Deciphering Branched Galactomannan Structures via Multistage Ion Mobility MS and MSn Fragmentation (Multistage IMSn)

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Hemicelluloses are abundant carbohydrate components in plant cell walls. They play a crucial structural role in binding cellulose microfibrils, in addition to other biological functions. Their high structural variability directly influences their biological properties, making it important to establish a structure–function ...

Cellulose microfibril-water interaction as characterized by isothermal thermogravimetric analysis and scanning electron microscopy [PDF]

BioResources, 2012
Microfibrillated celluloses, liberated from macroscopic lignocellulosic fibers by mechanical means, are sub-fiber elements with lengths in the micron scale and diameters ranging from 10 to a few hundred nanometers. These materials have shown strong water

Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

High Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

The structure of the α-keratin microfibril

Bioscience Reports, 1983
Quantitative measurements of the intensity of the meridional reflections in the X-ray-diffraction pattern of α-keratin are shown to be consistent with a microfibril structure in which a surface lattice with an axially projected period around 200 Å is subject to a periodic interruption with an axially projected period of 470 Å. Taken in conjunction with

Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

High Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic

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-
