Comparative assessment of methods for producing cellulose I nanocrystals from cellulosic sources
(American Chemical Society, 2017)Current environmental concerns foster a strong interest in extracting polymers and building-blocks from lignocellulosic biomass. Among these, cellulose nanocrystals (CNCs) have raised both academic and industrial interest ... -
Enzymatic hydrolysis of cellulose and the use of TiO2 nanoparticles to open up the cellulose structure
(Pergamon, 2011-10)A major barrier in the process of cellulose enzymatic hydrolysis into glucose for biofuel production is the enzyme accessibility to cellulose. In this study, a new cellulose regeneration strategy is developed to address ... -
Ionic liquid-mediated technology to produce cellulose nanocrystals directly from wood
(Elsevier, 2015-09)We report for the first time the direct extraction of cellulose nanocrystals (CNCs) from wood by means of a 1-ethyl-3-methylimidazolium acetate ([EMIM][OAc]) treatment. A native cellulosic product could be recovered in 44% ... -
Microcrystalline cellulose powder tableting via networked cellulose-based gel material
(Elsevier, 2012-02)Networked cellulosic (NC) gel material was prepared via 70% sulfuric acid dissolution and hydrolysis of microcrystalline cellulose (MCC) followed by regeneration in cold ethanol. The material was utilized as a multifunctional ... -
Networked cellulosic gel material as a pharmaceutical excipient
(Masdar Institute of Science and Technology, 2012)Networked cellulosic (NC) material was prepared in a gel form via sulfuric acid dissolution and hydrolysis of microcrystalline cellulose (MCC) and then regeneration in ethanol. The regenerated material was utilized ... -
Swelling and hydrolysis kinetics of Kraft pulp fibers in aqueous 1-butyl-3-methylimidazolium hydrogen sulfate solutions
(Elsevier, 2016-11)1Butyl-3-methylimidazolium hydrogen sulfate ([Bmim]HSO4) is efficient at extracting cellulose nanocrystals from pulp fibers. To shed some light on the respective contributions of swelling and hydrolysis of pulp fibers by ...
