CELLULOSE NANOCRYSTALS FROM BACTERIAL CELLULOSE
(Soc Brasileira Quimica, 2015-11-01)
Bacterial cellulose produced from Gluconacetobacter xilinus was used to produce cellulose nanocrystals by sulfuric acid hydrolysis. Hydrolysis was performed with 64% sulfuric acid at 50 degrees C with the hydrolysis time ...
Combining steam explosion with 1-ethyl-3-methylimidazlium acetate treatment of wood yields lignin-coated cellulose nanocrystals of high aspect ratio
(Springer, 2016-06-01)
Lignin-coated cellulose nanocrystals (CNCs) were extracted from the tropical wood Angelim Vermelho in a yield of 47 % based on wood cellulose content. The procedure combined a mild steam explosion process with a treatment ...
Characterization of Cellulose Nanocrystals Grafted with Organic Acid Chloride of Different Sizes
(Scrivener Publishing Llc, 2014-12-01)
In the work presented in this article surface chemical modification was applied to ramie cellulose nanocrystals by grafting organic acid chlorides presenting different lengths of the aliphatic chain. The objective of this ...
Kinetic study of the thermal decomposition of cellulose nanocrystals with different polymorphs, cellulose I and II, extracted from different sources and using different types of acids
(Elsevier B.V., 2015-12-15)
Cellulose nanocrystals (CNs) were extracted from different sources by acid hydrolysis using H2SO4 and HCI. The thermal decomposition of resulting CNs was studied by thermogravimetric analysis (TGA). The kinetic parameters ...
Simple citric acid-catalyzed surface esterification of cellulose nanocrystals
(Elsevier, 2017-02)
A simple straightforward route for the surface esterification of cellulose nanocrystals (CNC) is herein proposed. CNC obtained from microcrystalline cellulose were acetylated using as catalyst citric acid, a α-hydroxy acid ...
Mechanical, thermal, and barrier properties of methylcellulose/cellulose nanocrystals nanocomposites
(2014)
In this work, the effects of incorporating cellulose nanocrystals from soy hulls (WSH30) on the mechanical, thermal, and barrier properties of methylcellulose (MC) nanocomposites were evaluated. MC/WSH30 nanocomposite films ...
Nanocellulose patents trends: a comprehensive review on patents on cellulose nanocrystals, microfibrillated and bacterial cellulose
(Bentham Science Publishers, 2013-01)
Cellulose nanoparticles (i.e. cellulose elements having at least one dimension in the 1-100nm range) have received increasing attention during the last decade. This is not only evident in academic articles, but it is also ...
A MINIREVIEW OF CELLULOSE NANOCRYSTALS AND ITS POTENTIAL INTEGRATION AS CO-PRODUCT IN BIOETHANOL PRODUCTION
(Sociedad Chilena de Química, 2011)
Surface modification of cotton nanocrystals with a silane agent
(SpringerDordrechtHolanda, 2013)
