Nanoscale Observation of Microfibril Swelling and Dissolution in Ionic Liquids
, 2018Ionic liquids (ILs) are widely used for biomass pretreatment because of their excellent dissolving capacity. The efficient and economical use of ILs in pretreatment greatly depends on revealing the underlying mechanism of biomass dissolution.

Microfibrils are supramolecular structures ubiquitously found in the extracellular matrix of elastic and nonelastic tissues. The three members of the cysteine-rich fibrillin family constitute the core of microfibrils. Mutations in fibrillin-1 and -2 lead to a number of heritable connective tissue disorders termed fibrillinopathies.

Structure of the α-keratin microfibril
Journal of Molecular Biology, 1976The fine detail in the X-ray diffraction pattern of α-keratin has been explored out to spacings of 4 A by a direct mapping of the cylindrically averagedintensity transform. The meridional maxima lie on a set of layer lines corresponding to an axially projected repeat of structure of 470 A, and the distribution of nonmeridional maxima is consistent with

On the ultrastructure of cellulose microfibrils
Journal of Polymer Science Part A: General Papers, 1965AbstractStatistical formulae based on generally accepted models for cellulose microfibril structure were developed to calculate the mean length of microfibril segments which do not contain molecular chain‐ends, i.e., “continuous segments.” The calculated length of such “continuous segments” for microfibrils of 2–3 mμ cross section, containing molecules

A note on microfibrils in polyethylene
Journal of Macromolecular Science, Part B, 1974Abstract The results of diffraction (low-angle scattering of X-rays and electrons) and electron microscopy study show a significant qualitative coincidence in studies of the morphology of oriented polyethylene films obtained from polyethylene single crystal mats. The morphology approximates the ideal description of a microfibrillar structure.

Possible Roles of Microfibrils in Elastogenesis
Connective Tissue Research, 1981On examination in the electron microscope elastic tissue is seen to consist of an amorphous component surrounded by microfibrillar components. The exact relationship between these components is unknown, although during development the microfibrils appear before the amorphous material.

Mechanical performance and cellulose microfibrils in wood with high S2 microfibril angles
Journal of Materials Science, 2010Corewood and compression wood, both with high S2 microfibril angles, are the worst parts of the tree most in need of improvement in wood quality. This study focuses on the characteristics of cellulosic reinforcement in wood with high S2 microfibril angles lying between 35° and 60°, as well as the probable influence of these characteristics on wood ...

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 ...

Exploring the Nature of Cellulose Microfibrils
Biomacromolecules, 2015Ultrathin cellulose microfibril fractions were extracted from spruce wood powder using combined delignification, TEMPO-catalyzed oxidation, and sonication processes. Small-angle X-ray scattering of these microfibril fractions in a "dilute" aqueous suspension (concentration 0.077 wt %) revealed that their shape was in the form of nanostrip with 4 nm ...

Solvation of a Cellulose Microfibril in Imidazolium Acetate Ionic Liquids: Effect of a Cosolvent.
Journal of Physical Chemistry B, 2014The solvation and the onset of dissolution of a cellulose I(β) microcrystal in ionic liquid media are studied by molecular simulation. Ionic liquids can dissolve large amounts of cellulose, which can later be regenerated from solution, but their high ...
