Slow crack growth : models and experiments [PDF]

, 2007
The properties of slow crack growth in brittle materials are analyzed both theoretically and experimentally. We propose a model based on a thermally activated rupture process.

From nano- to micrometer scale: the role of microwave-assisted acid and alkali pretreatments in the sugarcane biomass structure

Biotechnology for Biofuels, 2018
Background To date, great strides have been made in elucidating the role of thermochemical pretreatments in the chemical and structural features of plant cell walls; however, there is no clear picture of the plant recalcitrance and its relationship to ...

Role of Polysaccharides on Mechanical and Adhesion Properties of Flax Fibres in Flax/PLA Biocomposite

International Journal of Polymer Science, 2011
The effect of alkali and enzymatic treatments on flax fibre morphology, mechanical, and adhesion properties was investigated. The multilength scale analysis allows for the correlation of the fibre's morphological changes induced by the treatments with ...

Unravelling the nanostructure of cellulose microfibrils [PDF]

Acta Crystallographica Section A Foundations and Advances, 2014
Cellulose is the most abundant naturally occurring polymer and has diverse applications in biology, energy and engineering. The cellulose nanostructure has implications on the mechanical strength of natural materials such as wood and nanocelluloses are also being used to create high-performance composite materials with properties comparable to aramid ...

A medium supplemented with vegetable extract used for cellulose production of Rhodococcus SP. MI 2

Bioscience Journal, 2018
In this study, the most suitable vegetable extract was screened to use as non-conventional nutrient sources for cellulose production of Rhodococcus sp. MI 2. SH medium or a synthetic medium was used as a conventional or control medium.

Fabrication of Ionic Cellulose Nanofiber Composites by Electrospinning Cellulose Microfibril-Gel-Dispersions in Poly(vinyl Alcohol) Solution

Journal of Natural Fibers, 2022
In this study, we propose a fabrication method to obtain composites of poly(vinyl alcohol) (PVA)/ionic cellulose nanofibers, in which a fiber structure is manipulated through a reconstruction of 2,2,6,6-tetramethyl-piperidinyl-1-oxyl radical (TEMPO ...
