Cellulose swelling by protic solvents: which properties of the biopolymer and the solvent matter?
(SPRINGER, 2008)
The question posed in the title has been addressed by studying the swelling of celluloses at 20 C by twenty protic solvents, including water; linear- and branched-chain aliphatic alcohols; unsaturated aliphatic alcohols, ...
New promising composite materials useful in the adsorption of Cu(II) in ethanol based on cellulose and cellulose acetate
(SpringerDordrechtHolanda, 2012)
Thermal characterization of bacterial cellulose-phosphate composite membranes
(Springer, 2007-03-01)
Cellulose-phosphate composite membranes have been prepared from bacterial cellulose membranes ( BC) and sodium polyphosphate solution. The structure and thermal behavior of the new composites were evaluated by X-ray ...
Kinetic parameters for thermal decomposition of microcrystalline, vegetal, and bacterial cellulose
(Springer, 2011-08-01)
Cellulose can be obtained from innumerable sources such as cotton, trees, sugar cane bagasse, wood, bacteria, and others. The bacterial cellulose (BC) produced by the Gram-negative acetic-acid bacterium Acetobacter xylinum ...

Probing the dependence of the properties of cellulose acetates and their films on the degree of biopolymer substitution: use of solvatochromic indicators and thermal analysis
(SPRINGER, 2010)
Although cellulose acetates, CAs, are extensively employed there is scant information about the systematic dependence of their properties on their degree of substitution, DS; this is the subject of the present work. Nine ...
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 ...
ZIRCONIUM DIOXIDE SUPPORTED ON ALPHA-CELLULOSE - SYNTHESIS AND CHARACTERIZATION
(Amer Chemical SocWashington, 1994)
A physical organic chemistry approach to dissolution of cellulose: effects of cellulose mercerization on its properties and on the kinetics of its decrystallization
(ARKAT USA INC, 2011)
The effects of alkali treatment on the structural characteristics of cotton linters and sisal cellulose samples have been studied. Mercerization results in a decrease in the indices of crystallinity and the degrees of ...
