ultrastructure Research, 1970The effect of underfocusing on the fine detail observed in the cross section of α -keratin microfibrils is discussed. It is shown that the apparent subdivision of the microfibrils into protofibrillar elements is coincidental with an underfocused granular phase image of similar dimensions and cannot, therefore, be accepted as a genuine structural ...

Studies on microfibrils from α-keratin
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1976alpha-Keratin microfibrils have been isolated from the presumptive cortex of developing mammalian hair follicles and purified by a centrifugation procedure. They have been obtained on a scale sufficient to enable their physical and chemical nature to be studied directly.

Process for the production of microfibrillated cellulose and produced microfibrillated cellulose
2010A 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 Build Architecture: A Geometrical Model
2001ABSTRACT Several mechanisms for cellulose microfibril (CMF) orientation have been proposed, of which guidance by cortical microtubules is widely accepted for growing cells, but in many non-growing cells CMF orientations are not correlated to microtubule arrangement.
