What makes cellulose auxetic?
2016 - IRG/WP 16-40767
The 1D bundles of cellulose microfibrils (lignified flax fibre) and 2D networks of cellulose mi-crofibrils form tunicate, bacterial and microfibrillated celluloses were strained in tension, and their molecular deformation followed by Raman spectroscopy in order to fully understand the origins and magnitudes of in-plane auxetics for the information of innovation. Cellulose is found to exhibit three...

Reactivity of alkoxysilanes with cellulose and lignin in presence of catalysts
2018 - IRG/WP 18-40831
The origin of research was another step in development of a new conservation method for wood cultural heritage. Wood silanisation seemed to be an alternative method to waterlogged wood PEG treatment. The superior aim from the practical point of view was to increase dimensional stability and reduce the hygroscopicity of archaeological wood. The aim of the study was to identify interactions between ...

A novel cellulose-binding domain from the brown-rot fungus Gloeophyllum trabeum
2023 - IRG/WP 23-11019
Wood-rotting basidiomycetes are the major organisms decomposing wood in nature. They are classified into two groups based on their decay modes; white-rot fungi and brown-rot fungi. White-rot fungi secrete various cellulolytic enzymes during the wood degradation process. The enzymes are known to be often appended with a cellulose binding domain (CBD) which assists the activity of catalytic domain. ...

The cellulose binding mechanism of a novel cellulose binding domain from the brown-rot fungus Gloeophyllum trabeum
2023 - IRG/WP 23-11021
In nature, wood decay is caused by various wood-rotting basidiomycetes. Wood-rotting basidiomycete are mainly divided into white-rot fungi and brown-rot fungi. Their main carbon source is cellulose of the wood cell wall during wood decay, and they produce a variety of enzymes to decompose cellulose. The cellulolytic enzymes often possess a cellulose binding domain (CBD) as an additional domain con...

A novel cellulose-binding domain from the brown-rot fungus that can be used to evaluate cellulose in wood
2024 - IRG/WP 24-11046
Wood-rotting basidiomycetes are the primary microorganisms that decay wood in nature. They are classified as white-rot fungi and brown-rot fungi by the difference in decaying types. White-rot fungi secrete a variety of cellulolytic enzymes during wood degradation. These enzymes often have an additional cellulose-binding domain (CBD) that adsorbs to the cellulose surface and localizes the catalytic...

Binder-free, fire-resistant, light-weight fiberboard materials encrusted with expandable graphite and borax
2024 - IRG/WP 24-20714
Despite abundant data on innovative fire protection technologies tailored for wood and lignocellulosic materials, the prevailing approach revolves around the formulation of fire retardant solutions employing water-soluble salts, e.g., phosphorus or boron compounds. On the other hand, additives fostering the formation of a char layer during the combustion of lignocellulosic materials as a non-leach...
